109-626: The line's name comes from Osaka ( 大阪 ) (the kanji character for saka is also pronounced han ) and Sakai ( 堺 ) (whose kanji contributed the kai ). The Hankai Line has its origin in the Hankai Tramway Co., Ltd., founded in 1910. In 1915 the company merged with the Nankai Railway which runs north and south in Osaka. The city's overall tram network was once extensive. As motorization developed as an alternative form of transportation along with

218-413: A kun -reading) ; kun -only are common for Japanese-coined kanji ( kokuji ). Some common kanji have ten or more possible readings; the most complex common example is 生 , which is read as sei , shō , nama , ki , o-u , i-kiru , i-kasu , i-keru , u-mu , u-mareru , ha-eru , and ha-yasu , totaling eight basic readings (the first two are on , while

327-536: A ⟨g⟩ element to encode any non-standard character or glyph, including gaiji. The g stands for gaiji . There is no definitive count of kanji characters, just as there is none of Chinese characters generally. The Dai Kan-Wa Jiten , which is considered to be comprehensive in Japan, contains about 50,000 characters. The Zhonghua Zihai , published in 1994 in China, contains about 85,000 characters, but

436-408: A speaking tube . In the U.S., a somewhat dated slang term refers to the telephone as "the horn," as in "I couldn't get him on the horn," or "I'll be off the horn in a moment." Early telephones were technically diverse. Some used a water microphone , some had a metal diaphragm that induced current in an electromagnet wound around a permanent magnet, and some were dynamic – their diaphragm vibrated

545-496: A DC transformer which plugs into a wall AC power outlet. A mobile phone or cellphone or hand phone is a handheld telephone which connects via radio transmissions to a cellular telephone network . The cellular network consists of a network of ground based transmitter/receiver stations with antennas – which are usually located on towers or on buildings – and infrastructure connecting to the global telecommunications network. Analog cellular networks first appeared in 1979, followed by

654-516: A Japanese railway line–related topic is a stub . You can help Misplaced Pages by expanding it . Kanji Kanji ( 漢字 , Japanese pronunciation: [kaɲdʑi] ) are the logographic Chinese characters adapted from the Chinese script used in the writing of Japanese . They were made a major part of the Japanese writing system during the time of Old Japanese and are still used, along with

763-490: A coil of wire in the field of a permanent magnet or the coil vibrated the diaphragm. The sound-powered dynamic variants survived in small numbers through the 20th century in military and maritime applications, where its ability to create its own electrical power was crucial. Most, however, used the Edison/Berliner carbon transmitter , which was much louder than the other kinds, even though it required an induction coil which

872-429: A combination of a mobile phone and a personal computing device in the same unit. Most smartphones are primarily operated using a graphical user interface and a touch screen. Many phones have a secondary voice user interface, such as Siri on Apple iPhones , which can operate many of the device's functions, as well as enabling users to use spoken commands to interact with the internet. Typically alphanumeric text input

981-422: A common battery exchange had a magneto hand-cranked generator to produce a high voltage alternating signal to ring the bells of other telephones on the line and to alert the operator. Some local farming communities that were not connected to the main networks set up barbed wire telephone lines that exploited the existing system of field fences to transmit the signal. In the 1890s a new smaller style of telephone

1090-413: A display for caller ID . In addition, answering machine function may be built in. The cordless handset contains a rechargeable battery , which the base station recharges when the handset rests in its cradle. Muilt-handset systems generally also have additional charging stands. A cordless telephone typically requires a constant electricity supply to power the base station and charger units by means of

1199-479: A home and a shop. Users who wanted the ability to speak to several different locations would need to obtain and set up three or four pairs of telephones. Western Union , already using telegraph exchanges, quickly extended the principle to its telephones in New York City and San Francisco , and Bell was not slow in appreciating the potential. Signalling began in an appropriately primitive manner. The user alerted

1308-737: A label for its sound), kanji are also called mana ( 真名 , literally "true name", in reference to the character being used as a label for its meaning). In modern Japanese, kanji are used to write certain words or parts of words (usually content words such as nouns , adjective stems , and verb stems ), while hiragana are used to write inflected verb and adjective endings, phonetic complements to disambiguate readings ( okurigana ), particles , and miscellaneous words which have no kanji or whose kanji are considered obscure or too difficult to read or remember. Katakana are mostly used for representing onomatopoeia , non-Japanese loanwords (except those borrowed from ancient Chinese ),

1417-510: A large number of web services and web apps, giving them functionality similar to traditional computers, although smartphones are often limited by their relatively small screen size and the size of their keyboards. Typically, smartphones feature such tools as cameras, media players, web browsers, email clients, interactive maps, satellite navigation and a variety of sensors, such as a compass , accelerometers and GPS receivers . In addition to voice calls, smartphone users commonly communicate using

1526-454: A long gairaigo word may be the reading (this is classed as kun'yomi —see single character gairaigo , below)—the character 糎 has the seven kana reading センチメートル senchimētoru "centimeter", though it is generally written as "cm" (with two half-width characters, so occupying one space); another common example is '%' (the percent sign), which has the five kana reading パーセント pāsento . There are many kanji compounds that use

1635-614: A mixture of on'yomi and kun'yomi , known as jūbako ( 重箱 , multi-layered food box) or yutō ( 湯桶 , hot liquid pail) words (depending on the order), which are themselves examples of this kind of compound (they are autological words ): the first character of jūbako is read using on'yomi , the second kun'yomi ( on-kun , Japanese : 重箱読み ). It is the other way around with yu-tō ( kun-on , Japanese : 湯桶読み ). Formally, these are referred to as jūbako-yomi ( 重箱読み , jūbako reading) and yutō-yomi ( 湯桶読み , yutō reading) . In both these words,

1744-576: A new industry comprising many VoIP companies that offer services to consumers and businesses . The reported global VoIP market in October 2021 was $ 85.2 billion with a projection of $ 102.5 billion by 2026. IP telephony uses high-bandwidth Internet connections and specialized customer premises equipment to transmit telephone calls via the Internet, or any modern private data network. The customer equipment may be an analog telephone adapter (ATA) which translates

1853-430: A new kanji spelling is produced. Most often the word is a noun, which may be a simple noun (not a compound or derived from a verb), or may be a verb form or a fusional pronunciation. For example, the word 相撲 ( sumō , “ sumo ”) is originally from the verb 争う ( sumau , “to vie, to compete”), while 今日 ( kyō , “today”) is fusional (from older ke , “this” + fu , “day”). In rare cases, jukujikun

1962-520: A number of Chinese characters for their sound, rather than for their meaning. Man'yōgana written in cursive style evolved into hiragana (literally "fluttering kana " in reference to the motion of the brush during cursive writing), or onna-de , that is, "ladies' hand", a writing system that was accessible to women (who were denied higher education ). Major works of Heian-era literature by women were written in hiragana . Katakana (literally "partial kana ", in reference to

2071-446: A primary method for Internet-based communication but also a central feature of modern mobile communication infrastructure. While traditional analog telephones are typically powered from the central office through the telephone line, digital telephones require a local power supply. Internet-based digital service also requires special provisions to provide the service location to the emergency services when an emergency telephone number

2180-531: A problem for information interchange, as the code point used to represent an external character will not be consistent from one computer or operating system to another. Gaiji were nominally prohibited in JIS X 0208-1997 where the available number of code-points was reduced to only 940. JIS X 0213-2000 used the entire range of code-points previously allocated to gaiji , making them completely unusable. Most desktop and mobile systems have moved to Unicode negating

2289-516: A process similar to China 's simplification efforts , with the intention to increase literacy among the general public. Since the 1920s, the Japanese government has published character lists periodically to help direct the education of its citizenry through the myriad Chinese characters that exist. There are nearly 3,000 kanji used in Japanese names and in common communication . The term kanji in Japanese literally means " Han characters". It

2398-456: A profound influence in shaping Japanese culture, language, literature, history, and records. Inkstone artifacts at archaeological sites dating back to the earlier Yayoi period were also found to contain Chinese characters. Although some characters, as used in Japanese and Chinese, have similar meanings and pronunciations, others have meanings or pronunciations that are unique to one language or

2507-431: A separate enclosure, called the subscriber set. The dial switch in the base interrupted the line current by repeatedly but very briefly disconnecting the line one to ten times for each digit, and the hook switch (in the center of the circuit diagram) disconnected the line and the transmitter battery while the handset was on the cradle. In the 1930s, telephone sets were developed that combined the bell and induction coil with

2616-404: A short distance from the base station. Base stations include a radio transceiver which enables full-duplex, outgoing and incoming signals and speech with the handsets. The base station often includes a microphone, audio amplifier , and a loudspeaker to enable hands-free speakerphone conversations, without needing to use a handset. The base station may also have a numeric keypad for dialing, and

2725-399: A single word will have many such kanji spellings. An extreme example is hototogisu ( lesser cuckoo ) , which may be spelt in many ways, including 杜鵑 , 時鳥 , 子規 , 不如帰 , 霍公鳥 , 蜀魂 , 沓手鳥 , 杜宇 , 田鵑 , 沓直鳥 , and 郭公 —many of these variant spellings are particular to haiku poems. Telephone A telephone , colloquially referred to as a phone ,

2834-665: A small integrated circuit which stores the user's international mobile subscriber identity (IMSI) number and its related key, which are used to identify and authenticate subscribers to the cellular network. Mobile phones generally incorporate an LCD or OLED display, with some types, such as smartphones, having touch screens. Since the 1990s, mobile phones have gained other features which are not directly related to their primary function as telephones. These include text messaging, calendars, alarm clocks, personal schedulers, cameras, music players, games and later, internet access and smartphone functionality. Nearly all mobile phones have

2943-450: A surname). This phenomenon is observed in animal names that are shortened and used as suffixes for zoological compound names, for example when 黄金虫 , normally read as koganemushi , is shortened to kogane in 黒黄金虫 kurokogane , although zoological names are commonly spelled with katakana rather than with kanji. Outside zoology, this type of shortening only occurs on a handful of words, for example 大元帥 daigen(sui) , or

3052-428: A telephone are a microphone ( transmitter ) to speak into and an earphone ( receiver ) which reproduces the voice at a distant location. The receiver and transmitter are usually built into a handset which is held up to the ear and mouth during conversation. The transmitter converts the sound waves to electrical signals which are sent through the telecommunications system to the receiving telephone, which converts

3161-617: A total of 2,528 characters, showing the standard for kanji used by ministries and agencies and in general society. In 1946, after World War II and under the Allied Occupation of Japan , the Japanese government, guided by the Supreme Commander of the Allied Powers , instituted a series of orthographic reforms, to help children learn and to simplify kanji use in literature and periodicals. The number of characters in circulation

3270-469: A unique telephone number. While mobile and landline services are fully integrated into the public switched telephone network (PSTN), some Internet-based services, such as VoIP, may not always be directly connected to the PSTN, though they still allow communication across different systems when a connection is made. This ensures that a telephone number can be used universally to connect individuals globally. Before

3379-515: A wide variety of messaging formats, including SMS, MMS, email, and various proprietary messaging services, such as iMessage and various social media platforms. In 2002, only 10% of the world's population used mobile phones and by 2005 that percentage had risen to 46%. By the end of 2009, there were a total of nearly 6 billion mobile and fixed-line telephone subscribers worldwide. This included 1.26 billion fixed-line subscribers and 4.6 billion mobile subscribers. A satellite telephone, or satphone,

3488-427: Is jukujikun for tonakai , from Ainu, but the on'yomi reading of junroku is also used. In some cases, Japanese coinages have subsequently been borrowed back into Chinese , such as 鮟鱇 ( ankō , “ monkfish ”). The underlying word for jukujikun is a native Japanese word or foreign borrowing, which either does not have an existing kanji spelling (either kun'yomi or ateji ) or for which

3597-401: Is a telecommunications device that permits two or more users to conduct a conversation when they are too far apart to be easily heard directly. A telephone converts sound , typically and most efficiently the human voice , into electronic signals that are transmitted via cables and other communication channels to another telephone which reproduces the sound to the receiving user. The term

3706-401: Is a reading based on the pronunciation of a native Japanese word, or yamato kotoba , that closely approximated the meaning of the Chinese character when it was introduced. As with on'yomi , there can be multiple kun'yomi for the same kanji, and some kanji have no kun'yomi at all. Ateji ( 当て字 ) are characters used only for their sounds. In this case, pronunciation

3815-534: Is a type of mobile phone that connects to other phones or the telephone network by radio link through satellites orbiting the Earth instead of terrestrial cell sites , as cellphones do. Therefore, they can work in most geographic locations on the Earth's surface, as long as open sky and the line-of-sight between the phone and the satellite is provided. Depending on the architecture of a particular system, coverage may include

3924-610: Is accomplished via an on-screen virtual keyboard, although some smartphones have a small physical keyboard. Smartphones offer the ability to access internet data through the cellular network and via wi-fi, and usually allow direct connectivity to other devices via Bluetooth or a wired interface, such as USB or Lightning connectors. Smartphones, being able to run apps , have vastly expanded functionality compared to previous mobile phones. Having internet access and built in cameras, smartphones have made video calling readily accessible via IP connections. Smartphones also have access to

4033-534: Is also applied to inflectional words (verbs and adjectives), in which case there is frequently a corresponding Chinese word. The most common example of an inflectional jukujikun is the adjective 可愛い ( kawai-i , “cute”), originally kawafayu-i ; the word ( 可愛 ) is used in Chinese , but the corresponding on'yomi is not used in Japanese. By contrast, "appropriate" can be either 相応しい ( fusawa-shii , as jukujikun ) or 相応 ( sōō , as on'yomi ). Which reading to use can be discerned by

4142-400: Is called. A cordless telephone or portable telephone consists of a base station unit and one or more portable cordless handsets . The base station connects to a telephone line, or provides service by voice over IP (VOIP). The handset communicates with the base station via radio frequency signals. A handset's operational range is limited, usually to within the same building or within

4251-529: Is derived from Ancient Greek : τῆλε , romanized :  tēle , lit.   'far' and φωνή ( phōnē , voice ), together meaning distant voice . In 1876, Alexander Graham Bell was the first to be granted a United States patent for a device that produced clearly intelligible replication of the human voice at a second device. This instrument was further developed by many others, and became rapidly indispensable in business , government , and in households . The essential elements of

4360-485: Is derived from the Greek : τῆλε , tēle , "far" and φωνή, phōnē , "voice", together meaning "distant voice". Credit for the invention of the electric telephone is frequently disputed. As with other influential inventions such as radio , television , the light bulb , and the computer , several inventors pioneered experimental work on voice transmission over a wire and improved on each other's ideas. New controversies over

4469-567: Is determined by contextual cues (such as whether the character represents part of a compound word versus an independent word), the exact intended meaning of the word, and its position within the sentence. For example, 今日 is mostly read kyō , meaning "today", but in formal writing it is instead read konnichi , meaning "nowadays", which is understood from context. Furigana is used to specify ambiguous readings, such as rare, literary, or otherwise non-standard readings. This ambiguity may arise due to more than one reading becoming activated in

Hankai Line - Misplaced Pages Continue

4578-953: Is still based on a standard reading, or used only for meaning (broadly a form of ateji , narrowly jukujikun ). Therefore, only the full compound—not the individual character—has a reading. There are also special cases where the reading is completely different, often based on a historical or traditional reading. The analogous phenomenon occurs to a much lesser degree in Chinese varieties , where there are literary and colloquial readings of Chinese characters —borrowed readings and native readings. In Chinese these borrowed readings and native readings are etymologically related, since they are between Chinese varieties (which are related), not from Chinese to Japanese (which are not related). They thus form doublets and are generally similar, analogous to different on'yomi , reflecting different stages of Chinese borrowings into Japanese. Longer readings exist for non- Jōyō characters and non-kanji symbols, where

4687-606: Is the address of the call recipient's telephone in the telecommunications system, but other methods existed in the early history of the telephone. The first telephones were directly connected to each other from one customer's office or residence to another customer's location. Being impractical beyond just a few customers, these systems were quickly replaced by manually operated centrally located switchboards . These exchanges were soon connected together, eventually forming an automated, worldwide public switched telephone network . For greater mobility, various radio systems were developed in

4796-415: Is written in Japanese by using the same characters as in traditional Chinese , and both refer to the character writing system known in Chinese as hanzi ( traditional Chinese : 漢字 ; simplified Chinese : 汉字 ; pinyin : hànzì ; lit. ' Han characters'). The significant use of Chinese characters in Japan first began to take hold around the 5th century AD and has since had

4905-516: The Nihon Shoki and Kojiki , a semi-legendary scholar called Wani was dispatched to Japan by the (Korean) Kingdom of Baekje during the reign of Emperor Ōjin in the early fifth century, bringing with him knowledge of Confucianism and Chinese characters. The earliest Japanese documents were probably written by bilingual Chinese or Korean officials employed at the Yamato court. For example,

5014-406: The kyōiku kanji, plus 1,110 additional kanji taught in junior high and high school. In publishing, characters outside this category are often given furigana . The jōyō kanji were introduced in 1981, replacing an older list of 1,850 characters known as the tōyō kanji ( 当用漢字 , general-use kanji) , introduced in 1946. Originally numbering 1,945 characters, the jōyō kanji list

5123-474: The on'yomi has a long vowel; long vowels in Japanese generally are derived from sound changes common to loans from Chinese, hence distinctive of on'yomi . These are the Japanese form of hybrid words . Other examples include basho ( 場所 , "place", kun-on , 湯桶読み ) , kin'iro ( 金色 , "golden", on-kun , 重箱読み ) and aikidō ( 合気道 , the martial art Aikido ", kun-on-on , 湯桶読み ) . Ateji often use mixed readings. For instance,

5232-555: The Internet , giving rise to the field of Internet Protocol (IP) telephony, also known as voice over Internet Protocol (VoIP). VoIP has proven to be a disruptive technology that is rapidly replacing traditional telephone network infrastructure. By January 2005, up to 10% of telephone subscribers in Japan and South Korea had switched to this digital telephone service. A January 2005 Newsweek article suggested that Internet telephony may be "the next big thing." The technology has spawned

5341-651: The Latin alphabet , Cyrillic script , Greek alphabet , Arabic numerals , etc. for use in information processing. They have had numerous revisions. The current standards are: Gaiji ( 外字 , literally "external characters") are kanji that are not represented in existing Japanese encoding systems . These include variant forms of common kanji that need to be represented alongside the more conventional glyph in reference works and can include non-kanji symbols as well. Gaiji can be either user-defined characters, system-specific characters or third-party add-on products. Both are

5450-444: The smartphone , the dominant type of telephone in the world today. Modern telephones exist in various forms and are implemented through different systems, including fixed-line , cellular , satellite , and Internet-based devices, all of which are integrated into a global telecommunication network. This interconnected system allows any telephone, regardless of its underlying technology or geographic location, to reach another through

5559-572: The 1,026 first kanji characters that Japanese children learn in elementary school, from first grade to sixth grade. The grade-level breakdown is known as the gakunen-betsu kanji haitōhyō ( 学年別漢字配当表 ) , or the gakushū kanji ( 学習漢字 ) . This list of kanji is maintained by the Japanese Ministry of Education and prescribes which kanji characters and which kanji readings students should learn for each grade. The jōyō kanji ( 常用漢字 , regular-use kanji) are 2,136 characters consisting of all

5668-481: The 7th century, a record of trading for cloth and salt. The Japanese language had no written form at the time Chinese characters were introduced, and texts were written and read only in Chinese. Later, during the Heian period (794–1185), a system known as kanbun emerged, which involved using Chinese text with diacritical marks to allow Japanese speakers to read Chinese sentences and restructure them into Japanese on

5777-610: The Chinese pronunciation but was not the Chinese pronunciation or reading itself, similar to the English pronunciation of Latin loanwords. There also exist kanji created by the Japanese and given an on'yomi reading despite not being a Chinese-derived or a Chinese-originating character. Some kanji were introduced from different parts of China at different times, and so have multiple on'yomi , and often multiple meanings. Kanji invented in Japan ( kokuji ) would not normally be expected to have on'yomi , but there are exceptions, such as

5886-419: The Japanese court. In ancient times, paper was so rare that people wrote kanji onto thin, rectangular strips of wood, called mokkan ( 木簡 ). These wooden boards were used for communication between government offices, tags for goods transported between various countries, and the practice of writing. The oldest written kanji in Japan discovered so far were written in ink on wood as a wooden strip dated to

5995-475: The ability to send text messages to other users via the SMS (Short Message Service) protocol. The multimedia messaging service (MMS) protocol enables users to send and receive multimedia content, such as photos, audio files and video files. As their functionality has increased over the years, many types of mobile phone, notably smartphones, require an operating system to run. Popular mobile phone operating systems in

6104-401: The assistance of a telephone operator. What turned out to be the most popular and longest-lasting physical style of telephone was introduced in the early 20th century, including Bell's 202-type desk set. A carbon granule transmitter and electromagnetic receiver were united in a single molded plastic handle, which when not in use was secured in a cradle in the base unit. The circuit diagram of

6213-404: The bell, induction coil, battery and magneto were in a separate bell box or " ringer box ". In phones connected to common battery exchanges, the ringer box was installed under a desk, or other out-of-the-way place, since it did not need a battery or magneto. Cradle designs were also used at this time, having a handle with the receiver and transmitter attached, now called a handset , separate from

6322-417: The brain. Kanji readings are categorized as either on'yomi ( 音読み , literally "sound reading" ) , from Chinese, or kun'yomi ( 訓読み , literally "meaning reading" ) , native Japanese, and most characters have at least two readings—at least one of each. However, some characters have only a single reading, such as kiku ( 菊 , "chrysanthemum", an on -reading) or iwashi ( 鰯 , "sardine",

6431-687: The broader sense "nowadays" or "current", such as 今日的 ("present-day"), although in the phrase konnichi wa ("good day"), konnichi is typically spelled wholly with hiragana rather than with the kanji 今日 . Jukujikun are primarily used for some native Japanese words, such as Yamato ( 大和 or 倭 , the name of the dominant ethnic group of Japan, a former Japanese province as well as ancient name for Japan), and for some old borrowings, such as 柳葉魚 ( shishamo , literally "willow leaf fish") from Ainu, 煙草 ( tabako , literally “smoke grass”) from Portuguese, or 麦酒 ( bīru , literally “wheat alcohol”) from Dutch, especially if

6540-409: The capacity, quality, and cost of the network. Integrated Services Digital Network (ISDN) was launched in the 1980's, providing businesses and consumers with access to digital telephony services such as data, voice, video , and fax services. The development of digital data communications methods made it possible to digitize voice and transmit it as real-time data across computer networks and

From the point of view of the character, rather than the word, this is known as a nankun ( 難訓 , "difficult reading") , and these are listed in kanji dictionaries under the entry for the character. Gikun are other readings assigned to a character instead of its standard readings. An example is reading 寒 (meaning "cold") as fuyu ("winter") rather than

The most common reading is kesa , a native bisyllabic Japanese word that may be seen as a single morpheme , or as a compound of ke (“this”, as in kefu , the older reading for 今日 , “today”), and asa , “morning”. Likewise, 今日 ("today") is also jukujikun , usually read with the native reading kyō ; its on'yomi , konnichi , does occur in certain words and expressions, especially in

By 1980, Hankai Tramway split from Nankai. Station numbers are in parentheses. All trams from Ebisucho go only as far as Abikomichi, while Uemachi Line trains go through from Tennoji-ekimae to Hamadera-ekimae. This article about

7194-470: The cradle base that housed the magneto crank and other parts. They were larger than the "candlestick" and more popular. Disadvantages of single-wire operation such as crosstalk and hum from nearby AC power wires had already led to the use of twisted pairs and, for long-distance telephones, four-wire circuits . Users at the beginning of the 20th century did not place long-distance calls from their own telephones but made an appointment and were connected with

7303-525: The desk set, obviating a separate ringer box. The rotary dial becoming commonplace in the 1930s in many areas enabled customer-dialed service, but some magneto systems remained even into the 1960s. After World War II, the telephone networks saw rapid expansion and more efficient telephone sets, such as the model 500 telephone in the United States, were developed that permitted larger local networks centered around central offices. A breakthrough new technology

7412-587: The development of the electric telephone, the term telephone was applied to other inventions, and not all early researchers of the electrical device used the term. Perhaps the earliest use of the word for a communications system was the telephon created by Gottfried Huth in 1796. Huth proposed an alternative to the optical telegraph of Claude Chappe in which the operators in the signaling towers would shout to each other by means of what he called "speaking tubes", but would now be called giant megaphones . A communication device for sailing vessels, called telephone ,

7521-484: The diplomatic correspondence from King Bu of Wa to Emperor Shun of Liu Song in 478 AD has been praised for its skillful use of allusion . Later, groups of people called fuhito were organized under the monarch to read and write Classical Chinese . During the reign of Empress Suiko (593–628), the Yamato court began sending full-scale diplomatic missions to China, which resulted in a large increase in Chinese literacy at

7630-402: The earliest Strowger switch automatic exchanges had seven wires, one for the knife switch , one for each telegraph key , one for the bell, one for the push-button and two for speaking. Large wall telephones in the early 20th century usually incorporated the bell, and separate bell boxes for desk phones dwindled away in the middle of the century. Rural and other telephones that were not on

7739-614: The entire Earth or only specific regions. Satellite phones provide similar functionality to terrestrial mobile telephones; voice calling , text messaging , and low-bandwidth Internet access are supported through most systems. The advantage of a satellite phone is that it can be used in such regions where local terrestrial communication infrastructures, such as landline and cellular networks, are not available. Satellite phones are popular on expeditions into remote locations, hunting, fishing, maritime sector, humanitarian missions, business trips, and mining in hard-to-reach areas, where there

7848-574: The entire word—rather than each part of the word being centered over its corresponding character, as is often done for the usual phono-semantic readings. Broadly speaking, jukujikun can be considered a form of ateji , though in narrow usage, " ateji " refers specifically to using characters for sound and not meaning (sound-spelling), whereas " jukujikun " refers to using characters for their meaning and not sound (meaning-spelling). Many jukujikun (established meaning-spellings) began as gikun (improvised meaning-spellings). Occasionally,

7957-462: The fly, by changing word order and adding particles and verb endings, in accordance with the rules of Japanese grammar . This was essentially a kind of codified sight translation . Chinese characters also came to be used to write texts in the vernacular Japanese language , resulting in the modern kana syllabaries. Around 650 AD, a writing system called man'yōgana (used in the ancient poetry anthology Man'yōshū ) evolved that used

8066-433: The historical male name suffix 右衛門 -emon , which was shortened from the word uemon . The kanji compound for jukujikun is often idiosyncratic and created for the word, and there is no corresponding Chinese word with that spelling. In other cases, a kanji compound for an existing Chinese word is reused, where the Chinese word and on'yomi may or may not be used in Japanese. For example, 馴鹿 (“reindeer”)

8175-465: The introduction of digital cellular networks in the early 1990s, marking the beginning of the GSM standard. Over time, these networks evolved, with each new generation ( 2G , 3G , 4G , and beyond) offering improved data transmission capabilities and more advanced features for mobile communication . Mobile phones require a SIM card to be inserted into the phone. The SIM card is a small PVC card containing

8284-518: The issue still arise from time to time. Charles Bourseul , Antonio Meucci , Johann Philipp Reis , Alexander Graham Bell , and Elisha Gray , amongst others, have all been credited with the invention of the telephone. Alexander Graham Bell was the first to be awarded a patent for the electric telephone by the United States Patent and Trademark Office (USPTO) in March 1876. Before Bell's patent,

8393-471: The limitation of kanji. After the Meiji Restoration and as Japan entered an era of active exchange with foreign countries, the need for script reform in Japan began to be called for. Some scholars argued for the abolition of kanji and the writing of Japanese using only kana or Latin characters. However, these views were not so widespread. However, the need to limit the number of kanji characters

8502-705: The majority of them are not in common use in any country, and many are obscure variants or archaic forms. A list of 2,136 jōyō kanji is regarded as necessary for functional literacy in Japanese. Approximately a thousand more characters are commonly used and readily understood by the majority in Japan and a few thousand more find occasional use, particularly in specialized fields of study but those may be obscure to most out of context. A total of 13,108 characters can be encoded in various Japanese Industrial Standards for kanji . Individual kanji may be used to write one or more different words or morphemes , leading to different pronunciations or "readings." The correct reading

8611-437: The mid-20th century for transmission between mobile stations on ships and in automobiles. Handheld mobile phones were introduced for personal service starting in 1973. In later decades, the analog cellular system evolved into digital networks with greater capability and lower cost. Convergence in communication services has provided a broad spectrum of capabilities in cell phones, including mobile computing, giving rise to

8720-412: The model 202 shows the direct connection of the transmitter to the line, while the receiver was inductively coupled. In local battery configurations, when the local loop was too long to provide sufficient current from the exchange, the transmitter was powered by a local battery and inductively coupled, while the receiver was included in the local loop. The coupling transformer and the ringer were mounted in

8829-482: The names of plants and animals (with exceptions), and for emphasis on certain words. Since ancient times, there has been a strong opinion in Japan that kanji is the orthodox form of writing, but there were also people who argued against it. Kamo no Mabuchi , a scholar of the Edo period , criticized the large number of characters in kanji. He also appreciated the small number of characters in kana characters and argued for

8938-407: The need for gaiji for most users. Nevertheless, they persist today in Japan's three major mobile phone information portals, where they are used for emoji (pictorial characters). Unicode allows for optional encoding of gaiji in private use areas , while Adobe's SING (Smart INdependent Glyphlets) technology allows the creation of customized gaiji. The Text Encoding Initiative uses

9047-604: The original list published in 1952, but new additions have been made frequently. Sometimes the term jinmeiyō kanji refers to all 2,999 kanji from both the jōyō and jinmeiyō lists combined. Hyōgai kanji ( 表外漢字 , "unlisted characters") are any kanji not contained in the jōyō kanji and jinmeiyō kanji lists. These are generally written using traditional characters, but extended shinjitai forms exist. The Japanese Industrial Standards for kanji and kana define character code-points for each kanji and kana , as well as other forms of writing such as

9156-468: The other end, or the exchange operator , by whistling into the transmitter. Exchange operation soon resulted in telephones being equipped with a bell in a ringer box , first operated over a second wire, and later over the same wire, but with a condenser ( capacitor ) in series with the bell coil to allow the AC ringer signal through while still blocking DC (keeping the phone " on hook "). Telephones connected to

9265-474: The other. For example, 誠 means 'honest' in both languages but is pronounced makoto or sei in Japanese, and chéng in Standard Mandarin Chinese . Individual kanji characters and multi-kanji words invented in Japan from Chinese morphemes have been borrowed into Chinese, Korean, and Vietnamese in recent times. These are known as Wasei-kango , or Japanese-made Chinese words. For example,

9374-579: The past have included Symbian , Palm OS , BlackBerry OS and mobile phone versions of Windows . As of 2022, the most used operating systems are Google's Android and Apple's iOS . Before the era of smartphones, mobile phones were generally manufactured by companies specializing in telecommunications equipment, such as Nokia , Motorola , and Ericsson . Since the advent of smartphones, mobile phone manufacturers have also included consumer electronics companies, such as Apple , Samsung and Xiaomi . As of 2022, most mobile phones are smartphones, being

9483-407: The practice of using a part of a kanji character) emerged via a parallel path: monastery students simplified man'yōgana to a single constituent element. Thus the two other writing systems, hiragana and katakana , referred to collectively as kana , are descended from kanji. In contrast with kana ( 仮名 , literally "borrowed name", in reference to the character being "borrowed" as

9592-594: The presence or absence of the -shii ending ( okurigana ). A common example of a verb with jukujikun is 流行る ( haya-ru , “to spread, to be in vogue”), corresponding to on'yomi 流行 ( ryūkō ). A sample jukujikun deverbal (noun derived from a verb form) is 強請 ( yusuri , “extortion”), from 強請る ( yusu-ru , “to extort”), spelling from 強請 ( kyōsei , “extortion”). Note that there are also compound verbs and, less commonly, compound adjectives, and while these may have multiple kanji without intervening characters, they are read using

9701-402: The readings contradict the kanji), or clarification if the referent may not be obvious. Jukujikun are when the standard kanji for a word are related to the meaning, but not the sound. The word is pronounced as a whole, not corresponding to sounds of individual kanji. For example, 今朝 ("this morning") is jukujikun . This word is not read as *ima'asa , the expected kun'yomi of

9810-475: The rest are kun ), or 12 if related verbs are counted as distinct. The on'yomi ( 音読み , [oɰ̃jomi] , lit. "sound(-based) reading") , the Sino-Japanese reading, is the modern descendant of the Japanese approximation of the base Chinese pronunciation of the character at the time it was introduced. It was often previously referred to as translation reading , as it was recreated readings of

9919-406: The signals into audible sound in the receiver or sometimes a loudspeaker . Telephones permit transmission in both directions simultaneously. Most telephones also contain an alerting feature, such as a ringer or a visual indicator, to announce an incoming telephone call. Telephone calls are initiated most commonly with a keypad or dial, affixed to the telephone, to enter a telephone number , which

10028-471: The signals of a conventional analog telephone; an IP Phone , a dedicated standalone device; or a computer softphone application, utilizing the microphone and headset devices of a personal computer or smartphone. In recent years, VoIP technology has evolved to integrate with mobile networks , including Voice over LTE ( VoLTE ) and Voice over 5G ( Vo5G ), enabling seamless voice communication over mobile data networks. These advancements have made VoIP not only

10137-575: The standard readings samu or kan , and instead of the usual spelling for fuyu of 冬 . Another example is using 煙草 (lit. "smoke grass") with the reading tabako ("tobacco") rather than the otherwise-expected readings of *kemuri-gusa or *ensō . Some of these, such as for tabako , have become lexicalized , but in many cases this kind of use is typically non-standard and employed in specific contexts by individual writers. Aided with furigana , gikun could be used to convey complex literary or poetic effect (especially if

10246-420: The subsequently-derived syllabic scripts of hiragana and katakana . The characters have Japanese pronunciations ; most have two, with one based on the Chinese sound. A few characters were invented in Japan by constructing character components derived from other Chinese characters. After the Meiji Restoration , Japan made its own efforts to simplify the characters, now known as shinjitai , by

10355-458: The telephone transmitted sound in a way that was similar to the telegraph. This method used vibrations and circuits to send electrical pulses, but was missing key features. Bell found that this method produced a sound through intermittent currents, but in order for the telephone to work a fluctuating current reproduced sounds the best. The fluctuating currents became the basis for the working telephone, creating Bell's patent. That first patent by Bell

10464-438: The user alternately listening and speaking (or rather, shouting) into the same hole. Sometimes the instruments were operated in pairs at each end, making conversation more convenient but also more expensive. At first, the benefits of a telephone exchange were not exploited. Instead, telephones were leased in pairs to a subscriber , who had to arrange for a telegraph contractor to construct a line between them, for example, between

10573-411: The usual kun'yomi . Examples include 面白い ( omo-shiro-i , “interesting”, literally “face + white”) and 狡賢い ( zuru-gashiko-i , “sly”, lit. “cunning, crafty + clever, smart”). Typographically, the furigana for jukujikun are often written so they are centered across the entire word, or for inflectional words over the entire root—corresponding to the reading being related to

10682-605: The word for telephone , 電話 denwa in Japanese, was derived from the Chinese words for "electric" and "conversation." It was then calqued as diànhuà in Mandarin Chinese, điện thoại in Vietnamese and 전화 jeonhwa in Korean. Chinese characters first came to Japan on official seals, letters, swords, coins, mirrors, and other decorative items imported from China . The earliest known instance of such an import

10791-721: The word was borrowed before the Meiji period . Words whose kanji are jukujikun are often usually written as hiragana (if native), or katakana (if borrowed); some old borrowed words are also written as hiragana , especially Portuguese loanwords such as かるた ( karuta ) from Portuguese " carta " (English “card”) or てんぷら ( tempura ) from Portuguese " tempora " (English “times, season”), as well as たばこ ( tabako ). Sometimes, jukujikun can even have more kanji than there are syllables, examples being kera ( 啄木鳥 , “woodpecker”), gumi ( 胡頽子 , “silver berry, oleaster”), and Hozumi ( 八月朔日 ,

10900-457: Was an impedance matching transformer to make it compatible with the impedance of the line. The Edison patents kept the Bell monopoly viable into the 20th century, by which time the network was more important than the instrument. Early telephones were locally powered, using either a dynamic transmitter or by the powering of a transmitter with a local battery. One of the jobs of outside plant personnel

11009-475: Was expanded to 2,136 in 2010. Some of the new characters were previously jinmeiyō kanji; some are used to write prefecture names: 阪 , 熊 , 奈 , 岡 , 鹿 , 梨 , 阜 , 埼 , 茨 , 栃 and 媛 . As of September 25, 2017, the jinmeiyō kanji ( 人名用漢字 , kanji for use in personal names) consists of 863 characters. Kanji on this list are mostly used in people's names and some are traditional variants of jōyō kanji. There were only 92 kanji in

11118-436: Was introduced, packaged in three parts. The transmitter stood on a stand, known as a " candlestick " for its shape. When not in use, the receiver hung on a hook with a switch in it, known as a "switchhook". Previous telephones required the user to operate a separate switch to connect either the voice or the bell. With the new kind, the user was less likely to leave the phone "off the hook". In phones connected to magneto exchanges,

11227-529: Was invented by Captain John Taylor in 1844. This instrument used four air horns to communicate with vessels in foggy weather. Johann Philipp Reis used the term in reference to his invention, commonly known as the Reis telephone , in c. 1860. His device appears to be the first device based on the conversion of sound into electrical impulses. The term telephone was adopted into the vocabulary of many languages. It

11336-526: Was reduced, and formal lists of characters to be learned during each grade of school were established. Some characters were given simplified glyphs , called shinjitai ( 新字体 ) . Many variant forms of characters and obscure alternatives for common characters were officially discouraged. These are simply guidelines, so many characters outside these standards are still widely known and commonly used; these are known as hyōgaiji ( 表外字 ) . The kyōiku kanji ( 教育漢字 , lit. "education kanji") are

11445-542: Was the King of Na gold seal given by Emperor Guangwu of Han to a Wa emissary in 57 AD. Chinese coins as well as inkstones from the first century AD have also been found in Yayoi period archaeological sites. However, the Japanese people of that era probably had little to no comprehension of the script, and they would remain relatively illiterate until the fifth century AD, when writing in Japan became more widespread. According to

11554-492: Was the master patent of the telephone, from which other patents for electric telephone devices and features flowed. In 1876, shortly after Bell's patent application, Hungarian engineer Tivadar Puskás proposed the telephone switch, which allowed for the formation of telephone exchanges , and eventually networks. In the United Kingdom, the blower is used as a slang term for a telephone. The term came from navy slang for

11663-591: Was the introduction of Touch-Tone signaling using push-button telephones by American Telephone & Telegraph Company (AT&T) in 1963. The invention of the transistor in 1947 dramatically changed the technology used in telephone systems and in the long-distance transmission networks, over the next several decades. With the development of stored program control and MOS integrated circuits for electronic switching systems , and new transmission technologies such as pulse-code modulation (PCM), telephony gradually evolved towards digital telephony , which improved

11772-423: Was to visit each telephone periodically to inspect the battery. During the 20th century, telephones powered from the telephone exchange over the same wires that carried the voice signals became common. Early telephones used a single wire for the subscriber's line, with ground return used to complete the circuit (as used in telegraphs ). The earliest dynamic telephones also had only one port opening for sound, with

11881-618: Was understood, and in May 1923, the Japanese government announced 1,962 kanji characters for regular use. In 1940, the Japanese Army decided on the "Table of Restricted Kanji for Weapons Names" ( 兵器名称用制限漢字表 , heiki meishō yō seigen kanji hyō ) which limited the number of kanji that could be used for weapons names to 1,235. In 1942, the National Language Council announced the "Standard Kanji Table" ( 標準漢字表 , hyōjun kanji-hyō ) with
