Kenjiro Takayanagi
was a Japanese engineer and a pioneer in the development of television. Although he failed to gain much recognition in the West, he built the world's first all-electronic television receiver, and is referred to as "the father of Japanese television". Career In 1925, Takayanagi began research on television after reading about the new technology in a French magazine. He developed a system similar to that of John Logie Baird, using a Nipkow disk to scan the subject and generate electrical signals. But unlike Baird, Takayanagi took the important step of using a cathode ray tube to display the received signal, thereby developing the first "all-electronic" television set. On December 25, 1926, Takayanagi successfully demonstrated his system at Hamamatsu Industrial High School, where he was teaching at the time (the school is now the Faculty of Engineering at Shizuoka University). The first picture he transmitted was of the Japanese katakana character made up of 40 scan lines. This was ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Order Of The Sacred Treasure
The is a Japanese order, established on 4 January 1888 by Emperor Meiji as the Order of Meiji. Originally awarded in eight classes (from 8th to 1st, in ascending order of importance), since 2003 it has been awarded in six classes, the lowest two medals being abolished that year. Originally a male-only decoration, the order has been made available to women since 1919. The Order of the Sacred Treasure, which had 8 ranks until 2003, was awarded as a slightly lower rank than the Order of the Rising Sun for men and the Order of the Precious Crown for women. For example, the 1st class of the Order of the Sacred Treasure has been treated as between the 1st class and the 2nd class of the Order of the Rising Sun and the Order of the Precious Crown, and the 2nd class of the Order of the Sacred Treasure has been treated as between the 2nd class and the 3rd class of the Order of the Rising Sun and the Order of the Precious Crown.

The order is conferred by the Emperor of Japan in person on Culture Day (November 3) each year. It is considered equivalent to the highest rank (Grand Cordon) of the Order of the Rising Sun, the Order of the Sacred Treasure, and the Order of the Precious Crown. The only orders that Japanese emperors bestow on recipients by their own hands are the Collar of the Supreme Order of the Chrysanthemum, the Grand Cordon of each order, and the Order of Culture. The badge of the order, which is in gold with white enamel, is in the form of a Tachibana orange blossom; the central disc bears three crescent-shaped jades ('' magatama''). The badge is suspended on a gold and enamel wreath of mandarin or ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Medal Of Honour With Purple Ribbon
A medal or medallion is a small portable artistic object, a thin disc, normally of metal, carrying a design, usually on both sides. They typically have a commemorative purpose of some kind, and many are presented as awards. They may be intended to be worn, suspended from clothing or jewellery in some way, although this has not always been the case. They may be struck like a coin by dies or die-cast in a mould. A medal may be awarded to a person or organisation as a form of recognition for sporting, military, scientific, cultural, academic, or various other achievements. Military awards and decorations are more precise terms for certain types of state decoration. Medals may also be created for sale to commemorate particular individuals or events, or as works of artistic expression in their own right. In the past, medals commissioned for an individual, typically with their portrait, were often used as a form of diplomatic or personal gift, with no sense of being an award for ...

Pneumonia
Pneumonia is an inflammatory condition of the lung primarily affecting the small air sacs known as alveoli. Symptoms typically include some combination of productive or dry cough, chest pain, fever, and difficulty breathing. The severity of the condition is variable. Pneumonia is usually caused by infection with viruses or bacteria, and less commonly by other microorganisms. Identifying the responsible pathogen can be difficult. Diagnosis is often based on symptoms and physical examination. Chest X-rays, blood tests, and culture of the sputum may help confirm the diagnosis. The disease may be classified by where it was acquired, such as community- or hospital-acquired or healthcare-associated pneumonia. Risk factors for pneumonia include cystic fibrosis, chronic obstructive pulmonary disease (COPD), sickle cell disease, asthma, diabetes, heart failure, a history of smoking, a poor ability to cough (such as following a stroke), and a weak immune system.

Video Tape Recorder
A video tape recorder (VTR) is a tape recorder designed to record and playback video and audio material from magnetic tape. The early VTRs were open-reel devices that record on individual reels of 2-inch-wide (5.08 cm) tape. They were used in television studios, serving as a replacement for motion picture film stock and making recording for television applications cheaper and quicker. Beginning in 1963, videotape machines made instant replay during televised sporting events possible. Improved formats, in which the tape was contained inside a videocassette, were introduced around 1969; the machines which play them are called videocassette recorders. An agreement by Japanese manufacturers on a common standard recording format, which allowed cassettes recorded on one manufacturer's machine to play on another's, made a consumer market possible; and the first consumer videocassette recorder, which used the U-matic format, was introduced by Sony in 1971.

History Of Television
The concept of television was the work of many individuals in the late 19th and early 20th centuries. The first practical transmissions of moving images over a radio system used mechanical rotating perforated disks to scan a scene into a time-varying signal that could be reconstructed at a receiver back into an approximation of the original image. Development of television was interrupted by the Second World War. After the end of the war, all-electronic methods of scanning and displaying images became standard. Several different standards for addition of color to transmitted images were developed with different regions using technically incompatible signal standards. Television broadcasting expanded rapidly after World War II, becoming an important mass media, mass medium for advertising, propaganda, and entertainment. Television broadcasts can be distributed over the air by VHF and UHF radio signals from terrestrial transmitting stations, by microwave signals from Earth orbi ...
