Nobutoshi Kihara
Nobutoshi Kihara (木原 信敏 ''Kihara Nobutoshi'', 14 October 1926 – 13 February 2011) was an engineer at Sony, best known for his work on the original Walkman cassette-tape player in the 1970s and was commonly called ''Mr. Walkman'' in the press. Born in Tokyo, Kihara attended Waseda University, then joined Sony's predecessor, Tokyo Telecommunications Engineering Corporation in 1947 as a new university graduate. He retired from Sony in 2006. While at Sony, he worked on Japan's first magnetic tape recorders, portable tape recorders, music stereo systems, Betamax video, digital cameras, a compact cassette magazine-type recorder and Japan's first transistor radio. In 1964, a team led by Kihara developed the CV-2000, the world's first VTR intended for home usage. He also was instrumental in creating cassette versions of the VTR (Video Tape Recorder),established the basis for the U-matic system. In 1981, was involved in the development of the Mavica digital still camera, wh ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Engineer
Engineers, as practitioners of engineering, are professionals who Invention, invent, design, build, maintain and test machines, complex systems, structures, gadgets and materials. They aim to fulfill functional objectives and requirements while considering the limitations imposed by practicality, regulation, safety and cost. "Science is knowledge based on our observed facts and tested truths arranged in an orderly system that can be validated and communicated to other people. Engineering is the creative application of scientific principles used to plan, build, direct, guide, manage, or work on systems to maintain and improve our daily lives." The word ''engineer'' (Latin , the origin of the Ir. in the title of engineer in countries like Belgium, The Netherlands, and Indonesia) is derived from the Latin words ("to contrive, devise") and ("cleverness"). The foundational qualifications of a licensed professional engineer typically include a four-year Bachelor of Engineering, bache ...

CV-2000
CV-2000 was one of the world's first home video tape recorders (VTR), introduced by Sony in August 1965. The 'CV' in the model name stood for . This was Sony's domestic format throughout the 1960s. It was the first fully transistorized VCR. The CV-2000 was developed by Sony engineer Nobutoshi Kihara. On its release, the CV-2000D machine was listed for US$695——while a portable version in a more durable case, the CV-2000, was listed for $730—. It used video tape in a reel-to-reel format, meaning the tape had to be manually threaded around the helical scan video head drum. The CV-2000 was one-tenth the weight and price of other analog video recording products of its era. It recorded television programs in black and white using the skip field process, which produced a maximum 200-lines resolution. The tape moved at a speed of 7.5 inches per second. Two different reels were marketed: A reel of video tape listed for about US$22——had 30-minute playtime, and video-tape ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

1926 Births
In Turkey, the year technically contained only 352 days. As Friday, December 18, 1926 ''(Julian Calendar)'' was followed by Saturday, January 1, 1927 '' (Gregorian Calendar)''. 13 days were dropped to make the switch. Turkey thus became the last country to officially adopt the Gregorian Calendar, which ended the 344-year calendrical switch around the world that took place in October, 1582 by virtue of the Papal Bull made by Pope Gregory XIII.

Mavica
Mavica (''Magnetic Video Camera'') is a discontinued brand of Sony cameras which use removable disks as the main recording medium. On August 25, 1981, Sony unveiled a prototype of the Sony Mavica as the world's first electronic still video camera. As with all Mavica cameras until the early 1990s (including later models sold commercially) this first model was not digital. Its CCD sensor produced an analog video signal in the NTSC format at a resolution of pixels. Mavipak 2.0" disks (later adopted industry-wide as the Video Floppy and labelled "VF") were used to write 50 still frames onto tracks on disk. The pictures could be shown on a television screen, using a "special playback viewer unit" plugged into the television set. During the late 1990s and early 2000s, Sony reused the Mavica name for a number of digital (rather than analog) cameras that used standard 3.5" floppy disk or 8 cm CD-R media for storage. Original analog Mavica models The initial prototype demonstrated ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
U-matic
U-matic, also known as -inch Type E Helical Scan or SMPTE E, is an analog recording videocassette format developed by Sony. First shown as a prototype in October 1969 and introduced commercially in September 1971, it was among the earliest video formats to house videotape inside a cassette, replacing the reel-to-reel systems common at the time. The format uses tape, earning it the nickname "three-quarter-inch" or simply "three-quarter," in contrast to larger open-reel formats like Type C videotape and quadruplex videotape. The name ''U-matic'' refers to the U-shaped tape path as it threads around the video drum. Unlike most cassette formats, U-matic's supply and take-up reels rotate in opposite directions during playback, fast-forward, and rewind—one clockwise, the other counterclockwise. Each cassette has an internal locking mechanism that secures the tape hubs during transport, and a spring-loaded door that protects the tape; this door automatically opens when the casse ...

Transistor Radio
A transistor radio is a small portable radio receiver that uses transistor-based circuitry. Previous portable radios used vacuum tubes, which were bulky, fragile, had a limited lifetime, consumed excessive power and required large heavy batteries. Following the History of the transistor, invention of the transistor in 1947—a semiconductor device that amplifies and acts as an electronic switch, which revolutionized the field of consumer electronics by introducing small but powerful, convenient hand-held devices—the Regency TR-1 was released in 1954 becoming the first commercial transistor radio. The mass-market success of the smaller and cheaper Sony TR-63, released in 1957, led to the transistor radio becoming the most popular electronic communication device of the 1960s and 1970s. Billions had been manufactured by about 2012. The pocket size of transistor radios sparked a change in popular music listening habits, allowing people to listen to music and other broadcasts o ...

Digital Camera
A digital camera, also called a digicam, is a camera that captures photographs in Digital data storage, digital memory. Most cameras produced today are digital, largely replacing those that capture images on photographic film or film stock. Digital cameras are now widely incorporated into mobile devices like smartphones with the same or more capabilities and features of dedicated cameras. High-end, high-definition dedicated cameras are still commonly used by professionals and those who desire to take higher-quality photographs. Digital and digital movie cameras share an optical system, typically using a Camera lens, lens with a variable Diaphragm (optics), diaphragm to focus light onto an image pickup device. The diaphragm and Shutter (photography), shutter admit a controlled amount of light to the image, just as with film, but the image pickup device is electronic rather than chemical. However, unlike film cameras, digital cameras can display images on a screen immediately afte ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
