Question: Passage: A tunnel diode or Esaki diode is a type of semiconductor diode that has negative resistance due to the quantum mechanical effect called tunneling. It was invented in August 1957 by Leo Esaki, Yuriko Kurose, and Takashi Suzuki when they were working at Tokyo Tsushin Kogyo, now known as Sony. In 1973, Esaki received the Nobel Prize in Physics, jointly with Brian Josephson, for discovering the electron tunneling effect used in these diodes. Robert Noyce independently devised the idea of a tunnel diode while working for William Shockley, but was discouraged from pursuing it. Tunnel diodes were first manufactured by Sony in 1957, followed by General Electric and other companies from about 1960, and are still made in low volume today.
 Link Information: In 1958, the company changed its name to "Sony". Answer: 1958

Answer: When did Tokyo Tsushin Kogyo change its name?


Question: Passage: Roberts played youth football for Cessnock before joining APIA Leichhardt in the New South Wales State League. He played at APIA in 1964 and 1965. In 1966, he travelled to England to trial with Football League Division One team Chelsea. After the unsuccessful trial he was signed by Blackburn Rovers in April 1966. Roberts played three times for Blackburn in the 1965–66 season, returning then to APIA where he played the remainder of the 1966 season. He was sent out on loan in August 1967 to Chesterfield in the Football League Fourth Division, where he played 46 matches during the 1967–1968 season. In 1968, he was signed by Bradford City; there he made 44 appearances between 1968 and 1970, and played in the team that won promotion from the Fourth Division to the Third Division in 1969. In early 1971 he transferred to Southend United, and at the end of the 1971–1972 season moved to Northampton Town, staying there for one season and playing 13 times.

Question: Passage: Yet another of Krishnamacharya's pupils, K. Pattabhi Jois, came to the United States in 1975, starting a long-lasting craze in the country for Ashtanga Vinyasa Yoga. A vinyasa is a movement that connects yoga poses together; the result is a continuously flowing sequence that can be learnt and practised as a whole, making yoga into an energetic aerobic exercise. Ashtanga Yoga gave rise to various spinoff styles including Power Yoga in the 1990s, with one form created in 1995 by Beryl Bender Birch and others by Bryan Kest, a student of K. Pattabhi Jois, and Baron Baptiste, trained in the hot style of Bikram Yoga. Bikram Choudhury arrived in the United States in 1971, and by 1974 had created his own style of yoga, with the studios heated to . He was strongly charismatic, had been taught yoga by the bodybuilder B. C. Ghosh, Yogananda's youngest brother, and like Jois saw hatha yoga as a religion. The two men made yoga serious, hard work, with an intensity that demanded a lifestyle arranged around yoga; up to that point, it had been seen as a slow, gentle, feminine form of exercise, and classes had consisted mainly of women. Practice was so hot and sweaty, and required such mobility, that clothing was reduced to a new minimum: men often wore nothing but long shorts, while women wore footless leggings, sports bras, and small tank tops.
