1. Rice Cooker As early as the 1950s, Japanese Ibuka Dai (who was also one of the founders of Sony) invented the world's first rice cooker based on the original heating pot. But this rice cooker is not easy to use. It is actually just a pot with an electric heating device. ?In 1956, Toshiba introduced a mass-produced rice cooker with a built-in timer function to the market. Since then, rice cookers have gradually become popular as a universal rice cooking tool. 2. Modern instant noodles, which have become instant noodles, were invented by Momofuku Ando, ??a Chinese-Japanese born in Taiwan, China in 1910, in Ikeda City, Osaka Prefecture, and later obtained the patent in 1960. ?After Momofuku Ando invented instant noodles, he founded Nissin Food Company to sell "Chicken Ramen" (Nissin Ramen). The initial price was 35 yen, but imitation products appeared immediately, leading to price-cutting competition. 3. Shinkansen? The Shinkansen is a high-speed rail system that connects the entire country of Japan. On October 1, 1964, Japan's first Tokaido Shinkansen opened, connecting Tokyo, Nagoya and Osaka, connecting Japan's three major metropolitan areas. This line is also the first high-speed railway system in the world to be put into commercial operation. 4. Automatic gates? Automatic gates, which are indispensable for public transportation systems such as subways and light rails, were invented by Japan's Omron in 1967. 5. Karaoke Karaoke first originated in Japan. Due to Japanese customs, if a man goes home too early, his neighbors will look down on him. Therefore, many Japanese men gather together after get off work and go home very late. Karaoke, this novel pastime was born. ?Karaoke originally means "unaccompanied band" in Japanese. In the 1960s, Daisuke Inoue invented the accompaniment track and portable microphone when he was a drummer in a salon band in Nishinomiya City, Hyogo Prefecture, Japan when he was young. 6. DVD On December 16, 1994, Sony and Philips took the lead in releasing the "Format and Technical Specifications of Single-sided Double-Layer 12cm (5.25 inches) High-density Multimedia CD", referred to as Multimedia Disc System. It can be said that this is the first quasi-DVD Technical specifications. ?In January 1995, Sony began to build momentum for DVD and hinted that it would take the lead in the DVD field. This means that the DVD competition is completely open. At the same time, Toshiba vows to compete with Sony. For DVD, September 15, 1995 was a critical day. Toshiba and Sony finally reached an agreement to unify DVD standards. 7. Gastroscopy In 1950, Tatsuro Uji, a doctor at the University of Tokyo Hospital in Japan, successfully invented the prototype of flexible gastroscopy, the intragastric camera. The most clinically advanced gastroscopy currently is capsule endoscopy. ?Gastroscopy uses a slender tube with a diameter of about one centimeter in black plastic wrapped with a light guide fiber. An endoscope is installed at the front end and inserted into the subject's esophagus, stomach and duodenum through the mouth. The light source emits light The strong light can be bent through the light guide fiber, allowing doctors to clearly observe the health status of various parts of the upper gastrointestinal tract from the other end. 8. Dry batteries In early 1887, a Japanese watch engineer named Yai Senzo invented the disposable "Yai-type dry battery", but he did not apply for a patent because he could not afford the patent application fee. ?The Yai-type dry battery was widely used by the Japanese army during the Sino-Japanese War. In this way, the application fee was raised in 1895, but it is still recognized that the Yai-type dry battery is the first practical type of dry battery. 9. Esaki Tunnel Diode In August 1958, Reina Esaki, who was working at Tokyo Communications Industry (now Sony), released the tunnel diode. In 1973, Reina Esaki and Brian Josephson won the Nobel Prize in Physics for their discovery of the quantum tunneling effect in semiconductors. ?The advantages of tunnel diodes are good switching characteristics, fast speed, and high operating frequency; the disadvantage is poor thermal stability. Generally used in some switching circuits or high-frequency oscillation circuits. 10. Blue light-emitting diode Blue light-emitting diode, or blue LED, is a light-emitting diode that emits blue light. Its invention is hailed as "the second lighting revolution after Edison". ?The invention of blue LED has enabled mankind to assemble LEDs that can emit light of the three primary colors, and to use LEDs to produce bright enough white light. The invention of white LED lights has greatly improved human lighting efficiency.
In 2014, Isamu Akasaki, a professor at Nagoya University and Meijo University in Japan, Hiroshi Amano, a professor at Nagoya University, and Shuji Nakamura, a professor at the University of California, USA, won the same year for their "invention of high-brightness blue light-emitting diodes, which brought energy-saving and bright white light sources." Nobel Prize in Physics.
