History of science and technology in Japan

[22] Toshihide Maskawa and Makoto Kobayashi's 1973 article, "CP Violation in the Renormalizable Theory of Weak Interaction",[22] is the fourth most cited high energy physics paper of all time as of 2010.

With the outbreak of the First World War, imported manufactured goods were cut off, as was the inflow of foreign technology, and, as a consequence, a number of new industries, especially in the heavy and chemical sectors, were set up.

There were enquiries also concerning the implementation of patents for the Shimadzu production method in the US, Britain, Italy, Belgium, Sweden, Canada, Australia and France, attesting to the strong international interest in this technology.

In the same year, Shigeyoshi Matsumae (松前重義 1901–1991) was awarded the Asano Prize by Japan's Association of Electrical Engineering for his ground-breaking contribution to the development of telecommunications technology.

When the post-First World War depression hit the works, however, South Manchuria Railroad Company (SMRC) decided to postpone the opening of Anshan's second blast furnace, and proposed construction of steel mills instead.

In addition, in 1921 the works invited six American scholars and engineers, led by Dr W. R. Appleby, the Head of the Department of Metallurgy at Minnesota University, to research the feasibility of such a project in Manchuria.

I learned here that such great innovations (as Umene's) will be continuously succeeded by various applications.This furnace recovered by-products through a regenerative burning apparatus, invented by Kuroda Taizo (黒田泰造 1883–1961) in 1918, engineer at the Yahata Works, it was a revolutionary energy-saving oven based on an energy-recycling system.

In 1962, this technological heritage would produce one of the most important innovations, the Basic Oxygen Furnace Waste Gas Cooling and Clearing System, invented at Yawata Steel (a successor of the Yahata Works).

Two years later, a laboratory and factory were set up at Yokosuka to produce the Type 36 (1903) radios, and these were quickly installed on every major warship in the Combined Fleet by the time the war started.

[74] Alexander Stepanovich Popov of the Naval Warfare Institute had built and demonstrated a wireless telegraphy set in 1900, and equipment from the firm Telefunken in Germany was adopted by the Imperial Russian Navy.

He developed the technique while experimenting with a Technics SL-1200 turntable, finding that its direct-drive motor would continue to spin at the correct RPM even if the DJ wiggled the record back and forth on the platter.

The world's first high volume capable (initially 12 car maximum) "high-speed train" was Japan's Tōkaidō Shinkansen, which officially opened in October 1964, with construction commencing in April 1959.

Several different successful systems were developed, but all of them included a separate furnace (calciner) with the preheater, thereby improving the decarbonization rate of the raw material and increasing the output of the rotary kiln.

Sasaki attributes the basic invention to break the chipset of a calculator into four parts with ROM (4001), RAM (4002), shift registers (4003) and CPU (4004) to an unnamed woman, a software engineering researcher from Nara Women's College, who was present at the meeting.

[113] In 1969, Busicom asked Intel, a company founded one year earlier in 1968 for the purpose of making solid state random-access memory (RAM), to finalize and manufacture their calculator engine.

Shima was responsible for adding a 10-bit static shift register to make it useful as a printer's buffer and keyboard interface, many improvements in the instruction set, making the RAM organization suitable for a calculator, the memory address information transfer, the key program in an area of performance and program capacity, the functional specification, decimal computer idea, software, desktop calculator logic, real-time I/O control, and data exchange instruction between the accumulator and general purpose register.

It was an early desktop computer that combined a Zilog Z80 CPU, keyboard, CRT display, floppy disk drive and MF-DOS operating system into an integrated unit.

[173][174] The first implementation of Real-time 3D ray tracing was the LINKS-1 Computer Graphics System, built in 1982 at Osaka University's School of Engineering, by professors Ohmura Kouichi, Shirakawa Isao and Kawata Toru with 50 students.

[217] LCD displays incorporating thin film and transistors were demonstrated in 1970 by J. Kishimoto from Canon[218] and Katsumi Yamamura from Suwa Seikosha (Seiko),[219] and further developed by Sharp Corporation in 1976.

This led directly to the light sources in fiber-optic communication, laser printers, barcode readers, and optical disc drives, technologies that were commercialized by Japanese entrepreneurs.

[245] Nakamura invented it with Isamu Akasaki and Hiroshi Amano, for which the three of them were awarded the 2014 Nobel Prize in Physics, stating that it "enabled bright and energy-saving white light sources", for applications such as LED lamps.

[300] Yamaha's engineers began adapting Chowning's algorithm for use in a commercial digital synthesizer, adding improvements such as the "key scaling" method to avoid the introduction of distortion that normally occurred in analog systems during frequency modulation.

[301] In the 1970s, Yamaha were granted a number of patents, under the company's former name "Nippon Gakki Seizo Kabushiki Kaisha", evolving Chowning's early work on FM synthesis technology.

[310] The swingy funk element present throughout the Japanese synthpop album Yellow Magic Orchestra (1978) was expressed by Hideki Matsutake programming through subtle variations of the MC-8's input.

[326] Its combination of programmability and familiar preset rhythms made it popular from the late 1970s to the early 1980s, widely adopted by artists such as Blondie, Phil Collins, Ultravox,[279] Underworld, Fatboy Slim, BT, Gary Numan, 808 State, Peter Gabriel, Hall & Oates, Jimmy Edgar, Genesis, Überzone, Bryan Ferry, Men Without Hats, John Foxx and OMD.

[338] In 1980, Roland Corporation introduced the Digital Control Bus (DCB) communications protocol, using the DIN sync interface to synchronize different electronic musical instruments.

[270] DIN sync was introduced by Roland Corporation for the synchronization of music sequencers, drum machines, arpeggiators and similar devices, as part of the Digital Control Bus protocol.

[345][346] The first PCM digital sampler was Toshiba's LMD-649,[347] created in 1981 by engineer Kenji Murata for Japanese electronic music band Yellow Magic Orchestra, who used it for extensive sampling and looping in their 1981 album Technodelic.

Since commercial operation began in 1974, the hearth productivity has been doubled, and several other improvements have been made, including higher-grade matte smelting and the treatment of various secondary materials.

[378] In 1981, Hideo Kodama of Nagoya Municipal Industrial Research Institute invented two additive methods for fabricating three-dimensional plastic models with photo-hardening thermoset polymer, where the UV exposure area is controlled by a mask pattern or a scanning fiber transmitter.
