Tokuhichi Mishima
was a Japanese metallurgist and inventor. He discovered that aluminum restored magnetism to non-magnetic nickel steel. He invented MKM steel, which was an extremely inexpensive magnetic substance that has been used in many applications. It is also closely related to the modern Alnico magnets. He later became a professor at the Tokyo Imperial University. After his death, his remains were buried in the Tama Cemetery in Tokyo.

Tama Cemetery
in Tokyo is the largest municipal cemetery in Japan. It is split between the cities of Fuchu and Koganei within the Tokyo Metropolis. First established in April 1923 as , it was redesignated Tama Cemetery in 1935. It is one of the largest green areas in Tokyo. History Around 1900, Tokyo had five public cemeteries - Aoyama, Somei, Yanaka, Zoshigaya and Kameido. As the population of Tokyo grew, and cemetery space grew scarce, there was a need to build a cemetery outside of the city limits of Tokyo. In 1919, city park manager Kiyoshi Inoshita issued a plan to establish a large park/cemetery to the north, east and west of Tokyo. Tama, to the west of Tokyo, was selected in 1920, with construction started two years later. It was said that the site was chosen because of access to transportation infrastructure, such as the Kōshū Kaidō, Keiō Line, Seibu Tamagawa Line, and Chūō Main Line. The cemetery was opened in 1923. The planned northern and eastern cemeteries are Sodaira an ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Ten Japanese Great Inventors
The system of industrial rights in Japan celebrated 100 years of its existence in 1985. In celebration of the one-hundredth anniversary of the Japanese system of industrial property rights, the Japan Patent Office selected ten great inventors whose contributions were particularly memorable and of historical significance in the industrial development of Japan. Reliefs of these inventors were created and presented in the lobby of the Japan Patent Office to commemorate their achievements and introduce them to Japanese people. The inventors The ten inventors are:{{cite web, url=http://www.ajinomoto.com/features/aji-no-moto/en/column/inventors.html, title=Ten great inventors in Japan, publisher=Ajinomoto Group * Sakichi Toyoda Patent Number 1195, Wooden Weaving Machine Driven by Human Power *Kōkichi Mikimoto Patent Number 2670, Cultured pearl * Jōkichi Takamine Patent Number 4785, Adrenaline *Kikunae Ikeda Patent Number 14805, Sodium Glutamate * Umetaro Suzuki Patent Number 2078 ...

Alnico
Alnico is a family of iron alloys which in addition to iron are composed primarily of aluminium (Al), nickel (Ni), and cobalt (Co), hence the acronym ''al-ni-co''. They also include copper, and sometimes titanium. Alnico alloys are ferromagnetic, and are used to make permanent magnets. Before the development of rare-earth magnets in the 1970s, they were the strongest type of permanent magnet. Other trade names for alloys in this family are: ''Alni, Alcomax, Hycomax, Columax'', and ''Ticonal''. The composition of alnico alloys is typically 8–12% Al, 15–26% Ni, 5–24% Co, up to 6% Cu, up to 1% Ti, and the rest is Fe. The development of alnico began in 1931, when T. Mishima in Japan discovered that an alloy of iron, nickel, and aluminium had a coercivity of , double that of the best magnet steels of the time. Properties Alnico alloys can be magnetised to produce strong magnetic fields and have a high coercivity (resistance to demagnetization), thus making strong permanent magn ...

Tokyo
Tokyo (; ja, 東京, , ), officially the Tokyo Metropolis ( ja, 東京都, label=none, ), is the capital and largest city of Japan. Formerly known as Edo, its metropolitan area () is the most populous in the world, with an estimated 37.468 million residents ; the city proper has a population of 13.99 million people. Located at the head of Tokyo Bay, the prefecture forms part of the Kantō region on the central coast of Honshu, Japan's largest island. Tokyo serves as Japan's economic center and is the seat of both the Japanese government and the Emperor of Japan. Originally a fishing village named Edo, the city became politically prominent in 1603, when it became the seat of the Tokugawa shogunate. By the mid-18th century, Edo was one of the most populous cities in the world with a population of over one million people. Following the Meiji Restoration of 1868, the imperial capital in Kyoto was moved to Edo, which was renamed "Tokyo" (). Tokyo was devastate ...

Nickel
Nickel is a chemical element with symbol Ni and atomic number 28. It is a silvery-white lustrous metal with a slight golden tinge. Nickel is a hard and ductile transition metal. Pure nickel is chemically reactive but large pieces are slow to react with air under standard conditions because a passivation layer of nickel oxide forms on the surface that prevents further corrosion. Even so, pure native nickel is found in Earth's crust only in tiny amounts, usually in ultramafic rocks, and in the interiors of larger nickel–iron meteorites that were not exposed to oxygen when outside Earth's atmosphere. Meteoric nickel is found in combination with iron, a reflection of the origin of those elements as major end products of supernova nucleosynthesis. An iron–nickel mixture is thought to compose Earth's outer and inner cores. Use of nickel (as natural meteoric nickel–iron alloy) has been traced as far back as 3500 BCE. Nickel was first isolated and classified as an e ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Magnet
A magnet is a material or object that produces a magnetic field. This magnetic field is invisible but is responsible for the most notable property of a magnet: a force that pulls on other ferromagnetic materials, such as iron, steel, nickel, cobalt, etc. and attracts or repels other magnets. A permanent magnet is an object made from a material that is magnetized and creates its own persistent magnetic field. An everyday example is a refrigerator magnet used to hold notes on a refrigerator door. Materials that can be magnetized, which are also the ones that are strongly attracted to a magnet, are called ferromagnetic (or ferrimagnetic). These include the elements iron, nickel and cobalt and their alloys, some alloys of rare-earth metals, and some naturally occurring minerals such as lodestone. Although ferromagnetic (and ferrimagnetic) materials are the only ones attracted to a magnet strongly enough to be commonly considered magnetic, all other substances respond weakly to ...
