Nachi-Fujikoshi
(known also by its trademark Nachi) is a Japanese corporation known for its industrial robots, machining tools and systems and machine components. Nachi-Fujikoshi is listed on the Tokyo Stock Exchange and as of January 2014, comprises 50 companies (22 domestic and 28 overseas). Origin of the Nachi trademark The Nachi brand name comes from "Kumano Nachi Taisha", the Grand Shrine. It expresses strong entrepreneurial will. In 1929, the Emperor Showa made a tour of the Kansai district to inspect industries as part of the encouragement of domestic production, and personally inspected a Fujikoshi hacksaw blade that was on display as an example of an outstanding domestic product at the Osaka Prefectural Office. Overjoyed at the honor of entertaining the Emperor's special attention, Kohki Imura decided to name his product "NACHI" after the name of the latest naval cruiser to be made in Japan, the very same vessel that the Emperor was sailing on for his tour.

Public Company
A public company is a company whose ownership is organized via shares of stock which are intended to be freely traded on a stock exchange or in over-the-counter markets. A public (publicly traded) company can be listed on a stock exchange ( listed company), which facilitates the trade of shares, or not ( unlisted public company). In some jurisdictions, public companies over a certain size must be listed on an exchange. In most cases, public companies are ''private'' enterprises in the ''private'' sector, and "public" emphasizes their reporting and trading on the public markets. Public companies are formed within the legal systems of particular states, and therefore have associations and formal designations which are distinct and separate in the polity in which they reside. In the United States, for example, a public company is usually a type of corporation (though a corporation need not be a public company), in the United Kingdom it is usually a public limited company (plc), ...

Japanese Yen
The is the official currency of Japan. It is the third-most traded currency in the foreign exchange market, after the United States dollar (US$) and the euro. It is also widely used as a third reserve currency after the US dollar and the euro. The New Currency Act of 1871 introduced Japan's modern currency system, with the yen defined as of gold, or of silver, and divided decimally into 100 ''sen'' or 1,000 ''rin''. The yen replaced the previous Tokugawa coinage as well as the various ''hansatsu'' paper currencies issued by feudal ''han'' (fiefs). The Bank of Japan was founded in 1882 and given a monopoly on controlling the money supply. Following World War II, the yen lost much of its prewar value. To stabilize the Japanese economy, the exchange rate of the yen was fixed at ¥360 per US$ as part of the Bretton Woods system. When that system was abandoned in 1971, the yen became undervalued and was allowed to float. The yen had appreciated to a peak of ¥271 per US$ i ...

Roll Forming
Roll forming, also spelled roll-forming or rollforming, is a type of rolling involving the continuous bending of a long strip of sheet metal (typically coiled steel) into a desired cross-section. The strip passes through sets of rolls mounted on consecutive stands, each set performing only an incremental part of the bend, until the desired cross-section (profile) is obtained. Roll forming is ideal for producing constant-profile parts with long lengths and in large quantities. Overview A variety of cross-section profiles can be produced, but each profile requires a carefully crafted set of roll tools. Design of the rolls starts with a ''flower pattern'', which is the sequence of profile cross-sections, one profile for each stand of rolls. The roll contours are then derived from the flower pattern profiles. Because of the high cost of the roll sets, computer simulation is often used to develop or validate the roll designs and optimize the forming process to minimize the number o ...

Broaching (metalworking)
Broaching is a machining process that uses a toothed tool, called a broach, to remove material. There are two main types of broaching: ''linear'' and ''rotary''. In linear broaching, which is the more common process, the broach is run linearly against a surface of the workpiece to produce the cut. Linear broaches are used in a broaching machine, which is also sometimes shortened to ''broach''. In rotary broaching, the broach is rotated and pressed into the workpiece to cut an axisymmetric shape. A rotary broach is used in a lathe or screw machine. In both processes the cut is performed in one pass of the broach, which makes it very efficient. Broaching is used when precision machining is required, especially for odd shapes. Commonly machined surfaces include circular and non-circular holes, splines, keyways, and flat surfaces. Typical workpieces include small to medium-sized castings, forgings, screw machine parts, and stampings. Even though broaches can be expensive, bro ...

Gear Cutting
A gear is a rotating circular machine part having cut teeth or, in the case of a cogwheel or gearwheel, inserted teeth (called ''cogs''), which mesh with another (compatible) toothed part to transmit (convert) torque and speed. The basic principle behind the operation of gears is analogous to the basic principle of levers. A gear may also be known informally as a cog. Geared devices can change the speed, torque, and direction of a power source. Gears of different sizes produce a change in torque, creating a mechanical advantage, through their ''gear ratio'', and thus may be considered a simple machine. The rotational speeds, and the torques, of two meshing gears differ in proportion to their diameters. The teeth on the two meshing gears all have the same shape. Two or more meshing gears, working in a sequence, are called a gear train or a ''transmission''. The gears in a transmission are analogous to the wheels in a crossed, belt pulley system. An advantage of gears is t ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
End Mill
An end mill is a type of milling cutter, a cutting tool used in industrial milling applications. It is distinguished from the drill bit in its application, geometry, and manufacture. While a drill bit can only cut in the axial direction, most milling bits can cut in the radial direction. Not all mills can cut axially; those designed to cut axially are known as end mills. End mills are used in milling applications such as profile milling, tracer milling, face milling, and plunging. Types Several broad categories of end- and face-milling tools exist, such as center-cutting versus non-center-cutting (whether the mill can take plunging cuts); and categorization by number of flutes; by helix angle; by material; and by coating material. Each category may be further divided by specific application and special geometry. A very popular helix angle, especially for general cutting of metal materials, is 30°. For finishing end mills, it is common to see more tight spiral, with helix ang ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Drill
A drill is a tool used for making round holes or driving fasteners. It is fitted with a bit, either a drill or driver chuck. Hand-operated types are dramatically decreasing in popularity and cordless battery-powered ones proliferating due to increased efficiency and ease of use. Drills are commonly used in woodworking, metalworking, construction, machine tool fabrication, construction and utility projects. Specially designed versions are made for miniature applications. History Around 35,000 BC, '' Homo sapiens'' discovered the benefits of the application of rotary tools. This would have rudimentarily consisted of a pointed rock being spun between the hands to bore a hole through another material. This led to the hand drill, a smooth stick, that was sometimes attached to flint point, and was rubbed between the palms. This was used by many ancient civilizations around the world including the Mayans. The earliest perforated artifacts, such as bone, ivory, shells, a ...

Japanese Cruiser Nachi
was the second vessel completed of the four-member of heavy cruisers of the Imperial Japanese Navy (IJN), which were active in World War II. page 81 The other ships of the class were , , and . She was named after a mountain in Wakayama Prefecture. Background The ''Myōkō'' class was approved under the 1922–1929 Fleet Modernization Program as the first heavy cruisers to be built by Japan within the design constraints imposed by the Washington Naval Treaty, and was the first of the "10,000-ton" cruisers built by any nation.Chesneau, '' All the World’s Fighting Ships'', p. 118. Naval architect Vice admiral Yuzuru Hiraga was able to keep the design from becoming dangerously top-heavy in its early years by continually rejecting demands from the Imperial Japanese Navy General Staff for additional equipment to the upper decks. However, during modifications and rebuildings in the 1930s, the final displacement rose to 15,933 tons, well over the treaty limits.Patton, ''Japanese Heav ...

Hacksaw
A hacksaw is a fine-toothed saw, originally and mainly made for cutting metal. The equivalent saw for cutting wood is usually called a bow saw. Most hacksaws are hand saws with a C-shaped walking frame that holds a blade under tension. Such hacksaws have a handle, usually a pistol grip, with pins for attaching a narrow disposable blade. The frames may also be adjustable to accommodate blades of different sizes. A screw or other mechanism is used to put the thin blade under tension. On hacksaws, as with most frame saws, the blade can be mounted with the teeth facing toward or away from the handle, resulting in cutting action on either the push or pull stroke. In normal use, cutting vertically downwards with work held in a bench vise, hacksaw blades are set to be facing forwards. History While saws for cutting metal had been in use for many years, significant improvements in longevity and efficiency were made in the 1880s by Max Flower-Nash. George N. Clemson, a founde ...

Emperor Showa
Emperor , commonly known in English-speaking countries by his personal name , was the 124th emperor of Japan, ruling from 25 December 1926 until his death in 1989. Hirohito and his wife, Empress Kōjun, had two sons and five daughters; he was succeeded by his fifth child and eldest son, Akihito. By 1979, Hirohito was the only monarch in the world with the title "emperor". He was the longest-reigning historical Japanese emperor and one of the longest-reigning monarchs in the world. Hirohito was the head of state under the Meiji Constitution during Japan's imperial expansion, militarization, and involvement in World War II. Japan waged a war across Asia in the 1930s and 40s in the name of Hirohito, who was revered as a god. After Japan's surrender, he was not prosecuted for war crimes, as General Douglas MacArthur thought that an ostensibly cooperative emperor would help establish a peaceful Allied occupation, and help the U.S. achieve their postwar objectives. His role duri ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Kumano Nachi Taisha
is a Shinto shrine and part of the UNESCO-designated World Heritage Sacred Sites and Pilgrimage Routes in the Kii Mountain Range of Japan. The Kumano Kodō route connects it to other sites under the same classification, which are primarily located in Wakayama Prefecture, Japan. The four sites on the route, classified as pilgrimage destinations and World Heritage Sites, are: 1) Nachi Taisha; 2) Hongū Taisha; 3) Hayatama Taisha; 4) Koya-san. Kumano Nachi Taisha is also one of the three sacred Kumano Sanzan shrines: # Kumano Nachi Taisha # Kumano Hongū Taisha # Kumano Hayatama Taisha This classification is based mostly in Japanese history, as pilgrims would travel to all three sites to complete their pilgrimage. Kumano Nachi Taisha is an example of Buddhist and Shinto syncretism ( Shinbutsu shūgō) nestled in the Kii Mountains, near Kii Katsuura, Japan. Cedar forests surround the site.
