Arai (company)
is a Japanese company that designs and manufactures motorcycle helmets and other helmets for motorsports. The business has roots from the turn of the century involving cap production, followed by military headgear from 1930 onwards, industrial safety helmets after World War II, and finally motorcycle helmets from 1952 onward.The story of Arai: Thinking ahead. Interview with Michio Arai by Laurent Benchana. ''Motorcycle Sport & Leisure'', January 2004, pp.062–067. Accessed 10 January 2020 History Arai's origins can be traced back to the production of kepi-style caps by Yuichiro Arai in 1900. His son, Hirotake Arai (who succeeded his father in 1930), a keen motorcyclist, was approached to create a new design of sun-barrier caps for the growing Imperial Japanese Army, which was later involved in the 1934 invasion of China, the Second Sino-Japanese War, and World War II. After production was stopped during WWII, Hirotake Arai created the Arai Sewing Machine Company, which p ...

Joint Stock Company
A joint-stock company is a business entity in which shares of the company's stock can be bought and sold by shareholders. Each shareholder owns company stock in proportion, evidenced by their shares (certificates of ownership). Shareholders are able to transfer their shares to others without any effects to the continued existence of the company. In modern-day corporate law, the existence of a joint-stock company is often synonymous with incorporation (possession of legal personality separate from shareholders) and limited liability (shareholders are liable for the company's debts only to the value of the money they have invested in the company). Therefore, joint-stock companies are commonly known as corporations or limited companies. Some jurisdictions still provide the possibility of registering joint-stock companies without limited liability. In the United Kingdom and in other countries that have adopted its model of company law, they are known as unlimited companies. In t ...

Occupation Of Japan
Japan was occupied and administered by the victorious Allies of World War II from the 1945 surrender of the Empire of Japan at the end of the war until the Treaty of San Francisco took effect in 1952. The occupation, led by the United States with support from the British Commonwealth and under the supervision of the Far Eastern Commission, involved a total of nearly 1 million Allied soldiers. The occupation was overseen by American General Douglas MacArthur, who was appointed Supreme Commander for the Allied Powers by US President Harry Truman; MacArthur was succeeded as supreme commander by General Matthew Ridgway in 1951. Unlike in the occupation of Germany, the Soviet Union had little to no influence over the occupation of Japan, declining to participate because it did not want to place Soviet troops under MacArthur's direct command. This foreign presence marks the only time in Japan's history that it has been occupied by a foreign power. However, unlike in Germany the Alli ...

Pressure Bag Moulding
Pressure bag moulding is a process for moulding reinforced plastics. This process is related to vacuum bag molding. Procedure A solid female mold is used along with a flexible male mold. The reinforcement is placed inside the female mold with just enough resin to permit the fabric to stick in place (wet lay-up). A measured amount of resin is then liberally brushed indiscriminately into the mold and the mold is then clamped to a machine that includes the male flexible mold. Then, the flexible male membrane is inflated with heated compressed air or possibly steam. The female mold can also be heated. Excess resin is forced out along with trapped air. Due to the lower cost of unskilled labor, this method is used extensively in the production of composite helmets A helmet is a form of protective gear worn to protect the head. More specifically, a helmet complements the skull in protecting the human brain. Ceremonial or symbolic helmets (e.g., a policeman's helmet in the United K ...

Lamination
Lamination is the technique/process of manufacturing a material in multiple layers, so that the composite material achieves improved strength, stability, sound insulation, appearance, or other properties from the use of the differing materials, such as plastic. A laminate is a permanently assembled object created using heat, pressure, welding, or adhesives. Various coating machines, machine presses and calendering equipment are used. Materials There are different lamination processes, depending primarily on the type or types of materials to be laminated. The materials used in laminates can be identical or different, depending on the process and the object to be laminated. Textile Laminated fabric are widely used in different fields of human activity, including medical and military. Woven fabrics (organic and inorganic based) are usually laminated by different chemical polymers to give them useful properties like chemical resistance, dust, grease, windproofness, photolumin ...

Fibre-reinforced Plastic
Fibre-reinforced plastic (FRP; also called fibre-reinforced polymer, or in American English ''fiber'') is a composite material made of a polymer matrix reinforced with fibres. The fibres are usually glass (in fibreglass), carbon (in carbon-fibre-reinforced polymer), aramid, or basalt. Rarely, other fibres such as paper, wood, or asbestos have been used. The polymer is usually an epoxy, vinyl ester, or polyester thermosetting plastic, though phenol formaldehyde resins are still in use. FRPs are commonly used in the aerospace, automotive, marine, and construction industries. They are commonly found in ballistic armour and cylinders for self-contained breathing apparatuses. Process definition A polymer is generally manufactured by step-growth polymerization or addition polymerization. When combined with various agents to enhance or in any way alter the material properties of polymers, the result is referred to as a plastic. Composite plastics refers to those types of plastic ...

Continental Europe
Continental Europe or mainland Europe is the contiguous continent of Europe, excluding its surrounding islands. It can also be referred to ambiguously as the European continent, – which can conversely mean the whole of Europe – and, by some, simply as the Continent. When Eurasia is regarded as a single continent, Europe is treated as a subcontinent, and called as European subcontinent. The old notion of Europe as a cultural term was centred on core Europe (''Kerneuropa''), the continental territory of the historical Carolingian Empire, corresponding to modern France, Italy, German-speaking Europe and the Benelux states (historical Austrasia). This historical core of "Carolingian Europe" was consciously invoked in the 1950s as the historical ethno-cultural basis for the prospective European integration (see also Multi-speed Europe). Usage The most common definition of Mainland Europe excludes these continental islands: the Greek Islands, Cyprus, Malta, Sicily, Sa ...

David Aldana
David Aldana (born November 26, 1949) is an American former professional motorcycle racer who specialized in dirt track oval racing and road racing. In the 1970s, he was one of the more colorful racers in the A.M.A. Grand National Championship with his wild riding style and extravagant designs on his riding attire. Aldana competed in nearly every form of motorcycle racing, including competing in the 1970 Trans-AMA motocross series and speedway racing. Born in Santa Ana, California, Aldana became a rookie expert on the AMA Grand National circuit in 1970 riding for BSA. Aldana made a serious challenge for the championship. A crash at the Sacramento Mile with just three races to go dashed his hopes for the title, but along the way he won three nationals and finished third in the series. He won over many fans with his all-or-nothing style. He also gained notoriety from wearing a set of racing leathers he designed that featured an almost entirely black leather suit with a contrasting ...

Daytona 200
The Daytona 200 is an annual motorcycle road racing competition held in early spring at the Daytona International Speedway in Daytona Beach, Florida. The race was founded in 1937 when it was sanctioned by the American Motorcyclist Association (AMA). The original course used the beach itself before moving to a paved closed circuit in 1961. The Daytona 200 reached its zenith of worldwide popularity in the 1970s when the race attracted the largest crowds of any AMA race along with some of the top rated international motorcycle racers. History Dirt track origins The origins of the Daytona 200 began in 1932 when the Southeastern Motorcycle Dealers Association organized a 200-mile dirt track race held on the old Vanderbilt Cup course in Savannah, Georgia. Competitors raced on Class C motorcycles typically used in the AMA Grand National Championship. Following a second Savannah race held in 1933, the 1934 event was moved to the Camp Foster Work Camp located on the St. Johns River nea ...

Japanese Industrial Standards
are the standards used for industrial activities in Japan, coordinated by the Japanese Industrial Standards Committee (JISC) and published by the Japanese Standards Association (JSA). The JISC is composed of many nationwide committees and plays a vital role in standardizing activities across Japan. History In the Meiji era, private enterprises were responsible for making standards, although the Japanese government too had standards and specification documents for procurement purposes for certain articles, such as munitions. These were summarized to form an official standard, the Japanese Engineering Standard, in 1921. During World War II, simplified standards were established to increase matériel output. The present Japanese Standards Association was established in 1946, a year after Japan's defeat in World War II. The Japanese Industrial Standards Committee regulations were promulgated in 1946, and new standards were formed. The Industrial Standardization Law was enacted ...
