Clear View Screen
A clear view screen or clearview screen is a glass disk mounted in a window that rotates to disperse rain, spray, and snow. A clear view screen is typically driven by an electric motor at the center of the disk, and is often heated to prevent condensation or icing. Other common names for it include "clear sight", "spin window" and "rotating windshield wiper". Clear view screens were patented in 1917 by Samuel Augustine de Normanville and Leslie Harcourt Kent as a stand-alone pillar-mounted screen, with later patents for telescope and optics covers, followed by the more familiar ships bridge glass. Clear view screens are also used in locomotives and rail transport, and were unsuccessfully marketed for automobiles. They were initially manufactured by George Kent Ltd, a firm began by Leslie Kent's grandfather, and of which Leslie Kent later was a director. The technology was then acquired by BAE Marine Works to produce clear view screens for military applications. BAE Marines Works w ...

Locomotives
A locomotive or engine is a rail transport vehicle that provides the motive power for a train. If a locomotive is capable of carrying a payload, it is usually rather referred to as a multiple unit, motor coach, railcar or power car; the use of these self-propelled vehicles is increasingly common for passenger trains, but rare for freight (see CargoSprinter). Traditionally, locomotives pulled trains from the front. However, push-pull operation has become common, where the train may have a locomotive (or locomotives) at the front, at the rear, or at each end. Most recently railroads have begun adopting DPU or distributed power. The front may have one or two locomotives followed by a mid-train locomotive that is controlled remotely from the lead unit. __TOC__ Etymology The word ''locomotive'' originates from the Latin 'from a place', ablative of 'place', and the Medieval Latin 'causing motion', and is a shortened form of the term ''locomotive engine'', which was first ...

JNR Class DD51
The is a B-2-B wheel arrangement diesel-hydraulic locomotive type operated in Japan since 1962. 649 locomotives were built between 1962 and 1978 by Kawasaki Sharyo, Hitachi, and Mitsubishi. The class was designed for mainline passenger and freight use with more power than the D51 and a higher maximum speed than the C62 steam locomotive classes. This was achieved by installing two 1,100 hp engines in an 18 metre long centre-cab design, unusual for mainline operation. The V12 DML61 engines were developed from the 6-cylinder inline DMF31 engines used in the Class DD13 locomotives. , 29 locomotives remained in operation. Variations Locos numbered from DD51 501 to 799 and from 1001 to 1186 were equipped to operate in multiple, and locos numbered DD51 800 to 899 and 1801 to 1805 were built without steam generators for train heating. Liveries All locomotives numbered from DD51 2 onwards were finished in the standard diesel livery of orange/red with grey upper surfaces separate ...

Hokkaidō
is Japan's second largest island and comprises the largest and northernmost prefecture, making up its own region. The Tsugaru Strait separates Hokkaidō from Honshu; the two islands are connected by the undersea railway Seikan Tunnel. The largest city on Hokkaidō is its capital, Sapporo, which is also its only ordinance-designated city. Sakhalin lies about 43 kilometers (26 mi) to the north of Hokkaidō, and to the east and northeast are the Kuril Islands, which are administered by Russia, though the four most southerly are claimed by Japan. Hokkaidō was formerly known as ''Ezo'', ''Yezo'', ''Yeso'', or ''Yesso''. Nussbaum, Louis-Frédéric. (2005). "Hokkaidō" in Although there were Japanese settlers who ruled the southern tip of the island since the 16th century, Hokkaido was considered foreign territory that was inhabited by the indigenous people of the island, known as the Ainu people. While geographers such as Mogami Tokunai and Mamiya Rinzō explored the isla ...

Watercraft Components
Any vehicle used in or on water as well as underwater, including boats, ships, hovercraft and submarines, is a watercraft, also known as a water vessel or waterborne vessel. A watercraft usually has a propulsive capability (whether by sail, oar, paddle, or engine) and hence is distinct from a stationary device, such as a Floating dock (jetty), pontoon, that merely Buoyancy, floats. Types Most watercraft may be described as either a ship or a boat. However, numerous items, including surfboards, robot, underwater robots, seaplanes and torpedoes, may be considered neither ships nor boats. Although ships are typically larger than boats, the distinction between those two categories is not one of size per se. *Ships are typically large ocean-going vessels; whereas boats are smaller, and typically travel most often on inland or coastal waters. *A rule of thumb says "a boat can fit on a ship, but a ship can't fit on a boat", and a ship ''usually'' has sufficient size to carry its ...
