Seibu 30000 Series
The is an electric multiple unit (EMU) train type operated by the private railway operator Seibu Railway on commuter services in the Tokyo area of Japan. First introduced in April 2008, a total of six 10-car sets, eighteen 8-car sets, and six 2-car sets were built by Hitachi between 2008 and 2016 to replace older three-door 101 series and 301 series sets. It is nicknamed the . Design Sets are formed as two-, eight-, and ten-car units, consisting of aluminium wide-bodied () long four-door cars with no end gangway doors. Six-car sets were also scheduled to be built by fiscal 2011, but none were ultimately delivered. Fleet , the fleet consists of six ten-car sets, 18 eight-car sets, and six two-car sets, based at Kotesashi, Minami-Iriso, Musashigaoka, and Tamagawa-Josui depots for use on Seibu Shinjuku Line and Seibu Ikebukuro Line workings.

Pantograph (rail)
A pantograph (or "pan" or "panto") is an apparatus mounted on the roof of an electric train, tram or electric bus to collect power through contact with an overhead line. By contrast, battery electric buses and trains are charged at charging stations. The pantograph is a common type of current collector; typically, a single or double wire is used, with the return current running through the rails. The term stems from the resemblance of some styles to the mechanical pantographs used for copying handwriting and drawings. Invention The pantograph, with a low-friction, replaceable graphite contact strip or "shoe" to minimise lateral stress on the contact wire, first appeared in the late 19th century. Early versions include the bow collector, invented in 1889 by Walter Reichel, chief engineer at Siemens & Halske in Germany, and a flat slide-pantograph first used in 1895 by the Baltimore and Ohio Railroad The familiar diamond-shaped roller pantograph was devised and patented b ...

Electric Multiple Units Of Japan
Electricity is the set of physical phenomena associated with the presence and motion of matter that has a property of electric charge. Electricity is related to magnetism, both being part of the phenomenon of electromagnetism, as described by Maxwell's equations. Various common phenomena are related to electricity, including lightning, static electricity, electric heating, electric discharges and many others. The presence of an electric charge, which can be either positive or negative, produces an electric field. The movement of electric charges is an electric current and produces a magnetic field. When a charge is placed in a location with a non-zero electric field, a force will act on it. The magnitude of this force is given by Coulomb's law. If the charge moves, the electric field would be doing work on the electric charge. Thus we can speak of electric potential at a certain point in space, which is equal to the work done by an external agent in carrying a unit of p ...

Doraemon (character)
is a fictional character in the Japanese manga and animated series of the same name created by Fujiko F. Fujio, the pen name of writing team Hiroshi Fujimoto and Motoo Abiko. Doraemon is a male robotic earless cat that travels back in time from the 22nd century to aid a preteen boy named Nobita. An official birth certificate for the character gives him a birth date of 3 September 2112 and lists his city of residency as Kawasaki, Kanagawa, the city where the manga was created. In 2008, Japan's Foreign Ministry appointed Doraemon the country's "anime ambassador". Creation and conception Doraemon was originally conceived by Hiroshi Fujimoto following a series of three events. Firstly, when searching for ideas for a new manga, he wished that a machine existed that would come up with ideas for him. Secondly, he tripped over his daughter's toy. Thirdly, he heard cats fighting in his neighborhood. The name, "Doraemon", can be translated roughly to "stray". Unusually, the name is ...

LED Lighting
An LED lamp or LED light bulb is an electric light that produces light using light-emitting diodes (LEDs). LED lamps are significantly more energy-efficient than equivalent incandescent lamps and can be significantly more efficient than most fluorescent lamps. The most efficient commercially available LED lamps have efficiencies of 200 lumen per watt (Lm/W). Commercial LED lamps have a lifespan many times longer than incandescent lamps. LED lamps require an electronic LED driver circuit to operate from mains power lines, and losses from this circuit means that the efficiency of the lamp is lower than the efficiency of the LED chips it uses. The driver circuit may require special features to be compatible with lamp dimmers intended for use on incandescent lamps. Generally the current waveform contains some amount of distortion, depending on the luminaires’ technology. The LED lamp market is projected to grow from US$75.8 billion in 2020 and increasing to US$160 billion in ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Private Railway
A private railway is a railroad run by a private business entity (usually a corporation but not need be), as opposed to a railroad run by a public sector. Japan In Japan, , commonly simply ''private railway'', refers to a public transit railway owned and operated by private sector, almost always organized as a joint-stock company, or in Japanese: kabushiki gaisha (lit. stock company), but may be any type of private business entity. Although the Japan Railways Group (JR Group) companies are also kabushiki gaishas, they are not classified as private railways because of their unique status as the primary successors of the Japanese National Railways (JNR). Voluntary sector railways (semi-public) are additionally not classified as ''shitetsu'' due to their origins as rural, money-losing JNR lines that have since been transferred to local possession, in spite of their organizational structures being corporatized. Among ''private railways'' in Japan, the categorizes 16 companies as "ma ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Electric Multiple Unit
An electric multiple unit or EMU is a multiple-unit train consisting of self-propelled carriages using electricity as the motive power. An EMU requires no separate locomotive, as electric traction motors are incorporated within one or a number of the carriages. An EMU is usually formed of two or more semi-permanently coupled carriages, but electrically powered single-unit railcars are also generally classed as EMUs. The great majority of EMUs are passenger trains, but versions also exist for carrying mail. EMUs are popular on commuter and suburban rail networks around the world due to their fast acceleration and pollution-free operation. Being quieter than diesel multiple units (DMUs) and locomotive-hauled trains, EMUs can operate later at night and more frequently without disturbing nearby residents. In addition, tunnel design for EMU trains is simpler as no provision is needed for exhausting fumes, although retrofitting existing limited-clearance tunnels to accommodate the ...
