Tokyo Metro 9000 Series
The is an electric multiple unit (EMU) train type operated by the Tokyo subway operator Tokyo Metro on the Tokyo Metro Namboku Line in Tokyo, Japan, since 1991. Variants , the fleet consists of 23 six-car sets (numbered 01 to 23), all based at Oji depot in Tokyo. Prototype A prototype four-car set was built by Kawasaki Heavy Industries in 1990 (formed of cars 9101-9201-9301-9801) for testing on the Chiyoda Line prior to the opening of the Namboku Line in 1991. 1st batch Full-production four-car sets 02 to 07 were delivered in 1991 ahead of the Namboku Line opening, followed by an additional set in 1992, set 08, to act as a spare. The original four-car sets were reformed as six-car sets coinciding with the opening of the extension of the line from Yotsuya to Komagome on 26 March 1996. This was achieved by renumbering the centre cars (9200 and 9300) of sets 02, 04, 06, and 08 as 9600 and 9700 cars which were inserted into sets 01, 03, 05, and 07. New-build (2nd batch) inte ...

MOSFET
The metal–oxide–semiconductor field-effect transistor (MOSFET, MOS-FET, or MOS FET) is a type of field-effect transistor (FET), most commonly fabricated by the controlled oxidation of silicon. It has an insulated gate, the voltage of which determines the conductivity of the device. This ability to change conductivity with the amount of applied voltage can be used for amplifying or switching electronic signals. A metal-insulator-semiconductor field-effect transistor (MISFET) is a term almost synonymous with MOSFET. Another synonym is IGFET for insulated-gate field-effect transistor. The basic principle of the field-effect transistor was first patented by Julius Edgar Lilienfeld in 1925.Lilienfeld, Julius Edgar (1926-10-08) "Method and apparatus for controlling electric currents" upright=1.6, Two power MOSFETs in V_in_the_''off''_state,_and_can_conduct_a_continuous_current_of_30 surface-mount_packages._Operating_as_switches,_each_of_these_components_can_su ...

Komagome Station
is a railway station in Toshima, Tokyo, Japan, operated by the East Japan Railway Company (JR East) and the Tokyo subway operator Tokyo Metro. Lines Komagome Station is served by the circular Yamanote Line and by the Tokyo Metro Namboku Line subway line. Station layout Chest-height platform edge doors were installed on the Yamanote Line platforms during fiscal 2013.

Yotsuya Station
is a railway station in the Yotsuya district of Shinjuku, Tokyo, Japan, operated jointly by East Japan Railway Company (JR East) and Tokyo Metro. Several parts of the station are also located in the Rokubancho and Kojimachi neighborhoods of Chiyoda ward. Lines Yotsuya Station is served by the JR East Chūō Main Line with both Chūō Line (Rapid) and Chūō-Sōbu Line local services stopping here. It is also served by the Tokyo Metro Marunouchi Line (station number M-12) and Tokyo Metro Namboku Line (station number N-08) subway lines. The station is from the Marunouchi Line terminus at Ikebukuro, and from the Namboku Line terminus at Meguro. All four lines at Yotsuya run north to south; however, the Chūō/Chūō-Sōbu Line and Marunouchi Line are mainly east–west lines, and somewhat counter-intuitively, while northbound Chūō Line trains are bound for Tokyo and southbound trains are bound for Shinjuku, northbound Marunouchi Line trains are bound for Shinjuku and southb ...

Chiyoda Line
The is a subway line owned and operated by Tokyo Metro in Tokyo, Japan. On average, the line carries 1,447,730 passengers daily (2017), the second highest of the Tokyo Metro network, behind the Tozai Line (1,642,378).Tokyo Metro station ridership in 2010 ''Train Media (sourced from Tokyo Metro)'' Retrieved July 23, 2018.

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 ...

Janney Coupler
Janney couplers are a semi-automatic form of railway coupling that allow rail cars and locomotives to be securely linked together without rail workers having to get between the vehicles. They are also known as American, AAR, APT, ARA, MCB, knuckle, Buckeye, tightlock (in the UK), Henricot (in Belgium) or Centre Buffer Couplers. Background Janney couplers were first patented in 1873 by Eli H. Janney (). Andrew Jackson Beard was amongst various inventors that made a multitude of improvements to the knuckle coupler; Beard's patents were granted 23 November 1897, which then sold for approximately $50,000, and granted 16 May 1899. In the UK, several versions of Janney couplers are fitted to a limited number of coaches, multiple units, wagons and locomotives. Janney Type E, Type F Interlock, and Type H tightlock couplings are compatible subtypes, each intended for specific rail car types. Prior to the formation of the Association of American Railroads (AAR) these were known as ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
CS-ATC
Automatic train control (ATC) is a general class of train protection systems for railways that involves a speed control mechanism in response to external inputs. For example, a system could effect an emergency brake application if the driver does not react to a signal at danger. ATC systems tend to integrate various cab signalling technologies and they use more granular deceleration patterns in lieu of the rigid stops encountered with the older automatic train stop (ATS) technology. ATC can also be used with automatic train operation (ATO) and is usually considered to be the safety-critical part of a railway system. Over time, there have been many different safety systems labelled as "automatic train control". The first experimental apparatus was installed on the Henley branch line in January 1906 by the Great Western Railway, although it would now be referred to as an automatic warning system (AWS) because the driver retained full command of braking. The term is especially com ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Regenerative Braking
Regenerative braking is an energy recovery mechanism that slows down a moving vehicle or object by converting its kinetic energy into a form that can be either used immediately or stored until needed. In this mechanism, the electric traction motor uses the vehicle's momentum to recover energy that would otherwise be lost to the brake discs as heat. This method contrasts with conventional braking systems. In those systems, the excess kinetic energy is converted to unwanted and wasted heat due to friction in the brakes, or with rheostatic brakes, where the energy is recovered by using electric motors as generators but is immediately dissipated as heat in resistors. In addition to improving the overall efficiency of the vehicle, regeneration can significantly extend the life of the braking system as the mechanical parts will not wear out quickly. General principle The most common form of regenerative brake involves an electric motor functioning as an electric generator. In elect ...
