Technology Transfer
Technology transfer (TT), also called transfer of technology (TOT), is the process of transferring (disseminating) technology from the person or organization that owns or holds it to another person or organization, in an attempt to transform inventions and scientific outcomes into new products and services that benefit society. Technology transfer is closely related to (and may arguably be considered a subset of) knowledge transfer. A comprehensive definition of technology transfer today includes the notion of collaborative process as it became clear that global challenges could be resolved only through the development of global solutions. Knowledge and technology transfer plays a crucial role in connecting innovation stakeholders and moving inventions from creators to public and private users. Intellectual property (IP) is an important instrument of technology transfer, as it establishes an environment conducive to sharing research results and technologies. Analysis in 2003 showe ...

China Railway CRH2
The CRH2 Hexie (simplified Chinese: 和谐号; traditional Chinese: 和諧號; pinyin: Héxié Hào; literally: "Harmony") is one of the high-speed train models in China. The CRH2 is based on the E2-1000 Series Shinkansen design from Japan with the license purchased from a consortium formed of Kawasaki Heavy Industries, Mitsubishi Electric, and Hitachi, and represents the second Shinkansen train model to be exported. In 2004, the Ministry of Railway in China purchased an initial 60 sets of the train from Kawasaki Heavy Industries with a maximum speed of . However, the newer versions of the CRH2 are not related to the E2-1000 Series despite having the same exterior shell. Variants CRH2A On October 20, 2004, the Ministry of Railway in China ordered 60 sets of CRH2A trains from Kawasaki Heavy Industries in Japan. Along with 60 sets of Bombardier's Regina-based CRH1A, and 40 sets of Alstom's Pendolino-based CRH5A, these train sets are consider as first batch of CRH trai ...

Hexie (train)
Hexie (), also known as the CRH series EMU, is an umbrella term for the multiple unit High-speed rail, high-speed and Higher-speed rail, higher-speed trains operated by China Railway under the China Railway High-speed brand. All series of Hexie are based on foreign-developed technology and later manufactured locally in China through technology transfer licenses, with the ultimate goal of China acquiring the know-how and capability to produce high-speed rail trains. The Harmony series does not belong to any single platform, instead encompassing all high-speed trains in China with roots in foreign technology, specifically CRH1, CRH2, CRH3 and CRH5. Although later variants of Hexie such as CRH380A were designed by Chinese companies, they are still classified as CRH due to incorporation of foreign technology. History In 2007, China's Ministry of Railways (China), Ministry of Railways drafted a plan for China's future high-speed network. Bombardier Transportation, Kawasaki Heavy Ind ...

Electronically Controlled Pneumatic Brakes
Electronically controlled pneumatic brakes are a type of modern railway braking system which offer improved performance compared to traditional railway air brakes. Overview Traditional train braking systems use pneumatic valves to control and generate brake applications on the cars along the length of the train. In general, this conventional system consists of a brake pipe that runs the length of the train which supplies air to reservoirs mounted on each of the cars. When the brake pipe and car components are charged with air, the brakes release. When the engineer needs to make a brake application, control valves in the locomotive reduce the brake pipe pressure. As the brake pipe pressure reduces, the service portion on each car diverts air from their reservoirs to their brake cylinders. To release the brakes, the engineer charges the brake pipe. This method of controlling the brakes on freight and passenger cars has remained virtually unchanged since its invention by George Wes ...

Regenerative Brake
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 ...

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 ...

Overhead Lines
An overhead line or overhead wire is an electrical cable that is used to transmit electrical energy to electric locomotives, trolleybuses or trams. It is known variously as: * Overhead catenary * Overhead contact system (OCS) * Overhead equipment (OHE) * Overhead line equipment (OLE or OHLE) * Overhead lines (OHL) * Overhead wiring (OHW) * Traction wire * Trolley wire This article follows the International Union of Railways in using the generic term ''overhead line''. An overhead line consists of one or more wires (or rails, particularly in tunnels) situated over rail tracks, raised to a high electrical potential by connection to feeder stations at regular intervals. The feeder stations are usually fed from a high-voltage electrical grid. Overview Electric trains that collect their current from overhead lines use a device such as a pantograph, bow collector or trolley pole. It presses against the underside of the lowest overhead wire, the contact wire. Current collectors are ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
