aThe heat pump circuit is a “sealed circuit” which means closed, it is auto lubricated and its operative life can be compared to that of an air conditioner of a refrigerator and with no need of particular maintenance works. 热泵电路是结束的手段,它是汽车被润滑的“被密封的电路”,并且它有效...
aThese tests shall be designed such that eac h circuit element within the microcircuit is stressed by an applied voltage which appr oaches or exceeds the breakdown voltage of the circuit element under test. 这些测试将被设计这样eac h环道元在微型电路之内由appr oaches或超出环道元击穿电压在测试之...
Wind energy facility with a completely closed or at least partially closed cooling circuit, with which the heat to be dissipated from the cooling circuit is dissipated by the tower or the nacelle of the wind energy facility.アロイスヴォベン...
During the 2008 Olympics, the final circuit of the Urban Road Cycling Course concluded at Badaling. Built at a strategic pass north of Beijing, the Ming Dynasty-era Badaling walls provide some the best views of the Wall, since it sits high on a mountain pass and gives excellent visibility f...

An adjustable activation means is used to set the times when these modes are employed. The lock can be closed at any time, irrespective of the operating mechanism mode. The activation means is an electronic timer (8) located in the same electric circuit as the lock and its operating ...
The computational efficiency of quantum mechanics can be characterized in terms of the qubit circuit model, which is defined by a few simple properties: each computational gate is a reversible transformation in a connected matrix group; single wires carry quantum bits, i.e. states of a three-dim...
An optoisolator is an electronic device that can be used to pass information between a diode without passing an electrical current. Because there is no need to directly pass voltage or current between the inputs and outputs in an optoisolator circuit, these components can be used to provide el...
