A vehicle remote controller that reduces the number of parts. The vehicle remote controller includes a portable device carried by a driver and a transceiver (11) arranged in the vehicle to output a request signal for intercommunicating with the portable device and to output a transponder driving radio wave. The transceiver outputs the request signal to either a first area, which is in a vehicle passenger compartment, or an area outside the vehicle, and has a common antenna (14) for outputting the transponder driving radio wave to a second area, which is in the vehicle passenger compartment.
摘要:
A multistage compressor has a yoke with a cross slider and roller bearings pressed against the sides of the cross slider by spring forces to enable the cross slider to slide smoothly within the yoke. The spring forces are generated by springs disposed between the yoke and a liner plate that urges the roller bearings against the cross slider. By this construction, the yoke and cross slider are not damaged during operation of the compressor even if the dimensions of the members change due to thermal expansion.
摘要:
A controller enabling switching between a smart function and an immobilizer function without using a key cylinder or a slot. The controller includes a verification ECU for transmitting a request signal to a first area and transmitting a transponder drive radio wave to a second area. The portable device transmits an ID code signal in response to the request signal or the transponder drive radio wave. The verification ECU enables the starting of an engine when the ID code transmitted from the portable device matches an ID code of the controller. The verification ECU transmits the drive radio wave when a driver operates a switch in a state in which the starting of the engine is not enabled after the request signal is transmitted.
摘要:
A semiconductor device that is equipped with a semiconductor substrate, a composite metal film, and a detection terminal is provided. The composite metal film is formed on a surface or a back face of the semiconductor substrate, and has a first metal film, and a second metal film that is joined to the first metal film and is different in Seebeck coefficient from the first metal film. The detection terminal can detect a potential difference between the first metal film and the second metal film.
