摘要： An ignition circuit for use in an internal combustion engine comprises a magnet generator mechanically connected to a crank shaft of the engine. A first transistor is turned on and off by an alternating voltage signal from the magnet generator. A power transistor forms a closed circuit in cooperation with a high voltage transformer and a current source. The power transistor is controlled by a control signal from the first transistor so as to form a primary current which is abruptly cut off. The transformer induces a high voltage which is supplied for a spark plug in response to abrupt interception of the primary current. A delay element composed of a resistor and a capacitor is connected to a base of the first transistor. A second transistor which is inserted between the delay element and ground has a base connected to the current source through contacts which are closed depending on operating condition of the engine, such as a temperature of cooling water, opening angle of throttle valve and gear position which thereby provide for a delay in the ignition timing.

摘要： A pressure transducer for automobiles comprises a closed housing, a member for detecting the pressure in the suction pipe of an engine and converting the pressure detected into electric signals, an amplification circuit disposed in the closed housing, and an air passage. The air passage communicates with the atmosphere, but prevents water from penetrating therethrough into the closed housing. The air passage comprises an air hole formed in a member defining the closed housing about terminals provided for leading the electric signals out of the closed housing.
