    摘要: In an exhaust gas recirculation system for an internal combustion engine, a flow control valve is disposed within a recirculation pipe and operatively connected to a pneumatically operated servomotor to control the flow quantity of exhaust gases through the recirculation pipe, and an orifice is disposed within the recirculation pipe upstream of the valve to form a space between the valve and the orifice. A pressure regulator serves to modulate negative pressure from an engine intake manifold to the servomotor on a basis of pneumatic pressure applied thereto and pressure in the space. The pneumatic pressure applied to the pressure regulator is electrically controlled to satisfy the following equation.Pd=f(Pv, N)where the character Pd is the pneumatic pressure applied to the pressure regulator, and the characters Pv and N respectively indicate the negative pressure in the intake manifold and the engine speed.

    摘要: A pulse radar system which is designed for installation on a vehicle. A control pulse generating circuit is triggered by the trailing edge of a transmitting pulse to generate a pulse train consisting of 8 time-divided pulses which in turn are supplied to a distributor. Simultaneously, the echo of the transmitted pulse is demodulated and the resulting signal is applied to the distributor so that depending on which one of the 8 divided pulses corresponds to the applied demodulated signal, the distance to the target is displayed on the corresponding indicator.

    摘要: A collision sensing system for vehicles is provided in which a moving core shaft having alternately notched and projecting portions formed thereon or a permanent magnet serving as a moving core and magnetized to create therein alternate north and south poles is disposed to move relative to a stator for providing a magnetic path, whereby when a vehicle comes into collision, the magnetic reluctance of the magnetic path is caused to change rapidly at plural times and a generating winding wound on the stator thus generates the waveform of an output voltage proportional to the rate of the plurality of changes of the magnetic reluctance. This output voltage is compared with a predetermined value to determine, whether a controlled system such as an air bag should be actuated to thereby actuate the controlled system properly.
