摘要： An apparatus for controlling angular position of optical axis of a head lamp assembly for a motor vehicle. An actuator is supplied selectively with the atmospheric pressure and a negative pressure available from an intake conduit of an internal combustion engine thereby to produce corresponding mechanical displacements. A detector for detecting the angular position of the optical axis of the head lamp assembly responds to the mechanical displacements of the actuator to change-over successively the contact states of a plurality of paired electric contacts. A command unit for setting the angular position of the optical axis of the head lamp assembly is provided which includes a plurality of paired electric contacts connected in one-to-one correspondence to the paired contacts of the optical axis position detector. A signal for setting the optical axis of the head lamp assembly is produced in dependence on the contact states of the optical axis position detector.

摘要： An electric governor for an internal combustion engine comprises an engine speed sensor, a phase shifter, a twin-T type filter and a multiplier for multiplying outputs of the phase shifter and the twin-T type filter. The twin-T type filter is arranged to vary its gain and phase in response to the difference between the peculiar frequency thereof and the frequency of the speed signal, whereby the multiplied outputs varies its amplitude and polarity in response to the frequency difference. A servo motor which is adapted to control the engine speed control mechanism is connected to the multiplier, so that the engine can be controlled to run at a predetermined speed which corresponds to the peculiar frequency of the twin-T type filter.

摘要： A fuel injection timing control system is provided wherein a fluid actuator having a fluid chamber containing therein a movable wall member and the amount of pressure medium in the fluid chamber are controlled by electromagnetically operated control valve means to cause the actuator to operate an element for controlling the fuel injection timing of a fuel injection pump. In the control system of this invention, a control voltage is produced from at least a speed signal corresponding to the rotational speed of an engine and a fuel injection quantity signal corresponding to the amount of fuel injected into the engine from a fuel injection pump, and this control voltage is compared with a injection timing voltage corresponding to the fuel injection timing of the fuel injection pump to produce a deviation signal which is used to actuate the electromagnetically operated control valve means so as to automatically control the fuel injection timing of the injection pump and thereby to obtain the optimum injection timing that suits the varying operating conditions of the engine.
