摘要： A fuel feed control device for an internal combustion engine comprising an electromagnetic valve for controlling the fuel quantity to be fed to the internal combustion engine according to the opening duration of the valve, in which the valve is adapted to be energized to be held in its open state with a holding current, the holding current being large enough to hold the valve in its open state after the valve has been once rendered open but not enough to render the valve open from its closed state and having been applied to the valve before the valve is rendered open from its closed state, and energized to be rendered open from its closed state with a valve opening current along with the holding current, the valve opening current being applied to the valve for a pregiven duration so as to additionally co-operate with the holding current, and, further, when the valve is rendered closed from its open state, the valve is energized with a control current, for a desired duration from the instant when the holding current is cut off, so as to produce backward magnetic flux to cancel the forward magnetic flux induced at the instant when the holding current is cut off, whereby the control device may be improved in the responsiveness in the opening and closing operation of the injection valve.

摘要： A magnetic rotary sensor has a rotary drum carrying thereon magnetically recorded codes representative of discrete positions obtained by dividing one rotation of the drum into a predetermined number of positions. Further, an interval between the adjacent discrete positions identified by the codes is interpolated by interpolation signals generated on the basis of a sine wave signal and a cosine wave signal, which are so produced by magnetic signals additionally recorded on the drum that the periods thereof correspond to the interval. Accordingly, a magnetic rotary sensor can be realized, which is capable of identifying the rotational positions of a rotating body with high resolution without increasing the rotary drum in size.

摘要： This invention relates to an automatic stopping device for stopping a diesel engine through cutting off the fuel supply to the latter upon detect of an accidental reversing of the diesel engine. The reversing of automobile diesel engines is rather easy to occur. In the event of an accidental reversing of the diesel engine, it is necessary to stop the engine immediately, for otherwise the engine may be damaged seriously. According to the invention, the reversing of the diesel engine is detected through the detection of change of phase relation between two phases of output voltage derived from a multi-phase alternator connected to the engine and for charging up the batteries, the change of phase relation occuring when the engine is accidentally reversed. More specifically, the device includes a delay-type flip flop having a data input terminal for receiving the output voltage of one of the phases of the alternator and a clock input terminal adapted to receive the output voltage of another phase, such that an output voltage of a high voltage and low voltage are generated at the output terminal of the flip-flop when the engine is running in the forward and backward direction. The device further includes an engine stopping actuator adapted to stop the diesel engine upon receipt of the low level signal.
