摘要： The drive part for converting the revolution movement to the wobble movement is composed of the shaft for transmitting the drive force from outside, the swash plate rotated by the shaft and the wobble plate for converting the revolution movement of the swash plate to the wobble movement. Plural pistons are reciprocated in responsive to the wobble movement of the wobble plate. The crank room containing the swash plate, the wobble plate and the piston is separated into the fuel room and the drive room by the bellows. The bearings for transmitting the drive force between the shaft in the drive room and the swash plate, and the bearing for transmitting the drive force between the swash plate and the wobble plate are placed inside the drive room in order to lubricate the bearings. By arranging plural pistons inside the fuel room, the fuel is forced to be taken in and discharged by the reciprocate movement of the individual pistons.

摘要： A measurement range is divided into a plurality of sections, a binary coded signal is generated at each division point, small section signals are generated at a predetermined interval between the binary coded signals, the binary coded signals are weighted by angles, and the small section signals are added or subtracted to or from the weighted signal to interpolate between two binary coded signals. Since the increment signals generated between the adjacent absolute signals is used as an interpolation signal between the absolute signals, the measurement accuracy is enhanced without increasing the number of elements for generating the absolute signals. The measured angle can be accurately read by adding or subtracting the increment signals to and from the weighted signal of the absolute signal.

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.
