摘要： Two cylindrical stator magnetic poles are disposed with a suitable space therebetween, and a plunger is movably disposed within the two stator magnetic poles. A coil is wound around the outer periphery of the two stator magnetic poles, and a current flowing in the coil causes the plunger to advance forward. The current flow is interrupted before the plunger reaches the intermediate position between the two stator magnetic poles, and the plunger thereafter further advances by inertia and strikes a ball. After the ball is struck, the coil is again supplied with a current, and the plunger is in turn supplied with a magnetic force in a retreat direction.

摘要： An excitation device supplies a three-phase AC excitation current to a variable speed generator-motor, and controls the variable speed generator-motor based on a three-phase AC excitation current command value obtained by vector-synthesizing, based on a slip phase from an exciting phase detector, a torque direction excitation current command value from a power adjustment computing device, and a magnetic flux direction excitation current command value from a voltage adjustment computing device by an excitation current adjustment computing device. The variable speed generator-motor includes a power fluctuation suppression circuit that causes the torque direction excitation current command value fixed to a value before switching to follow a torque direction excitation current command target value calculated from an effective power by a predetermined conversion circuit, filter circuit, and limiter circuit during a synchronous operation in an operation control method for operating to switch a variable speed operation method and a synchronous operation method.

摘要： A method of detecting the reference crank angle position in an internal combustion engine at the time of starting the engine, the engine having a crankshaft and a plurality of cylinders and associated with an ignition timing control device having a pulse signal generating mechanism including a rotor and a pair of first and second pulsers angularly spaced around the rotor for detecting passage of reactors disposed on the rotor. According to the method, the internal combustion engine is cranked, and the electric pulse signal generated by the first pulser is counted by a counter by referring to the content of a latch circuit. The counter is reset and enabled to count the electric pulse signal again when the reference crank angle position is not detected until the count of the counter reaches a predetermined count. The predetermined count being equal to a maximum number of electric pulses that can be generated by the first pulser while the rotor makes one revolution. The internal combustion engine is continuously cranked until the reference crank angle position is detected before the count of the counter reaches the predetermined count.
