    摘要： The earth leakage breaker of the invention includes a first comparator; a second comparator connected to the first comparator; a third comparator having a threshold higher than the threshold of the first comparator for distinguishing a leakage current from the grounding current caused by a lightning surge or by the heavy ground fault; a monostable multivibrator triggered by the output of the third comparator for forming a time gate of a predetermined period; a counter for detecting a pulse outputted from the first comparator to distinguish whether the grounding current is caused by the lightning surge or by the heavy ground fault; and a trip signal generator circuit for outputting a trip signal in the case of leakage and heavy ground fault. The earth leakage breaker facilitates avoiding unnecessary breaking of the impulsive grounding current caused by the lightning surge.

    摘要： An electric power steering drive system provided with a motor with its torque pulsation reduced, and a controller characterized by excellent manufacturability. The stator core of a motor is composed of an annular back core and a plurality of teeth created separately from the back core and secured on the inner periphery of the back core. An 8-pole/9-slot, 10-pole/9-slot or 10-pole/12-slot relationship is found between the number of the magnets of a rotor (number of poles) and the number of slots. The diameter of the stator coil is 1.0 mm or more. A motor controller comprises a power module, a conductor module and a control module. The terminal of the power module and the bus bar of the conductor module are connected by welding, whereas the terminal of the power module and terminal of the control module are connected by soldering.

    摘要： An ignition timing control system for an engine provides a counter-measure for an abnormal condition of a signal. The ignition timing control system has a first signal generator for generating a first signal at intervals of a predetermined crank angle while an engine is rotated n times (n is an arbitrary positive number), this first signal including a marked signal designating a particular cylinder each time the engine is rotated n times; a second signal generator for generating a second signal having pulses in a number equal to that of all cylinders of the engine at intervals of substantially an equal crank angle in synchronism with the first signal, this second signal including a signal of a form which is distinguishable from other second signal and which occurs in synchronism with the marked signal; a unit for producing an ignition signal in response to the first signal; a distributor for receiving the ignition signal and distributing the ignition signal in response to the marked signal of the first signal to each cylinder in a predetermined ignition order; a unit for detecting an abnormal condition of the first signal; and a unit for distributing the ignition signal to each cylinder in a predetermined ignition order in response to the signal synchronized with the marked signal of the second signal in place of the marked signal when the abnormal condition of the first signal is detected.
