As a result, the temperature of armature 8 rises to lower its magnetic characteristic so that the magnetic force of permanent magnet 9 can overcome. Therefore, the armature 8 moves away from the side face 1d to adhere to a flange portion 6c, whereas the diameter of spring 7 is returned to its original position to abut its outer diameter surface against the inner surface of shell 6b. In this manner, an operating safety can be ensured without the chance of load being transmitted to the side of pulley 1 or the engine at the time of breakdown.

Filed: 1988-08-26
Abstract: PURPOSE:To improve the safety of a circuit economically and reasonably by suppressing an overvoltage generated in a switching element for a period, during which a voltage vibration system has a transient apex, in an inverter apparatus equipped with said voltage vibration system including an inductor an a capacitor. CONSTITUTION:Because an oscillation frequency is high directly after power closing, the ON period of a transistor Q1 is short and the energy stored in a resonance inductor L1 is reduced so that the peak value of a resonance voltage for the OFF period falls. After that, with the lapse of time, the reference voltage Vk of a comparator CP1 becomes gradually higher and the oscillation frequency of an inverter circuit 1 lowers gradually from a preheating frequency to shift to a lighting-up time frequency. Said change of frequency is smoothly conducted according to the time constant of a capacitor C5 and a resistance R10. Thus, said reference voltage Vk is set arbitrarily so that the ON period of said transistor Q1 can be changed over a wide range and a starting frequency and said preheating and lighting-up time frequencies can be set arbitrarily.
