Abstract: PURPOSE: A method for detecting a belt disconnection is provided to detect disconnection of the belt in a driving apparatus by using revival power. CONSTITUTION: A parameter value is established by operating a specific initialization. In case of detection of a revival voltage while detecting a direct current, a revival interrupt is generated. In case of detection of the revival interrupt, a specific revival period value is added to a prior revival period. Therefore, a present revival period is renewed. The renewed revival period is compared with a specific decision reference time. In case of the renewed revival period is over the reference time, a belt is decided as being normal. Otherwise, the present revival time is subtracted from the reference time for calculating a non-revival period. In case of not detecting the revival interrupt, belt disconnection is decided according to the non-revival period over the reference time and the present revival time under the reference time.

Abstract: PURPOSE: A removing device for deposit of an exhaust valve stem is provided to prevent foreign material in exhaust gas in a stem unit while eliminating the deposit on the stem unit for expanding life span of a valve and for improving reliability on operation of the valve. CONSTITUTION: In an exhaustion stroke, a stem unit(4) is lowered to open an exhaust valve(3) for discharging exhaust gas while hitting on a rotating blade(11) on an outer circumference of a rotor(10). Therefore, the rotating blade and the rotor are rotated at a high speed while being elevated along the stem unit. By elevation and rotation of the rotor, slots(12) on the rotor eliminates deposit on a surface of the stem unit. Moreover, the exhaust gas is transferred while being dispersed along the outer circumference of the rotor. Therefore, the exhaust gas is prevented from being directly contacted to the stem unit. Thus, the stem unit is not heated. In case of closed state of the exhaust valve by elevation of the stem unit, the exhaust gas is not discharged through an exhaust port(5). Therefore, the rotor and the rotating blade are dropped at a protruded position of a stopper(13).
