Abstract: A breakdown precautionary system of a semiconductor equipment includes a semiconductor equipment with a coil heater, at least a voltage/current detector, and an alarm system. The voltage/current detector detects the voltage and current of the coil heater at the same time. An alarm system will send an alarm signal and initiate an interlock safety measure of the semiconductor equipment when the detected current of the coil heater is 0 ampere.

Abstract: A horse-riding simulation device contains a seat, a stand, a support member, a power source, a front-back driving member, and a left-right driving member. The device mainly uses belts as the transmission mechanism. Through a belt, a motor of the power source drives an axle of the front-back driving member to spin. The axle in turn drives another axle of the left-right driving member to spin via another belt. The second axle has an eccentric crank shaft connecting to a place of the stand via a shaft. When the crank shaft is spun, the seat pin-joined to the stand is swung to the left and to the right periodically by the shaft.

Abstract: A horse-riding type exerciser comprises a base, a support structure, a power system, a first spindle structure, a second spindle structure, a rocking means and a seat cushion. The power system can drive the first spindle structure and the second spindle structure for further allowing the multi-angular movement of the rocking means. The rocking means is further attached to the seat cushion. As a result, the multi-angular movement of the rocking means further enables the seat cushion to perform changeful movements.
