摘要： A collector voltage of a power management semiconductor device is detected by a first comparator, and when the detected collector voltage exceeds a first reference voltage, the first comparator outputs a first detection signal. Furthermore, a gate voltage of the power management semiconductor device is detected by a second comparator, and when the detected gate voltage exceeds a second reference voltage, the second comparator outputs a second detection signal. The second reference voltage is a minimum gate voltage for feeding a rated power to the power management semiconductor device or over, and less than a line power voltage of a drive circuit of the power management semiconductor device. When both the first detection signal and second detection signal are being outputted, the gate voltage is reduced by a gate voltage reduction means so as to protect the power management semiconductor device from overcurrent and overvoltage.

摘要： A liquid drain (2) includes a drain body (20). The drain body defines a float chamber (30) that is adapted to store a liquid. A liquid level adjusting mechanism serves to adjust the liquid level within the float chamber and includes a float (40; 240; 340; 440; 540). The float has a float body (42; 242; 342; 442; 542) that is adapted to float on the liquid surface within the float chamber. A damper (43; 46; 243; 343; 443) may inhibit or minimize a shaking phenomenon of the float body due to waving of the liquid within the float chamber.

摘要： Noise caused by a mechanical vibration with a vibrator feeder is reduced in a small flow rate powder supplying device. An adverse effect caused by the noise is reduced and a flow rate accuracy is increased. Its responding characteristic is made fast. A powder hopper, a ultrasonic motor, supplying pipes and tube are supported by a supporting member held by a weighing device provided with a weight sensor. A weight signal of a weight sensor is amplified by an amplifier provided with a low pass filter. It is sampled with an A/D converter and converted into a digital value. A flow rate of powder is calculated by a CPU, a motor driving part is controlled and an amplitude of the ultrasonic motor is adjusted in such a way that a flow rate of the powder may become a target value.
