Title: Overvoltage protective circuit
Inventor: FUJIMOTO HIDETOSHI
IPC: H02H3/20
Filed: 1993-02-17
Abstract: PURPOSE:To provide an overvoltage protective circuit for power supply which can be built in an integrated circuit and in which internal loss or supply voltage drop for a circuit to be protected are suppressed. CONSTITUTION:Since a Zener diode D1 is normally turned OFF, an NPN transistor Q2 is turned OFF to bring the output voltage V3 from an operational amplifier OP1 down to ground level and thereby a P-channel FET Q1 is turned ON to feed an integrated circuit 2 with a power supply voltage Vin. When an overvoltage is produced from the power supply, the Zener diode D1 is turned ON to cause turn ON of the transistor Q2 and thereby the polarity of differential voltage between the positive and negative input terminals of the operational amplifier OP1 is inverted. Consequently, the output V3 from the operational amplifier OP1 is brought upto the level of the power supply voltage Vin and thereby the PET Q1 is turned OFF to block application of overvoltage to the integrated circuit 2. Since the diode D1 has low loss and the FET Q1 has low normal voltage drop, the overvoltage protective circuit can be built in the integrated circuit.

IPC: E02B7/00
Filed: 1990-02-08
Abstract: PURPOSE:To perform automatic driving without operating a transport carriage by a driver on board by controlling the forward/backward travel of the carriage based on the rotational amount of a cable reel on which a power cable is wound. CONSTITUTION:Travel distance is measured by detecting the rotational amount of the cable reed 53 on which the power cable 54 is wound. Then, the carriage is stopped once at a position where forward travel distance goes to distance in which it arrives at a position subtracted by preset distance from the distance between a bucket lauduig point measured in the backward travel in preceding carrying and a concrete kneading manufacturing part, and it is stared to move forward by receiving a re-start signal. Also, when a continuous travel signal is received after starting, the carriage can be move forward without stopping transiently. In such a way, it is possible to perform the automatic driving of the transport carriage without driving by the operator on board.
