Filed: 1988-05-30
Abstract: PURPOSE:To protect a motor from burning, by providing a electronic circuit for detecting current flowing through a compressor motor and obtaining a DC voltage proportional to the variation of the motor current then producing a time delay and judging overcurrent thus interrupting a solenoid switch. CONSTITUTION:Voltage to be induced in current transformers CT1, CT2 arranged at a current detecting section 11 increases as the motor current increases, and the voltage is rectified at a DC converting section 12 and applied onto a capacitor C1 at a maximum value detecting section 13 thus maintaining the peak value. The peak voltage E1 held in the capacitor C1 is time delayed at a time delay producing section 14, then a capacitor C2 is charged with the time delayed peak voltage E1. When the charged voltage E2 of the capacitor C2 exceeds over a reference voltage E3 at an overcurrent judging section 15, output from a comparator IC1 is turned ON. Consequently, a relay contact 16' is turned OFF to interrupt power supply to the drive coil L1 of a solenoid switch 1, and normal close contacts S11, S12, S13 are turned OFF to stop operation of a compressor motor 3 thus protecting the motor from burning due to overcurrent.

Title: Semiconductor memory system
Inventor: ISHIKAWA YASUYO
IPC: G06F1/30
Filed: 1982-07-30
Abstract: PURPOSE:To prevent data destruction with a low cost, by detecting that the system power supply voltage drops down to the lower limit of the working assurance voltage of a TTL circuit and cutting off the power supply voltage to switch it to a battery power supply. CONSTITUTION:When the system power supply voltage VCC is within the working assurance voltage, a voltage detecting circuit 2 turns on a transistor TRQ1 and a relay 3. Thus a TTL decoder 1 has steady actuation and at the same time produces a chip selection signal -CSi in accordance with the voltage VCC. When the system power supply is cut off and drops down to the reference voltage Vr, the circuit 2 turns off both the TRQ1 and relay 3. Then the output level of the decoder 1 drops down to the battery voltage in response to the fall of the voltage VCC passed through a diode D2. Thus the selection signal -CS equivalent to a retention mode is produced. In this case, the voltage Vr is approximately set at the lower limit 4.75V of the working assurance voltage of a TTL circuit.
