Title: Overload protection system for metal oxide semiconductor field effect transistor
Inventor: KAGOYA TAKAMI
IPC: H02H7/20
Filed: 1985-09-17
Abstract: PURPOSE:To limit the overcurrent to a proper current corresponding to the temperature of a MOS FET by always supervising a voltage between a drain and a source of the MOS FET and operating an overcurrent protection device when the voltage drop exceeds a predetermined value at current conduction. CONSTITUTION:When an on-signal is outputted from a gate control circuit 11 to a gate G of the MOS FET 12 and a current flows from a drain D to a source S, the voltage drop by the passing current is detected by a voltage detector 21. The on-signal is given also to an on-signal detector 22 to close a switch 23, then the detection voltage from a voltage detector 21 is given to a comparator 24 via the switch 23 and when it is larger than the set value decided by a setting resistor 25, a signal is fed to the gate control circuit 11 and an off-signal is given to the gate G. The overload protection device is operated even with a small current at a high temperature of the MOS FET having a positive resistance temperature coefficient, a large current is allowed at a low temperature so as to contribute to the improvement of the efficiency of the device.

Title: Input and output device controlling system
Inventor: OSADA TAKATOSHI
IPC: G06F13/42
Filed: 1981-12-18
Abstract: PURPOSE:To control an input/output device effectively, by transmitting a control signal until the signal reaches a prescribed number of times at a prescribed time interval, when a CPU can not detect the reception signal within a prescribed  time due to an interference signal, and monitoring a reception signal. CONSTITUTION:An input/output control section 11 of the CPU 1 and input/output devices 2 transmit various control signals, confirming signals and required data via a bus 3. The CPU 1 starts measurement 126, if no confirming signal is returned from the devices 2 to the bus 3 after the CPU 1 transmits the control signal to the devices 2 via the bus 3. When it is detected 121 that this time reaches a prescribed time, the control signal is retransmitted. Thus, the transmission of the control signal and the monitoring of the reception signal are done until the retransmission reaches a prescribed number of times in a prescribed time interval. Then, the reception signal interfered owing to the generation of a temporary interference signal is transmitted and detected normally.

CONSTITUTION:A commercial power source 6 is stopped, and when output voltage from a rectifier circuit 2 is made lower than voltage between the terminals of a storage battery 7, then from the base of a transistor Q2 to a collector, the voltage between the terminals of the storage battery 7 is applied. Accordingly, the transistor Q2 is worked as a diode in the direction from the base to the collector. Then, a current from the storage battery 7 flows to voltage dividing resistors R1, R2 via a resistor RE, and as its result, voltage is applied to the terminal 32 of a timer circuit 31. The voltage is set greater than the charging controlling voltage of the timer circuit 31. Accordingly, even if the power feed is re-started, the timer circuit 31 is not reset, and so timer working is not re-started, and accordingly, the storage battery 7 is not overcharged.
