摘要： A load driving circuit in which an emergency switch for forced stoppage and a service switch for controlling current are connected in series with a load power-feeding circuit. An emergency switch (SWA) and a service switch (SWB) are connected in series with the load power-feeding circuit and the switch (SWB) is periodically turned off for a short time in accordance with the control signal (X) of a service switch control circuit (30). The turn-off state of the switch (SWB) is monitored through the output signal (AC) of a monitoring circuit (40).

摘要： A fail-safe timer circuit which does not generate such an erroneous output that shortens delay time when a fault occurs and an on-delay circuit. The timer circuit comprises an oscillator circuit (11) which generates a timer output from the cathode terminal of a PUT prescribed period after an input signal (VIN) is received and a monitoring circuit (12) which monitors the operation of the oscillator circuit (11). The on-delay circuit comprises a latch (13) which has a first terminal (a) for receiving the input signal (VIN) and a second terminal (b) for receiving an output signal (VO) that the monitoring circuit produces only when it is confirmed that the oscillator circuit (11) is normal by detecting a fall of a cathode terminal voltage of the circuit (11). The latch generates an output signal only when both the input signals are higher in level than the power supply potential, and maintains the state.

摘要： An on-delay circuit using a fail-safe electronic circuit. An input signal higher than a power source potential is inputted to a PUT oscillation circuit. A pulse signal generated with a predetermined time constant is once converted to a level within the range of the power source potential by a level conversion circuit. This signal is inverted and differentiated at its leading edge. The input signal of the PUT oscillation circuit is applied to one input terminal of a fail-safe two-input window comparator and the differential signal is inputted to the other input terminal for self-retention. An output of a logic value 1 is generated from the window comparator with a predetermined delay time. Accordingly, there is provided a fail-safe on-delay circuit the delay time of which is not reduced due to breakdown of a circuit constituent element.
