Abstract: An apparatus for monitoring an electric or electronic device in operation to detect the discontinuity of its ground conductor and the leakage of current. Two ground conductors (103, 104) are connected in common to an electrical/electronic device (100) at one end and grounded independently at the other end (E1, E2) in such a manner as to form one closed loop (CL) comprising the two ground conductors (103, 104), the electrical/electronic device (100), and ground. A detection circuit (105) judges the ground conductors to be normal when the closed loop (CL) is closed, and judges them to be abnormal when the closed loop (CL) is not closed. Leak detection of a motor (1), etc, is made on the basis of a current level flowing through the ground conductors (5A, 5B) using this disconnection detector.

Abstract: A movable section of a machine is enclosed with fences and a door. A locking device provided on the door is controlled by a movable section control circuit. In the movable section control circuit, an operating switch outputs either a movable section ON signal or a movable section OFF signal. A door switch outputs an ON signal representing that the door is open. A switch means constitutes a self-holding circuit which receives as a reset input signal the AND signal of the movable section OFF signal and a rotation stop signal, and as a triggering signal the OR signal of the ON signal and rotation-presence signal. The switch means supplies a control signal to the locking device. When a sensor fails, the locking device is not unlocked even if the operating switch for driving the movable section is closed.

Abstract: By use of shift registers, generated are scanning output signals for synchronously driving a light emitting diode (LD) and a photodetector (PD) both facing each other. Based on the output of the shift register (5) on the light emitting side, whether the scanning output signal is normal or abnormal is judged by addition operated in a scanning output signal checking circuit (9), and at the same time, whether or not the final stage outputs of the shift registers on the light emitting side and photodetecting side coincide with each other is judged by a coincidence detection circuit (10). When the sensor system is abnormal, the sensor output is not generatd (logic value is zero). A simple sensor system having such a fail-safe function can be provided.

Abstract: A circuit for driving a load wherein the breaking mechanism for breaking a main power supply when a failure occurs is a fail-safe one. The circuit can drive an inductive load, saving power. The circuit also is improved in delay of its operation stop. The breaking mechanism is of a contactless one. In a feeding circuit for fedding power to the load, interposed is a means for sensing failure of semiconductor switching elements which perform the ON/OFF control of the power-feed to the load. The breaking mechanism is operated by the output of the failure sensing means. When driving an inductive load, two power supplies for feeding power to the load are interposed in the feeding circuit. Upon generating a signal for commanding the feeding circuit to drive the load, a high voltage is applied to the load by the two power supplies; and after a predetermined time, one of the two power supplies is stopped. In a stationary operation, a low voltage is applied to the load, feeding the power by one power supply, utilizing the signal for commanding the feeding circuit to drive the load, a pulse width modulation output is created. Using the output, power is fed to the load via a transformer. Thereby, when the load is driven stationarily, fed is a voltage lower than the voltage when starting the driving operation. Power for driving a load is saved, and the delay of operation stop is improved.

The rotation-stop sensor is provided with a plurality of optical sensors (23A and 23B) and a disk (22) having light guiding parts (X1-X4) which guide light beams (PB1 and PB2) emitted from the light emitting means (23A and 24B) of the sensors (23A and 23B) to light receiving means (25A and 25B), and light intercepting parts (Y1-Y4) which intercept the light beams (PB1 and PB2). The parts (X1-X4 and Y1-Y4) are arranged alternately along the outer periphery of the disk (22). The optical sensors (23A and 23B) are arranged so that either of the sensors (23A and 23B) is always in a region facing one of the light guiding parts (X1-X4). When the disk is at rest, therefore, the output of either of the sensors (23A and 23B) is always at a high level and the stoppage of the disk (22) can be detected from the direct output of the sensor (23A or 23B).
