摘要： A device for confirming the stop of a motor, particularly a rotation sensor for extracting the rotation signals of the motor. In the first invention, a high-frequency current signal is supplied to the winding of a tachometer generator incorporated in a motor, and a modulated signal obtained by modulating the high-frequency signal with the output signal of the tachometer generator is output from the rotation sensor to direct the rotation of the motor. In the second invention, the rotation of the motor is extracted after converting the rotation into the variation of the oscillation frequency of an oscillator by utilizing a transducer coil as part of the oscillator. In the third invention, the rotation of the motor is extracted after converting the rotation into the variation of the terminal voltage of a resonance circuit by means of the resonance circuit incorporating the transducer coil.

摘要： 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.

摘要： A fail-safe signal transmitter whose output signals do not include errors even if multiple troubles occur in its circuits inclusive of a power supply device. Particularly, the transmitter is provided with a power supply monitor device, which includes a fail-safe window comparator and a fail-safe on-delay circuit for monitoring the power supply device. The output signal from the transmitter represents the conjunction of a power supply monitor signal, a signal to be transmitted, and a carrier.

摘要： A trouble monitor device for a bridge circuit which can reliably detect any trouble of a bridge circuit even when multiple troubles occur in a sensor circuit utilizing the bridge circuit. The change of an unbalanced output signal of the bridge circuit is monitored by a first window comparator (WC1) and the undesirable change of a power supply current for amplifying the bridge circuit (11) is monitored by a second window comparator (WC2) so that an output having a logical value "1" representing normality of the bridge circuit can be generated from an AND gate (13) when both monitor outputs are a logical value "1" representing normality.

摘要： Detection means detects the change of an impedance occurring in a coil in response to irregularities on the surface of a movable portion, and outputs its detection signal. A speed judgement circuit receives the detection signal from the detection means, and continuously generates a high level output signal when the detection signal changes after a predetermined time interval. A level detection circuit receives the detection signal, and generates a high level output signal when the detection signal is above a predetermined level. An AND circuit receives the output signals from the speed judgement circuit and the level detection circuit, and generates the output signal of the AND calculation. A movable portion stop report is made on the basis of confirmation that the delay of the report of the stop of the movable portion is reduced and moreover, a coil is normally combined with the movable portion, and the confirmation that the movable portion has been monitored immediately before the stop of the movable portion.
