摘要： A mat sensor having high reliability, the failure of which is detectable even if it is temporary. In the first invention, two sensor portions (21, 22) are disposed as shown in the figure, and the states (ON/OFF) of the outputs of both sensor portions (21, 22) are detected. A signal indicative of normal condition is generated when the output states of the sensor portions (21, 22) are coincident. Under this condition a mechanical movement is permitted to operate if both sensor portions (21, 22) are OFF. In the second invention, an object is detected from a change in the capacitance value of a sensor portion. Even though only one sensor portion is used, a mechanical movement can be stopped by detecting even a temporary contact failure resulting from degradation of the sensor portion.

摘要： A detector (1) outputs a signal e1 corresponding to the operation of an object having an operation characteristic in which a transition from a first state to a second state occurs. A first state detection circuit (2) generates a first output signal SA corresponding to the first state on the basis of the signal e1 supplied thereto from the detector (1). A second state detection circuit (3) generates a second output signal SB corresponding to the second state on the basis of the signal supplied thereto from the detector (1). The second output signal SB is generated only when a transition occurs normally from the first state to the second state and during the period in which the first output signal SA is active. A state judgement circuit (4) generates a state judgement output signal Z under the condition that both of the first and second output signals SA and SB have a period in which they are simultaneously at a high level.

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.

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： A sensor capable of confirming the stop of revolution of a motor inclusive of rotation due to inertia. Signal input lines (A, B, C) are connected to three power feed lines (u, v, w) of an A.C. three-phase motor. A high frequency signal current is supplied to one of the power feed lines, and the difference between current values flowing through the other two power feed lines is extracted from the signal input lines connected to these two power feed lines and is used as the output for a sensor portion (3). Threshold value computation processing of this sensor output is executed by a signal processing circuit (7) and the result of this threshold value calculation output is output as a judgement output (P1) for judging the motor revolution or non-revolution from an ON/delay circuit (8).
