摘要： In a switching circuit formed as an integrated circuit, a series circuit comprising a diode (D.sub.1) and a resistor (R.sub.1) is connected between a base and an emitter of an npn transistor (TR.sub.1) requiring a high speed switching operation. Therefore, a high speed operation is made possible. Furthermore, in a circuit constructed such that the above npn transistor is driven by a pnp transistor (TR.sub.3, TR.sub.4), a leakage current produced in the above pnp transistor at high temperature is allowed to flow in the above series circuit. Accordingly, a malfunction of the above npn transistor is prevented. Consequently, an integrated circuit operable even under high temperatures is achieved.

摘要： An oscillation circuit of a proximity switch includes a parallel LC resonance circuit (L, C), an oscillation transistor (Tr6) controlled by an output voltage from the resonance circuit for switching a constant current and a feedback circuit (Tr2, Tr3) for feeding back a current flowing through the oscillation transistor to the resonance circuit. In the circuit, there is further disposed a feedback current increase circuit including a second transistor (Tr7) controlled by an output voltage from the resonance circuit and a resistor (R) connected in series to the second transistor. The resonance circuit is supplied via the feedback circuit with a feedback current obtained by adding a current flowing through the feedback current increase circuit and a current passing through the oscillation transistor, thereby developing a large change in the amplitude of the oscillation.

摘要： The detection system comprises a sensor and a controller which are connected by two wires. The sensor can take more than two states as opposed to conventional detection systems. According to this arrangement, for instance, a small leakage current exists even when the sensor is in normal off state, and, therefore, electric current in the range of I1 to I2 flows even in normal off state. On the other hand, electric current of I3 to I4 flows in normal on state. When there is a wire breakage, no electric current flows. Conversely, when there is a shortcircuiting, electric current exceeding I4 flows. Electric current in the range of I3 to I4 corresponds to an unstable state which is neither normal on state nor normal off state. Thus, by distinguishing the level of the electric current flowing through the wires, by using suitable electric current level detecting circuit, which of the level classes it belongs to, a state signal corresponding to the result of this distinguishing process can be outputted for self-diagnosing purpose.

摘要： An operation section 2 is provided to a proximity sensor including: a detection section having an oscillation circuit 10; and an amplification section 2 having a function detecting a metal body using an oscillation amplitude of the oscillation circuit 10. In a set mode, when an operation to set an adjustment value for a sensitivity adjustment (a sensitivity adjustment value) is conducted in an operation section 22, CPU 20 generates a sensitivity adjustment signal in digital quantity indicating the sensitivity adjustment value and outputs the signal to a D/A converter 25. The sensitivity adjustment signal digital-to-analog converted by the D/A converter 25 is given to a feedback circuit 13 through a voltage adjustment circuit 26. Since the feedback circuit 13 is designed so as to change a feedback current quantity according to an applied voltage, a current with a magnitude matching a value the sensitivity adjustment signal is fed back to a resonance circuit 11 to thereby control an oscillation amplitude.

摘要： A chemical filter unit 10 is made of a chemical filter 12 and a filter life detection sensor 1. The filter life detection sensor 1 is provided with an adsorption state detection sensor 3 and a reference sensor 4 to which a flow of air is blocked. The sensors 3 and 4 are made of the same filter material as the chemical filter 12 with a pair of electrodes sandwiching the filter material. An oscillation circuit, in which the sensors 3 and 4 constitute a part of the oscillating conditions, detects changes in impedance of the sensors 3 and 4 based on the changes in oscillation frequencies. A measurement of the adsorption state detection sensor 3 is corrected with a measurement of the reference sensor 4 in order to remove effects of temperature and humidity, obtain a measurement corresponding to the amount of adsorption of chemical substances, and decide on the timing of replacing the chemical filter based on the corrected measurement.
