Title: Quadrature detection circuit
Inventor: WATANABE KAZUO
IPC: H03D3/06
Filed: 1978-09-22
Abstract: PURPOSE: To make stable the parasitic capacitance between the base and collector of Tr and to increase the characteristics for detection, by connecting the collector of the emitter follower transistor Tr to obtain the switching single to the constant voltage source.  
     CONSTITUTION: The phase circuit 1 consists of the tuning circuit to FM carrier and the phase shift circuit delaying the phase by 90° to the center frequency, and the output from the circuit enters the multiplication circuit 2 via the buffer amplifier 3 as the switching signal. The amplifier 3 prevents the effect of impedance at the circuit 2 to the circuit 1, and it consists of TrQ 8 , Q 9 , and emitter resistors R 6  and R 7 , and the collector voltage is fixed at the constant voltage source circuit 4 to keep a constant and small value for the junction capacitance between the base and collector of TrQ 8 , Q 9 . Thus, the variation of the tuning frequency at the circuit 1 is avoided to obtain excellent detection characteristics.

Title: Discriminating device for proximity switch
Inventor: YOKOMORI SHINJI
IPC: H03K17/95
Filed: 1989-05-10
Abstract: PURPOSE:To increase the accuracy of a proximity switch by storing the count value of a counter which is outputted when no metal exists around a detection coil, and deciding the presence of a metal when the detected count value is smaller than the stored count value by an amount larger than a prescribed level at the time of using the proximity switch. CONSTITUTION:A counter 11 counts previously the output pulse number 3a of a comparator 3 at the time of adjusting a proximity switch in a state where the metal to be detected within a magnetic flux produced by a detection coil L. The count value M of the pulse 3a is written into a memory 15 via a writing means 13. Then the value M written into the memory 15 is loaded to a count value deciding means 12A by a reading means 14 at the time of using the proximity switch. The means 12A compares the value A of the counter 11 that counted the number of pulses 3a with the threshold value (M-alpha) obtained by subtracting the prescribed value from the value M to decide the absence of a metal with A>=M-alpha and the presence of a metal with A<M-alpha respectively. Thus a proximity switch of high accuracy is obtained.
