Filed: 1983-06-10
Abstract: PURPOSE:To obtain the large output voltage even with a low level of power supply voltage by forming a transistor 2-stage cascade constitution for a multiplier constituting an FM demodulation circuit. CONSTITUTION:The input FM signal is supplied to terminals 62 and 63 and limited by transistors (TR)1-3. Then the input signal undergoes a level shift through TRs 4-7 and is supplied to the bases of TRs 28 and 29 of a multiplier 74'. The limiting signal is applied also to an astable multivibrator circuit 72. The signal which is supplied from the circuit 72 with its phase delayed by a fixed time regardless of the degree of frequency change of the input FM signal is impressed to the common base of TRs 14 and 15 of the multiplier 74' via a level shift circuit 73. The H and L levels of the output of a level shift ciucuit 71 which are supplied to the TRs 28 and 29 are set higher and lower than the H and L levels of the output signal of the circuit 73 by a prescribed level. As a result, a signal current flows to the collectors of the TRs 14 and 15 even with a low level of power supply voltage. Then the FM signal is demodulated and delivered via an output circuit 75.

Title: Protective circuit against short circuit of converter output
Inventor: MUROOKA KIYOSHI
IPC: H02H3/24
Filed: 1995-04-06
Abstract: PURPOSE: To automatically interrupt the output of a converter and thus prevent damage due to short-circuiting, by making an output voltage detecting circuit, composed of a Zener diode and a photocoupler connected in series, detect an output voltage lower than a specified value and inactuate the photocoupler, and thereby turning off an FET. CONSTITUTION: With the output side of a converter 11 is in a short-circuited state, voltage between output terminals 7, 7 is reduced. When the voltage of a first Zener diode 13 falls below a Zener voltage, the light emitting diode of a photocoupler 15 stops emitting light; therefore, an optical transistor is put in the off state, and the gate voltage of FET 16 is put at no potential, which brings FET 16 in the off state. Thus the current i due to the energy emission of a capacitor 3 is interrupted, and semiconductor elements, such as the diode 4 and a FET 5, connected in series with the output circuit of the converter, are thereby protected.
