Title: Fm demodulator
Inventor: YOKOTA MASAFUMI
IPC: H04N5/94
Filed: 1980-02-25
Abstract: PURPOSE:To suppress a demodulation noise or a big transitional fluctuation of the demodulation output, by performing demodulation under the state, where the part corresonding to the time of the detection signal from the drop-out detecting circuit is substituted with the signal generated from the signal generating circuit, when the detection signal is output from the drop-out detecting circuit. CONSTITUTION:When drop-out of the FM carrier occurs due to the reproducing signal from the optical disc, drop-out detecting circuit 16 detects it and set the output to ''0''. Therefore, AND circuit 7 has the gate closed, and the output of fixed energized circuit 4 is inhibited from being supplied to LPF5. Meanwhile, signal generating circuit 10 generates a signal equivalent to the FM carrier; and when the output of circuit 16 becomes signal ''0'', the gate of AND circuit 9 is opened, and the signal of circuit 10 is supplied to LPF5. Thus, if the drop-out detection signal is output from circuit 16, the part corresponding to the time of this signal is substituted with the signal generated from circuit 10. As a result, demodulation noise and transitional great fluctuation of the demodulation output are suppressed.

Title: Glow plug preheating time controller
Inventor: HARA TOSHIZOU
IPC: F02P19/02
Filed: 1978-03-03
Abstract: PURPOSE: To provide an easy starting operation of an engine by detecting the coolant temperature of the engine by a thermistor, detecting the terminal voltage of a glow plug by the comparison with a constant-voltage circuit, and obtaining preheating time dependent to one another to thereby always provide an optimum preheating time.  
     CONSTITUTION: Since the output of a comparator A 1  is "H" level during preheating operation of an engine, a capacitor C is charged by currents added by a current I 13  flowing through a diode D 4  and a resistor R 13  and a current I 6  flowing through a diode D 1 , resistor R 6 , and transistor T 1  (I 6 <<I 13 ). Since the charged voltage V c  of the capacitor C is increased as the time is elapsed to invert the output of a comparator A 1  to become "L" level when exceeding the standard constant voltage VA, I 13 =0. Thus, the capacitor C is charged only by the current I 6 . When the voltage V 7  determined by the thermistor 7 is exceeded by the charged voltage V c  of the capacitor C, the comparator A 2  is also inverted to produce "H" level output to thereby turn the transistor T 2  off so as to notify the completion of the preheating operation.

Title: Variable gain amplifier
Inventor: TSUJI KIMIHISA
IPC: H03F1/32
Filed: 1998-02-05
Abstract: PROBLEM TO BE SOLVED: To enhance the linearity of an output characteristic of the variable gain amplifier. SOLUTION: An operational amplifier AMP2 is used for a feedback circuit of an operational amplifier AMP1. A variable voltage division circuit configured by connecting resistors R1, R2,... Rn and analog switches SW1, SW2, SW3,... SWn in a lattice shape is used as a feedback circuit of the operational amplifier AMP2 is employed. Since a voltage gain Vo/Vi (Vo is an output voltage and Vin is an input voltage) is nearly equal to a voltage division ratio of the variable voltage division circuit that is the feedback circuit of the operational amplifier AMP2, the output linearity is enhanced.  Since the analog switches SW1, SW2, SW3, ...SWn connect to terminals different from a terminal of the operational amplifier AMP2 to which an output voltage Vo is applied among input terminals of the operational amplifier AMP2, the error due to the on- resistance of the analog switches SW1, SW2, SW3,...SWn and the occurrence of the temperature dependence are prevented.
