Title: Video detector
Inventor: OKUNO KAZUHIKO
IPC: H04N5/46
Filed: 1989-05-30
Abstract: PURPOSE:To reduce number of externally mounted components in the case of circuit integration by switching an oscillating frequency while the current of a bias current source while the resonance frequency of a parallel resonance circuit of a VCO is fixed. CONSTITUTION:A bias current switching means 30 switches the current of bias current sources I1, I3 included in a voltage controlled oscillator (VCO) in response to the switching voltage to be supplied and a switch SW is thrown selectively to a bias current switching means 30 by using one of plural voltage sources set corresponding to plural frequencies of a video intermediate frequency signal. When the bias current changes, the oscillating frequency of the VCO is changed. Then the oscillating frequency (free run frequency) of the VCO is switched without changing the frequency of the resonance circuit included in the VCO. Thus, number of externally mounted components in the case of circuit integration is reduced and the cost is reduced.

Title: Logic arithmetic circuit
Inventor: YAMADA HACHIRO
IPC: H03K19/21
Filed: 1988-06-02
Abstract: PURPOSE:To obtain a high speed logic arithmetic circuit by reducing the number of transistors to be passed from an input to an output. CONSTITUTION:When a low potential to be logic '0' is given to a gate, P-type MOS transistors T1-T6 are conducted and when a high potential to be logic '1' is given, the transistors are opened. N-type MOS transistors T7-T12 execute reverse operation to the P-type MOS transistors T1-T6. When four signals are given as first and second input signals A and B and inverting signals -A and -B, only in case that the first input signal A and the second input signal B are equal, an output Q outputs the logic value '0' of the low potential and an inverting output -Q outputs the logic value '1' of the high potential. Thus, the delay of one gate is enough from the input to the output and since the signal passes through only two transistors, the high speed logic arithmetic circuit can be obtained.

Filed: 1997-05-13
Abstract: PROBLEM TO BE SOLVED: To provide a high frequency amplifier reduced in spurious radiation of an RF signal caused by a ripple component of a power source without adopting a complicated circuit configuration. SOLUTION: Outputs Vcc1, Vcc2 having ripple noises of opposite phases resulting from rectifying a secondary side output of a power supply transformer 5 by rectifier circuits 4a, 4b are fed to unit amplifiers 1a, 1b as power supply voltages. Outputs of the unit amplifiers 1a, 1b are combined by a power combiner 3 so that noises consisting of the ripple components are cancelled together. Thus, output voltages with ripple noises of the opposite phase are applied to pluralities of unit amplifiers so that RF signals modulated by the ripple noise are cancelled thereby realizing suppression of spurious radiation without using an additional circuit for modulation cancellation externally.
