Filed: 1987-07-29
Abstract: PURPOSE:To detect the signal of a prescribed communications channel without providing as many correlation detecting circuits as ever by timely switching a reference signal specified with a diffusion code corresponding to a communications channel by means of a convolver. CONSTITUTION:At a diffusion code selecting circuit 7, the diffusion code corresponding to the said communications channel inputted from a channel number generating circuit 6 is generated by a diffusion code generating circuit 8.

Title: Static electricity protection circuit for high frequency amplifier of transistor
Inventor: HIRAOKA SHIGEMI
IPC: H01P5/02
Filed: 1995-07-03
Abstract: PROBLEM TO BE SOLVED: To prevent the pass of a charged component of an impedance matching circuit by providing a BPF that has a pass band different from the parallel resonance frequency of the impedance matching circuit. SOLUTION: When the impulsive noises of high voltage caused by the static electricity are applied, the component equivalent to the parallel resonance frequency of a microstrip line 31 and a chip capacitor 32 is charged by an impedance matching circuit 3. However, the pass of the charged component is substantially prevented by a BPF 4 that has a pass band different from the parallel resonance frequency of the circuit 3. A slight amount of leaked component is discharged via a microstrip line 5 and therefore the noises caused by the static electricity are never inputted to an amplifier transistor TR 6. As a result, the voltage higher than the largest rated value is never applied to the TR 6.  Thus it is possible to improve the frequency discrimination ability just by adding the BPF 4, plural microstrip lines used for feedback of bias currents, and a chip capaictor to a conventional circuit.

Title: Inversion preventing circuit
Inventor: AKUTAGAWA TORU
IPC: H04N5/93
Filed: 1991-07-29
Abstract: PURPOSE:To prevent the occurance of an oscillating state when an input level is reduced by boosting frequency whose inversion is to be compensated in accordance with the reduction of the input level so as to prevent the generation of a black inversion phenomenon. CONSTITUTION:A brightness FM signal is supplied to a soft limitter 11b through an adder 11a and a non-linear circuit 12 constituting an inversion preventing circuit 11. The circuit 12 has a characteristic for interrupting the passage of a low level signal. An output from the limiter 11b is supplied to a sine wave filter constituted of an adder 11c and a delay line 11d and an output from the filter is positively fed back to the adder 11a through an attenuator 11e. The delay time tauD of the delay line lid is set up so as to satisfy f = 1/2tauD. Thereby the frequency (f) can be boosted while gradually suppressing the gain of the lower side band wave of the input level in accordance with the drop of the input level and the generation of the black inversion phenomenon can be prevented without being influenced by excess compensation. When the input level is reduced, the oscillating state for interrupting the passage of the low level signal does not occur in a feedback loop, preventing the generation of a bad influence to an image or the like due to oscillation.
