Title: Spread spectrum communication equipment
Inventor: SUGA KAZUTOSHI
IPC: H04J13/00
Filed: 1985-04-26
Abstract: PURPOSE:To simplify the circuit by adopting a phase detector for the multiplication of amplitude information between a low-frequency oscillation wave and a demodulation signal in a spread code synchronizing circuit of the tau-dither system and using an addition signal between a tau-dither clock signal and a DC control signal for a control signal of a voltage controlled oscillator. CONSTITUTION:A spread code from a spread code generator C1 enters a multiplier M1 for inverse spreading. After an output of the multiplier M1 passes through an IF filter D11, the result enters a demodulator D12. A signal S11 representing the amplitude change by a tau-dither clock signal outputted from the demodulator D12 enters a phase detector C31, the phase is compared with that of a tau-dither clock signal S12 of an oscillator C35, a voltage level in response to the phase difference is outputted and enters an adder circuit C33 through an LPF C32. The circuit C33 adds this signal, an input signal for bias adjustment and the signal S12 to output a signal S14, which controls the oscillating frequency of a voltage controlled oscillator C34 to change the spread code generating speed at the reception side. The DC component of the signal S14 controls the entire generating speed and the AC component applies tau- dither. Then circuits for changing the phase by a voltage and detecting synchronization establishment are not required.

Title: Solid-state image sensing device
Inventor: NOBUSADA SHIYUNEI
IPC: H04N5/335
Filed: 1987-04-10
Abstract: PURPOSE:To prevent the overlapping of smearing signals, by providing an overflow Drain, which discharges extra signal charge, at the lower side of a horizontal CCD channel. CONSTITUTION:When extra signal charge is discharged into a drain 9, voltages phiH1H and phiH2H are applied to horizontal transfer gates 1 and 2. The extra signal charge is transferred to a horizontal transfer channels from vertical transfer channels. When the signal charge is excessive, the charge exceeds the capacity of the horizontal transfer channels. A drain voltage VD is applied to the drain 9 so as to absorb the excessive signal charge into the drain 9 through a counterstroke layer 8 having a reverse conductivity type with respect to the channel. Finally, the extra signal charge still remaining in the horizontal CCD is transferred to an output part as a dummy signal. Thus the overlapping of smearing signals can be prevented.
