The phase difference detector 23 compares the phase of a carrier at the generating side of the QPSK signal and the phase of the recovered carrier generated from a VCO 24 and supplies a control signal to the VCO 24 so as to make the difference zero. The recovered carrier signal having a frequency being 8 times the frequency of the carrier from the VCO 24 is outputted and fed to shift registers 38a-38h comprising D-FF circuits and signals whose phase is deviated by 45 deg. each is outputted. The signal whose phase is deviated by 90 deg. is used as a clock signal and the phase is compared with the phase of the carrier of the QPSK signal and processed so that the phase difference is zero. Thus, the operation is made stable by the digital processing and multipliers, LPFs and phase shifters are all integrated.

Title: Control signal generating circuit
Inventor: KOBAYASHI TAKAMASA
IPC: H03K5/00
Filed: 1988-12-02
Abstract: PURPOSE:To generate a control signal from a control section without notifying the presence of a control inhibit period to a section to be controlled having the control inhibit period by changing the control signal sent in an optional timing into another control signal provided with the control inhibit period. CONSTITUTION:In case a control signal 11 at an L level to be inputted is in an inhibit period H, a flip-flop 1, an OR gate 2 and flip-flops 4, 5 are operated as shown in figure. That is, a control signal output 15 is generated from a NAND gate 6 till the escape from the inhibit period is awaited. After the input of the control signal is once accepted, till a control end signal 12 is inputted, the next input is not accepted. Thus, even if the control signal input 11 is sent in any timing, the receiver side converts the signal into a control signal output 15 avoiding the control inhibit period and generates the result.

Title: Driving method in solid-state image pickup device
Inventor: MIYASHITA MASAYASU
IPC: H04N5/378
Filed: 1995-11-24
Abstract: PROBLEM TO BE SOLVED: To restrict noise since a pulse generation cycle becomes uncontinuous and balance with another pulse output is lost so as to give influence to a power source so that it becomes a cause for new noise in a screen when a sample-hold pulse is stopped at a position corresponding to a defective image element position in order not to fetch the signal level of a defective image element in a solid-state image pickup device. SOLUTION: In the driving method of the solid-state image pickup device, the output of the sample-hold pulse SP corresponding to the defective image element position of the solid-state image pickup device is stopped so as to cancel the fetching of the signal level L3 of the defective image element. At this time, a pseudo pulse MP with the same phase as that of the stopped sample- hold pulse SP is generated so as to output it to a dummy load. Thus, the occurrence of power source noise owing to losing the pulse output balance of the sample-hold pulse SP with another pulse CP is restricted.
