Title: Sweep frequency oscillator and quasi-synchronization detection circuit
Inventor: OI TOMOYUKI
IPC: H03J7/20
Filed: 1990-07-02
Abstract: PURPOSE:To attain data demodulation efficiently timewise by dividing a frequency sweep range into proper blocks, placing priority to the blocks and sweeping the frequency sequentially. CONSTITUTION:A frequency sweep range is divided equally into blocks shown in captions 22-26 with centering. The the priority of sweep is placed higher from a block closer to a center frequency Fc such as rank 1 to the block shown in the caption 24 and rank 5 to the block shown in the caption 26 and the frequency sweep is implemented according to the priority. As a result, since the frequency of a received carrier signal 21 is located close to the center frequency, the reception carrier recovery for a required frequency is implemented in a short time. Thus, the frequency sweep time is reduced and the carrier recovery is implemented efficiently.

IPC: G05B11/36
Filed: 1982-10-06
Abstract: PURPOSE:To prevent the deterioration of control accuracy as well as an unstable operation due to a hunting by providing the 1st blind sector as well as the 2nd blind sector having larger width than the 1st blind sector to control the operations. CONSTITUTION:A blind sector is first set at a region 1 with the potential set between V2 and V3, and T<V1 is satisfied for the control voltage T. Under such conditions, the potentials of output terminals (a)-(d) of comparators C1-C4 are set at L, L, H and H respectively. At the same time, an output Q is set at L to perform the control to the quantity to be controlled. In the case of V1<T< V2, the control proceeds with no change given to the state of an FF. The potentials of the terminals (a)-(d) are all set at L with V2<T<V3, and therefore the FF is set to discontinue the control. The control is kept under a pause state after the FF is once set even though the voltage T varies to V1<T<V2 or V3<T<V4. Then the FF is reset to start the control again when the voltage T satisfyes T<V1 or V4<T and is set to the outside of the region II.

IPC: G05F1/00
Filed: 1990-07-03
Abstract: PURPOSE:To obtain a reproduced clock with a proper phase by detecting the phase of the reproduced clock and a sampled clock so as to control the phase of a comparison signal. CONSTITUTION:When a data is inputted to a phase detection circuit 14, the data is delayed by delay lines 21a-21c by the phase of pi/3 each. A pulse is outputted at the Q output of a D FF 24a depending on the relation of phase of the data and a clock CK. No pulse is generated in the FFs 24a, 24b in the relation between the data and the clock CK'. A pulse is outputted only at the output Q of the FF 24b in the case of a clock CK''. When the frequency of occurrence of the pulses is extracted as a voltage by switches 25a, 25b and integration circuits 26a, 26b, 27a, 27b, the sign of a difference between the output pulses of the D FFs indicates the direction of phase shift and the sign of the sum of them depicts a phase shift quantity. The resulting control voltage is inputted to a phase control circuit 13 to very the phase of a signal Href, thereby matching the phase of the output clock CK of a PLL circuit 11 to an optimum phase with respect to the data.
