Title: Data receiver
Inventor: TAKIZAWA HIROSHI
IPC: H04L27/233
Filed: 1993-06-24
Abstract: PURPOSE:To remove phase uncertainty caused by synchronization detection. CONSTITUTION:A 4-phase PSK demodulation circuit 68 demodulates a 4-phase PSK modulated signal by synchronization detection. A phase conversion circuit 70 outputs two outputs Ia and Qa of the demodulation circuit 68 as they are for a while. A synchronization detection circuit 72 detects the synchronization data of a transmitted frame from the outputs of the phase conversion circuit 70 and when the synchronization data are not detected yet, a pulse signal is impressed to the phase conversion circuit 70. According to the pulse from the synchronization detection circuit 72, the phase conversion circuit 70 outputs the two outputs Ia and Qa from the demodulation circuit 68 after inverting those phases. Thus, outputs I and Q from the phase conversion circuit 70 turn to right phases.

Abstract: PURPOSE:To push and press an overshoot of voltage in case of starting of a generator by providing a variation compensating circuit of output frequency of the generator to a voltage variation detection circuit detecting variations between voltage of the generator and voltage setting. CONSTITUTION:Voltage of a generator 1 is obtained by a PT 4 and a voltage detection circuit 5 to compare with voltage (VS) to be set 6, and is inputted to a comparator 11. On the other hand, frequency (f1) obtained from the PT 4 is interlocked with the voltage (VS) to make a frequency conversion 10, and is inputted to the comparator 11 as voltage V1. Immediately after starting, the voltage of the generator is lower and the output of the comparator 11 is higher, but voltage V1 is restricted, so that the output of the comparator 11 is also higher, and a phase controlling circuit 8 fully ignites a thyristor 3. A variation voltage is gradually lower with its starting. The voltage V1 reduces the input of the phase controlling circuit 8 to 'zero' even if differential voltage remains through the comparator 11, the voltage of the generator is set lower than the VS, and it gradually rises to correspond with the VS. According to the constitution, an overshoot of voltage in case of starting is controlled.
