Title: Phase locked loop circuit
Inventor: NAKAJIMA AKIRA
IPC: H03L7/093
Filed: 1990-03-30
Abstract: PURPOSE:To vary the characteristic of the phase to the time of the whole of a phase locked loop(PLL) circuit and to improve the following-up characteristic of the PLL circuit by comparing the output signal of a loop filter with a reference signal and controlling the loop filter in accordance with the comparison result. CONSTITUTION:Normally, a switch 12 is closed to stop following-up to peak shift because the output voltage of a loop filter 7 is lower than the reference voltage of a reference power source 1. If the revolution of a motor is varied by  omega because of the occurrence of disturbance, a phase error ALPHAtheta between an output signal thetao and an input signal thetai is increased because this output signal does not follow up the quick change, and the output voltage of a loop filter 7 is raised in accordance with this increase. When the output voltage of the loop filter 7 exceeds the reference voltage of a reference power source 13, the switch 12 is opened to quickly follow up the revolution deviation of the motor with a small phase error. Thus, the PLL circuit is obtained where the following-up characteristic to the input signal is improved.

Title: Priority processing system
Inventor: SHIRONAGA MATSUO
IPC: G06F9/48
Filed: 1982-05-18
Abstract: PURPOSE:To select easily priority to be given to the request for processing from plural request originating devices, by using a register and a flag for holding, the number of a desired request originating device, and a flag inhibiting and controlling the request for processing. CONSTITUTION:When an inhibition information flag F2 is set for a signal other than a request for processing, i.e. to logic 0, an inverter 5-i outputs 1. The output of an OR gate 6-i is therefore 1 regardless of the output of an AND gate 2-i and all requests are signified. When the flag F2 is set to 1, on the other hand, the inverter 5-i outputs 0, so the output of the gate 2-i is shown by the output of the gate 6-i. In this case, when a flag F1 is set to 0, the gate 2-i turns off to inhibit all the requests for processing. When the flag F1 is set to 1, the request for processing from only a register R1 is sent to a priority determining circuit 8.
