IPC: H04J3/06
Filed: 1989-05-02
Abstract: PURPOSE:To shorten the time required for recurrence of multiframe synchronism by setting a prescribed count value to a counting means based on change information of the frame synchronous state, and starting the hunting operation for recurrence of multiframe synchronism simultaneously with settling of frame synchronism. CONSTITUTION:When the count value for division of multiframe is set to the counting means by a second control means in accordance with frame synchronizing information, which indicates that frame synchronism is settled, from a synchronism protecting means, a multiframe signal is outputted by the counting means. The synchronism disaccord state of multiframe is detected by a synchronism disaccord detecting means in accordance with this multiframe signal, and the timing of the counting operation of the counting means is shifted by a first control means in accordance with detection results. Thus, the prescribed count value is set to the counting means based on change information of the frame synchronous state in this manner to start the hunting operation for recurrence of multiframe synchronism simultaneously with settling of frame synchronism.

Title: Controlling method of motor
Inventor: SATOU ISAO
IPC: H02P7/29
Filed: 1979-09-04
Abstract: PURPOSE:To manufacture a control circuit of an integrated circuit and heighten the efficiency of the control circuit, by comparing the period of a real speed signal with the time of a reference speed signal and by feeding electricity in a next period if the period of the real speed signal is longer than the time of the reference speed signal but feeding no electricity in the next period if the period of the real speed signal is shorter than the time of the reference speed signal. CONSTITUTION:The revolution speed signal of the DC motor 1 is detected by a detector 14 and then applied to a rising detection circuit 16. When the output signal of the detector 14 has risen, the rising detection circuit 16 produces an output signal T synchronized with the output pulse of the reference oscillator 15. A counter circuit 16 counts the output of the reference oscillator 15 by a predetermined number to apply a reference time as an output 18 to a discrimination means 21. The output signal T of the rising detection circuit 16 is compared with the reference time by the discrimination means 21. If the output T is longer than the reference time, power is supplied to the DC motor 1 in the next period of the output T. If the output T is shorter than the reference time, no power is supplied to the motor so that it rotates by inertia. The output T is thus made coincident with the reference time.

Abstract: PURPOSE:To eliminate the need for a transmission timing adjustment circuit for a call signal and a reply signal from a command control trunk and a command telephone set by using a DTMF signal for a call and a reply of a command telephone line. CONSTITUTION:A DTMF signal sender circuit 2 sends a call signal 15 comprising a start flag 16, a call telephone set number 17, and a call telephone set ID number 18. An ID number comparator circuit 8 extracts its own ID number from an ID number of the call signal 15 received by a call signal register 7 and compares the ID with its own number. A reception control circuit 10 decrements a call telephone set number 17 by one, eliminates its own ID number from an ID number 18, edits the received call signal again and sends the result as a reply signal 19. A comparison control circuit 4 compares the reply signal 19 received by a reply signal register 3 with the call telephone set number 17 and the ID number in the call signal 15 respectively to confirm the reply of a command telephone set 6. The call control circuit 5 sends the call signal again when there is any non-reply command telephone set 6.
