Title: Frame synchronism control system
Inventor: SASHITA AKIHIKO
IPC: H04L7/08
Filed: 1990-09-19
Abstract: PURPOSE:To prevent synchronism from being erroneously established by defining a data excepting for a synchronous signal as a prescribed pattern different from the synchronous signal until synchronism is established. CONSTITUTION:A compression/extension cordic 6 is equipped with a control part 1, decoding part 2 and encoding part 3 and in the control of the control part 1, the encoding part 3 encodes and compresses a PCM signal, which is applied from a data terminal through a PCM terminal 4, so as to transmit a framed signal from a compressed transmission line terminal 5 to the counter side cordic. On the other hand, the framed signal transmitted from the counter side passes through the compressed transmission line terminal 5 to the decoding part 2, is decoded/extended in the control of the control part 1 and transmitted through the PCM terminal 4 to a data terminal as the PCM signal. In this case, the bit excepting for the synchronous signal in a data frame is transmitted as the bit of the prescribed pattern until frame synchronism is established at the counter station. Thus, frame synchronism can be established without fail.

Abstract: PROBLEM TO BE SOLVED: To stabilize a motor drive voltage for maintaining constant logic voltage, if a motor supply voltage exceeds a specified range, by supplying a current equivalent to the excess to a second motor, and when the motor supply voltage falls back within the specified range, to stop the current supply. SOLUTION: A motor voltage is kept monitored by a VH detection circuit 1 during acceleration, constant-speed running and deceleration of a motor to determine whether the motor voltage has exceeded a set voltage. If it has, the VH detection circuit 1 notifies CPU 102 of that, and the CPU 102 starts excitation of a motor out of operation, or an LF motor 109, via an LF motor driver 107. When the excitation of the motor is started, energy stored as electric charges in a capacitor by energy regenerated from a motor in operation, or a CR motor 108, is discharged via the LF motor 109. The CPU 102 exciting the motor monitors whether the VH voltage fell back below the set value, and causes. If so, excitation to respect to the LF motor 109 is stopped.
