Filed: 1986-08-11
Abstract: PURPOSE:To always stabilize the control actions of a servo system by using the output of a horizontal synchronizing separation circuit as the synchronizing signal of the servo system and making the synchronizing signals different between at the time when the servo is stable and the time when the servo rises up. CONSTITUTION:The output from an optical head 1 is detected by a video detection circuit 2 and the reproduced output is added in a synchronizing separator circuit 3. The synchronizing signal separated in the synchronizing separator circuit 3 is differentiated in a signal composition circuit 13 and added in the horizontal synchronizing separator circuit 4'. The horizontal synchronizing separator circuit 4' outputs the signal including a fake sync and the omission of synchronizing pulses. And the servo action by a time base servo circuit 6 is monitored by a lock detection circuit 18 and the output from a synchronizing signal generator 5 through a delay circuit 11 is composed with the output from the synchronizing separator circuit 3 in the signal composition circuit 13. Thus, the horizontal synchronizing separate circuit 4' outputs the signals removed the fake sync and the omission of the synchronizing signal.

Title: Signal relay transmission system
Inventor: SHIMIZU HIROTOSHI
IPC: H04M7/00
Filed: 1991-07-03
Abstract: PURPOSE:To discriminate a signal representing a loss of its own station by an exchange and to prevent the deterioration in the operating efficiency of a relay line by providing a voice coding function and a bit addition/deletion function to the same module. CONSTITUTION:When a discrimination information detection means 9 detects discrimination information as to a signal from an exchange 1, a control means 10 switches selectors 4, 8 to the position of a bit addition section 3 and a bit deletion section 7 respectively. Thus, a compression signal from a relay line is added with bit information and discrimination information is added by a discrimination information addition means 5 via the selector 4 and bit information is deleted after the relay exchange and the result is sent to other relay line via the selector 8. On the other hand, when the means 9 does not detect discrimination information, the control means 10 switches the selectors 4, 8 to the position of a decoder section 2 and a coder section 6 respectively. Thus, the signal from a terminal equipment accommodated in the exchange 1 is coded and sent to a transmission line via the selector 8 and a compression signal from an opposite station is sent to the terminal equipment as a signal representing a loss of its own station.
