Title: Synchronization protective circuit
Inventor: HIGUCHI HIROKI
IPC: H04L7/08
Filed: 1993-03-24
Abstract: PURPOSE:To provide the synchronization protective circuit of a small circuit scale by outputting synchronization/asynchronization flags from a flag inversion part when a frame pattern is detected at a prescribed position and when it is not detected by a control condition output circuit. CONSTITUTION:Whether or not FP is detected at the prescribed position is judged by a frame pattern FP detection circuit 20, a master counter 21, a decoder 10 and the control condition output circuit 24. When the FP is detected at the prescribed position during a rear protective operation by the control of the circuit 24, a sub counter 22 is counted up. When the prescribed FP is detected at the prescribed position over (m) frames, it is defined that synchronization is attained and the circuit 24 sends a flag inversion signal to a flag inversion blade 23 and lets the synchronization flag outputted. Also, when the prescribed FP is not detected at the prescribed position over (n) frames in a synchronous state, it is defined that asynchronization is attained and the circuit 24 sends the flag inversion signal to the flag inversion part 23 and lets the asynchronization flag outputted. Thus, regardless of the number of frames, the synchronization protective circuit of the small circuit scale with two counters can be obtained.

Abstract: PURPOSE:To prevent occurrence of a curl attendant on a habit of winding to improve a flatness by setting a difference of a birefringence ratio between the top and rear surface of a film to a specific value. CONSTITUTION:A difference of a birefringence ratio (DELTAn) between the top and rear surface of a film is set to be not less than 3X10<-3>. By winding the film with the surface of a small birefringence ratio inside, the film can be flat without a habit of winding in the longitudinal direction of the film at the time of secondary processing even when the film is supplied in a roll form as a primary product. In the method of producing the film, a difference of a birefringence ratio can be obtained by forcibly giving a temperature difference to the top and rear surfaces in any of an extrusion process, a casting and longitudinally orienting process, and a thermally fixing process, on the contrary by giving a cooling speed difference to the top and rear surface of the film, or alternatively by laminating polymers of different kinds by a co-extrusion system and using a difference of a crystallization speed between the both. For example, a material is extruded in a sheet form, one surface is cooled and set at a cooling speed of 10 deg.C/sec or more on a 10-40 deg.C casting drum, the other surface opposite to the casting drum is cooled by air, and the film is oriented.
