Title: Frame synchronization circuit
Inventor: HAYATA MASAAKI
IPC: H04J3/06
Filed: 1997-08-21
Abstract: PROBLEM TO BE SOLVED: To attain frame synchronization with respect to a high speed SDH signal through a simple configuration. SOLUTION: Shift registers 4, 7 of a parallel configuration that receive data alternately for each bit are adopted for shift registers that apply serial parallel conversion to an STM-N signal in the unit of one byte and provide an output to ensure a timewise margin of data processing. An A1 byte in the two shift registers is controlled to appear in two patterns with output positions deviated by one bit each depending on the input sequence to the shift registers, so in the case an A1 byte detection circuit 6 detects an A1 byte at an improper output position, a 1-bit delay circuit 1 delays the STM-N signal by one bit to invert the input sequence so that the A1 byte is detected at the regular output position.  Then a counter 3 with one byte period to activate latch circuits 5, 8 is reset so as to provide an output of parallel data in the unit of one byte in conformity with the detection timing (phase).

Title: Variable magnification copying device
Inventor: OTA MITSURU
IPC: G03B27/50
Filed: 1988-09-22
Abstract: PURPOSE:To eliminate deficiency in exposure and decrease in exposure scanning speed by starting the exposure of an original at an exposure start position. CONSTITUTION:When an original platen fixed position indication member 43 comes to the position of a position detection sensor 44, the position detection sensor 41 sends out a signal to a CPU 47. Namely, when the position detection sensor 41 detects the relative movement position between an original and an exposure system, its detection signal is inputted to the CPU 47 as an exposure start position control means. A signal of copy magnification is also inputted to the CPU 47 and the exposure start position of the original is determined by the CPU 47, so that the original begins to be exposed at the position. Consequently, the deficiency in the exposure of an original exposure start end part is eliminated in reduction magnification mode and an unnecessary exposure time is eliminated in enlargement magnification mode to shorten a copying time.
