Filed: 1994-06-30
Abstract: PURPOSE:To obtain the small sized optical DEMUX system capable of high speed operation without polarized wave dependency in the ultrahigh speed optical transmission system employing the optical time division multiplex technology. CONSTITUTION:A signal light subjected to time division multiplex and an output light of a clock light source 100 generating a periodic short pulse are synthesized and inputted to a semiconductor optical amplifier 101 and then an optical interferrometer 102 whose delay time is tau.

Title: Scanning system of facsimile device
Inventor: ISHIKAWA MASAAKI
IPC: H04N1/04
Filed: 1982-08-31
Abstract: PURPOSE:To eliminate uneven feeding of a high speed facsimile device, by applying plural feed pulses to a step motor for shifting one sub-scanning interval. CONSTITUTION:Four feed pulses P1-P4 are applied to the step motor to obtain one sub-scanning interval S1, and each pulse interval is set to 1/4 of a time T to be shifted for one sub-scanning interval S1. Since the one-sub-scanning interval S1 is carried continuously by the four feed pulses in a small interval, the shift of a recording paper at the first half the feed pulses, P1, P2 shows a slight vibration, lead or lag, to the feed pulses P1, P2, but hardly shows vibration to the latter half feed pulses P3, P4. Since the main scanning recording is performed in synchronizing with the latter feed pulse not showing the vibration, the uneven feeding is reduced possibly.
