Title: Line switching device for digital communication system
Inventor: INOUE KUNIAKI
IPC: H04B1/74
Filed: 1987-12-15
Abstract: PURPOSE:To eliminate an unnecessary action generation to accompany a line switching interruption at a receiving terminal side by holding and giving an AGC feedback signal in the condition of an equalizer just before a signal interruption even in the middle of a bipolar input signal interruption by means of a signal interruption detection holding circuit. CONSTITUTION:An input signal interruption detecting circuit 21 inputs a bipolar input SBI, outputs a switching signal S21a to a switching circuit 23 immediately when the signal level goes to '0', energizes the switching circuit 23, simultaneously, outputs a holding signal S21b to a holding circuit 22, and causes the holding circuit 22 to hold the equalizing condition of an equalizer 1a just before the signal interruption.

Filed: 1986-12-26
Abstract: PURPOSE:To obtain a stable and accurate waveform by driving and controlling only a light source corresponding to one scanning light among plural scanning light beams while the scanning light is guided to a beam photodetection part according to a horizontal synchronizing signal. CONSTITUTION:Two layer diodes 50 and 51 emit two laser beams 309 and 310 as scanning light beams and only one laser beam 209 between the two laser light beams 309 and 310 has its scanning end reflected by a reflecting mirror 307 (while the other is turned off). A beam light detector 308 generates the horizontal synchronizing signal with the reflected scanning light and this horizontal synchronizing signal is used to time the recording of video data, i.e. the light emission of the laser diode. Therefore, only one light beam is allowed to pass on the beam light detector 308. Consequently, the quantity of light to the beam light detector and the shape of the beam light are stable and the stable and accurate output waveform is obtained from the beam light detector.
