Title: Optical switch
Inventor: NAKAMURA SHIGERU
IPC: G02F1/35
Filed: 1996-01-19
Abstract: PROBLEM TO BE SOLVED: To provide a light-light control type switch capable of being operated with low energy and at high speed. SOLUTION: Non-linear optical waveguide 1, 2 and a control light delay circuit 10 are inserted into one arm of a Mach-Zehnder interferometer. Control light made incident from a port 12 changes its refractive index while being amplified by the optical waveguide 1 to which a bias current is impressed, and after being delayed only by T through the delay circuit 10, the delayed light is absorbed by the waveguide 2 and the refractive index is changed. Signal light made incident from a port 11 is branched by a 3dB coupler 3 and the branched components are allowed to interfare with each other by a 3dB coupler 4.  Although the signal light is projected from a port 13 in an initial state, the phase of the signal light is non-linearly shifted clue to the increment of the refractive index in the waveguide 1 in accordance with the incidence of the control light and the port for projecting the signal light is temporarily switched to a port 14. Since the signal light is influenced by both of the increment of the refractive index in the waveguide 1 and the reduction of the refractive index in the waveguide 2 after the delay of T, a total non-linear phase shift amount becomes zoro again and the projection port of the signal light is returned to the original port 13.

IPC: H03H17/02
Filed: 1988-01-18

Title: Data protecting device
Inventor: KUSABA RIYUUICHI
IPC: H04L69/40
Filed: 1983-01-20
Abstract: PURPOSE:To eliminate completely the occurrence of errors in data transmission at the power-on/off time, by using two kinds of DC power sources whose rise and fall are different from each other and controlling data on a data transmission line by the output of a comparator which detects the potential differential difference between DC power sources. CONSTITUTION:The output of a comparator 319 and output terminals of a microcomputer 320 are connected by diodes 313-316; and when the output of the comparator 319 is in the low level, the output of the computer 320 is fixed to the low level also. Consequently, even if abnormal data is generated from the computer 320 at the power-on time, miss data is not transmitted. The computer 320 is set to the low level by the comparator 319 until the comparator 319 becomes the low level after power failure. Therefore, data is not transmitted. Consequently, the transmission miss of the computer 320 at the power-on time or due to a momentary power failure or the like is eliminated completely.
