    摘要： Delay time variation in an optical fiber digital communication system which includes optical regenerative repeaters is measured at one of terminal ends having reference clock signal. A monitor signal which depends upon the delay time variation is provided at the farthest repeater in an area where delay time is subject to secular change by dividing reference clock signal from said terminal end, and said monitor signal is returned to the terminal end from said farthest repeater, and the terminal end compares the returned monitor signal with the divided reference signal by using a phase comparator to provide measure of delay time variation.

    摘要： An optical switch for switching laser beams, having a transparent glass plate with a reflection film on the surface of the same has been found. When the reflection film is at the first position, the first input beam is coupled with the output beam through the transparent glass plate, while the second input beam is prevented by said reflection film. When the reflection film is at the second position, the first input beam is prevented by said reflection film, and the second input beam is coupled with the output beam through the reflection by said reflection film. Thus, according to the displacement of the transparent glass plate together with the reflection film, the input beams are switched. Due to the above operational principle, the output optical level does not decrease even during the transient time, and then, the present optical switch is utilized in an optical repeater for digital communication.

    摘要： An eyeglass-shaped frame includes: a pair of temples; a connecting bar connecting ends of the pair of temples; a shaft hanging from a middle of the connecting bar; nose pads fixed to the shaft; a pair of holding frames holding vertically arranged optical members; a bridge connecting the pair of holding frames; and a slider allowing the holding frames to slide vertically in front of the connecting bar. The bridge is provided at a position lower than a center of the lower optical member of the holding frames. The holding frames are slidable for a distance at least corresponding to a distance between a center of an upper optical member and the center of the lower optical member.
