Title: Optical connector
Inventor: SAITO KAZUTO
IPC: G02B6/36
Filed: 1989-03-27
Abstract: PURPOSE:To improve the strength of an optical fiber guide member by increasing the equivalent spring constant of a member which is variable in the up-down direction of grooves, and providing nonlinear spring characteristics which allow easy deformation at the time of pin insertion, but make deformation hard after the guide pin insertion. CONSTITUTION:The member 2 which is variable in the up-down direction of the grooves are in a U shape and provided in contact with the bottom surface and both flanks of the optical fiber guide member 1, and its end parts extend up and down and are bent by the guide pin grooves 14 of the optical fiber member 1 to form clamping parts 21 for guide pins A. The guide pins A are inserted into the guide pin grooves 14 to obtain reaction forces as clamping for the guide pins A by the elastic deformation of the guide pin clamping members 21 of the member 2 which is variable in the up-down direction of the grooves. The deformation quantity of the guide pin clamping parts 21 is extremely small, the equivalent spring constant is large, and the nonlinear spring characteristics are obtained. Consequently, the breakage strength of the optical fiber guide member 1 can be improved.

IPC: G01R15/06
Filed: 1989-03-27
Abstract: PURPOSE:To accurately detect a voltage with an inexpensive and easy method by changing the electrostatic capacitance of a voltage divider in the manner of moving in parallel a parallel electrodes couple in the voltage divider to the direction relatively opposed to each other. CONSTITUTION:The cylindrical voltage divider using for the detection, when the voltage of a high voltage cable 4 which is an object to be measured is detected by a sensor 3 in single form, consists of three structures of an inside cylinder electrode 1A, cylinder dielectric 2A and outside cylinder electrode 1B. When a length of parallel cylinder electrodes in the axis direction is taken as (l) and the electrodes are made to move in parallel by (l1) each other, the electrostatic capacitance of the voltage divider is increased by -l1lX100%. By such a parallel movement of the parallel cylinder electrodes, the electrostatic capacitance of the voltage divider can be adjusted; thereby a sensitivity variance of the voltage sensor caused from the sensitivity variance of the voltage sensor 3 in single form and the electrostatic capacitance variance of the voltage divider, is corrected.

Title: Automatic shifter of typewriter for electronic computer
Inventor: KAI MAKOTO
IPC: G06K15/08
Filed: 1979-06-14
Abstract: PURPOSE: To make it possible to change a print position after shifting, and also to shorten the time of a shift, by only counting space codes when they are input and then by making a shift through single operation as many as the integration number of space codes when non-space codes are input.  
     CONSTITUTION: Space codes among various codes are input to code comparing circuit 14, the output of which is sent to counter 16 to integrate the number of space codes. Following those space codes, character or symbol codes are input to a code comparing circuit, whose output is input to shift control circuit 10, the output of which moves carriage 4 horizontally as shown by arrow A. Accordingly, a light beam incident from light emitting unit 6 to photodetector 7 is cut off and every time it is cut off, a digit pulse is output; and then counter 16 performs subtraction until the integration number of space codes reaches zero. When the number reaches zero, the counter output is input to shift control circuit 10 and print control circuit 9, and consequently while carriage 4 stops, printer 4 is put into operation.

Title: Semiconductor photodetector device
Inventor: KATOU HIROAKI
IPC: H01L27/144
Filed: 1984-04-16
Abstract: PURPOSE:To provide no restrictions to a pre-amplifier connected to the output side, a receiver, a controller, and the like by a method wherein a photo diode and an amplifier of low output impedance which amplifies the output of this photo diode are formed on a single semiconductor chip. CONSTITUTION:A buffer amplifier 4 is added to a pin photo diode 1, which are formed on a single semiconductor chip. This buffer amplifier 4 sets the output impedance low. For example, setting at emitter follower output not only causes a low output impedance, but also allows the buffer amplifier 4 to have amplification, and enables the omission of a receiving pre-amplifier in the latter case. Since the output impedance is low, the input impedance of the pre-amplifier 2 and the like receiving the output of the buffer amplifier 4 is not restricted to high impedance; accordingly, the range of applications enlarges.
