Title: Optical fiber guide structure
Inventor: KATO TAKESHI
IPC: G02B6/00
Filed: 1988-11-14
Abstract: PURPOSE:To prevent the tip of a through hole from chipping and to guide an optical fiber tightly by setting a finite maximum value as the curvature of the surface of the optical fiber which contact the through hole and bringing the both into contact on their tapered parts. CONSTITUTION:The maximum value of the curvature of the optical fiber surface at the contact position between the optical fiber 1 and through hole 8 is made finite. Then the intersection of the tapered part of the fiber 1 and the tapered part of the through hole 8 are brought into contact with each other at the contact part 4. Consequently, the part of the optical fiber which is stressed in fiber fitting moves inward from the tip of the through hole and the fiber is stressed at the part where the mechanical strength is large. Further, the force in the fiber fitting is applied from the fiber surface to the through hole surface because the tapered parts contact each other, no sharp stress convergence is caused and chipping is prevented, so that high-accuracy positioning is performed.

Title: Power unit
Inventor: SHINGYOJI RYUJI
IPC: H02J9/06
Filed: 1996-10-29
Abstract: PROBLEM TO BE SOLVED: To provide a power unit in which downsizing and lightening of the capacitor to supply load with power can be made for emergency stop processing, and reduction of the power consumption of the internal power source is possible. SOLUTION: In the capacitor 14 of a power unit 1, charge is accumulated based on the output voltage on the voltage level higher than the voltage generated in a stabilizing power circuit 15 from a voltage level converting circuit 12. Therefore, the quantity of charge stored in the capacitor 14 increases, and the value of the capacitance C of the capacitor 14 can be made small. Moreover, since the voltage detecting circuit 13 is connected to the output stage of the voltage level converting circuit 12, it is not influenced by the internal resistance of a power source 11 (battery). Therefore, it becomes possible to make full use of the essential battery capacity.
