A molding dieis constituted by an upper dieand a lower diewhich are made of a material transparent to an ultraviolet light, and has a cavityconstituted by grooves, whereas a resin injection gateand a resin exit gateare provided so as to communicate with the cavity. A junction of an optical fiberis inserted into the cavity. A UV-curable resin is injected into the cavitysurrounding an exposing portion of the glass optical fiberfrom the resin injection gatepositioned at one of coating ends of the optical fiber, whereas a part thereof is discharged from the resin exit gatepositioned at the other coating end. The ultraviolet light is emitted through the lower dieso as to cure the resin, thereby forming a reinforcement resin coating. As a consequence, bubbles can be prevented from occurring due to the residual air within the reinforcement resin coating in the junction of the optical fiber

MOLDING APPARATUS FOR A REINFORCEMENT RESIN COATING OF GLASS OPTICAL FIBER EXPOSING PORTION OF AN OPTICAL FIBER JUNCTION, METHOD FOR MOLDING REINFORCEMENT RESIN COATING OF A GLASS OPTICAL FIBER EXPOSING PORTION OF AN OPTICAL FIBER JUNCTION, AND OPTICAL FIBER CABLE

An engine-starting device for an engine. The device includes a counter that provides a counting value based on an initiation of engine cranking; and a cranking control system that prohibits engine cranking if the counting value of the counter passes a cranking prohibition threshold value.

Engine start system and method thereof

A method for handling a fusion-spliced optical fiber and a transferring jig for transporting the optical fiber are provided. The jig is capable of holding the fusion-spliced optical fiber in a state in which a given tension is applied at the spliced portion, and stopping the application of such tension if needed. The jig is easy to transport and set to each of separate processing processes. In the method, a fusion-spliced optical fiber is clamped at coated portions thereof on both sides of the fusion-spliced portion by a pair of clamps of the jig and transported by the jig holding the optical fiber in a state wherein a given tension is applied thereto through the clamps.

Method and jig for handling and transferring fusion-spliced optical fibers

In a method for molding an optical fiber fusion spliced portion, a mold coating is formed on a bare fiber portion of a fusion spliced portion of the optical fibers, using a resin compound having the characteristics where in a cured state, the tensile elongation is 70% or more and the tensile strength is 20MPa or more.
