Abstract: A reinforcing sleeve for collectively reinforcing spliced portions of a plurality of optical fiber core wires disposed side by side includes a heat-shrinkable tube, a heat-meltable member, a tension member, and so on. The tension member and the heat-meltable member are inserted into the heat-shrinkable member. A thick portion is provided at a substantially center portion of a width direction of the heat-meltable member. Thus, on a cross section perpendicular to a longitudinal direction of the heat-meltable member, an amount of the heat-meltable member at proximity of the center portion of the width direction of the heat-meltable member is greater than an amount of the heat-meltable member at proximity of the end portions of the width direction of the heat-meltable member. This forms a flow of the heat-meltable member from the center portion toward the end portions in the width direction at the time of melting the heat-meltable member.

Abstract: A control system includes a system power supply IC that operates based on a voltage outputted from a power supply circuit and supplies a voltage for operating a microcomputer to the microcomputer, monitors an abnormal condition of the microcomputer, and outputs a reset signal for resetting the microcomputer to the microcomputer when detecting an abnormal condition of the microcomputer. When detecting the abnormal condition of the microcomputer, the system power supply IC outputs a switch opening signal for forcibly turning off a switch, which, in response to the switch opening signal, stops supplying the voltage outputted from the power supply circuit to the motor driving circuit.
