摘要： PURPOSE:To facilitate the manufacture and to select the best material for an optical fiber by filling resin which can be molded below the heat-resistance temperature of a heat-resisting optical fiber in a mold and molding a substrate where the optical fiber is embedded integrally. CONSTITUTION:The heat-resistive optical fiber 2 consisting of a core 3 and a clad 4 is arranged in a specific shape in a metallic mold before the substrate 1 is molded by injection. While the optical fiber 2 is arranged, the resin is injected at temperature lower than the heat-resistance temperature of the optical fiber 2 to obtain the molding consisting of the substrate 1 and optical fiber 2 in one body. Then an electric circuit which includes a light emitting element 5 and a light receiving element 6 is combined to provide the function of an optical waveguide substrate. Consequently, while man-hours are decreased, the buried molding plate can be manufactured and materials and optical characteristics which are not limited to the conditions of injection molding can be selected over a wide range.

摘要： PURPOSE: To make tensile force make without being affected by the degree of stored wire quantity by adding means for controlling a tensile force- generating means attached to a body part consisting of a fixed pulley and a movable pulley. CONSTITUTION: A rotation sensor 13 detects the rotating speed of a movable pulley. The rotation sensor 13 and a converter 14 detect and convert the rotating direction and the rotating speed for absorbing difference in a small state between delivery quantity and winding quantity as far as the position of the movable pulley 5. An output signal is inputted to a correction amplifier 16. Where, a signal relating to reference tensile force set by means of a tensile force setting device 15 is inputted to the correction amplifier 16. Addition and subtraction based on both the signals are done. Inputting a correction signal providing appropriate tensile force to a clutch power supply 17 generates appropriate torque in a clutch 11 of a tensile force-generating means. Thus, wire storage can be performed with low tensile force without being affected by a variation in weight or mechanical loss of a linear body.
