Filed: 1988-10-26
Abstract: PURPOSE:To perform stabilized manufacturing of a molded product by maintaining always a fixed injection quantity of resin, by providing a coil spring made of ceramics pressing always a check ring in the direction of a check sheet. CONSTITUTION:When a sending action of a molten resin 20 is stopped through suspension of a rotation of a screw 4, a check ring 6 is slided rightward immediately with pressing force of a coil spring 7 and shifted to a back current checking state where its tapered torus 6b is stuck close to a check sheet 8. Since the check ring 6 is under the back current checking state where the check ring 6 is oppressed by the coil spring 7 and stuck close to a check sheet 8 even if resin pressure on a front side of the check ring 6 is made more negative pressure than that on a rear side of the check ring 6 by controlling a suck back prior to an injection stroke, a measured quantity of the resin is maintained constant always. Then since the coil spring 7 is made of ceramics, the same is rich in heat resistance, there is no fear of deterioration in thermal spring characteristics even under a using state of high heat, for example, of about 300-400 deg.C and a stabilized action can be guaranteed extending for a long period of a time.

Filed: 1988-10-25
Abstract: PURPOSE:To prevent an optical cable for infrared rays from being damaged by heat by providing a gas introducing device in the vicinity of the outgoing end of the optical fiber and blowing a gas flow on the end face. CONSTITUTION:This optical fiber 21 is inserted into a tube 22 and a gas introducing device 23 is attached to the front end section of the tube 22.
