Inventor: SEKINO TATSUO
IPC: B29C45/76
Filed: 1997-03-14
Abstract: PROBLEM TO BE SOLVED: To simplify structure by the use of a spring in place of hydraulic cylinder. SOLUTION: A plasticizing/kneading process of the type where a screw 2 is rotated by a hydraulic motor 3, and the screw 2 receives the movement pressure of plasticized material by the rear surface of a check valve, advances by compressing a coil spring 25, and stops its advancement when the shaft 2a comes in contact with the contact part 26a of a stopper 26. The screw 2 comes backward by the agency of the coil spring 25 at the same time of rotation stoppage in order to bring the check valve into close contact with the valve seat. In this state, the step of an injection process is started, however, counterflow is hindered because the check valve comes in close contact with the valve seat by the action of the spring 25.

Abstract: PROBLEM TO BE SOLVED: To obtain a distribution compensating optical transmission line and system capable of stably transmitting a WDM signal light over a long distance. SOLUTION: Until the 5 relay of 6 relay spans, distribution compensating fibers 40-1 to 40-5 compensate the accumulated wavelength distribution (and a distribution slope) of each wavelength so that the accumulated wavelength distribution of respective wavelengths λ1 to λn after compensating distribution may vary with respect to a distance (z) with Dlocal as inclination. A distribution compensating fiber 40-6 belonging to the last relay span of 6 relay spans reduces the accumulated wavelength distribution of the respective wavelengths λ1 to λn to an accumulated wavelength distributed value equivalent to a value Davg×z obtained by multiplying a transmission distance (z) to Davg. Dlocal is larger than Davg. Hereafter, this constitution is repeated by the unit of 6 relay spans.

Abstract: PURPOSE:To save the electric power and realize miniaturization of an image monitoring recorder which is used for the industrial purpose and under the unfavorable conditions, by providing both a tungsten lamp and a flash lamp together and using the flash lamp during an exposure for photographing. CONSTITUTION:A tungsten lamp 4 (illuminating light source for observation by naked eyes) is used in case the lamp is always lighted up for visual observation; and a flash lamp 5 of a high luminance is used for photographing with a short time of lighting. A light guide 3 can be used together with an image fiber 6, and a single- lens camera 7 is used to ensure simultaneous viewing. In such constitution, consecutive illumination is required but with a small luminous intensity. Thus the lamp 4 is used for observation by naked eyes since the lamp has a low luminous intensity with a consecutive emission of light; and the lamp 5 having a large luminous intensity is used for photographing which requires a large luminous intensity in a short time. As a result, the electric power can be saved as a whole, and at the same time miniaturization is attained for the device.
