Title: Sprue-less molding method, mold and molding
Inventor: IBE NOBUKUNI
IPC: B29C45/38
Filed: 1996-01-10
Abstract: PROBLEM TO BE SOLVED: To realize the injection molding of a sprue-less molding by means of the prevention of the cooling of a nozzle hole by the clearance at the tip surface of a nozzle, the complement of the bottom part of a cavity due to the thermal expansion of the tip part of the nozzle and the closing of the nozzle hole by a needle valve. SOLUTION: By forming the central part of the bottom surface of an injection cavity 15 with the flat tip surface of a nozzle member 4 internally installed in a needle valve, a nozzle hole is employed also for a cavity gate. Under the state that the required clearance is provided between the nozzle tip surface of the nozzle member and the bottom surface of the cavity, a molten resin is injected and filled in the cavity. The central part of the bottom surface of a bottomed molding is formed by a nozzle tip surface extended to the bottom surface of the cavity due to the thermal expansion of the nozzle tip part caused by the molten resin during filling.  By opening and closing the nozzle hole with the valve tip surface of the needle valve 43 under the state being flush with the nozzle tip surface, the bottomed molding 6 having no projection of a sprue at the center of the bottom surface is molded.

Title: Laser driver
Inventor: TAKIGAWA MASAMI
IPC: G11B7/125
Filed: 1990-01-29
Abstract: PURPOSE:To reduce the burden of a laser diode by providing the laser driving current input parts of an automatic light emitting power control circuit and an instantaneous writing light generation circuit respectively with analog switches, and providing a Schmitt trigger circuit between the input terminal of each analog switch and an integration circuit circuit connected to a logic power supply. CONSTITUTION:At the time of turning on power supply, the automatic light emitting power control circuit 4 is operated before the instantaneous writing light generation circuit 5, and at the time of turning off the power supply, the circuit 5 is stopped before the circuit 4 stops. Thus, the burden of the laser diode 1 due to turning on and off the power supply is reduced. For this purpose, switches to close logic input terminals 61, 71 at the high level are used for the analog switches 6, 7, and the positions of the inputs of the Schmitt trigger circuits 8, 9 are selected so as to be at the positions from the logic power supply through the integrator 10, since there is time lag by the integrator 10 in the inputs of the circuits 8, 9, the switches 6, 7 are turned into an open state. Namely, by making the opening and closing time of the switches 6, 7 different from each other, the extreme variation of the light emitting power of the diode 1 is removed.

Title: Film for wrapping goods which can be easily damaged
Inventor: KIM HEE JUNG
IPC: B65D65/38
Filed: 1999-01-27
Abstract: PROBLEM TO BE SOLVED: To obtain a film for wrapping goods which can be easily damaged such as food and to provide a method for producing the film. SOLUTION: This method comprises irradiation of a wrapping film with a far IR beam to cause electron deficiency, then which causes surface reaction which causes oxygen deficiency of one surface of the wrapping film. Therefore, if a container is wrapped with a wrapping film, and the film is exposed to the far IR beam, the film reacts with oxygen to lower the amount of oxygen in the container, and preservability of the food can be further enhanced.

Title: Focusing error detector
Inventor: GOTOU HIROSHI
IPC: G02B7/28
Filed: 1983-02-09
Abstract: PURPOSE:To reduce the size of a focusing error detector and to relieve the fitting precision of a photodetecting element by converting reflected light from an object and cutting off it partially, reflecting light which is not cut off and changing the direction of its optical path to a specific direction, and making the light incident to the photodetecting element. CONSTITUTION:The lower half part of light converged by a condenser lens 7 is cut off by a knife-edge 8. The remaining part which is not cut off is reflected by a plane reflecting mirror 9a to change the direction of its optical path by about 180 deg., and enters a couple of photodetecting elements 10. When a disk 6 is at an out-of-focus position, much light enters one photodetecting element 10 from the other to detect a focus error. Thus, the direction of the optical path is changed by about 180 deg. through the plane reflecting mirror 9a, so the size is reduced. Further, the focal length of the condenser lens 7 is set longer, so the spots of beam waists on the photodetecting elements are expanded to relieve the fitting precision of the photodetecting elements.
