20090144761 | Disc drive device - A disc drive device includes a disc conveyance mechanism, a slide cam and a trigger slider. The disc conveyance mechanism has a cam driven element protruded on a movement route of the slide cam and a conveyance roller energized in a direction coming into pressure-contact with a disc by an elastic member. The slide cam has a cam contour part moving the conveyance roller in a direction being spaced apart from the disc against an elastic force of the elastic member while pressing the cam driven element. The cam contour part has a flat surface part formed in parallel to a moving direction of the slide cam, in order to move only the trigger slider, while restraining the slide cam by contact pressure of the cam driven element to stop the slide cam temporary, when conveying the disc inside a cabinet toward an aperture side of the cabinet. | 06-04-2009 |

20090178776 | DEVICE FOR MELTING, STORING, AND FEEDING METAL MATERIAL FROM BAR-SHAPED METAL MATERIAL INTENDED FOR INJECTION APPARATUS FOR MOLDING METAL PRODUCT - A device for melting, storing, and feeding a metal material is provided which can store a large amount of molten metal material corresponding to molding cycles with a compact configuration, using barrels to melt bar-shaped metal materials and a tank-and-barrel storage unit to store the molten metal material. The storage unit for the molten metal material is composed of an upper storage tank and a lower material temperature control barrel having a smaller diameter, the barrel being perpendicularly arranged under and in communication with the bottom center of the tank. The melting barrels for bar-shaped metal materials are made of barrel bodies having an inside diameter and a length appropriate to accommodate the bar-shaped metal materials. A more than one melting barrel is vertically arranged in parallel on a lid member of the storage tank, with their bottom openings facing the inside of the storage tank. | 07-16-2009 |

20090090749 | Method for preventing leaking of molten metal in injection molding of metal material - This is provided a method for preventing leaking of molten metal from a nozzle in an injection apparatus provided with a plunger within a cylinder body, a supply opening formed in an upper portion of the cylinder body, and a furnace for melting and holding the metal material provided on a top portion of the injection cylinder and having an outlet at the bottom end of the furnace communicated with the supply opening. The method comprises the following steps: metering the molten metal by travel of the plunger head backward from the most forward position to the backward position at the rear of the supply opening while maintaining nozzle touching after completion of an injection step and supplying the molten metal from the furnace into the cylinder body through the supply opening, after completion of the metering, closing the supply opening by travel of the plunger head forward at low speed from the backward position to a stand-by position ahead of the supply opening for cutting off the communication between the molten metal in the cylinder body and the molten metal in the furnace. | 04-09-2009 |
