Abstract: A part holder comprising holding members (8, 9) extending upward on a base (10) to hold a part (11), insertion holes (12) penetrating the base (10) and passing lead wires (12) of the part (11) through when the part (11) is held by the holding members, and supports (17) extending downward on the base (10) and adapted to be supported on a substrate (15), on which a predetermined electric circuit is formed.

Abstract: An injection-compression molding apparatus includes a stationary mold provided with a nozzle for injecting molten resin, and a movable mold driven by a servo motor. In compressing the resin, high-speed position control of the movable mold is first performed, which is then switched to speed feedback control which enables delicate regulation of clamping pressure in accordance with pressure fluctuations in the resin.

Abstract: The present invention is a part retainer for housing and retaining various electronic and mechanical parts (27) wherein a retaining unit (2) has an engaging piece (7) that stably stops at both a position at which it protrudes toward the opening of a part housing space (5) and a position at which it withdraws, and which can move between these two positions under a specified or more amount of force, and wherein when protruding toward the opening, the engaging piece (7) prevents the part (27) housed in the housing space (5) from jumping out.

Abstract: A stamper protecting layer is interposed between a mold and a stamper of an optical disk molding apparatus, so that forces generated by extension and shrinkage of the stamper in a diametrical direction of the stamper relative to the mold when an optical disk are molded is absorbed by the stamper protecting layer. With this arrangement, the stamper is prevented from being deformed. Accordingly quality and production of the optical disks are improved.

Abstract: The present invention is a part retainer for housing and retaining various electronic and mechanical parts wherein a retaining unit has an engaging piece that stably stops at both a position at which it protrudes toward the opening of a part housing space and a position at which it withdraws, and which can move between these two positions under a specified or more amount of force, and wherein when protruding toward the opening, the engaging piece prevents the part housed in the housing space from falling out.

Abstract: A module is provided for a packaged IC designed to radiate heat by sealing the packaged IC. At least outer lead parts the packaged IC which are mounted on an electronic circuit board are sealed by a sealing material of a high thermal conductivity to form a sealing part.

Abstract: A molding apparatus for light-permeable articles which includes a nozzle that is movable up and down. A suction path and a suction device connected to the suction path are provided so as to suck a gas at a contact face of a sprue bush and its vicinity during the up/down movement of the nozzle. Accordingly, foreign substances, invading the mold can be sucked up before the apparatus performs a molding operation. Therefore, foreign substances are prevented from being mixed into the molded product. The molded product is accordingly improved in quality and yield.

Abstract: A component carrier assembly includes component holders each for holding a component therein and connected to one another in a form of a tape carrier. Each holder is provided with a cavity to accommodate the component, a closure for shutting an opening of the cavity, and a device for securing the lid structure in a closed position. An apparatus for feeding the component carrier includes a device for transferring the component carrier, a device for forcibly opening a closure of a component holder transferred to a predetermined position, and a device for forcibly closing the closure of the component holder after a component is removed from the cavity.

Abstract: The separation of a lower mold from an upper mold in an injection molding machine is either temporarily paused or carried out at a lower speed so as to maintain deformation of a thin component within a permissible range, while a jet of air is applied to help remove the thin component from the upper mold. Also, the ejecting operation of the thin component is either temporarily paused or carried out at a lower speed before the deformation of the thin component exceeds the permissible limit while a jet of air is applied to help remove the thin component from the lower mold.

Abstract: A component collective includes component holders respectively holding components therein and connected to one another in the form of a tape carrier. Each of holders is provided with a cavity to accommodate the component, a lid for shutting an opening of the cavity, and a keeping device for keeping the lid at a closed position. An apparatus for feeding the component collective includes a device for transferring the component collective, a device for forcibly opening the lid means of the component holder transferred to a predetermined position, and a device for forcibly closing the lid of the component holder after a component is removed from the cavity.

Abstract: A mold clamping apparatus of an injection molding machine is provided, which is capable of uniformly applying a pressing force to a movable platen. A pair of annular wedge type connection members (21, 22) are disposed within annular hollow portions (16a) of driving pulleys (16), which are respectively fitted on ball screws (14, 15) threadedly engaged with heads of upper and lower toggle sections disposed symmetrically with respect to an axis of the mold clamping apparatus. To make an adjustment for eliminating mismatch between operational phases of the toggle sections of the toggle mechanism due to flexure of the same mechanism, an urged contact state of the connection member is released by loosening bolts (23), and the ball screws, rendered to be rotatable relative to the driving pulleys, are manually rotated so that the heads are aligned with each other. After completion of the adjustment, the driving pulleys are again rendered rotatable in unison with the ball screws.
