  • Patent number: 7390188
    Abstract: A resin molding apparatus includes a fixing member to which a top mold is attached, a movable member to which a bottom mold is attached, a push-up member provided below the movable member, a drive mechanism moving the push-up member in upward/downward direction, and a flexible joint provided between the movable member and the push-up member. The push-up force of the drive mechanism is transmitted from the push-up member via the flexible joint to the movable member. Thus, a crack does not occur at a connection portion between the push-up member and the movable member. Therefore, a gap is not created between the top mold and the bottom mold. As a result, an excellent molded product is formed.

  • Patent number: 5445677
    Abstract: A treatment utilizing chemical vapor deposition is conducted on a major treatment surface (14) of a semiconductor substrate (8) under the condition where the semiconductor substrate (8) is held on a bottom surface of a stage (10) by suction force which is caused by reducing pressure in a vacuum pocket (13). In such a treatment, inert gas supplied by an inert gas feeder (24) is fed through a fluid duct (43) and inert gas feed holes (52) to an inert gas jetting gap (32) which is a space between an outermost circular surface (31) of an outer portion of a substrate holding surface (11) and a reverse major surface (12) of the semiconductor substrate (8). The inert gas is jetted out of the inert gas jetting gap (32) to a reaction chamber (6). Jets of the inert gas prevents undesirable objects or reaction byproduct (34) from easily penetrating in an inner region of the substrate holding surface (11).

  • Patent number: 4933540
    Abstract: An IC card has a shutter reciprocatively mounted on a frame in order to protect a plurality of external-element connection terminals which are mounted on the frame. Guide grooves formed in the frame include those which receive corresponding projections formed on spring-mounting portions of the shutter to keep the projections in engagement therewith, thereby enabling both the base portion and the spring-mounting portion of the shutter to be guided. End portions at one end of those guide grooves determine a position of the shutter such that the shutter is prevented from overshooting the frame. Thus, the IC card is capable of ensuring stable opening and closing action of the shutter.
