    摘要: A container closure formed from a synthetic resin as a single unit has a circular top panel wall and a cylindrical skirt wall extending downwardly from the peripheral edge of the top panel wall. An outer cylindrical sealing protrusion, an inner cylindrical sealing protrusion, and annular sealing ridge, all having a predetermined shape and a predetermined size, are formed on the inner surface of the top panel wall. In one embodiment, the thickness of the center portion of the top panel wall is reduced to a predetermined range and a plurality of ribs having a predetermined thickness are formed on the inner surface of the center portion of the top panel wall.

    摘要: A method enabling stretch blow molding in a temperature range preferable for polyethylene and capable of releasing at a surface temperature suited to both releasing of a preform and subsequent stretch blow molding, by disconnecting the core die and the preform in advance by the use of pressure of gas. The injection molding of a predetermined preform involves filling an injection mold with molten polyethylene, releasing the preform from the cavity die and core die of the injection mold while a mouth portion of the preform is held by the lip die, and transferring the preform into a blow die to stretch blow mold into a hollow molded thin wall product. Gas forcibly enters into the boundary of the core die and the preform, before releasing the preform from the injection mold to isolate the inside wall of the preform from the core die. Releasing is effected while the inside of the preform is not completely cooled and is still at high temperature, and in a temperature range in which the surface temperature of the preform right after releasing is 80 to 90 deg. C. The step of stretch blow molding is performed within the time interval before the surface temperature of the preform which is elevated by the internal heat of the preform reaches 120 deg. C.

    摘要: A mechanism according to the present invention comprises a quadric crank chain disposed substantially within a vertical plane to support a test head of wafer probing machine, a cylinder mechanism coupled to a first movable link corresponding to the side opposite to a fixed link of the quadric crank chain, the cylinder mechanism serving to slide the first movable link in a vertical direction, and a guide member for supportingly guiding the cylinder mechanism in a horizontal direction. The test head is attached to a second movable link, which corresponds to a side adjacent to the fixed link of the quadric crank chain, so that the test head, along with the second movable link, revolves within the vertical plane when the first movable link slides vertically.
