  • Patent number: 7818921
    Abstract: A through section shielding construction is disclosed in which a partitioning wall defines a slit-like opening extending along a lateral direction as a moving passage of a penetrating member relative to the partitioning wall, and a plurality of shielding plates for closing the slit-like opening are juxtaposed along the slit-like opening as being suspended pivotally to be pushed open one after another by the penetrating member moving along the slit-like opening. The shielding plates are provided as adjacent pairs, and there is provided an operative coupling mechanism for operably coupling, with each other, two shielding plates constituting each pair in such a manner that in association with one of the paired shielding plates being pushed open in one direction by the penetrating member, the other shielding plate is pivotally opened in the opposite direction to the one direction.

  • Patent number: 7497321
    Abstract: A conveyor system including a crank arm having a base end portion rotatably supported by a second support axle and a free end portion rotatably supporting a suspended supporting apparatus, and a swinging arm having a base end portion fixed to a first support axle and a front end portion coupled to an intermediate position of the crank arm. A movable bearing stand supporting the second support axle is provided to be movable toward and away from a fixed bearing stand supporting the first support axle. Further, a suspended section parallel link mechanism of a suspended supporting apparatus is so configured that a free end support axle is located above a line connecting suspension pins at both ends of an upper frame.

  • Patent number: 4769925
    Abstract: A device for preventing resinous condensate dropping for use in a paint drying oven. The device includes a trough extending along an upper edge of a wall opening for passage of articles under drying treatment, to receive condensates of residual tar and guide them to laterally outwardly of the articles. The trough has a slate or other water-retentive member applied to an undersurface thereof to prevent formation of condensates on the undersurface. A glass wool member is interposed between the trough and slate to act as heat insulator.

  • Patent number: 4040716
    Abstract: A kaleidoscopic peep-show viewing device comprises an outer box of tubular shape with open opposite ends and with inscriptions printed on the inner surface thereof, an inner box adapted to slide telescopically within the outer box, and an optically reflecting member of peaked solid shape having a base, vertex, and mirror surface therebetween and joined at its base to one end of the inner box to slide thus unitarily therewith, the printed inscriptions, when viewed through one open end of the outer box as reflected images on the mirror surface, being optically collected thereby into single coherent pictures successively appearing and disappearing as the inner box is thus slid.
