Patent number: 7818921Abstract: 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.Type: GrantFiled: February 15, 2007Date of Patent: October 26, 2010Assignee: Daifuku Co., Ltd.Inventors: Kyotani Hisashi, Izuru Matsubara, Kenji Sakita, Yoshikazu Hayashi

Patent number: 4769925Abstract: 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.Type: GrantFiled: July 20, 1987Date of Patent: September 13, 1988Assignee: Taikisha Ltd.Inventor: Izuru Matsubara
