Patent number: 5537935Abstract: Stringers are fabricated in the form of a tube. The tube in cross section as viewed from its ends has a substantially square shape. Each stringer is fabricated from a plate material which includes a rectangular lower plate and two side plates separately connected to both edges of the rectangular lower plate through respective folding lines. There are a pair of first support plates partially cut out of the lower plate. The support plates are connected to the lower plate along folding lines. These folding lines are located inwardly from both ends of the lower plate and are in parallel with these ends. There are a pair of upper plates separately connected to distal edges of the side plates through respective folding lines. Also, there are second support plates separately connected to distal edges of the upper plates through respective folding lines. A pallet including an upper deck and a lower deck includes a plurality of the fabricated stringers.Type: GrantFiled: August 26, 1994Date of Patent: July 23, 1996Assignees: Kabushiki Kaisha Tomoku, Kabushiki Kaisha RICInventors: Eiichi Otaguchi, Yasuo Yajima

Patent number: 5355625Abstract: Disclosed herein is a wood-cased glass door assembly in which a glass door that may be opened is composed of a glazing, and wooden stiles and rails, which are fitted on an outer peripheral edge of the glazing. The wood-cased glass door is mounted for opening and closing into a wooden doorcase fixed in an opening in a wall. Thermally expanding materials are separately installed in spaces defined between an inner peripheral portion of the wooden doorcase and outer peripheral portions of the wooden stiles and rails and between inner peripheral portions of the wooden stiles and rails and the outer peripheral edge of the glazing over the entire length in the longitudinal directions of the spaces. The expanding materials foam and expand under heat to block the respective spaces. Metal fittings for holding the glazing by putting the inner and outer surfaces of the outer peripheral edge of the glazing therebetween are fixed to the wooden stiles and rails.Type: GrantFiled: December 31, 1992Date of Patent: October 18, 1994Assignee: Kabushiki Kaisha TomokuInventor: Hisayuki Matsuoka

Patent number: 4132157Abstract: A scorer apparatus where a pair of driving shafts are disposed and below a sheet of corrugated cardboard or the like, separatable one from another provided with at least two pairs of mutually facing scorer members slidable in the axial direction to enable the sheet-like member to be applied thereon with score lines. Driving shafts are provided with plural moving shafts and each of the plural moving shafts on one side is connected to each corresponding one of the plural moving shafts on the other side through electrically driven shafts. Shifter members engage respective scorer members on each side and are in threaded engagement with each corresponding pair of moving shafts.Type: GrantFiled: June 16, 1977Date of Patent: January 2, 1979Assignee: Kabushiki Kaisha TomokuInventor: Tsutomu Shinomiya

Patent number: 3977928Abstract: An arrangement for manufacturing a fibrous sheet in which fibers are crushed and dispersed to form a layer of substantially uniform thickness and width. The layer of crushed fibers is conveyed as a continuous belt-shaped sheet layer, and adhesive is sprayed onto the crushed fibers. The sheet layer is then heated and compressed after being impregnated with the adhesive.Type: GrantFiled: August 15, 1974Date of Patent: August 31, 1976Assignee: Kabushiki Kaisha TomokuInventors: Saburo Odagiri, Jiro Hirano

Patent number: 3948385Abstract: An apparatus for inverting a sheet member comprising a pair of spaced conveyors cooperatively defining a conveyor passage along which a sheet member can be advanced, and a rotatable arm assembly mounted between the conveyors and including upper and lower arms defining an opening therebetween, adapted for receiving the sheet member from the upstream conveyor and conveying the sheet member to the downstream conveyor. The arms continue rotating back to the initial position after depositing the sheet on the downstream conveyor. The arms are driven at a non-uniform speed and accelerate from the initial position to an upright position and then decelerate from the upright position to the position adjacent the downstream conveyor.Type: GrantFiled: March 18, 1975Date of Patent: April 6, 1976Assignee: Kabushiki Kaisha TomokuInventor: Tsutomu Shinomiya
