Patent number: 5595516Abstract: A catalytic exhaust system for an outboard motor wherein the catalyst is positioned in the drive shaft housing to remove this source of heat from the power head. However, the catalyst is contained within a sealed compartment in the drive shaft housing lower unit. In order to protect the catalyst from water, a trap section is positioned in the power head and this is water cooled by a source of water which has not passed through the engine for its cooling prior to delivery to the trap section. In addition, the guide plate that separates the power head from the drive shaft housing and through which the exhaust gases pass is also water cooled. An arrangement is incorporated for permitting replacement and servicing of the catalytic converter. Although both above the water and below the water exhaust gas discharges are employed, all gases flowing to the atmosphere must pass through the catalytic converter.Type: GrantFiled: July 25, 1995Date of Patent: January 21, 1997Assignee: Sanshin Kogyo Kabushiki KaishaInventors: Naoto Matsumoto, Hiroaki Fujimoto

Patent number: 5526563Abstract: A flexible wiring board is constructed by placing, on a surface of a flexible ultraviolet-transmissive base member in the form of a layer, a conductive member in the form of a layer and a covering member in the form of a layer. The conductive member has an exposed leading area not covered with the covering member. A lead is aligned with an electrode and they are connected together with pressure exerted by a pressure applying jig which is ultraviolet-transmissive. A photosetting adhesive resin capable of shrinking in volume is injected between the flexible wiring board and a printed circuit board. The photosetting adhesive resin is irradiated with ultraviolet passing through the pressure applying jig and the base member. When irradiated with the ultraviolet rays, the photosetting adhesive resin hardens. Volume shrinkage force exerted by the photosetting adhesive resin enhances the connection between the lead and the electrode.Type: GrantFiled: March 9, 1995Date of Patent: June 18, 1996Assignee: Matsushita Electric Industrial Co., Ltd.Inventors: Tomohiro Tamaki, Kouichi Nagao, Hiroaki Fujimoto, Kazunari Nishihara
