Patent number: 5817892Abstract: A process for producing an unsaturated alcohol wherein the catalytic activity and the capability of maintaining double bond are sustained for a long time and side-reactions are suppressed. An unsaturated alcohol is obtained by hydrogenating an alkyl or alkenyl ester of an unsaturated fatty acid or a triglyceride having a long-chain aliphatic unsaturated hydrocarbon group in the presence of a catalytic composition which is a composite metal oxide consisting of (a) zinc oxide and (b) oxide(s) of at least one metal selected from the group consisting of the elements of the group 3A in the periodic table and having a weight ratio of (a)/(b) of from 1/0.01 to 1/1.2.Type: GrantFiled: August 21, 1997Date of Patent: October 6, 1998Assignee: Kao CorporationInventors: Hiroyuki Tamura, Hideo Tahara, Yoshinori Mitsuda, Yasuyuki Hattori

Patent number: 5151058Abstract: A supporting device for an outboard motor comprises a stern bracket, and an outboard motor bracket. A guide is arranged to the stern bracket, and thrust and reverse rails are mounted thereto. The outboard motor bracket has one end supporting the outboard motor, and the other end including upper and lower arm portions. The upper arm portion is engaged with the guide, and the lower arm portion includes a thrust roller which is slidably engaged with the thrust and reverse rails.Type: GrantFiled: April 17, 1991Date of Patent: September 29, 1992Assignee: Nissan Motor Co., Ltd.Inventors: Hideo Tahara, Nobuo Makihara

Patent number: 5078632Abstract: To reduce engine exhaust gas pressure behind a motorboat propeller formed with a boss for educing engine exhaust gas therethrough, without forming a trumpet-shaped boss end and without allowing exhaust gas to flow upstream along the boss outer surface, a single or plural small subblades are provided between two adjacent large main blades at such a position that a positive pressure domain produced by the subblade reduces a negative pressure domain produced by the main blade. Since engine exhaust gas can be effectively educed, engine power increases and therefore motorboat acceleration performance can be improved.Type: GrantFiled: August 17, 1990Date of Patent: January 7, 1992Assignee: Nissan Motor Co., Ltd.Inventors: Toshimitsu Ogawa, Shouichi Takahara, Hideo Tahara

Patent number: 5041032Abstract: An outboard motor supporting arrangement of a boat includes a stern bracket fixed to a transom of the boat. The stern bracket is U-shaped, and has a flat bottom and left and right side walls extending upwardly from left and right ends of the bottom. Each side wall includes a slant section and a vertial section extending upwardly from an upper end of the slant section. In each side wall, there is further formed a projecting portion projecting outwardly, and extending longitudinally of the boat, for preventing water from be splashed on the outboard motor.Type: GrantFiled: December 22, 1988Date of Patent: August 20, 1991Inventors: Nobuo Makihara, Hideo Tahara

Patent number: 4950189Abstract: An outboard motor supporting arrangement includes a stern bracket fixed to a transom of a boat, a lift member which supports the outboard motor and which is connected with the stern bracket so that the lift member is movable up and down and swingable together with the outboard motor, a vertically extending tilt cylinder which is connected between the stern bracket and lift member for causing the lift member to move up and down, and a pair of horizontally extending trim cylinders which are provided between the stern bracket and lift member, for causing the lift member to swing. Each trim cylinder is pivotally supported on the stern bracket, and a rear end of each trim cylinder is provided with thrust rollers which rolls on the lift member. Alternatively, each trim cylinder is pivotally supported on the lift member, and the front end is provided with the thrust rollers abutting against the stern bracket.Type: GrantFiled: December 22, 1988Date of Patent: August 21, 1990Assignee: Nissan Motor Co., Ltd.Inventors: Hideo Tahara, Nobuo Makihara

Patent number: 4927392Abstract: A flexible duct is connected between the outboard motor and the hull transom, to supply air, fuel, power and control cables to the motor liftably and steerably attached to the transom, even when the motor sinks into water. To improve the durability of the flexible duct, that is, to allow the flexible duct not to be moved whenever the outboard motor is pivoted for steering operation, the air supply apparatus for an outboard motor comprises (a) a hollow steering shaft pipe fixedly supported near the transom; (b) upper and lower bearings, attached between the steering shaft pipe, for supporting the pivotal steering shaft of the motor; (c) a cylindrical cover for pivotably and slidably covering the upper end of the steering shaft pipe; and (d) a flexible duct connected between the transom and the fixed hollow steering shaft pipe.Type: GrantFiled: March 13, 1989Date of Patent: May 22, 1990Assignee: Nissan Motor Co., Ltd.Inventors: Nobuo Makihara, Hideo Tahara

Patent number: 4889507Abstract: An outboard propulsion unit supporting system by which an outboard propulsion unit is vertically movably supported to the rear end section of a boat. The supporting system is comprised of a pair of slit brackets installed to the rear end section of the boat. Each slit bracket is formed with a generally vertically extending slit in which a guide roller rotatably secured to the side of the propulsion unit is movably engaged. The boat is provided at its transom with a pair of thrust rollers on which a pair of generally vertically extending guide rails formed on the propulsion unit side are detachably contact, respectively. Additionally, a tilt cylinder is provided between the boat transom and the propulsion unit side thereby to raise the propulsion unit generally vertically.Type: GrantFiled: December 7, 1987Date of Patent: December 26, 1989Assignee: Nissan Motor Co., Ltd.Inventors: Hideo Tahara, Novuo Makihara, Hiroshi Ono
