Patent number: 9150256Abstract: A vehicle hood structure capable of improving impact absorption ability prior to a secondary impact when an impacting body impacts the hood. Front end portions of beads of a wave shaped section are arranged in a line in hood plan view. A front wall section is provided further to the hood front side than the wave shaped section and is formed inclined towards the hood bottom side on progression towards the hood front and running substantially along the vehicle width direction. The wave shaped section and the front wall section are connected together by a ledge section formed running substantially along the hood width direction.Type: GrantFiled: July 8, 2010Date of Patent: October 6, 2015Assignee: Toyota Jidosha Kabushiki KaishaInventors: Seiho Yonezawa, Koki Ikeda, Shinya Atsumi, Nao Nakagawa

Patent number: 4790279Abstract: An ignition control system for an internal combustion engine which includes a microcomputer which operates to control the ignition timing in response to engine speed and engine temperature signals individually and in preselected combinations with an engine throttle or air flow signal during predetermined engine running conditions. These predetermined running conditions include low speed, warm up, overheat, cruising, and overspeed engine running conditions. The ignition control system is also capable of detecting and responding to abnormal combustion running conditions and setting an optimum spark advance during the starting of the engine.Type: GrantFiled: September 30, 1987Date of Patent: December 13, 1988Assignee: Sanshin Kogyo Kabushiki KaishaInventors: Motoi Tobinaga, Shigeo Okumura, Kenichi Handa, Shinya Atsumi

Patent number: 4759732Abstract: An improved trim tab actuator for a marine propulsion device wherein steering sharpness is improved by providing a pivotally supported trim tab that is steered in response to sensed steering conditions for achieving steering sharpness. In the illustrated embodiment, the steering input force and the steered angle of the outboard drive are measured steered conditions which determine the trim tab position. In addition, certain watercraft conditions such as speed and trim are further measured and determine the optimum trim tab position.Type: GrantFiled: April 1, 1987Date of Patent: July 26, 1988Assignee: Sanshin Kogyo Kabushiki KaishaInventor: Shinya Atsumi

Patent number: 4551104Abstract: A tilt locking and shock absorbing arrangement for a marine outboard drive embodying a single cylinder and piston assembly for controlling the tilt and trim positions of the drive and for further absorbing shocks applied to it. An arrangement is provided whereby the trim position may be manually controlled without necessitating the operator's use of one hand to operate the mechanism when the desired position is reached. Popping up action is permitted in either normal or shallow water conditions but inadvertent popping up under shallow water, reverse drive is precluded.Type: GrantFiled: February 21, 1984Date of Patent: November 5, 1985Assignee: Sanshin Kogyo Kabushiki KaishaInventors: Takashi Iwashita, Shinya Atsumi, Ryoji Nakahama
