Patent number: 10160506Abstract: To suppress intake noise and secure a quiet ride on a straddle type vehicle wherein a box-shaped structure includes an air cleaner box connected to an engine. In addition, exhaust air from the radiator disposed in the vicinity of the box-shaped structure is prevented from hitting a leg portion of a rider. A main frame is provided as a separate body from a head box so as to support a power unit and a front two-wheeled suspension device. The head box is supported on the main frame due to the fact that an air cleaner box is fixed on the main frame through a fixing member. A guide portion is formed on the air cleaner box so as to guide the exhaust wind from a radiator to the lower direction.Type: GrantFiled: August 12, 2016Date of Patent: December 25, 2018Assignee: HONDA MOTOR CO., LTD.Inventor: Yuichi Yokoyama

Patent number: 9746802Abstract: An image forming apparatus according to an embodiment includes a first image forming unit that forms a transparent toner image and a second image forming unit that forms a color toner image. The transparent toner image and the color toner image are transferred onto an intermediate transfer belt. A secondary transfer unit transfers the toner images from the intermediate transfer belt to a recording medium. A control unit controls the first image forming unit and the second image forming unit so that the transparent toner image is formed before the color toner image is formed when the recording medium is a specialty paper having an adhesive.Type: GrantFiled: August 4, 2016Date of Patent: August 29, 2017Assignees: KABUSHIKI KAISHA TOSHIBA, TOSHIBA TEC KABUSHIKI KAISHAInventor: Yuichi Yokoyama

Patent number: 9586641Abstract: A step structure of a saddle-ride type vehicle is configured to permit easy adjustment of a position and also of an angle of a step. A pair of opposed clamp pieces, that are formed as part of a step-support bracket provided to a vehicle body of a saddle-ride vehicle, are provided to sandwich an eccentric collar (rotor) from both sides thereof in a radial direction. The clamp pieces are configured to be tightened against the eccentric collar by a bolt, thereby non-rotatably fixing a position of the eccentric collar. The eccentric collar is configured such that when the clamp pieces are loosened, a shaft part of a step is pivotally movable in relation to a shaft insertion hole, and the step, supported by the shaft insertion part, can be adjustably rotated in relation to the step-support bracket.Type: GrantFiled: July 23, 2015Date of Patent: March 7, 2017Assignee: Honda Motor Co., Ltd.Inventors: Yuichi Yokoyama, Tetsuya Nakazawa
