Patent number: 6808465Abstract: In a V-belt type transmission having a V-belt entrained on a pulley, the pulley includes a fixed pulley half fixed to an end portion of a crankshaft and a movable pulley half supported on the crankshaft but axially slidable in opposition to the fixed pulley half. The fixed pulley half is secured with a bolt that is threaded and engaged with a female screw formed inside an end portion of the crankshaft. The V-belt type transmission is capable of securely clamping a fixed pulley half and is capable of preventing the entry of dust and water into a fixed pulley half threaded portion formed in an end portion of the crankshaft. This arrangement protects against the formation of rust and corrosion.Type: GrantFiled: April 6, 2001Date of Patent: October 26, 2004Assignee: Honda Giken Kogyo Kabushiki KaishaInventors: Shinji Kuga, Takashi Ohyama, Ryuji Tsuchiya

Patent number: 6554104Abstract: A lubrication structure for an internal combustion engine including an oil pump provided at a first end of an oil pump shaft arranged parallel to a crankshaft. Oil passageways are formed from a side surface of a pump chamber of the oil pump to another end of the oil pump shaft in parallel with the oil pump shaft. An oil filter is provided facing towards the oil passageways. A communicating passageway extending vertically from the oil passageways to the oil filter is also provided. This arrangement provides a lubrication structure for an internal combustion engine with a high degree of freedom with respect to oil filter arrangement with a simple oil passageway that is easy to manufacture, requires relatively small space for arrangement, and thus makes it possible to reduce the size of the internal combustion engine.Type: GrantFiled: March 30, 2001Date of Patent: April 29, 2003Assignee: Honda Giken Kogyo Kabushiki KaishaInventors: Takashi Ohyama, Shinji Kuga, Ryuji Tsuchiya

Patent number: 6547024Abstract: A motorcycle includes an engine mounted on a frame in a non-swingable manner. First and second rear arms are swingably supported by the engine about first and second coaxial swing axes, respectively. A rear wheel is rotatably supported between the first and second rear arms. The second rear arm includes front and rear arm members, which are supported swingably by the engine and support an axle of the rear wheel, respectively. The arm members are separably connected together to facilitate servicing and removal of the rear wheel.Type: GrantFiled: September 6, 2001Date of Patent: April 15, 2003Assignee: Honda Giken Kogyo Kabushiki KaishaInventors: Takashi Ohyama, Chikashi Iizuka, Shinji Kuga

Patent number: 6544134Abstract: A belt type transmission improves the durability of a support portion of a driven shaft by reducing a load acting on a driven shaft, and improves the durability of the belt and reduces noise by suppressing vibration of a driven pulley. The belt type transmission includes a driven pulley having a fixed pulley piece and a movable pulley piece fitted to a driven shaft. The fixed pulley piece is rotatably supported, respectively, on the driven shaft and a bearing holder, being a constructional element of a transmission case. The bearing holder has a size overlapping only the driven pulley, and is coupled to a left case, which is a constructional element of the transmission case, in the vicinity of the driven pulley. As a result, the rigidity for supporting the fixed pulley piece on the driven side can be increased, thereby enabling suppression of vibration by the driven pulley.Type: GrantFiled: March 30, 2001Date of Patent: April 8, 2003Assignee: Honda Giken Kogyo Kabushiki KaishaInventors: Takashi Ohyama, Shinji Kuga, Tetsuaki Maeda

Publication number: 20020075272Abstract: The display RAM built into a conventional display control device uses a system in which data are sequentially written word by word, it involves a problem that, if th write speed is to be raised to match the transfer speed of display data from the microprocessor, the power consumption will increase in proportion to the transfer speed. The width (number of bits) of write data to a display RAM in a display control device is set to be an integral multiple of the width of write data supplied from an external microprocessor or the like, and two stages of latch circuits for holding write data equivalent to one row of the display RAM are provided.Type: ApplicationFiled: December 3, 2001Publication date: June 20, 2002Applicant: Hitachi, Ltd.Inventors: Kunihiko Tani, Yoshikazu Yokota, Goro Sakamaki, Takashi Ohyama

Patent number: 6397810Abstract: To provide a balancer-fitting configuration for an internal combustion engine. With the balancer-fitting configuration of the present invention, the vibration control of an internal combustion engine with forward-inclined cylinders is achieved effectively by using paired balancers separated and disposed opposite to each other. Furthermore, the part of the crankcase behind the crankshaft is decreased in size in the longitudinal direction of the frame, and thereby, a space within which the rear wheel swings is obtained without enlarging the frame.Type: GrantFiled: February 22, 2001Date of Patent: June 4, 2002Assignee: Honda Giken Kogyo Kabushiki KaishaInventors: Takashi Ohyama, Shinji Kuga, Ryuji Tsuchiya, Tetsuaki Maeda
