Publication number: 20040159178Abstract: A split type connecting rod has a simple structure that is capable of suppressing rotation of a metal bearing, and avoiding problems such as burning. The split type connecting rod 200 holds a crank-pin through a metal bearing 213 which has locking lugs 213c, 213d. A bearing locking groove 201h locks at least one of the locking lugs 213d when the metal bearing 213 rotates forward in the circumferential direction of a crank-pin hole 101d. A bearing locking groove 201i locks at least one of the locking lugs 213c when the metal bearing 213 rotates backward. The bearing locking grooves 201h, 201i are deviated from each other in the circumferential direction.Type: ApplicationFiled: December 23, 2003Publication date: August 19, 2004Inventors: Akitoshi Nakajima, Satoshi Kikuchi, Tsuyoshi Kubota, Tsuneo Isobe, Shinya Iwasaki

Publication number: 20040025340Abstract: A connecting rod is formed using a method that comprising providing a connecting rod blank having. The connecting rod blank has a rod section disposed between a big end and a small end. The big end has a first hole generally sized to receive a crankpin of a crankshaft and at least one second hole generally sized to receive a bolt, wherein the axes of the first and second holes are generally normal to each other. The big end of the connecting rod has a dividing plane that extends through both the first and second holes. The connecting rod blank is processed by hardening at least the big end to a sufficient depth such that a first region of the big end lying between the first and second holes at the dividing plane is hardened, while leaving a substantial second region of the big end at the dividing plane generally unhardened. The connecting rod blank is further processed by splitting the big end along the dividing plane to produce a rod part fracture surface and a cap part fracture surface.Type: ApplicationFiled: July 16, 2003Publication date: February 12, 2004Inventors: Tsuyoshi Kubota, Shinya Iwasaki, Tsuneo Isobe

Patent number: 6679637Abstract: An printing apparatus is equipped with a recording medium transport device for transporting a recording medium from a supply portion along a transport path; at least one printing device arranged on the transport path for selectively forming an image on the recording medium or an intermediate transfer medium for temporarily holding the image at a predetermined image forming position; and a transfer device arranged on the transport path for transferring the image formed on the intermediate transfer medium to the recording medium. A mode setting device selects a mode between the first mode in which the printing device forms the image on the recording medium and the second mode in which the printing device forms the image on the intermediate transfer medium. An intermediate transfer medium moving device advances and retracts the intermediate transfer medium between the image forming position and a retracted position.Type: GrantFiled: July 30, 2002Date of Patent: January 20, 2004Assignee: Nisca CorporationInventors: Wataru Tsuruta, Tsuyoshi Kubota

Patent number: 6668716Abstract: A printing apparatus includes a card transport path composed of the first card transport path for forming an image to a card using a direct transfer method, and the second card transport path composed of a card transport path for transferring an image from an intermediate transfer sheet to the card. An image forming portion is arranged on the first card transport path for forming the image on the card or the intermediate transfer sheet. A transfer portion is arranged to the second card transport path for transferring the image from the intermediate transfer sheet to the card. The first card transport path and the second card transport path intersect while the printing apparatus can switch between the direct transfer method and the indirect transfer method.Type: GrantFiled: May 31, 2002Date of Patent: December 30, 2003Assignee: Nisca CorporationInventors: Wataru Tsuruta, Tsuyoshi Kubota

Publication number: 20030089166Abstract: An all-terrain vehicle having at least one front wheel and a handlebar assembly. A steering column extending from the handlebar assembly to the at least one front wheel to turn the front wheel in response to rotation of the handlebar assembly. A torque detection device is configured to detect a torque applied to the steering column. The torque detection device may produce an output signal corresponding with the torque applied to the steering column to be used by a control system, for example, in controlling the output of a steering assist motor. The torque detection device includes a pressure receiving element to which a load is applied during rotation of the steering column. A sensor detects the load applied to the pressure receiving element to permit the torque applied to the steering column to be ascertained.Type: ApplicationFiled: November 12, 2002Publication date: May 15, 2003Inventors: Yutaka Mizuno, Tsuyoshi Kubota
