Patent number: 6758111Abstract: A continuously variable transmission comprising a lay shaft that rotates in response to the input power from the engine. A crank on the lay shaft and a drive rod translate the rotation of the lay shaft into linear motion. An output rod rotatably mounted at a transmission shaft translates the linear motion of the drive rod into rotational motion.

Patent number: 6758138Abstract: A stencil is made by thermally forming perforations arranged in both a main scanning direction and a sub-scanning direction in a thermoplastic resin film of heat-sensitive stencil material by the use of a heat source which is heated through supply of energy. Supply of energy to the heat source is cut when a time interval not shorter than 50% and not longer than 100% of an estimated perforating time lapses from the time at which supply of energy to the heat source is started. The estimated perforating time is a time interval expected to be necessary for a perforation to be produced by the heat of the heat source and to be enlarged to a desired size as a final size as measured from the time at which supply of energy to the heat source is started.Type: GrantFiled: May 30, 2003Date of Patent: July 6, 2004Assignee: Riso Kagaku CorporationInventors: Jun Nakamura, Kenji Ohshima

Patent number: 6758145Abstract: A model railroad track cleaning car having a cleaning element suspended between a pair of wheeled trucks. The cleaning element is an abrasive material that is affixed to the underside of a weighted chassis that is suspended from a pair of articulating arms connected to the respective wheeled trucks. The cleaning material is easily replaced by removing a pair of fasteners from the chassis. A spring tension apparatus is positioned between the articulating arm and the cleaning element chassis to selectively position the cleaning element over the model railroad tracks. A retaining wire is captured in the articulating arm and engages the corresponding truck to turn the articulating arm with the truck, thus positioning the cleaning element over the model railroad tracks even when traversing a curve. A thumb wheel is formed with a notch that receives the articulating arm to lock the thumb wheel into a selected position.Type: GrantFiled: May 5, 2003Date of Patent: July 6, 2004Inventor: Henry Hefter

Patent number: 6758149Abstract: This invention provides a refuse incinerator capable of extinguishing smoke and odor of exhaust gas emitted from, combustion of the refuse just after incineration of the refuse is started. Exhaust gas outlets are provided in a furnace lid of the incineration furnace, an exhaust gas chamber is provided such that the furnace lid is used as part of a bottom wall thereof and an exhaust gas introduction pipe is provided to communicate between the exhaust gas chamber and a combustion chamber. Exhaust gas emitted into the exhaust gas chamber is introduced into the combustion chamber and burnt so as to extinguish the smoke and odor. Because the combustion chamber reaches high temperatures just after the incineration of the refuse is started, the smoke and odor of the exhaust gas are extinguished just after the incineration of the refuse is started.Type: GrantFiled: May 30, 2003Date of Patent: July 6, 2004Assignees: Meito Corporation, MCR Co., Ltd.Inventors: Masatoshi Oiwa, Hideo Hirano, Satoshi Furuta
