Publication number: 20040168513Abstract: A waste-material entry prevention member arranged upstream of a flow sensor is a rod- or plate-like member protruding halfway across the cross-section of a flow passage. Hence, vortexes or energy of the vortexes produced in fluid flowing by the waste-material entry prevention member is diffused by a stream of the fluid passing through a space left between the waste-material entry prevention member and the wall surface of the flow passage which the waste-material entry prevention member faces. Thus, production of vortexes is held down. Further, by making the flow sensor generate heat or heating the flow sensor, thermophoresis of the fluid is caused near the surface of the flow sensor. By this, particles contained in the fluid are prevented from accumulating on the flow sensor.Type: ApplicationFiled: December 23, 2003Publication date: September 2, 2004Applicant: Yamatake CorporationInventors: Shigeru Aoshima, Junichi Matsuda, Isamu Warashina, Yasuharu Ooishi

Publication number: 20040168534Abstract: The invention concerns a gearwheel for a mechanical gearwheel transmission of an automotive vehicle, which gearwheel rotates loosely on a shaft, cylindrical rolling elements (18, 19) being arranged between an inner raceway associated to the shaft and an outer raceway associated to a hub of the gearwheel. According to the invention, the gearwheel (13) is mounted through two spaced apart roller crown rings comprising cylindrical rolling elements (18, 19) and cages (20, 25), projections (21, 26) of the cages (20, 25) engaging into a groove (22) that is arranged in a radially inward pointing center flange (24) between the outer raceways (17). In this way, an inseparable pre-assembled unit made up of the gearwheel (13) and the roller crown rings is formed that facilitates the assembly of the mechanical gearwheel transmission.Type: ApplicationFiled: January 21, 2004Publication date: September 2, 2004Inventor: Manfred Winkler

Publication number: 20040168535Abstract: A window lifter geared motor assembly includes a housing, an electric motor in the housing, a damper damping the movements of the electric motor in the housing, and a drive shaft driven in rotation about an axis by the electric motor. The electric motor and the drive shaft are able to move in the housing along the axis, and the damper damps the movements of the electric motor and the drive shaft along the axis. The assembly further includes a sensor, the state of which is dependent upon the movements of the electric motor and of the drive shaft along the axis. The driving of the drive shaft is preferably dependent upon the state of the sensor and the drive shaft is stopped when an obstacle impedes movement of the window. The damper occupies a position that is immobile with respect to the housing, allowing the damper not to experience movements likely to cause the characteristics of the damper to vary.Type: ApplicationFiled: July 25, 2003Publication date: September 2, 2004Inventor: Gerard Fournier

Publication number: 20040168536Abstract: A system for positioning an object about a remote center of rotation. A non-movable part provides a stationary reference structure. A movable part moves relative to the non-movable part. A connector coupled between the movable part and the object positions the object adjacent the remote center of rotation and rotates it about the remote center of rotation responsive to movement of the movable part. Movement of the connector responds movement of the movable part. First and second force transmitting components coupled to the movable part move the movable part and the connector in first and second directions, respectively. Movement of the connector in the first direction rotates the object about a first axis passing through the remote center of rotation. Movement of the connector in the second direction rotates the object about a second axis passing through the remote center of rotation.Type: ApplicationFiled: December 5, 2003Publication date: September 2, 2004Inventor: Yves Bellouard

Publication number: 20040168537Abstract: A shifter assembly (20) having a base (22) and a transmission control member (30). A shift lever (36) is pivotally connected to the base (22) for movement within a first path (38) and a second path (40). The shift lever (36) is coupled to the control member (30) when the shift lever (36) moves within the first path (38) and is uncoupled from the control member (30) when the shift lever (36) moves within the second path (40). The shifter assembly (20) is characterized by a locking device (80) mounted to the base (22) for selectively engaging the control member (30). The locking device 80 remains stationary during the concurrent movement of the control member (30) and the shift lever (36) and moves into engagement with the control member (30) to couple the control member (30) to the base (22) when the shift lever (36) is in the second path (40).Type: ApplicationFiled: February 28, 2003Publication date: September 2, 2004Applicant: Teleflex IncorporatedInventor: Edward Koontz

Publication number: 20040168538Abstract: A twist-grip for controlling the operation of a bicycle transmission comprises a rotatable member structured to be mounted coaxially around an axis of a bicycle handlebar so that the rotatable member can rotate relative to the handlebar; a grip disposed on the rotatable member so that the rotatable member can be rotated by manipulating the grip; an index finger portion adapted to receive an index finger of a rider; a middle finger portion adapted to receive a middle finger of the rider; and an intermediate portion disposed between the index finger portion and middle finger portion. The intermediate portion has a wave-shaped portion so that the waved-shaped portion can be located between the index and middle fingers of the rider. If desired, the middle finger portion may have an outer diameter less than an outer diameter of the index finger portion.Type: ApplicationFiled: February 28, 2003Publication date: September 2, 2004Applicant: Shimano, Inc.Inventor: Takuji Masui

Publication number: 20040168541Abstract: A flywheel (1) for an internal combustion engine is provided for generating a cooling air flow and is especially for a two-stroke engine on a portable handheld work apparatus such as a motor-driven chain saw, cutoff machine or the like. The flywheel (1) carries a parallelopipedly-shaped permanent magnet (5) for a magnetic ignition system. The permanent magnet has a short edge (6), a center edge (7) and a long edge (8). The permanent magnet (5) is polarized in the direction of the short edge (6). To provide a high moment of inertia of the flywheel (1) while achieving a low weight, the short edge of the permanent magnet (5) runs tangentially to the peripheral direction of the flywheel (1) and that the long edge (8) of the permanent magnet (5) is aligned parallel to the rotational axis (11) of the flywheel (1).Type: ApplicationFiled: February 10, 2004Publication date: September 2, 2004Applicant: Andreas Stihl AG & Co.

Publication number: 20040168542Abstract: A clipless mechanism for a four-sided clipless bicycle pedal is made by a stamping and welding process. The stamping is preferably a progressive stamping process. The stamped parts include two components, an inner wing and an outer wing. The two stamped components are generally similar in shape to each other, but the inner wing fits within the outer wing. Each part is first stamped as a flat pattern by a progressive die. Each part then has radii stamped into the edges by the second station of the progressive die. Next, each part is partially folded by the third station of the progressive die. Then each part is folded completely by the fourth station of the progressive die. The actual number of steps may vary depending upon the material chosen, the thickness of the material and the design of the stamping tool. Then each part is welded closed and the resulting rectangular wings are assemblied in juxtaposed orthogonal relation to provide four shoe cleat engaging receptacles.Type: ApplicationFiled: February 27, 2003Publication date: September 2, 2004Inventors: Frank Hermansen, Carl Winefordner
