  • Patent number: 6619147
    Abstract: A linear actuator comprises a motor, a rotation-to-linear motion conversion mechanism having a screw and a nut, a support block supporting an end of the screw, and an actuator-side support member with a swing support mechanism (e.g., a swing axis or bearing portion in case of a Trunnion mechanism, or a swing support bearing portion or support leg of the swing support bearing portion). The actuator-side support member is part of the support block or an extension member of the support block or connected therewith. The swing axis of the swing support mechanism is located in the plane including the screw axis, and the force flow line inside the linear actuator is limited on the output shaft, the nut, the screw and the support block.

  • Patent number: 6015953
    Abstract: An end of a conductor having a stranded conductor layer wound around a tension member made of resin-reinforced carbon fiber is cut back to expose the end of the tension member. The exposed end of the tension member is inserted into a metal fitting having multiple longitudinal slits. A metal sleeve is then fit over the metal fitting and also partially over the stranded conductor layer before compress-fitted into place. Accordingly, it is possible to attach, with good workability and sufficient tensile strength, a conductor that has a tension member made of resin-reinforced carbon fiber.

  • Patent number: 5287072
    Abstract: A semiconductor device comprises a plurality of gate electrodes, drain electrodes, and source electrodes axi-symmetrically formed on opposite sides of a gate pad and drain pad. Two source pads are arranged at ends of these electrodes, to which the source electrodes are connected, so that a gate width can be shortened. Therefore, an output power, gain, etc., can be increased, and the high-frequency characteristics can be improved. Further, when arranging a plurality of semiconductor devices in parallel, the semiconductor chip can be formed in the shape of a square, i.e., the aspect ratio thereof can be reduced, and therefore, cracks in the semiconductor chip (semiconductor device) can be avoided.

  • Patent number: 5207847
    Abstract: A pneumatic tire of a low profile is disclosed which is constructed with a a cap tread, a sidewall and a tie rubber interposed therebetween. The cap tread is formed from a rubber composition comprised of a styrene-butadiene rubber of a high styrene content. The tie rubber comprises a specified sum of a syndiotatic-1,2-butadiene rubber and a cis-1,4-butadiene rubber. Use of the tie rubber is conductive to sufficient adhesion of the tread to the sidewall without shoulder blistering after vulcanization.

  • Patent number: 4066001
    Abstract: A skiving cutter for use in cutting an internal spur gear having a cutter body adapted to be mounted on a spindle extending from a cutter head. Cutting blades are formed thereon at a position offset from the intersection of the axis of the cutter and the axis of a work piece to be cut. Further, the contacting point between each cutting blade of the cutter and each gear tooth formed on the work piece is located within a contacting or acting region therebetween. Thus, the design value of the blade profile of the cutter may be selected to be near the lower limit of the contacting or acting region.

  • Patent number: 3931754
    Abstract: A skiving cutter device for use in cutting an internal spur gear having rough and finish skiving cutters with cutter blades mounted in vertical arrangement on a spindle and spacers adapted to compensate respective distances between the cutters and a reference plane on the spindle. Respective cutter blades of the cutters are located in the same phase and each tooth profile thereof is designed such that the contacting point between each cutter blade of the cutters and each gear tooth of an internal spur gear to be obtained is located within a contacting or acting rejion therebetween. The device is further provided with spiral key ways respectively formed in the cutters and pin keys set up on the spindle and engaged with the key ways, respectively.
