Abstract: A vehicle steering apparatus is configured to apply, to a steered wheel of a vehicle, a driving force for canceling a toe change amount caused by a road irregularity. The vehicle steering apparatus includes a road reaction force detector configured to detect a road reaction force received by a tire of the steered wheel, a toe adjustment actuator coupled to the steered wheel, and a controller configured to control a driving force of the toe adjustment actuator. The controller includes a toe change amount setter configured to set the toe change amount based on the road reaction force detected by the road reaction force detector, an operation amount calculator configured to calculate an actuator operation amount for canceling the toe change amount set by the toe change amount setter, and a driver configured to drive the toe adjustment actuator by the actuator operation amount calculated by the operation amount calculator.

Abstract: A front-rear wheel driving force distribution device includes a center differential and a limited slip differential. The limited slip differential includes a first clutch, a second clutch, a first piston, a second piston, and a one-way clutch provided between the first clutch and a rear propeller shaft. If the second clutch is engaged by the second piston, the propeller shaft on the rear side rotates at increased speed as compared with a case where the first clutch is engaged by the first piston. The one-way clutch couples the first clutch and the rear propeller shaft if a number of rotations of the first clutch is same as or higher than a number of rotations of the rear propeller shaft, and idles if the number of rotations of the first clutch is lower than the number of rotations of the rear propeller shaft.

Abstract: In a tumbler and the like, polypropylene pellets are blended with 1 to 5 wt % of carbon nanotubes, 10 to 30 wt % of fly ash, 10 to 20 wt % of talc and 0.3 to 1 wt % of a modifier, the resulting blend is extruded from a screw extruder while heating the blend to a melting temperature of about 160 to 260° C., to generate a strand. This strand is cooled and cut into pellets having a predetermined length. Owing to blending with fly ash, talc and a modifier, an inexpensive lightweight electroconductive thermoplastic resin excellent in dust-proofness, heat resistance and recyclability is obtained, even if the blending amount of carbon nanotubes is small.

Abstract: An object of the present invention is to provide a straw tube capable of preventing reduction of pressure inside a drinking container when sucked, an apparatus, and a method for producing the straw tube and for using the apparatus. A straw tube has a tube body having a plurality of grooves extending in the longitudinal direction and a convex streak sandwiched by these grooves and projecting outward from the datum level of the outer circumferential wall. An apparatus has a rotating drum having tube loading grooves, a female rod having grooves and capable of reciprocating within the tube loading grooves by a cam mechanism, and a male roller having convex streaks corresponding to the grooves of the female rod so that the grooves of the female rod engage with the convex streaks through the tube and the female rod and the male roller are synchronized.
