Abstract: PROBLEM TO BE SOLVED: To prevent a displacement member form colliding with a stopper by controlling the target steering angle of a steering wheel in such a manner that the absolute value of the target steering angle of the steering wheel is equal to or less than the maximum steering angle of the steering wheel. SOLUTION: An input angle sensor 2 detects an input angle θh corresponding to the rotation of a steering wheel 1. An output angle sensor 4 detects an output angle θp corresponding to the rotation of a motor 12. A car speed sensor 6 detects a car speed (v). A controller 7 generates a control signal for a motor 12 of a variable gear ratio actuator 3 according to the input angle θh and the output angle θp . With the rotation of the motor 12, the displacement member of the steering wheel steering mechanism 5 is shifted right and left, thereby steering the steering wheels FW1, FW2. The target steering angle of the steering wheel is controlled by the controller 7 in such a manner that the absolute value of the target steering angel of the steering wheel is equal to or less than the maximum steering angle. Thus, the collision of the displacement member is prevented.

Abstract: PURPOSE:To simplify a sensor mounting structure on nozzle holder, improve working efficiency in assembling the sensor therein and prevent lead wires from breaking, in a two stage opening type fuel injection valve. CONSTITUTION:A first spring chamber 1 and a second spring chamber 34 which are connected to each other at a step 36 are engraved in a nozzle holder 12. A groove 40 which extends from the opening end of the second spring chamber 34 to the first spring chamber through the step 36 is formed along the axial direction of the second spring chamber 34. A sensor disk 60 is inserted into the second spring chamber 34, and the head section 58a of a pin 58 fitted in the pin hole 56 of the sensor disk 60 is fitted in the groove 40. Therefore, the sensor disk 60 in which the pin 58 is fitted can move along the groove 40, but can not make any turning movement in the direction for intersecting the groove 40. This constitution restricts the variation of the relative position in the peripheral direction of the sensor disk 60 and the nozzle holder 12.

Abstract: PURPOSE:To enable to obtain a steering wheel core material with sufficient torsional rigidity by a method wherein the rotating shaft of a take up unit is directed in nearly the same direction as the direction, in which fiber bundle is supplied. CONSTITUTION:In order to form a steering wheel core material, the spoke parts 8 are formed by winding resin-impregnated fiber bundle 5 from one notched part 7 of a take-up jig 1 to a boss piece 4 while laminating a ring part 6. At that time, before winding the bundle to the boss piece, a rotating shaft 3 is turned by 90 deg. so as to direct the rotating shaft 3 in the same direction as the direction, in which the fiber bundle 5 is supplied in order to twist the fiber bundle 5. After the fiber bundle 5 is twisted in the above-mentioned manners, the rotating shaft 3 is again returned to its original direction to form the spoke part 8. By repeating the operation as mentioned above, the steering wheel core material made of fiber bundle, to the spoke part of which twisting is applied, is laminated.

Abstract: PURPOSE:To produce the reinforced plastic structure excellent in the characteristics of uniformity and strength, etc. at high productivity by applying ultrasonic vibration to the bundle of continuous fiber being impregnated with resin. CONSTITUTION:When the bundle 2 of continuous fibers passes through the inside of resin 8 in a coating tank, the ultrasonic vibration from an ultrasonic vibrator 10 is applied onto the bundle together with the resin 8. Consequently, the wetting property of the continuous fiber to the resin 8 is improved and the bubbles having been mixed in the bundle 2 at its dipping are raised smoothly by its buoyancy and removed in open air. Therefore, the structured article 13 formed with a resin impregnated fiber bundle 14 has almost no bubble, large fiber amount (Vf) and a uniform and fine structure with high strength. Because the continuous fiber is caused to have specially good wetting property to the resin 8 by ultrasonic vibration, the bundle 2 of the continuous fiber is easily impregnated with the resin 8.
