Abstract: PURPOSE:To prevent the breakage of a portion of a housing due to the vibration of an engine by placing a needle axis in a plane perpendicular to the longitudinal axis of the engine and placing an actuator in a specific direction with respect to the needle axis. CONSTITUTION:The command axis of the needle 7 and plunger 12 of a unit injector 54 is placed in a plane Y perpendicular to a longitudinal axis X. A line Z connecting the common axis of the needle 7 and plunger 12 to a piezoelectric element 32, or an actuator or a piezoelectric element housing 31 extends in an oblique direction with respect to the plane Y. Thereby, the distance between the piezoelectric element housing 31 and the axis of the needle 7 which is measured along the plane Y is reduced, weakening a bending moment which acts repeatedly on a housing portion 1a which extends from around the axis of the needle 7 toward the piezoelectric element housing 31.

Abstract: PURPOSE: To enable to twist continuous fiber bundle by a method wherein a resin impregnating tank is rotated at the desired winding position of a molding tool.
CONSTITUTION: A bobbin 2, onto which continuous fiber bundle is wound, is attached in a resin impregnating tank 1, which can be rotated by means of a rotating shaft 4 installed on a rotating table 3. The continuous fiber bundle is drawn out of the liquid resin 6 in the resin impregnating tank 1, squeezed through a die 7 and wound onto a take-up unit. During manufacturing a structural body, when the fiber bundle 5 reaches a hook 9', the rotation of a main column 8 is stopped and at the same time the resin impregnating tank 1 is rotated by means of the rotating shaft 4, resulting in twisting the fiber bundle 5. Due to the twisting of the fiber bundle through the rotation of the whole resin impregnating tank, the twisting operation can be performed very easily.

Abstract: PURPOSE: To obtain a fibrous resin-structural material which is superior in mechanical characteristics, by a method wherein a structural material is formed by taking up a continuous long fiber impregnated with resin and heating and curing are made to perform after a jig has been made to revolve.
CONSTITUTION: As for a continuous long fiber and synthetic resin which is made to impregnate into the fiber, articles to be used normally for an FRP (fiber-reinforced resin) product are used. A continuous high tensile glass fiber, for example, which has been made to impregnate with unsaturated polyester resin is taken up on a take-up jig 1 and a three dimensional structural material 2 is formed. The take-up jig 1 is fitted to a rotating shaft 4 of a centrifugal separator 3 and made to rotate in the direction of an arrow. The resin removed from the structural material 2 through centrifugal force is recovered through an unloading outlet 5 for reuse. Then the structural material 2 is made to heat and cure with a heating device. Mechanical characteristics of the product is improved as the excessive resin is removed from the structural material formed on the take-up jig through centrifugal force, it does not happen that the fiber is damaged or made to break and as the fibers are filled far thicker and voids which have been contained among fibers are reduced.

Abstract: PURPOSE:To obtain a light-weight steering wheel having practically sufficient tortional rigidity by applying in advance a tortional force in the same direction as external force to one-way oriented fibers. CONSTITUTION:A rotary tool 9 is turned to rotate a winding tool 5 in the direction of arrow, and fibers 2 impregnated with a resin are wound around the tool 5 once. Afterwards, the fibers 2 are wound around a boss tool 11 through notches 8. The processes are repeated to laminate a given number of fibers 2 to form a core material 1. After lamination, the tool 9 is removed out, the boss metal tool 11 is turned, and the fibers 2 in the spoke portion 4 are twisted toward one direction which coincides with the direction of distorting the spoke portion 4 by external force, where the left and right sides are in the opposite directions. The core material 1 is heated to harden the resin in such a way as to prevent the restoration of twist, the metal tool 11 is fixed, and the core material 1 is covered with resin and molded at a give temperature and under a given pressure to obtain a product. By adding the twisting' process, the tortional rigidity of the core material can be raised, enabling it to overcome tortional torque to be generated by external forces.
