Abstract: A cargo handling control unit of a forklift includes a traveling device including a traveling drive unit, forks loading cargos, and a cargo handling device having a lift cylinder. The cargo handling control unit includes at least a pair of one-dimensional laser distance sensors, each of which is configured to emit a one-dimensional laser beam and receives the laser beam reflected from an object, thereby detecting a distance between the object and the one-dimensional laser distance sensor, a picking start position determination unit determining a picking start position of the forks for the cargos, and a picking control unit being configured to control the traveling drive unit and the lift cylinder so as to load the cargos on the forks.

Abstract: There is provided a process for producing a tube member made of fiber-reinforced resin in which it is unnecessary to fold back an end portion of a fiber layer impregnated with uncured resin, and which is capable of joining a tube member, which comprises a resin fiber, and a flanged tube material, which is to be directly rigidly coupled with an engine box or the like, while maintaining the fiber orientation in the initial orientation posture and through an extremely simple process as well. In the process, there is provided a base member 10 comprising a mandrel 1, and an end portion attachment member 2 that is attached to one end thereof and that has a protrusion and a wide diameter portion of a wider diameter as compared to the mandrel. A fiber impregnated with uncured resin is hoop wound around the outer circumference of the mandrel 1 to form a first wound layer 3. A fiber is further helically wound around the outer circumference thereof to form a second wound layer 4.

Abstract: A fiber reinforced plastic propeller shaft has a fiber reinforced plastic pipe, and at least one metal member attached to an end of the pipe. The metal member is provided with a serration having a plurality of teeth having an apex angle. When the metal member is attached to the end of the pipe, each tooth forms on the inner surface of the pipe end a groove extending along the axial direction of the pipe. The apex angle of each tooth is between 45° and 75°.

Abstract: A yoke is secured to the inner surface of an FRP pipe. The yoke has a first end and a coupling portion is located on the first end. The coupling portion has a peripheral surface and is secured to the inner surface of the pipe. A serration is formed on the peripheral surface of the coupling portion. The serration has teeth that can form grooves, which axially extend along the inner surface of the pipe when securing the yoke to the pipe. Recesses are continuously formed on the vertex of each tooth in the longitudinal direction.

Abstract: A step portion is provided between a serration portion of a metal-made yoke and a leading end portion thereof. During pressure insertion and joining, an FRP-made cylinder is pressure-inserted to the serration portion in a state that the circularity is enhanced by the step portion. Consequently, the pressure insertion and joining is carried out while making the depth of cut grooves uniform, thereby enhancing concentricity (joining accuracy).
