    摘要: The method of forming a light-weight, fiber-reinforced, particularly glass fiber-reinforced-thermoplastic resin product includes the steps of melting and mixing thermoplastic resin pellets containing parallely oriented fibers 2-100 mm long, injecting the melted resin into a cavity which is closed so that its volume is smaller than that of the final molded product, and, before or after the resin injection is completed, opening the cavity until its volume is equal to that of the final molded product. Unlike the conventional injection-molded products, this product does not require a foaming agent and, if it uses any, requires only a small amount of foaming agent. The product thus formed is light in weight and has fibers uniformly entangled inside, providing an excellent appearance of the surface. Further a skin layer is formed over the surface. These features combined with the reinforcement by the glass fibers offer high strength and high stiffness.

    摘要: A temperature sensor (33) detects the temperature of a MOS transistor (7), and a current detecting circuit (35) detects current flowing in the MOS transistor (7). When the voltage corresponding to the detected temperature or the voltage corresponding to the detected current is increased to a threshold value or more, an overheat state detecting signal and further switching signal is set to a high level. As a result, a switch circuit in a driving circuit (17) is turned on, and the gate resistance value becomes the parallel value of a resistor (25), and the PWM frequency in the PWM control circuit is lowered, whereby the switching loss of the MOS transistor (7) can be reduced under the state that the motor (2) is rotated.

    摘要: Using a mold equipped with a rib-forming member capable of moving forward and backward relative to the mold cavity, produced is a lightweight, hollow resin molding having a reinforcing rib structure in the hollow area, from a fiber-containing thermoplastic resin having a fiber content of from 10 to 70% by weight. To produce the molding, a melt of a fiber-containing thermoplastic resin is injected into the mold cavity or is injected thereinto under compression, then the movable mold member is moved backward in the direction in which the mold cavity is expandable, and after the start of the mold member moving, a gas is introduced into the resin melt. Even though the molding has a hollow structure and has a large surface area, it has good stiffness and high strength, and has good appearances. The weight of the molding can be well controlled and reduced to any desired degree. The molding has many applications in various fields.
