Abstract: An electric-powered vehicle includes: an axle body that includes an axle and drive wheels connected to both ends of the axle; a magnetic geared motor for rotating the axle, the magnetic geared motor including a stator, a low-speed rotor, and a high-speed rotor; a vehicle structure supported by the axle body; a motor support for connecting the vehicle structure and the stator, and supporting the magnetic geared motor by the vehicle structure; and an elastic coupling for coupling the low-speed rotor and the axle such that a rotational force of the low-speed rotor is transmittable to the axle.

Abstract: The injection molding apparatus of the present invention includes: a heating cylinder; a screw that is provided rotatably in an inner portion of the heating cylinder; a resin feed hopper that feeds a resin pellet; and a fiber feed device that is provided ahead of the resin feed hopper and feeds reinforcing fibers into the heating cylinder. The screw includes a first stage that is located on a rear side, and in which the resin pellet is melted, and a second stage that is located on a front side, and in which the melted resin pellet and the reinforcing fibers are mixed, and a lead of a second flight provided in the second stage is larger than a lead of a first flight provided in the first stage.

Abstract: The present invention provides an AC motor controller for a battery forklift operated by driving an AC motor via a three-phase bridge inverter using a battery as an energy source, wherein it is possible to replace only a damaged arm, and the control signal of each arm is isolated with a transformerless constitution, by using a diode. The AC motor controller comprises the three-phase bridge inverter containing three arms having semiconductor elements connected in series on their positive side and negative side, wherein the three arms, each of which constitutes a mounting unit, form a module, and each of the three arms is independently removable.
