  • Patent number: 7170209
    Abstract: A rotor for a reluctance type rotating machine includes a rotor core formed by stacking a number of annular core materials each of which includes magnetic concave and convex portions. The rotor core has two keys which are formed at two positions on an inner circumference of the rotor core. The positions are spaced 180 degrees apart from each other with respect to the rotor core. The rotor core is divided into a plurality of blocks and the core materials constituting at least one block have the magnetic concave and convex portions shifted by a predetermined angle relative to the core materials constituting the other or another block on the basis of a center line passing through the keys. A whole or part of the core materials of at least one block are located circumferentially 180 degrees apart form the core materials constituting the other or another block.

  • Patent number: 6395342
    Abstract: The invention relates to a process of preparing pellets of a synthetic organic fiber reinforced polyolefin and discloses the process in which the reinforcing fiber is impregnated with the molten polyolefin. The invention is characterized in that the sufficient impregnation can be carried out by selecting the polyolefin and the synthetic organic fiber having the appropriate melting points and controlling the temperature of the molten polyolefin to minimize the heat deterioration of the synthetic organic fiber. The pellets obtained by the process of the invention provides a molded product having superior impact resistance and recyclability when used as raw materials for injection molding, injection-compression molding, extrusion, blow molding and a like molding process.
