  • Patent number: 9935531
    Abstract: A manufacturing method for a laminated rotor includes inserting a bridge member into a magnetic flux leakage suppression hole, thus allowing a tip of the bridge member to project from an end surface of the laminated steel sheet, and bringing a die surface of a die member into pressure contact with an end surface of the laminated steel sheet and filling a molten resin into a gap between a magnet hole and a magnet body in a state where an opening of the magnet hole is closed. A length of the bridge member is larger than a thickness of the laminated steel sheet. The die member includes a housing portion. The housing portion houses the tip of the bridge member projecting from an end surface of the laminated steel sheet.

  • Patent number: 8979690
    Abstract: A toothed belt has therein a core wire (3) including a core thread (1) made of aramid fiber and a filament thread (2) made of nylon fiber, and has belt tooth portions (4) and belt groove portions (5) alternately formed therealong. The core wire (3), the belt tooth portions (4), and the belt groove portions (5) are integrated with one another by a rubber material (7). It should be noted herein that the core thread (1) and the filament thread (2) are integrally twined around each other so that the filament thread (2) is formed in the shape of a plurality of loops around the core thread (1). The filament thread (2) in the shape of the loops enters tooth root portions (9) of the belt tooth portions (4) to be arranged therein. As a result, the tooth root portions (9) are strengthened.
