  • CONNECTION METHOD OF THERMOPLASTIC RESIN LONG BODY
    Publication number: 20110290400
    Abstract: A connection method for interconnecting end portions of a thermoplastic resin long body in which conductive unstretchable members are embedded within the thermoplastic resin along a longitudinal direction, wherein the unstretchable members in each of specific sections in the both end portions of the thermoplastic resin long body are heated using an induction heating portion so that the thermoplastic resin coating the unstretchable members is removed by melting for the unstretchable members to be exposed, after which the both end portions are interconnected while they are held in a state where the unstretchable members being exposed in the respective end portions are butt-connected to each other.
    Type: Application

  • Ring magnet and method of manufacturing the magnet
    Patent number: 7551051
    Abstract: Radially oriented ring-shaped preliminarily molded pieces of a ring magnet are stacked in an axial direction to form a ring-shaped molded body, in which end faces of the ring-shaped preliminarily molded pieces are bonded together. This ring-shaped molded body is sintered and heat-treated to produce the ring magnet. Ring magnets which are less susceptible to deterioration of magnetic properties due to a disturbance of magnetic orientation near lamination boundary surfaces are produced. The invention provides a method of manufacturing such ring magnets with high efficiency.
