  • Patent number: 8657593
    Abstract: The present invention is aimed at providing a sintered magnet production system that can prevent the influences of a leaking magnetic field in an orienting process. A sintered magnet production system according to the present invention has a filling means 11 for filling an alloy powder into a filling/sintering container, a sintering means 13 for sintering the alloy powder, and an orienting means 12 with an air-core coil for producing a magnetic field for orienting the alloy powder in the filling/sintering container after the filling process and before the sintering process, the axis of the air-core coil being displaced from a straight line connecting the filling means 11 and the sintering means 13. The magnetic field leaking from the orienting means 12 is strongest on the extended line of the axis of the air-core coil and relatively weak in the direction perpendicular to the extended line.

  • Publication number: 20130337265
    Abstract: A method of modifying a thermoplastic polymer powder. A suspension of thermoplastic polymer powder and reinforcement elements in a liquid is heated within a reaction chamber so that the thermoplastic polymer powder becomes softened and the reinforcement elements migrate into the softened thermoplastic polymer powder to form modified thermoplastic polymer powder. The modified thermoplastic polymer powder is then separated from the liquid. The reinforcement elements have an electromagnetic moment and are subjected to an electromagnetic field as the suspension is heated. The interaction of the electromagnetic field with the electromagnetic moment of the reinforcement elements causes the reinforcement elements to become aligned with the electromagnetic field before they migrate into the powder.
