  • Publication number: 20150214007
    Abstract: In an ion implantation apparatus, an interruption member interrupts an ion beam B in the middle of a beam line. A plasma shower device is provided at the downstream side of the interruption member in the beam line. A control unit causes the interruption member to interrupt the ion beam B during an ignition start period of the plasma shower device. The interruption member may be provided at the upstream side of at least one high-voltage electric field type electrode in the beam line. A gas supply unit may supply a source gas to the plasma shower device. The control unit may start the supply of the source gas from the gas supply unit after the ion beam B is interrupted by the interruption member.

  • Patent number: 7208856
    Abstract: Claw-shaped magnetic poles are alternately disposed along the rotation plane of a rotor of an electric rotating machine, and a permanent magnet is disposed between the claw-shaped magnetic poles. Surface of the permanent magnet is coated with a coating layer. The coating layer is composed of a anticorrosive material performing sacrificial anticorrosion (metal flake in a coating film rusts prior to a matrix resulting in protection of the matrix) such as inorganic material containing zinc and a film of the anticorrosive material is formed by spraying. Ionization tendency of zinc is larger than that of iron composing the permanent magnet, and the permanent magnet is difficult to be rusted owing to the sacrificial anticorrosion. Consequently, anticorrosion of the permanent magnet disposed between the claw-shaped magnetic poles is improved.

  • Publication number: 20060173088
    Abstract: A method for efficient production of a water-soluble porous polymer and a water-soluble porous polymer excelling in solubility in water are provided. A method for the production of the polymer is characterized by the fact that an aqueous monomer solution containing an ethylenically unsaturated monomer is polymerized while it is containing bubbles therein. The method can simplify the drying and crushing steps and the water-soluble porous polymer consequently obtained excels in solubility in water.
