  • Maintenance apparatus for medical hand piece
    Patent number: 8439677
    Abstract: The present invention provides a maintenance apparatus for increasing the service life of a medical handpiece. The maintenance apparatus is provided with a first fluid supply which feeds a maintenance fluid to the bearings of a handpiece, capable of rotatably supporting a rotary tool, and a second fluid supply which feeds the maintenance fluid to the chucking structure of the handpiece, capable of detachably holding the rotary tool.
    Type: Grant

  • Arc melting and casting method and apparatus thereof
    Patent number: 4762165
    Abstract: Metal material is melted by moving the magnetic flux of electromagnets virtually perpendicular to an arc column to apply Lorentz force to the arc column and the metal material so that the arc column can move over the metal material surface. The movement direction and speed of the arc column are determined by detecting the arc voltage of the arc column. Feed back control is performed by comparing the obtained detection data with preset data so that optimum control is performed, and the molten metal is poured into a casting mold.
