Title: Abrasive disc paper
Inventor: YASUDA HIROAKI
IPC: B24D11/00
Filed: 1986-10-21
Abstract: PURPOSE:To check generation of heat at the time of grinding to the utmost as well as to eliminate any deformation in an outer palte, by making some concave grooves installed in an inner circumferential aprt from the center appear on the surface of a superposed abrasive. CONSTITUTION:In polishing operations, an abrasive surface 5 of disc paper 1 grinding an outer plate with circular rotation peels a paint film with proper surface contact by concave groove 3 radially installed in the surface of an abrasive 4. In addition, these concave grooves 3 cool a grinding surface as striking a wind to an outer plate surface during operation at high speed. That is to say, these concave groove 3 of the disc paper 1 rotating at high speed produced a wind like a fan, an with this air cooling action, frictional heat in the outer plate is prevented from occurring, thus entanglement and loading of the paint film against the abrasive surface 5 to be produced by heat are checked.

Title: Vacuum cleaning method of molten metal
Inventor: ISHII TOSHIO
IPC: B22D1/00
Filed: 1988-10-07
Abstract: PURPOSE:To improve the capacity of the cleaning treatment of a molten metal by applying an electromagnetic force to the molten metal during bubbling and stirring and heating the molten metal. CONSTITUTION:The molten steel 2 is put into a vessel 1 and after the atmosphere therein is substd. with gaseous Ar, the molten steel is bubbled by blowing a prescribed gaseous mixture composed of gaseous Ar and gaseous H2 into the vessel 1 from the bottom thereof under the atmosphere pressure. The electromagnetic stirring of the molten steel 2 is executed by simultaneously applying the electromagnetic force to the molten steel by an electromagnetic coil 3 installed around the vessel 1 at this time. The gas bubbling and electromagnetic stirring are thereafter stopped and the pressure in the vessel 1 is rapidly reduced by a control valve, then the molten steel is rested in this state. As a result, the collision of the inclusions against each other is increased by the electromagnetic stirring and the inclusions relatively increased in the size float during the bubbling. The intrusion of these inclusions again into the molten metal due to the reduced pressure 2 is prevented and, therefor, the efficiency of removing the inclusions is improved.
