Patent number: 6379858Abstract: A honing means produces sonic waves that suspend and propel a honing medium against a surface of a substrate. The honing medium impinges on the surface of the substrate and alters the substrate's surface roughness. The substrate and the honing means are positioned relative to each other to ensure substantial surface roughness uniformity.Type: GrantFiled: August 14, 2000Date of Patent: April 30, 2002Assignee: Xerox CorporationInventors: Philip G. Perry, Gene W. O'Dell, William G. Herbert, Alexander A. Antonelli

Patent number: 6336844Abstract: The invention relates to a method and machine for so-called “ultrasonic” peening employing a mist of microbeads inside an active chamber 30c for peening parts 21 on a wheel 19, ie blades on a rotator. The periphery of the wheel 19 is brought simultaneously past the openings of at least three chambers with limited clearances E1 and E2. At least one chamber being active with a peening mist of microbeads and at least two chambers, either side of the active chamber, being passive. The wheel being rotated over the chambers and the microbeads are removed from the passive chambers and in that the active chambers are supplied with microbeads therefrom.Type: GrantFiled: November 17, 2000Date of Patent: January 8, 2002Assignee: Snecma MoteursInventors: Catherine Dominique Béatrice Duquenne, Véronique Christiane Raymonde Giffard, Gérard Michel Roland Gueldry, Claude Marcel Mons

Patent number: 6315644Abstract: An apparatus of this invention for supplying an abrasive for use in the manufacture of semiconductors comprises a storage tank of the abrasive and a supply line for guiding the abrasive from the storage tank to a nozzle for supplying the abrasive to an object to be polished and said storage tank or supply line is provided with a device for furnishing ultrasonic wave to sonicate the abrasive. A process of this invention for supplying an abrasive for use in the manufacture of semiconductors comprises sonicating the abrasive by ultrasonic wave before supplying it to an object to be polished. The apparatus and process of this invention for supplying an abrasive for use in the manufacture of semiconductors make it possible to supply an abrasive containing a minimized amount of abnormally agglomerated particles to the surface of an object to be polished in the manufacturing step of semiconductors and improve the yield of polished products.Type: GrantFiled: November 22, 1999Date of Patent: November 13, 2001Assignee: Tama Chemicals Co., Ltd.Inventors: Toshitsura Cho, Akira Iwashiro
