20110005143POLISHING OIL SLURRY FOR POLISHING HARD CRYSTAL SUBSTRATE - A hard crystal substrate such as a GaN substrate or a SiC substrate is polished by using polishing oil slurry having abrading particles of artificial diamond clusters dispersed in a dispersant. The artificial diamond clusters include approximately spherical agglomerate particles with average particle size D50 of 20 nm or more and 50 nm or less, having primary particles with particle diameters of 2 nm or more and 10 nm or less. A rough polishing process is carried out first such that an average surface roughness of 0.5 nm or more and 1 nm or less is obtained, followed by a finishing process such that the average surface roughness of said surface becomes 0.2 nm or less.01-13-2011
20100170161METHOD FOR TREATING SPENT ABRASIVE SLURRY - The present invention relates to a method and a system for treating spent abrasive slurry obtained from a process for cutting a body of a substrate material into wafer-like slices, said slurry comprising a lubricant fluid, unspent abrasive particles and fines.07-08-2010
20090094901CMP Polishing Liquid and Polishing Method - A CMP polishing liquid being capable of using in a chemical mechanical polishing comprising of: a first chemical mechanical polishing step of polishing a conductive substance layer of a substrate having an interlayer insulation film containing convex and concave regions on a surface thereof, a barrier layer coating along the surface of the interlayer insulation film, and the conductive substance layer coating the barrier layer while filling the concave regions, and thus exposing the barrier layer in the convex regions; and a second chemical mechanical polishing step of exposing the interlayer insulation film in the convex regions by polishing the barrier layer exposed in the first chemical mechanical polishing step; characterized in that a difference (B)−(A) is 650 {acute over (Å)} or less, 04-16-2009
20100064593SLURRIES CONTAINING ABRASIVE GRAINS HAVING A UNIQUE MORPHOLOGY - A slurry containing a plurality of monocrystalline diamond particles, wherein the average surface roughness of said particles is less than about 0.95; a major vehicle selected from the group of water-based vehicles, glycol-based vehicles, oil-based vehicles or hydrocarbon-based vehicles and combinations thereof; and one or more optional additives.03-18-2010
20120240477COMPOSITIONS COMPRISING 2,3,3,3-TETRAFLUOROPROPENE, 1,1,2,3-TETRA-CHLOROPROPENE, 2-CHLORO-3,3,3-TRIFLUOROPROPENE, OR 2-CHLORO-1,1,1,2-TETRAFLUOROPROPANE - The present disclosure relates to compositions comprising 2,3,3,3-tetrafluoropropene that may be useful as heat transfer compositions, aerosol propellants, foaming agents, blowing agents, solvents, cleaning agents, carrier fluids, displacement drying agents, buffing abrasion agents, polymerization media, expansion agents for polyolefins and polyurethane, gaseous dielectrics, extinguishing agents, and fire suppression agents in liquid or gaseous form. Additionally, the present disclosure relates to compositions comprising 1,1,2,3-tetrachloropropene, 2-chloro-3,3,3-trifluoropropene, or 2-chloro-1,1,1,2-tetrafluoropropane, which may be useful in processes to produce 2,3,3,3-tetrafluoropropene.09-27-2012
20090139148SUPERABRASIVE GRAIN SETTING METHOD - In a superabrasive grain setting method, a two-dimensionally developed coordinate preparation step is taken, wherein a non-cylindrical area of a mounting surface where a tangential line to the mounting surface in a plane including the axis of the manufacturing mold crosses with the axis of a manufacturing mold is developed into a circular-arc belt-like surface, and a plurality of mounting points are set on the circular-arc belt-like surface in a grid pattern in dependence on mounting positions for superabrasive grains. Then, a rectification step is taken, wherein the grid pattern of the mounting points is rectified in predetermined angular ranges so that the mounting points do not make consecutive point lines in the circumferential direction of the circular-arc belt-like surface. A mounting step is thereafter taken of mounting the superabrasive grains on the mounting surface of the manufacturing mold based on the grid pattern rectified at the rectification step.06-04-2009
20100251623METHOD OF ASSEMBLING INNER DIAMETER GRINDING TOOL - A tool for grinding an inner diameter even when holders having grindstones are axially connected. A gap enclosed by the inner peripheral surface of a divided tool holder, a draw bar and O-rings is formed in a state in which the draw bar is inserted into a tool holder in which a plurality of divided tool holders are connected in series. A filler is filled into the gap to fix a support bush to the divided tool holder. An adjustment screw of each arm held circumferentially away from each other on the divided tool holder is turned to adjust a distance between a pin and the arm, and the radial projecting amount of each of grindstones is adjusted. The projecting amount is adjusted such that the plurality of grindstones rotate along the same rotational trajectory and the center of the rotational trajectory corresponds to the axis of the draw bar.10-07-2010
20120192500COATED ABRASIVE AGGREGATES AND PRODUCTS CONTAING SAME - A coated abrasive product includes a particulate material containing green, unfired abrasive aggregates having a generally spheroidal or toroidal shape, the aggregates formed from a composition comprising abrasive grit particles, a nanoparticle binder, a dual function material, and a cross-linking agent. These green unfired abrasive aggregates can also be used in free abrasive products and bonded abrasive products.08-02-2012
20110056143INTERMEDIATE PRODUCT FOR USE IN THE PRODUCTION OF ABRADING OR CUTTING TOOLS - An intermediate product for use in the production of abrading or cutting tools has the form of a soft, easily deformable paste comprising powdery sinterable matrix material, binding agent and solvent for the binding agent, the paste having superabrasive particles dispersed therein, the superabrasive particles being individually encrusted within a coating of presintered material.03-10-2011
20130118091Methods For Processing Abrasive Slurry - Systems and methods are provided for processing abrasive slurry used in cutting operations. The slurry is mixed with a first solvent in a tank. The slurry is vibrated and/or ultrasonically agitated such that abrasive grain contained in the slurry separates from the other components of the slurry and the first solvent. After the abrasive grain has settled to a bottom portion of the container, the other components of the slurry and the first solvent are removed from the tank. The abrasive grain may then be washed with a second solvent. The abrasive grain is then heated and is suitable for reuse in an abrasive slurry.05-16-2013
20110232198BACKINGLESS ABRASIVE ARTICLE - An abrasive article includes an abrasive layer having an array of protrusions. The abrasive layer has a thickness not greater than about 500 mils. The abrasive article is free of a backing layer.09-29-2011
