20090280350STEEL SHEET HAVING HIGH PLANE INTEGRATION AND METHOD OF PRODUCTION OF SAME - Steel sheet having a high {222} plane integration comprising steel sheet having an Al content of less than 6.5 mass % characterized by one or both of (1) a {222} plane integration of one or both of an αFe phase and γFe phase with respect to the steel sheet surface being 60% to 99% and (2) a {200} plane integration of one or both of an αFe phase and γFe phase with respect to the steel sheet surface being 0.01% to 15%.11-12-2009
20100291844DRESSER FOR ABRASIVE CLOTH - The invention provides a dresser for an abrasive cloth, which has a smaller abrasive grain diameter than the conventional dresser and has an abrasive grain spacing regulated in a predetermined range depending upon the abrasive grain diameter to simultaneously meet a high level of pad grinding power and a pad flatness and, at the same time, is less likely to cause dropout of abrasive grains. The dresser comprises a plurality of abrasive grains fixed as a single layer on a surface of a metallic support material. The dresser is characterized in that the metallic support material on its surface on which the abrasive grains are fixed has a convex shape, the difference in height between the end part and the central port on the surface is not less than 3 μm and not more than 40 μm, and the center-to-center spacing between at least one set of adjacent grains is d≦L<2d wherein d represents the diameter of the abrasive grains; L represents the center-to-center spacing between adjacent abrasive grains. The diameter (d) of the abrasive grains is preferably 3 μm≦d<100 μm.11-18-2010
