| 20090087647 | Impact Absorption Sheet for Flat Panel Display, Process for Producing the Same, and Flat Panel Display - The present invention provides an impact absorption sheet for flat panel display with a polyoxyalkylene-series polymer as the main component, preferably, an impact absorption sheet for flat panel display made of a cured product obtained by curing a composition containing (A) polyoxyalkylene-series polymer having at least one alkenyl group in each molecule, (B) compound having an average of 2 or more hydrosilyl groups in each molecule, and (C) hydrosilylation catalyst. | 04-02-2009 |
| 20100317784 | INORGANIC POWDER-CONTAINING RESIN COMPOSITION, AND A SUBSTRATE HAVING A DIELECTRIC LAYER FORMED THEREON - An object is to provide an inorganic powder-containing resin composition excellent in an ability to disperse the inorganic powder and excellent in transferability upon formation into a sheet. Another object is to provide an inorganic powder-containing resin composition capable of forming a dielectric layer having highlight transmittance (without bubble defect) and excellent in surface smoothness. The present invention relates to an inorganic powder-containing resin composition comprising A) an inorganic powder, B) a binder resin, C) diglycerin, and D) at least one diglycerin fatty acid ester selected from the group consisting of a diglycerin fatty acid monoester, a diglycerin fatty acid diester, a diglycerin fatty acid triester, and a diglycerin fatty acid tetraester. | 12-16-2010 |
| 20110012460 | PERMANENT MAGNET FOR MOTOR, AND METHOD FOR MANUFACTURING THE PERMANENT MAGNET FOR MOTOR - The present invention relates to a permanent magnet for a motor, to be buried in a permanent magnet motor, including: a plurality of sheet magnets for lamination, and an insulating layer arranged between the plurality of sheet magnets for lamination. Since the invention has the above-mentioned constitution, the permanent magnets are free from the problems of temperature elevation and coercive force depression, therefore making it possible to provide a high-power small-sized motor. Furthermore, it is unnecessary to perform the conventional correcting processing after sintering, which can simplify the production steps, and therefore, it becomes possible to mold the permanent magnet with a high degree of dimension accuracy. | 01-20-2011 |
| 20110012700 | PERMANENT MAGNET AND METHOD FOR MANUFACTURING THE SAME - The present invention relates to a permanent magnet obtained by sintering a green sheet which is produced by mixing a magnet raw material with a resin binder and molding the resulting mixture, and a method for producing the same. Since the present invention has such a constitution, the contraction due to sintering becomes uniform, whereby the deformations such as warpage and depressions do not occur after sintering. Further, it is unnecessary to perform the conventional correcting processing after sintering, which can simplify the production steps, because the pressure unevenness at the time of pressing disappears. Therefore, it becomes possible to mold the permanent magnet with a high degree of dimension accuracy. Furthermore, even when the permanent magnet is reduced in film thickness, the magnetic characteristics are not deteriorated by the processing-deteriorated layer on the surface. | 01-20-2011 |
| 20110018664 | PERMANENT MAGNET AND METHOD FOR MANUFACTURING THE SAME - The present invention relates to a permanent magnet obtained by wet-mixing a Dy compound or a Tb compound with a magnet raw material to coat a surface of the magnet raw material with the Dy compound or the Tb compound, and sintering a green sheet obtained by mixing the resulting magnet raw material with a resin binder and molding the resulting mixture. Since the present invention has the above-mentioned constitution, it becomes possible to sufficiently improve coercive force by Dy or Tb while decreasing the amount of Dy or Tb used. Further, it can be prevented that Dy or Tb is solid-solutionized in magnet particles to decrease residual magnetization. | 01-27-2011 |
| 20110037548 | PERMANENT MAGNET AND PROCESS FOR PRODUCING PERMANENT MAGNET - The present invention relates to a permanent magnet manufactured by steps of: wet-pulverizing a high-melting metal element-containing organic compound or a precursor of a high-melting ceramic in a solvent together with a magnet raw material to pulverize the magnet raw material into fine particles having a grain size of 3 μm or less and to coat a surface of the pulverized magnet raw material with the high-melting metal element-containing organic compound or the precursor of the high-melting ceramic; adding a resin binder to the magnet raw material coated with the high-melting metal element-containing organic compound or the precursor of the high-melting ceramic; producing a slurry by kneading the magnet raw material and the resin binder; molding the slurry into a sheet form to prepare a green sheet; and sintering the green sheet. | 02-17-2011 |
| 20110043311 | PERMANENT MAGNET AND PROCESS FOR PRODUCING PERMANENT MAGNET - The present invention relates to a permanent magnet manufactured by steps of: pulverizing a magnet raw material; mixing the pulverized magnet raw material with a rust preventive oil in which a Dy compound or a Tb compound is dissolved, thereby preparing a slurry; compression molding the slurry to form a molded body; and sintering the molded body. | 02-24-2011 |
