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 |
