An Nd-Fe-B sintered magnet may be used as the permanent magnet matrix, and dysprosium (Dy) may be used as the metal having higher coercivity performance. A plurality of straight recessed portions 12, 14 and 16 or straight grooves may be used as the notch portions.

摘要： There are provided a rare-earth permanent magnet and a manufacturing method of the rare-earth permanent magnet capable of preventing deterioration of magnet properties. In the method, magnet material is milled into magnet powder, and the magnet powder is mixed with a binder made of a hydrocarbon to prepare slurry 12, and one or more kinds of organic solvents selected from a group of organic compounds consisting of hydrocarbons. Next, the slurry 12 is formed into a sheet-like shape to obtain a green sheet 13. After that, the green sheet 13 is held for a predetermined length of time at binder decomposition temperature in a non-oxidizing atmosphere so as to cause depolymerization reaction or the like to the binder, which turns into monomer and is removed. The green sheet 13 with the binder removed is sintered by raising temperature up to sintering temperature. Thereby a permanent magnet 1 is obtained.

摘要：計測した誤差磁場分布を特異値分解により得た固有モード成分に分解し、各モードに対応した鉄片配置を組み合わせてシムトレイ(5)上に配置する。補正する固有モードは到達可能な磁場精度(均一度)と鉄片配置量の適切さで選択する。到達できる磁場精度(均一度)を把握しながら調整できるので、間違った調整も把握でき、また繰り返し調整する中で自動的に補正できる。本発明による方法でまたこの方法を内蔵した装置による支援で、磁場調整を行うと確実に磁場調整が繰り返し作業の中で完了していく。その結果磁場精度の良い装置を提供できる。また到達可能均一度(17)を調べることで、不良な磁石を早期に検知できる特徴もある。
