摘要： A method for manufacturing a rare-earth magnet, through hot deformation processing, having a high degree of orientation at the entire area thereof and high remanence, without increasing processing cost including a step of press-forming powder as a rare-earth magnetic material to form a compact S; and a step of performing hot deformation processing to the compact S, thus manufacturing the rare-earth magnet C. The hot deformation processing includes two steps of extruding and upsetting. The extruding is to place a compact S in a die Da, and apply pressure to the compact S′ in a heated state with an extrusion punch PD so as to reduce the thickness for extrusion to prepare the rare-earth magnet intermediary body S″ having a sheet form, and the upsetting is to apply pressure to the rare-earth magnet intermediary body S″ in the thickness direction to reduce the thickness, thus manufacturing the rare-earth magnet C.

摘要： A method for producing a raw material powder of a permanent magnet, includes: preparing a material powder of a permanent magnet, measuring magnetic characteristics of the material powder, and judging the quality of the material powder as the raw material powder based on a preliminarily determined relation between magnetic characteristics and the structure of the material powder. A method for producing a permanent magnet includes integrating material powders judged as good in the step of judging the quality as raw material powders by the method for producing a raw material powder of a permanent magnet. A method for inspecting a permanent magnet material powder includes transmitting a magnetic field to a material powder of a permanent magnet, receiving the magnetic field from the material powder, and measuring a magnetic field difference between the transmitted magnetic field and the received magnetic field as magnetic characteristics of the material powder.

摘要： The guide vanes comprise two kinds of guide vanes which are alternately placed in the circumferential direction of a shroud. One kind of the guide vanes have a longer length than the other kind of the guide vanes, in the region which is close to the surface of the hub, but have substantially the same length as the other kind of the guide vanes, in the region which is close to the shroud. The leading edges of the second kind of guide vane are located further downstream in the pump axial direction than the leading edges of the first kind of guide vanes.

摘要： A hexagonal ferrite magnetic powder having an average tabular diameter of from 15 to 30 nm, a coercive force (Hc) of from 2,000 to 5,000 Oe (from 160 to 400 kA/m) and a saturated magnetization (σs) of equal to or more than the average tabular diameter (nm)×0.37+45 A·m2/kg. This magnetic powder is obtained by melting a starting material containing a material which has a composition within the hatched region (1) in the triangular phase diagram shown in FIG. 1 and quenching the molten product to obtain an amorphous product, subjecting the amorphous product to a thermal treatment, acid treatment, and washing. Also, a magnetic recording medium is obtained by adding this magnetic powder to the magnetic layer and coating it on the support.
