摘要： To improve the performance of a rare-earth magnet, it is effective to use a low-oxidized powder having a small grain size. One objective of the present invention is to provide a method for manufacturing a sintered rare-earth magnet having a magnetic anisotropy, in which a very active powder having a small grain size can be safely used in a low-oxidized state. Another objective is to provide a method capable of efficiently manufacturing products having various shapes. In a weighing and loading section 41 and a high-density loading section 42, a fine powder as a material of the sintered rare-earth magnet having a magnetic anisotropy is loaded into a mold until its density reaches a predetermined level. Then, in a magnetic orientation section 43, the fine powder is oriented by a pulsed magnetic field. Subsequently, the fine powder is not compressed but immediately sintered in a sintering furnace 44. The present method enables the mass-producing machine to be simple in its operation and its housing to be accordingly smaller, so that it will be possible to eliminate the danger of oxidization or burning of the powder, which has been a serious problem for a conventional method that uses a large-scale die-pressing machine. Furthermore, the manufacturing efficiency can be improved by using a multi-cavity mold for manufacturing a sintered rare-earth magnet having an industrially important shape, such as a plate magnet or an arched plate magnet.

摘要： The present invention relates to a packing method and an apparatus implementing said method in which a material is packed into a container by an air tapping process in which the air-pressure state of the space comprising a container and a space part connected with said container, which space being loaded with the material, is switched several times from a low air-pressure state to a high air-pressure state alternately, while keeping said low at-pressure state equal to or higher than the atmospheric pressure existing outside said space, thereby preventing the material from getting blown up by the inflow of the atmospheric air outside the container and packing a material into said container homogeneously.

摘要： A powder compaction method in which a powder p is filled by air tapping or other suitable method into a mold 1, then while the mold 1 being filled with the powder, the powder particles are bound with each other without application of force from outside the mold to form a compact C, and then the compact C is taken out from the mold 1. This method produces a variety of shapes of the compact far greater than in conventional methods, and net shape manufacturing of products with complex shapes is made possible by this method. Because this method uses far less binder compared to MIM and PIM that are expected as methods for producing products with complicated shapes, the time needed for elimination of the binder is much shorter than in MIM and PIM.
摘要翻译：粉末压制方法，其中粉末p通过空气攻丝或其它合适的方法填充到模具1中，然后当模具1填充粉末时，粉末颗粒彼此结合，而不受模具外部的作用力以形成紧凑的C，然后将紧凑的C从模具1中取出。该方法产生比常规方法更大的多种形状的紧凑形状，并且通过这种方法可以实现具有复杂形状的产品的净形状制造方法。由于与MIM和PIM相比，该方法使用的粘合剂比预期的复杂形状的产品的方法要少得多，因此消除粘合剂所需的时间比MIM和PIM短得多。
