摘要： Pressing device (100) comprises an air-tight container (30) for storing a rare earth alloy powder; an air-tight feeder (20) which is able to move between a powder filling position and a retaining position; and an air-tight powder feeding device (40) formed in such a way that the powder can be added to the feeder without it coming into contact with atmospheric air. Preferred Features: A device for delivering an inert gas into the powder feeding device is provided so that the oxygen concentration in the powder feeding device and the feeder is controlled to 50000 vol.-ppm or more during pressing.

摘要： Powder pressing device comprises a mold (10) with a non-magnetic section and a magnetic section with a through-hole extending through the two sections; a magnetic core (12a) having an outer periphery lying over the inner wall of the hole of the mold; a lower stamp (14) which is introduced into a hollow chamber from below; an upper stamp (16) inserted into the hollow chamber from above; a powder charging device for filling the hollow chamber with a magnetic powder; a magnetic field generator; and controlling devices. An Independent claim is also included for a process for producing a molded part made of a rare earth metal alloy using the pressing mold. Preferred Features: The rare earth alloy powder consists of a R-T-(M)-B alloy (where, R = Y, La, CE, Pr, Nd, Sm, Gd, Tb, Dy, Ho, Er, Tm or Lu; T = Fe and/or Co; M = an additional element; and B = boron).

摘要： PROBLEM TO BE SOLVED: To provide a method of surely magnetizing parts near a boundary between the regions of magnets more surely in the prescribed directions than usual, when the magnets arranged into the shape of a cylinder are magnetized respectively so as to form the regions which are magnetized in opposite directions. SOLUTION: This magnetizing method comprises a preparation process of preparing a rare earth magnets 22 arranged so as to form a cylinder 22a; a first magnetizing process of forming a first region R1 which is magnetized so as to generate a magnetic flux extending from inside the cylinder 22a toward its outside, and a second region R2 which is magnetized so as to generate a magnetic flux extending from outside the cylinder 22a toward its inside; and a second magnetizing process of applying a second external magnetic field H2 so as to apply an external magnetic field component, whose direction makes an angle of above 0 deg. to below 50 deg. with that of the external magnetic field component which is applied in the first magnetizing process to the boundary between the first region R1 and the second region R2.
