    Abstract: PROBLEM TO BE SOLVED: To provide coating equipment for boundary diffusion treatment which can uniformly coat Rpowder on a predetermined surface of a sintered body without excess or deficiency with predetermined thickness, by a predetermined pattern when grain boundary diffusion treatment is performed in manufacture of an NdFeB group sintered magnet, and by which automation and coating treatment to many sintered bodies are easy.SOLUTION: The coating equipment for grain boundary diffusion treatment comprises: a work loader 10; and a print head 20 provided on an upside rather than the work loader 10. The work loader 10 has: a base 11 which is movable in the horizontal direction; a lift 12 which is movable in the vertical direction to the base 11; a bar 13 which is attachably/detachably loaded on the lift 12; a tray 14 which is attachably/detachably loaded on the bar 13; a supporter 15 which is provided on the top surface of the tray 14; and a magnet clamp 16 whose vertical motion is possible. The print head 20 has: a screen 21 provided with a transmission part 211; and a squeegee 22 and a return scraper 23 which are movable while contacting the top surface of the screen 21.

    Abstract: The present invention relates to a method and an apparatus for producing a powder compact in which a recess (3) formed by die (d) and a lower punch (p1) inserted into said die is loaded with rubber mold (m) provided with a cavity (m') shaped according to the desired configuration of the compact, and subsequently, a powder is packed in the cavity of the rubber mold, and an upper punch (p2) is placed on die (d) to press the rubber mold with powder in the space formed by the die, the lower punch and the upper punch, thereby producing a powder compact. Because of the construction in which the upper punch is not inserted into the die but contacted at its bottom with the top of the die thereby carrying out the die pressing, the positioning of the indexed table does not have to be so accurate as in the prior art. The time for positioning is therefore shortened and the productivity is enhanced.

    Abstract: An adhesive layer forming method capable of forming an adhesive layer to a specified thickness in a step for forming the adhesive layer on the surface of a member to be treated for forming a film containing powder in the member to be treated. An adhesive layer forming medium (m1) coated with an adhesive substance is collided with the member to be treated (W) to move the adhesive substance from the adhesive layer forming medium (ml) to the member to be treated (W) to form the adhesive layer on the member to be treated (W). The adhesive layer formed on the member to be treated can be formed to the specified thickness by adjusting the thickness of the adhesive substance (amount of the adhesive substance held by each of the adhesive layer forming medium) applied onto the adhesive layer forming medium. Thus, a finally form ed powder film can also be formed in a specified thickness.
