摘要： In the rare earth sintered magnet, the ratio of R2 to the sum of R1 and R2 that are contained in crystal grain boundaries surrounding the crystal grains in the rare earth sintered magnet body is higher than the ratio of R2 to the sum of R1 and R2 in the crystal grains, and the concentration of R2 increases from the central portion of the rare earth sintered magnet body toward the surface of the rare earth sintered magnet body. In addition, the degree of unevenness in residual magnetic flux density on the surface of the rare earth sintered magnet body is smaller than 3.0%.

摘要： The method is related to intermittent coating capable of distinctly defining a boundary between a coated region and an uncoated region on a web, to thereby intermittently form a coated film on the web with increased accuracy and efficiency. A coating liquid feed pump is arranged so as to alternately communicate with a circulation line and a pocket of an extrusion type coater through a directional control valve, resulting in coating liquid being intermittently fed to the pocket and then forced out of a slit, so that coated regions and uncoated regions may be alternately formed on a conductive sheet material. During interruption of communication between the pocket and the feed pump, the pocket is permitted to communicate via a discharge pipe and a shut-off valve with a sub-tank to reduce a pressure of coating liquid in the pocket, to thereby prevent undesired feeding of coating liquid to the uncoated region beyond an end position of the coated region.
