    摘要： A secondary cooling apparatus capable of gradually cooling cast thin pieces and a cast apparatus that uses it are provided. A comb tooth-shaped device is arranged inside a vessel of the secondary cooling apparatus; the cast thin pieces are piled on the comb tooth-shaped device; and crushed small pieces are placed thereon. After the cast thin pieces and the crushed small pieces are gradually cooled, the cast thin pieces are crushed by a pressing device. The crushed small pieces are rapidly cooled by being in contact with a surface of a bottom wall and side faces of cooling teeth. Nd-rich phases or R-rich phases can be annealed by the gradual cooling, and after the crushed small pieces are rapidly cooled to its oxidation temperature or below, the crushed small pieces can be taken out to the air atmosphere.

    摘要： A harmonic suppression resonator comprises a plurality of waveguide resonators that resonate in TE mode, in which harmonic suppression resonator, adjoining resonators are coupled via a plurality of coupling windows. Four coupling windows 33bc1, 33bc2, 33bc3 and 33bc4 are provided between a resonant region 51b and a resonant region adjoining the resonant region 51b. These coupling windows allow fundamental wave modes of the adjoining resonators to be coupled mainly by magnetically coupling. The coupling windows 33bc3 and 33bc4 allow second harmonic modes of the adjoining resonators to be electrically coupled, and the coupling windows 33bc1 and 33bc2 allow the second harmonic modes of the adjoining resonators to be magnetically coupled. By causing the amount of the electrically coupling and the amount of the magnetically coupling to be substantially equal, the coupling of the second harmonic modes is negated, whereby propagation of the second harmonic is blocked.

    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.
