摘要： A stator 13 on whose outer circumference a plurality of magnetic poles 13a are arranged is mounted on a substrate 11, and a rotor 14 is rotatably disposed around the stator. The inner circumferential face of the rotor is provided with a magnet 15 magnetized to have alternately opposite polarities in a direction opposing the stator, and magnetized to have alternately opposite polarities in a direction opposing the substrate. The outer circumferential ends of the magnetic poles of the stator are provided with a first extended portion 13c that extends from a magnetic pole base 13d to the substrate side, and a second extended portion 13b that extends from the magnetic pole base to a side opposite the substrate side. A face of the substrate opposing the rotor is provided with a FG pattern 19 outside the outer circumferential face of the stator such that the FG pattern opposes the magnet. Accordingly, it is possible to improve the precision in detecting the rotational speed by reducing noise superimposed on the FG signal, while securing a high driving efficiency.

摘要： A method of manufacturing anisotropic bonded magnets includes four steps. The first step fills a compressing metal mold with a compound chiefly made of flaky anisotropic magnetic particles. The second step forms a compression molded substance by molding the compound in the metal mold within an orientation magnetic field. The third step couples the compressing metal mold to a molding metal mold together. The fourth step moves the compression molded substance from the compressing metal mold to the molding metal mold, and then deforms and molds the compression molded substance into a given shape. This method allows controlling the anisotropy of the anisotropic bonded magnet.

摘要： An ink ejecting device includes ink channels intercommunicating with slits and air channels intercommunicating with another slits. The ink channels and the air channels have a narrow shape with a rectangular cross-section, and all of the ink channels are filled with ink and the air channels are filled with air. An LSI chip applies a voltage V to a pattern conducting to metal electrodes positioned in air channels located at both sides of an ink channel from which the ink is to be ejected and connects the other patterns connected to metal electrodes in other air channels not adjacent the ejecting ink channel and a pattern conducting to the metal electrodes of the non-ejecting ink channels to a ground line. Therefore, the ink ejecting device of the above structure requires no insulation between ink and electrodes as the working electrodes do not contact the ink.
