Publication number: 20130328433Abstract: A method of manufacturing a bonded-magnet rotor according to the invention includes forming step and arranging step. The forming step is by forming a bonded-magnet formed body. The arranging step includes: integrating an inside-diameter holding jig, a rotor core, and a rotor-core presser jig; arranging the bonded-magnet formed bodies on the outside periphery of the inside-diameter holding jig; and arranging an outside-diameter-holding magnet-pressure-welding jig to support outside peripheral faces of the bonded-magnet formed bodies. The method further includes steps of: deforming the bonded-magnet formed bodies to fit with the outside peripheral dimension of the rotor core by pressing and transferring the bonded-magnet formed bodies to the rotor core with a forming jig; mutually joining end portions of adjacent ones of the bonded-magnet formed bodies; and integrating the bonded-magnet formed bodies with the rotor core by compressing the bonded-magnet formed bodies.Type: ApplicationFiled: March 23, 2012Publication date: December 12, 2013Applicant: PANASONIC CORPORATIONInventor: Hiroki Asai

Publication number: 20130026863Abstract: 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.Type: ApplicationFiled: January 31, 2012Publication date: January 31, 2013Applicant: PANASONIC CORPORATIONInventor: Hiroki Asai

Patent number: 5764247Abstract: A drive method for an ink ejection device that cancels residual pressure fluctuations using a signal drive power source, wherein at time (b) a positive voltage V from a single power source is applied to an ink chamber 4b1 and other ink chambers 4 are connected to ground. Therefore, the volume of ink chamber 4b1 increases from a natural volume. At time (c), voltage V applied to the ink chamber 4b1 is stopped and a positive voltage V from the single power source is applied to the other ink chambers 4 so that the volume in the ink chamber 4b1 is reduced from the increased volume to an extent beyond the natural volume that causes an ink droplet to be ejected from the nozzle 12 of ink chamber 4b1. At timing (d), application of positive voltage V to the ink chambers 4c0, 4a1, 4c1, 4a2, 4b2, and 4c2 is stopped so that all the ink chambers revert to the natural volume.Type: GrantFiled: November 9, 1994Date of Patent: June 9, 1998Assignee: Brother Kogyo Kabushiki KaishaInventor: Hiroki Asai

Patent number: 5646661Abstract: 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.Type: GrantFiled: October 18, 1994Date of Patent: July 8, 1997Assignee: Brother Kogyo Kabushiki KaishaInventors: Hiroki Asai, Qiming Zhang, Hiroto Sugahara
