Publication number: 20150213833Abstract: In a rotating device, a recording disk is mounted on a hub. A base rotatably supports the hub via a bearing unit. A core is fixed to the base with a ring portion and a plurality of teeth, with coils wound there around. The bearing unit includes a cylindrical portion that surrounds a radial dynamic pressure groove. The base includes an integrated surrounding portion protruding toward the hub, with the ring portion glued there around. The base further includes an integrated increasing-thickness portion arranged outside of the surrounding portion such that the increasing-thickness portion becomes thicker the closer it is to the surrounding portion. The cylindrical portion is surrounded by the surrounding portion, the surrounding portion is surrounded by the increasing-thickness portion, and a surface of the increasing-thickness portion at least partly overlaps the radial dynamic pressure groove in the axial direction.Type: ApplicationFiled: April 9, 2015Publication date: July 30, 2015Applicant: Samsung Electro-Mechanics Japan Advanced Technology Co., Ltd.Inventors: Takanori WATANABE, Takuji YAMADA, Susumu ANDO, Hiroshi IWAI

Patent number: 9030775Abstract: In a disk drive device, a magnetic recording disk is mounted on a hub. A base rotatably supports the hub via a bearing unit. The base has a ring-shaped wall that surrounds the bearing unit and that protrudes towards the hub. A laminated core is fixed to the base. The laminated core has a ring portion and twelve teeth that radially outwardly extend from the ring portion. Coils are wound around the twelve teeth. The base includes an increasing-thickness portion formed so that the less the distance between a part of the increasing-thickness portion and the ring-shaped wall is, the thicker the part of the increasing-thickness portion becomes.Type: GrantFiled: May 10, 2011Date of Patent: May 12, 2015Assignee: Samsung Electro-Mechanics Japan Advanced Technology Co., Ltd.Inventors: Takanori Watanabe, Takuji Yamada, Susumu Ando, Hiroshi Iwai

Patent number: 8724295Abstract: A positive electrode 21 and negative electrode 22 formed of a thin metal plate are disposed on the same plane with a space provided therebetween. An insulative resin is disposed in the space between the both electrodes. The insulative resin electrically insulates the positive and the negative electrodes, and making both electrodes integrated as a sheet to form a terminal board. Positive- and negative-electrode drawing portions are formed on the same surface of the main body of a capacitor element, and that surface serves as a joined face with the terminal board. With the terminal board being superimposed on the joined face of the capacitor element, the metal plate forming the positive and negative electrodes of the terminal board are electrically coupled to the positive- and negative-electrode drawing portions of the element, respectively.Type: GrantFiled: August 21, 2009Date of Patent: May 13, 2014Assignee: Nippon Chemi-Con CorporationInventors: Susumu Ando, Shigeki Shirase

Patent number: 7200917Abstract: A number of embodiments of rotating electrical machines and methods for winding them that provides a high space utilization and very effective winding with less likelihood of damage to the insulation of the wire of the winding during the winding process. The arrangement basically does not require the winding needle to be moved back and forth in the slot between the poles but rather employs insulating inserts that are positioned on the axial faces of the poles outside of the gaps for guiding the wire from one end to the other so as to provide the high space utilization. In one embodiment the insulating insert effectively changes the circumferential length of the coil winding that decreases in an axial direction along their length.Type: GrantFiled: September 28, 2004Date of Patent: April 10, 2007Assignee: Kabushiki Kaisha MoricInventors: Tadashi Takano, Susumu Ando

Patent number: 7102263Abstract: A number of embodiments of rotating electrical machines using permanent magnets wherein the cogging torque is substantially reduced as are vibrations caused by magnetic flux variations. This is accomplished by disposing the coil windings in equal circumferential spacing and disposing the associated permanent magnets in non-symmetrical relationship so that the gaps between some of the magnets are different. In addition, the coil windings are such that no two coils of any phase are immediately adjacent each other in a circumferential direction. A method for calculating the optimum spacing is also disclosed.Type: GrantFiled: December 10, 2001Date of Patent: September 5, 2006Assignee: Kabushiki Kaisha MoricInventors: Tadashi Takano, Hideaki Takahashi, Susumu Ando

Patent number: 6836044Abstract: Two embodiments of rotating electrical machines wherein the cogging torque is substantially reduced by increasing the cogging number without increasing the number of pole teeth and permanent magnets. This is done by selecting the appropriate magnet angle to increase the number of coggings per revolution and this can be done using a computer analysis of the cogging torque for the individual magnets rather than by a trial and error method.Type: GrantFiled: October 22, 2002Date of Patent: December 28, 2004Assignee: Kabushiki Kaisha MoricInventors: Susumu Ando, Hideaki Takahashi

Patent number: 6745972Abstract: Two embodiments of winding methods and apparatus for winding coils of a rotating electrical machine where the armature teeth are skewed. The winding mechanism and method operates so that the winding needle does not have to enter to the bottom of the slots between the pole teeth but the wire is wound around the pole teeth from one end thereof with an arrangement for causing the windings to progressively move down the pole teeth as the winding continues.Type: GrantFiled: July 25, 2002Date of Patent: June 8, 2004Assignee: Kabushiki Kaisha MoricInventors: Tadashi Takano, Susumu Ando, Yoshio Kato

Patent number: 6685126Abstract: Armature structures and methods that provide very dense coil windings and afford very rapid winding methods at a relatively low cost. In addition the likelihood of damaging the already wound wires by contact with the winding nozzle is substantially eliminated. This is achieved by moving the winding needle in varying distances and directions away from the pole teeth to induce varying degrees of slack in the wire during the winding and when the needle is not in the slot between the pole teeth.Type: GrantFiled: July 25, 2002Date of Patent: February 3, 2004Assignee: Kabushiki Kaisha MoricInventors: Tadashi Takano, Susumu Ando, Yoshio Kato
