Patent number: 11209203Abstract: To provide an ice making device including an ice making tray, a drive unit configured to turn over the ice making tray, a frame including a frame body, the frame configured to support the ice making tray, and a fan motor configured to send wind to the ice making tray. The frame includes a block unit configured to contact a part of the ice making tray turning over to partially disturb the turning over of the ice making tray, and the fan motor is fixed only to a first frame part including one of a plurality of frame parts constituting sides surrounding a periphery of the ice making tray in a plan view of the frame.Type: GrantFiled: March 4, 2020Date of Patent: December 28, 2021Assignee: NIDEC SANKYO CORPORATIONInventors: Shunji Saito, Akihiro Ito, Takaji Harata

Patent number: 11181310Abstract: In an ice maker, water from a water supply pipe passes through a water flow port provided in a frame and is poured into a water receiving unit protruding outward from an ice making tray 5. The frame includes a first water channel portion intersecting a direction of an axis and the water flow port is provided in a side surface of the first water channel portion on a side of the ice making tray. Further, the frame includes a convex unit functioning as a water blocking unit and provided in a position on the upstream side of the water flow port and along the side surface in which the water flow port is provided. As a result, it is possible to prevent or suppress water flowing in a direction different from the opening direction of the water flow port, from reaching the water flow port.Type: GrantFiled: September 20, 2019Date of Patent: November 23, 2021Assignee: NIDEC SANKYO CORPORATIONInventors: Takaji Harata, Katsuhiko Hayashi

Patent number: 7994663Abstract: A motor may include a motor base plate, a bearing holder provided with a through hole whose both ends hold bearings and vertically disposed with respect to the motor base plate, a stator provided with a center hole and fixed to an outer peripheral face of the bearing holder, and a rotor having a shaft supported by the bearings, a rotor case fixed to the shaft, and a magnet fixed on an inner peripheral face of the rotor case. The bearing holder may be provided with a stepped part, protruded toward a radial direction. The stator may be provided with a first resin block structured so that an end face on a motor base plate side of the stator core is molded with resin to cover a coil wound around the stator core, and inner peripheral faces of the stator core and the first resin block structure the center hole, and the center hole of the stator is press-fitted and fixed to the bearing holder until an end face of the first resin block is abutted with the stepped part.Type: GrantFiled: November 30, 2009Date of Patent: August 9, 2011Assignee: Nidec Sankyo CorporationInventors: Takaji Harata, Makoto Fujishima

Publication number: 20050132840Abstract: An automatic balancing device including a case body provided with a hollow annular member having an outer peripheral side sliding wall face and concentrically mounted on a rotation shaft, a plurality of balance spherical bodies which are accommodated within the inside of the hollow annular member of the case body and disposed movably in a free manner when the rotation body is rotated, and a lubricant containing a liquid system lubricant which is adhered in a film manner on at least the outer peripheral side sliding wall face of the case body. The lubricant containing a liquid system lubricant may be preferably coated in a concentrated manner on the sliding face, then rotationally driving the rotation body and then suddenly stopping the rotation body to adhere the lubricant in a film manner on the outer peripheral side sliding wall face of the case body.Type: ApplicationFiled: November 3, 2004Publication date: June 23, 2005Inventors: Atsushi Honda, Masaru Uno, Takaji Harata

Publication number: 20040261568Abstract: An automatic balancing system is provided for canceling a rotational imbalance of a rotary device that includes a body to be rotated. A rotation support member rotates with the rotary device and has a polyhedron shape to have multiple flat ball operating surfaces that define an outer circumferential surface. A hollow storage channel around the rotation support member provides an inner circumferential surface so that the balance balls positioned in the hollow storage channel can move freely between the outer circumferential surface and the inner circumferential surface. The polyhedron shape of the ball operating surfaces allows the balance balls to come in contact with the surfaces with minimized force during low speed rotation and beginning of rotation to prevent abrupt collisions of the balance balls which results in smooth and quiet operation of the rotary device.Type: ApplicationFiled: April 30, 2004Publication date: December 30, 2004Inventors: Shinichi Utsumi, Atsushi Honda, Takaji Harata, Masaru Uno
