Patent number: 10036182Abstract: An electronic locking system provided with an electronic lock may include a lock detecting part to detect locking condition of the lock; a power outage-detecting part to detect power outage; a charging part to supply electric power to the lock during power outage; a power-supplying part to supply power to the lock and charging part; and a switching part structured such that power is supplied to the lock from the power-supplying part in a primary state, and power is supplied to the electronic lock from said charging part in a secondary state. The switching part is in said primary state during normal operation where no power outage is detected. The switching part is structured such that, when power outage is detected, said switching part is switched from said primary state to said secondary state.Type: GrantFiled: January 27, 2016Date of Patent: July 31, 2018Assignee: NIDEC SANKYO CORPORATIONInventors: Shinichi Yoshikawa, Noboru Ashibe, Goro Nakamura

Patent number: 7118278Abstract: A suitable the inner point is set on a vapor-liquid face of lubricating fluid formed in a composite capillary seal section that utilizes capillary force and rotational centrifugal force acted on the lubricating fluid. An inner peripheral surface of a ring-shaped portion is formed such that the minimum value R1 in radial-direction distances of the inner peripheral face of the ring-shaped portion becomes greater than a radial-direction distance R2 of the inner point (R1>R2). This can observe the inner point of the lubricating fluid from the immediately-above position, whereby the filling amount of the lubricating fluid can easily and surely be measured, thereby being capable of adjusting the filling amount of the lubricating fluid to a preset amount.Type: GrantFiled: June 11, 2004Date of Patent: October 10, 2006Assignee: Nidec CorporationInventors: Masato Gomyo, Noboru Ashibe, Junya Mizukami

Patent number: 7059771Abstract: A motor with fluid dynamic pressure bearing is disclosed. The motor includes a dynamic pressure bearing member having a concave section that is concave in an axial direction, a rotary shaft that is rotatively supported by the dynamic pressure bearing, and a rotary member that is joined to the rotary shaft in one piece along a joint section between the rotary member and the rotary shaft, and rotatively driven by electromagnetic drive force, an expanded diameter section that is provided on the dynamic pressure bearing member. A fallout preventing member is provided on the rotary member, which overlaps the expanded diameter section of the dynamic pressure bearing member in the axial direction to prevent the rotary shaft from falling out of the dynamic pressure bearing member.Type: GrantFiled: May 15, 2003Date of Patent: June 13, 2006Assignee: Nidec Sankyo CorporationInventors: Masato Gomyo, Noboru Ashibe, Shingo Suginobu

Patent number: 6967421Abstract: A motor includes a core having a common connection section formed in a ring shape, a plurality of salient pole sections that protrude and extend radially from the common connection section, each of the salient pole sections defining a common connection section side adjacent to the common connection section and a tip side opposite the common connection section side, and a coil winding wound on each of the salient pole sections. The coil winding is wound on each of the salient pole sections in a plurality of layers, and each of the salient pole sections includes a retaining section adjacent to the tip side thereof, which hooks and supports a lead wire that extends from a winding end part of the coil winding.Type: GrantFiled: April 25, 2003Date of Patent: November 22, 2005Assignee: Sankyo Seiki Mfg. Co., Ltd.Inventors: Masato Gomyo, Noboru Ashibe

Patent number: 6939047Abstract: A dynamic pressure bearing device includes a rotary shaft, a dynamic pressure bearing member for supporting the rotary shaft, two radial dynamic pressure bearing parts and a thrust dynamic pressure bearing part formed between the dynamic pressure bearing member and the rotary shaft, and a lubricating fluid continuously filled in the two radial bearing parts and the thrust bearing part. A bypass passage for pressure release is provided for communicating across the two radial dynamic pressure bearing parts to flow the lubricating fluid corresponding to the amount of the unbalance caused by the unbalance of the pumping effect forces from a high-pressure side to a low-pressure side through the bypass passage to reduce the unbalance.Type: GrantFiled: June 5, 2003Date of Patent: September 6, 2005Assignee: Sankyo Seiki Mfg. Co., Ltd.Inventors: Masato Gomyo, Noboru Ashibe
