Patent number: 9799368Abstract: A fluid-dynamic bearing system comprising a stationary bearing component (12, 16, 18) and a bearing component (14, 14a) rotatable about a rotation axis, wherein, during operation of the bearing, the stationary and rotary components are separated from each other by a bearing gap (20) filled with a bearing fluid, wherein at least one fluid-dynamic radial bearing (22, 24) and at least one fluid-dynamic thrust bearing (28) or, alternatively, at least one conical fluid-dynamic bearing are arranged along the bearing gap (20), and wherein the bearing gap (20) comprises first and second open ends sealed by a first sealing gap (34) and a second sealing gap (36). The second sealing gap (36) exclusively extends normal to the rotation axis (40).Type: GrantFiled: October 5, 2015Date of Patent: October 24, 2017Assignee: MINEBEA CO., LTD.Inventors: Thomas Fuss, Tobias Kirchmeier, Oliver Vogt

Publication number: 20160374124Abstract: Embodiments include an implantable medical device (IMD) that includes a control unit, a permanent memory for a device identifier IID, a memory unit that stores a device identifier EID of an external device, a near-field data communication unit and a far-field data communication unit. The control unit, jointly with the near-field data communication unit, detects a third device in the near-field region of the IMD and transmits the device identifier IID of the IMD to the third device. The control unit, following a near-field data communication with a third device, checks any messages received via the far-field data communication unit as to whether the messages include a far-field start message and a device identifier IID of the IMD that corresponds to the device identifier stored in the permanent memory. The control unit sends a far-field response message, which includes the device identifier IID and the device identifier EID.Type: ApplicationFiled: June 8, 2016Publication date: December 22, 2016Applicant: Biotronik SE & Co.

Patent number: 9033580Abstract: The fluid dynamic bearing system has at, least one stationary part, and at least one rotating part that is supported rotatable about a rotational axis with respect to the stationary part. A bearing gap filled with bearing fluid is formed between mutually opposing surfaces of the stationary and of the rotating part. The bearing system includes at least one fluid dynamic radial bearing and at least one fluid dynamic axial bearing that are disposed along sections of the bearing gap. In one aspect of the invention, an annular sealing gap for sealing open ends of the bearing gap has one end connected to the bearing gap and one end connected to an annular reservoir, the outside radius of the reservoir measured from the rotational axis being larger than the outside radius of the sealing gap.Type: GrantFiled: December 3, 2013Date of Patent: May 19, 2015Assignee: MINEBEA CO., LTD.Inventors: Thomas Fuss, Martin Engesser, Atsushi Yanagawa, Werner Schmid, Carsten Etling

Patent number: 8737019Abstract: The invention relates to a spindle motor that comprises a stationary motor component having a shaft and an annular stopper part disposed at a free end of the shaft as well as a rotatable motor component that is rotatably supported by means of a fluid dynamic bearing system with respect to the stationary motor component. The rotatable motor component is driven by an electromagnetic drive system. A housing cover covers the spindle motor. The invention is characterized in that the shaft has a step on which a stopper part rests, the end face of the stopper part projecting axially beyond the end face of the shaft, and the housing cover resting only on the end face of the stopper part but not on the end face of the shaft.Type: GrantFiled: August 15, 2013Date of Patent: May 27, 2014Assignee: Minebea Co., Ltd.Inventor: Thomas Fuss
