    Abstract: A fluid dynamic bearing apparatus includes a first minute gap, a second minute gap, a third minute gap, a fourth minute gap, and a fifth minute gap. A flow of a lubricating oil from the fifth minute gap to the fourth minute gap is caused by a plurality of dynamic pressure generating grooves arranged within the fluid dynamic bearing apparatus. This flow causes air bubbles mixed in the lubricating oil within the fifth minute gap to flow toward the third minute gap and be discharged to an outside through the third minute gap. The fluid dynamic bearing apparatus further includes a plurality of dynamic pressure generating grooves and an all around groove.

    Abstract translation: 流体动力轴承装置包括第一微小间隙，第二微小间隙，第三微小间隙，第四微小间隙和第五微小间隙。 润滑油从第五分钟间隙到第四微小间隙的流动由布置在流体动力轴承装置内的多个动压产生槽引起。 该流动使第五分钟间隙内的润滑油中混合的气泡朝向第三微小间隙流动，并通过第三微小间隙排出到外部。 流体动力轴承装置还包括多个动压产生槽和全周围槽。

    Abstract: A fluid seal for sealing a gap region for rolling elements rotationally connecting a shaft and an outer structure of a rotating assembly. In embodiments described, the fluid seal includes an inner capillary seal and an outer capillary seal radially and axially spaced from the inner capillary seal. The inner and outer capillary seals are formed along a passageway having an axial portion and a radial portion formed along capillary surfaces of a fluid seal structure and opposed transverse and upright surfaces. In embodiments disclosed, the fluid seal structure includes a seal ring and cap or a seal plate structure. In another embodiment, a flange portion of the shaft forms the fluid seal structure.
