摘要： A fluid dynamic bearing mechanism includes a stationary bearing portion including a sleeve portion, and a rotating bearing portion including an outer rotating portion. A lubricating oil is arranged between the stationary and rotating bearing portions. A first dynamic pressure groove array is arranged in an upper surface of the sleeve portion or a lower surface of the outer rotating portion. A second dynamic pressure groove array is arranged in a surface of the outer rotating portion or a surface of the stationary bearing portion in a region between the first array and a liquid surface. An end of the second array closer to the liquid surface is arranged radially inward of an opposite end of the second array. An upper end opening of a communicating channel defined in the sleeve portion is arranged radially outward of a radially inner end of the first array.

摘要： 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. In addition, a flow of the lubricating oil into the third minute gap caused by a centrifugal force accompanying rotation is inhibited.
摘要翻译：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。此外，抑制由伴随旋转的离心力引起的润滑油流入第三微小间隙的流动。

摘要： When a volume belonging to a first storage tier is relocated to a second storage tier, in the event that an empty volume satisfying capacity conditions is not present in the second storage tier, an empty volume satisfying the capacity conditions within volumes belonging to a third storage tier is virtually allocated to the second storage tier, a further virtual empty volume is formed, and the volume is virtually relocated to the further virtual empty volume.

摘要： In the conventional storage system, consistency is ensured only for writing from a single storage. Asynchronous remote copying and local replication are also alternately suspended in the conventional system, so that the suspension time increases and the volume in which consistency is obtained becomes old. Two local replicas are prepared, for a volume containing stored data that is transferred from the main site by asynchronous remote copying, in the storage at the sub-site. Each pair of local replicas is alternately suspended by a time-specific suspension command according to the time of the timestamp attached to the write data, and replica data in which the time sequence is secured is continually prepared. When a failure occurs at the main site, the data is recovered using the replica data.

摘要翻译：在传统的存储系统中，只能从单个存储器写入一致性。异常远程复制和本地复制也在传统系统中交替挂起，使得暂停时间增加，并且获得一致性的容量变得较旧。对于包含从主站点通过异步远程复制传输的存储数据的卷，在子站点的存储中准备了两个本地副本。根据附加到写入数据的时间戳的时间，通过时间特定的暂停命令交替地暂停每对本地副本，并且连续地准备其中确保时间序列的副本数据。当主站发生故障时，使用副本数据恢复数据。

摘要： A semiconductor integrated circuit is segmented into a plurality of blocks. Each block includes a switching transistor which is connected between the CMOS circuit of the block and the ground point and is adapted to shut off the current of the CMOS circuit by being controlled by a test mode control signal, and a leakage current detecting circuit which has a self-check function for the block. A signal which is the logical sum of the outputs of the leakage current detecting circuits of all blocks is led out of the semiconductor integrated circuit through a common external output terminal.
