Abstract: To provide a database which has plural log storage areas, and eliminates the sort in the restoration process by means of the application of logs, thereby carrying out the restoration quickly. A management server allocates DB servers to a corresponding one of plural data storage areas so as to access the corresponding one. The DB servers store data to the allocated data storage areas. When the data is referenced or updated, a log representing a data change history is stored in preset log areas for each data server. When the management server transmits a notification to change the data storage areas, area remapping logs are stored in log areas.

Abstract: There is provided a hydrodynamic bearing device that maintains high bearing angular stiffness, and that prevents oil film separation in the bearing by smoothly discharging any bubbles present inside the bearing. With a hydrodynamic bearing device, a communicating hole and a radial hydrodynamic groove constitute a circulation path for a lubricant, and a first thrust bearing surface is provided at a location in contact with the circulation path. A first hydrodynamic groove formed in the first thrust bearing surface is a spiral groove with a pump-in pattern. Any bubbles in the bearing are smoothly discharged by the circulation of the lubricant produced by the asymmetrical radial hydrodynamic groove. The pressure generated at the thrust bearing surface during rotation of the bearing has a distribution such that there is a wide range of high pressure.

Abstract: To prevent air from being trapped inside a bearing and causing the bearing to have oil film rupture and NPPR to deteriorate. A flange having a shape substantially like a disc is provided integrally with a shaft near its lower portion. A sleeve having a bearing hole is fitted to the shaft so as to be relatively rotatable. Hydrodynamic grooves are provided on at least one of an outer periphery of the shaft and an inner periphery of the sleeve. The flange forms a thrust bearing surface with a lower end surface of the sleeve. Hydrodynamic grooves are provided on at least one of the lower surface of the sleeve and an upper surface of the flange. During rotation of the bearing, the hydrodynamic grooves circulate the lubricant. Capillary pressures at respective portions in the lubricant circulation path have difference in magnitudes. The principle that air tends to move toward the portion having a smaller capillary pressure is utilized to make it difficult for the air to be trapped inside the bearing and to smoothly discharge the air.
