    • In a hydrodynamic bearing device in which a radial bearing face having a dynamic pressure generating groove on a shaft or an inner periphery of a sleeve is provided and a clearance between the shaft and the sleeve is filled with lubricant, an annular depression is provided on one end face of the sleeve adjacent to a rotor hub and a cover plate for covering the depression is attached to the sleeve so as to define a reservoir for the lubricant or air for the purpose of preventing such a risk that absence of an oil film occurs in clearances of a bearing of the hydrodynamic bearing device due to outflow of oil upon forcing of the oil by air received into the bearing. A step portion is provided on the other end face of the sleeve such that the step portion and the reservoir are communicated with each other by a communication hole. During operation of the hydrodynamic bearing device, air in the hydrodynamic bearing device reaches the reservoir via the communication hole so as to be discharged from the reservoir.

    • When operating a database management system that consists of a plurality of database servers and enables the database servers to transfer data between them by partitioning a data area into small areas and altering allocation of the small areas to the database servers, after altering the configuration, there occurs degradation in processing speed that accompanies re-creation of the index. If this problem is solved by using the conventional technique, noticeable degradation in processing speed will occur to a specific query at the time of a steady state operation. When operating the database management system that consists of the plurality of database servers and enables the database servers to transfer data between them by partitioning the database area into small areas and altering the allocation of the small areas to the database server, an index created for each of the small areas and an index to all the small areas allocated to the database server are used in combination.
    • 当操作由多个数据库服务器组成的数据库管理系统并且使数据库服务器能够通过将数据区域划分成小区域并且将小区域的分配改变到数据库服务器来在其间传输数据时,在更改配置之后, 伴随重新创建索引的处理速度发生降级。 如果通过使用传统技术解决了这个问题,则在稳定状态操作时,特定查询将发生处理速度明显的下降。 当操作由多个数据库服务器组成的数据库管理系统并且使数据库服务器能够通过将数据库区域分割成小区域并且将小区域的分配改变为数据库服务器来传输数据时,为每个数据库服务器创建一个索引 的小区域和分配给数据库服务器的所有小区域的索引组合使用。

    • A liquid crystal display module including a liquid crystal display having a plurality of liquid crystal cells, a plurality of switches and a common connection, each liquid crystal cell being connected between a respective switch and a common connection. The common connection includes strips, each extending in a first direction and the strips being arranged side-by-side in a second direction. The liquid crystal cells are arranged in rows, each row being along and connected to a strip. The liquid crystal display has gate lines, each gate line operating a respective plurality of the switches. For dot inversion, each gate operates switches connected to respective liquid crystal cells of two adjacent rows. For each row, a first set of alternate liquid crystal cells are connected to respective switches operated by a respective gate line and a second set of interspersed liquid crystal cells are connected to respective switches operated by another respective gate line.
