    • In a cache memory management device, a time measuring unit measures a time period required to obtain data from a database. The data obtained from the database is linked to the time information and both are stored in a data cache unit. If the data cache does not have sufficient room to store the data obtained from the database, a data replacement determination is made. In one embodiment, the data is replaced by referring to the total data access time. In a second embodiment, if a statistics processing unit judges that the access time and the size of each data are proportional to each other, then cache data is replaced by referring to the size information from a size calculation unit. If, however, the statistics processing unit judges that the access time and the size of each data are not proportional to each other, cache data is replaced by referring to the time information from the time measuring unit.
    • 在高速缓冲存储器管理装置中,时间测量单元测量从数据库获得数据所需的时间段。 从数据库获得的数据链接到时间信息,并且两者都存储在数据高速缓存单元中。 如果数据高速缓存没有足够的空间存储从数据库获得的数据,则进行数据替换确定。 在一个实施例中,通过参考总数据访问时间来替换数据。 在第二实施例中,如果统计处理单元判断每个数据的访问时间和大小彼此成比例,则通过参考来自大小计算单元的大小信息来替换高速缓存数据。 然而,如果统计处理单元判定每个数据的访问时间和大小彼此不成比例,则参考来自时间测量单元的时间信息来代替高速缓存数据。

    • Provided is a method that, in the case of managing areas of a non-volatile memory of an information recording module by a file system, increases the speed of processing for writing file data and file system management information, and furthermore prevents a decrease in the rewriting lifetime of the non-volatile memory. The information recording module (2) is provided with a page cache control unit (217) that stores page cache information (224) in the non-volatile memory (22) of the information recording module (2) and performs control such that a specific physical block is used as a cache when writing small-sized data. Also, an access module (1) is provided with a page cache information setting unit (104) that sets information necessary for page cache control in the information recording module (2). The combination of the access module (1) and the information recording module (2) prevents the execution of needless saving process with use of page caching when writing small-sized data, thereby increasing the speed of writing processing.
    • 提供了一种在通过文件系统管理信息记录模块的非易失性存储器的区域的情况下增加用于写入文件数据和文件系统管理信息的处理速度的方法,并且进一步防止 重写非易失性存储器的使用寿命。 信息记录模块(2)设置有页面缓存控制单元(217),其将页面缓存信息(224)存储在信息记录模块(2)的非易失性存储器(22)中,并执行控制,使得特定 当写入小尺寸数据时,物理块用作缓存。 此外,访问模块(1)具有在信息记录模块(2)中设置页面缓存控制所需的信息的页面缓存信息设置单元(104)。 访问模块(1)和信息记录模块(2)的组合在写小尺寸数据时防止使用页面缓存来执行不必要的保存处理,从而提高写入处理的速度。

    • Provided is a chair suited to the use of a keyboard or mouse, the chair has a seat 3 and a rocking backrest 4. The seat 3 comprises a first section 3a, 12a and a second section 3b, 12b. The first section 3a of the seat 3 is affixed to a seat-mounting shell 11 is attached to a base 9, via a seat-mounting fixture, so as to be slide forwards and backwards. The backrest 4 has a back cover 14, a back panel 15 and a cushion move downwards while rotating in a seesaw fashion during rocking. The front end of the back cover 14 is connected to the seat-mounting fixture 10 by means of a connecting pin 25. When the chair rocks, the seat 3 moves forwards as a whole while the second section 3b tilts backward.

    • An information recording device, which includes a nonvolatile memory whose areas are managed using an FAT file system and enhances the reliability of directory entries using a cyclic shift checksum, recalculates the cyclic shift checksum efficiently and performs seeking at a higher speed. A nonvolatile memory (25) of an information recording device 2 is managed using an FAT file system. In the memory, a plurality of directory entries are allocated to a single file. The device enhances the reliability of the directory entries using a cyclic shift checksum, and manages information indicating the position and the size of a storage area of file data using an extent information entry (203). The device further uses an update information entry (204) and a dummy entry (205).
