Abstract: A database management program capable of restoring a use management book indicating allocation/non-allocation of data to individual unit storage regions, without the need to perform physical initialization at the time of reinitialization. When the database is initialized, all allocation flags provided in the use management book and indicative of allocation/non-allocation of data to the respective unit storage regions are set to a non-allocated state, and the value of an initialization counter indicative of the number of times the database has been initialized is updated. Each time data is allocated to one of the unit storage regions in the database, the allocation flag in the use management book corresponding to the data-allocated unit storage region is set to an allocated state, and the value of the initialization counter is set as an allocation-timed counter value associated with the data-allocated unit storage region.

Abstract: In a process for managing a plurality of data items contained in a plurality of pages which are sequentially arranged in accordance with predetermined relationships, information on an amount of available space in each of the plurality of pages is stored. When a first data item is inserted into or deleted from a first page among the plurality of pages, an amount of available space in each of second and third pages is acquired based on the above information, where the second page precedes the first page in the sequential arrangement of the plurality of pages, and the third page follows the first page in the sequential arrangement. Before insertion of the first data item into the first page or after deletion of the first data item from the first page, at least one second data item contained in the first page is moved to the second page or the third page according to the amount of available space in each of the second and third pages.

When the database is initialized, all allocation flags provided in the use management book and indicative of allocation/non-allocation of data to the respective unit storage regions are set to a non-allocated state, and the value of an initialization counter indicative of the number of times the database has been initialized is updated (S2). Each time data is allocated to one of the unit storage regions in the database, the allocation flag in the use management book corresponding to the data-allocated unit storage region is set to an allocated state, and the value of the initialization counter is set as an allocation-timed counter value associated with the data-allocated unit storage region (S3).

Abstract: A method for producing a mat including a three dimensional filament loop aggregate comprises extruding molten thermoplastic synthetic resin die to form a plurality of filaments. The filaments are heated and descend onto a surface of a cooling liquid, between a pair of rotatable rolls submerged in the cooling liquid. The filaments are all cooled simultaneously by the cooling liquid and form loops on the surface thereof. A first series of loops formed from outermost filaments are supported on one of the rotatable rolls in the cooling liquid, with the loops being horizontal. Rotation of the roll moves these loops into a vertical position. Thereafter, all the loops are integrated, with the loops formed by the outermost filaments being in a vertical position, and the loops formed by the remaining filaments being in the horizontal position.

Abstract: A method of producing a mat consisting of filament loop aggregations. The first step is that of forming a first filament loop aggregation low in the filament density wherein many filaments are made. These by extruding a thermoplastic synthetic resin out of a T-die and arranging the resin longitudinally and laterally at intervals for continuous molding. The resin is deposited on a boiling water surface. The filament temperature is maintained close to the temperature at the time of molding by heating while the filament bundle is vertically lowered toward a cooling water surface and is sunk into water in the vertical direction.
