A predetermined sound interval interlocking mechanismfor making opening and closing operations of sound hole coversof an existing sound range interlock with opening and closing operations of sound hole coversof an expanded sound range is provided and a sound hole switching mechanism capable of collectively closing the sound holes of the high-pitched range by one key operation is provided independent from the predetermined sound interval interlocking mechanism. By using the above described mechanisms, both ranges can be played only by the operation of selecting the sound range and operating the sound hole coversof the existing sound range. In addition, a slide platesliding along an inner surface of the tube for forcibly opening and closing the sound holesfrom the inside of the tube is proposed as the sound hole switching mechanism.

This art can manage a preparation history of a transaction document and a send and receive history by EDI in a centralized manner. When the transaction document and the version are selected and attached to the EDI data, then the EDI data is sent, a means that links a document management means and an EDI means registers sending information of the EDI data in version control information of the relevant transaction document.

Database optimizing method and system are provided to optimally locate data. Only data satisfying conditions desired by a user is extracted among an access log. Values of a part of the data are translated on the basis of a translation table, and aggregated on the basis of aggregation condition rules. The obtained aggregation result is presented to the user. In addition, data in the database are optimally relocated on the basis of the obtained aggregation result.

Database management program, a database managing method and an apparatus therefor

A shape model as an object to be analyzed and division information used to produce a finite element mesh are entered, and a recognition model is produced by allocating each edge line segmented by structural points of the shape model to any one coordinate axial direction in an orthogonal coordinate system. A mapping model is produced in which an orthogonal lattice is produced on a surface and the inside of an approximated shape model, and is displayed on a screen. The mapping model is modified by a system user in an interactive operation. A finite element mesh is generated from lattice points of the modified mapping model. The data input by the system user is processed in an input/output data processing unit, and shape model data of the object to be analyzed is produced in a shape model producing unit. Based on the division information input by the system user, a finite element mesh is generated on the shape model by a finite element mesh producing unit. The line segment allocation directions of the recognition model are displayed in a recognition model producing unit, so that an allocation direction can be modified in a recognition model modifying unit by the system user in a interactive mode. The finite element model data produced from the optimized recognition model is registered into a database.

Sub-areas divided from a three-dimensional areas to be analyzed are generated by hexahedron meshes as much as possible, and for the sub-areas not formed by the hexahedron elements, tetrahedron meshes are generated by a tetrahedron mesh generation unit. For the mesh generation of the sub-area adjacent to the hexahedron mesh area and the tetrahedron mesh area, the data of other sub-area for which the mesh has been generated which is adjacent to the sub-area for which the mesh is to be generated is searched from a sub-area data area and a mesh shape formed by a plurality of triangles on the surface of the area for which the mesh is to be generated from the mesh shape on the joining plane to the adjacent sub-area to generate a quadrilateral mesh in the area for which the mesh is to be generated.
