Abstract: A predetermined sound interval interlocking mechanism 7 for making opening and closing operations of sound hole covers 4 of an existing sound range interlock with opening and closing operations of sound hole covers 4 of 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 7. 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 covers 4 of the existing sound range. In addition, a slide plate 9 sliding along an inner surface of the tube for forcibly opening and closing the sound holes 3 from the inside of the tube is proposed as the sound hole switching mechanism.

Abstract: When registering a document, notify a document registrant of related information of one or more documents similar in content thereto. In addition, upon registration of the document, if a folder is designated as a registration destination thereof then notify the document registrant of relevant information of any available similar documents which reside within the registration destination folder. This permits users to effortlessly recognize and grasp useful relevant information through information publication. This in turn makes it possible to provide users with motivation for progressive or “positive” participation in common sharing of information and knowledge.

Abstract: 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.
