    • 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.

    • The conventional technologies are impractical for the following reason. CAD has been the only solution for changing an analysis model with adding or deleting a fillet. In this case, it is necessary to repeat the mesh generation and condition configuration, which makes the work time longer especially for large-scale or complicated shape data. The present invention, accomplished to solve the above-mentioned problem, provides an analysis mesh generation apparatus including a computer for generating a mesh model. The apparatus is configured to create a screen for selecting an edge of a mesh model and entering a radius of a fillet to be applied to the selected edge; and to create a screen for generating a mesh for the applied fillet, generating a new mesh model by deleting or adding an area enclosed by a contour of the mesh model and the fillet, and displaying the new mesh model.
    • 传统技术是不切实际的,原因如下。 CAD是通过添加或删除圆角来更改分析模型的唯一解决方案。 在这种情况下,需要重复网格生成和条件配置,这使得工作时间更长,特别是对于大规模或复杂的形状数据。 为了解决上述问题而实现的本发明提供了一种包括用于生成网格模型的计算机的分析网格生成装置。 该装置被配置为创建用于选择网格模型的边缘并输入要应用于所选边缘的圆角的半径的屏幕; 并创建用于生成应用圆角的网格的屏幕,通过删除或添加由网格模型和圆角的轮廓包围的区域并显示新的网格模型来生成新的网格模型。

    • An electric shaver comprises a housing (1) formed as a grip, a shaving head (2) comprising at least one cutting unit (11) having an outer cutting member (16) and an inner cutting member which is rotatable relative to the outer cutting member, and drive element for driving the inner cutting member, the shaving head being pivotably connected to the housing. In known shavers the motor is accommodated in the shaving head, resulting in a poor balance and poor contact between the shaving head and the skin. According to the invention the shaver is characterized in that a motor (5) belonging to the drive element is accommodated inside the housing (1), the drive element being adapted to follow the pivotal movements of the shaving head (2) relative to the housing. Preferably, the drive element comprises flexible coupling element, for example a pulley-belt transmission (9, 12, 15) but alternatively the drive element may comprise a universal joint.
