Abstract: An apparatus for inspecting a semiconductor device according to an embodiment includes an X-ray irradiation unit configured to make monochromatic X-rays obliquely incident on the semiconductor device, which is an object at a predetermined angle of incidence, a detection unit configured to detect observed X-rays observed from the object using a plurality of two-dimensionally disposed photodetection elements, an analysis apparatus configured to generate X-ray diffraction images obtained by photoelectrically converting the observed X-rays, and a control unit configured to change an angle of incidence and a detection angle of the X-rays, in which the analysis apparatus acquires an X-ray diffraction image every time the angle of incidence is changed, extracts a peak X-ray diffraction image, X-ray intensity of which becomes maximum for each of pixels and compares the peak X-ray diffraction image among the pixels to thereby estimate a stress distribution of the object.

Abstract: A computer-readable recording medium having stored herein a program for causing a computer to execute a dental prosthesis design process includes: searching a database storing data including structures of teeth including natural teeth to search for candidate teeth, which correspond to a part where a prosthesis is to be mounted on, based on information of a shape surrounding the part where the prosthesis is to be mounted on; putting priority levels on the candidate teeth by applying a predetermined rule to a matching degree of the searching; and outputting information of the candidate teeth based on the priority levels.

Abstract: A normal vector or a curvature at each of a plurality of vertexes that are included in data relating to an oral cavity shape including a tooth crown shape of at least one tooth and define the oral cavity shape is acquired. Then, a vertex group that defines the tooth crown shape of the at least one tooth is extracted from the plurality of vertexes based on the acquired normal vectors or curvatures. Further, the extracted vertex group is outputted as tooth crown shape information that specifies a tooth crown portion in the oral cavity shape. Consequently, automatic construction of a database for a tooth crown shape can be implemented.

Abstract: A movable table positioned to a predetermined position with respect to a base through manual movement, fixed to the base after the positioning. A lift mechanism that releases a top plate from a fixed state and lifts the top plate from the base against an attraction force of a magnet, or against the attraction force and the gravity of the magnet, and a mechanism that lowers the top plate from a predetermined lifted position with either or both the attraction force or the gravity of the magnet, and fixes the top plate to the base with an action of the attraction force of the magnet.
