摘要： PURPOSE:To efficiently obtain the cross section shape of a solid by providing a means to store the information of the solid, a means to designated the cutting surface of the solid, a means to calculate the cross section shape and a displaying means to display the calculated cross section shape, etc. CONSTITUTION:A solid information memory means 2 controls the shape information of surfaces constituting the solid and the displaying information for the solid and the surface, and a displaying means 5 displays the surface constituting the solid by the shape of the surfaces constituting the solid and its attribute information. A cutting surface designating means 3 generates cutting surface information based on inputted designating information, and a cross section shape calculating means 4 generates the shape of the left surface without being cut by the cross section shape and the cutting surface based on the cutting surface information and surface shape information. The displaying means 5 displays the cross section shape and the corrected surface shape again. Thus, the arbitrary cross section shape of the solid and a condition inside the solid can be displayed.

摘要： PURPOSE:To record and reproduce the different types of information via the same recording medium by recording the digital TV picture information, the digital voice information, the object information transformed into a language, etc., onto the same recording medium and discriminating these information after reproduction. CONSTITUTION:The object information on a 3-dimensional position transformed into a language as well as the compressed digital TV picture information and the digital voice information are recorded on the same recording medium. These recorded information are read by a recording medium reading part 11 and a language transformation data deciding part 12 decides the recording contents are equal to the language data or not. If not, the read data is expanded and restored by an information restoring part 14 via one of two changeover switches 13 and delivered via a D/A converter 16. While the language data is stored in a language data memory 17 via the other switch 13 and converted into the digital picture data via a position information converting part 19, a language raster converting part 20, etc., to be stored in a picture memory 15. Thus the different types of information like the digital information, the language information, etc., are recorded and reproduced via the same recording medium.

摘要： PURPOSE:To reduce fluctuation of density and to improve the quality of recorded picture, by making a mask for printing the lowest glaze layer wider than a mask for printing a layer upper than second layer. CONSTITUTION:Since the limit of human eye for discriminating the density is about 0.02, the height difference between the top and bottom must be less than 1mum with 2mm margins at the opposite sides of a dot on the top portion of a glaze layer. The lowest glaze layer 2a is printed through a mask of 0.95mm, for example, onto an insulating substrate 1. Then second and following glaze layers 2b are printed through a mask of 0.8mm width, for example. When drying and sintering are carried out after screen printing, the self-weight of glass the surface tension of the insulating substrate 1 and glass cause spreading of glass to the foot portion, but when the lowest glaze layer 2a is made wider than the second and upper glaze layers 2b-2f, flow-out of glass can be prevented.

摘要： PURPOSE:To enable multiple gradation middle tone recording imparting excellent printing quality, by using a thermal head capable of performing middle tone recording and a middle tone transfer sheet capable of controlling a transfer ink amount and continuously controlling the state of a recording dot regenerated on transfer paper. CONSTITUTION:In a middle tone recording thermal head 31, a heat generating resistor 2 is constituted of resistor elements 2a, 2b, 2c each having a rectangular parallepiped different in an applying energy value per a unit area and arranged on a substrate 1 in an array form to be connected to an electrode 3. Power is sent to said electrode 3 corresponding to an image signal and the energy applied to the heat generating resistor 2 is controlled to regenerate a variable density image 36 on transfer paper 34. A middle tone transfer sheet 9 consists of a base film 10 and an ink layer 11 and is held between a thermal head 12 and the transfer paper 13 at the time of recording and, because the amount of the ink 15 transferred to the transfer paper 13 is little and the thickness thereof is reduced when the quantity of generated heat of the thermal head 12 by the current of a heat generating resistor 14 is low, a low density dot is formed and, when the quantity of generated heat increases, a high density dot is formed.

摘要： PROBLEM TO BE SOLVED: To provide a semiconductor device capable of sufficiently improving surface withstand voltage and achieving higher voltage and miniaturization. SOLUTION: An insulating plate 2 is disposed on one surface of a base substrate 1. A circuit side conductor 3 is provided on the other surface of this insulating plate 2 via a metallic layer 4. There is provided a semiconductor element 5 on this circuit side conductor 3. In this semiconductor device for power, a recessed portion 20 having a curved surface on peripheral end portions is formed in the insulating plate surface 2 in advance. By forming the metallic layer 4 in this recessed portion 20, the end portions of the metallic layer 4 become curved. Since the end portions of the metallic layer 4 do not have corner portions, electric field can be relaxed at the end portions of the metallic layer 4 where the electric field is easily most concentrated, and thus the surface withstand voltage of the insulating plate can be improved.
