摘要： There is provided a nondestructive method for inspecting ceramic structures, the method which not only easily detects the position and size of an internal defect in a ceramic structure in a short time, but also accurately identifies the position, shape, and size of the internal defect. In the method, the distribution of X-ray absorption coefficients (CT numbers) at fault planes of the ceramic structure is measured by irradiating the periphery of the ceramic structure with X rays along the periphery of the ceramic structure so that the X rays scan the entire periphery. The X rays are emitted from an X-ray tube at a tube voltage in the range of 80 to 400 kV and a tube current in the range of 2 to 400 mA.

摘要： There are repeated the step of isotropically etching an oxide film (12) formed over the surface of a semiconductor substrate (11) through an opening (12a) to form a recess (11a), the step of anisotropically etching an oxide film (14) formed on the inner face of the recess to form an opening (14a), and the step of isotropically etching through the opening to form a recess (11b) succeeding to the recess (11a) through the opening (14a). A deep gate structure can be achieved within a short time while eliminating the overlapping errors of a mask, by using the overhangs of the openings formed in the oxide films (12, 14, 15 and 16) as the mask in all the following etching steps to repeat the isotropic and anisotropic etching steps through the same mask. The sectional shapes of the recesses are formed of a plurality of curved surfaces having different curvatures. It is possible to achieve a semiconductor device having recesses of a large aspect ratio (i.e., length/width ratio), i.e., of a larger depth than an opening width.

摘要： This invention provides a method of firing a ceramic honeycomb structure which comprises varying the oxygen concentration in a firing atmosphere in a temperature range where a molding aid and/or a pore forming material is difficultly burnt or in a temperature range where they are burnt, to inhibit abrupt heat buildup of the aid etc., increasing the oxygen concentration in the atmosphere in a temperature range where the pore forming material and/or the molding aid is difficultly burnt to promote their combustion so as to reduce the temperature difference between the internal and external parts of the honeycomb structure, and making uniform the internal and external characteristics without causing any crack inside and at the end parts of the honeycomb structure and without causing internal melt loss. In this manner the method of the invention enables satisfactory firing. Moreover, since it is not necessary to reduce the firing rate, the firing schedule can be shortened and production efficiency can be improved. Accordingly, the present invention is particularly effective for a ceramic honeycomb structure.
