IPC: B22D11/04
Filed: 1988-06-29
Abstract: PURPOSE:To reduce temp. variety to casting direction in a mold and to restrain inclination of the temp. to small by gradually increasing area in crossing sectional plane to the casting direction of cooling water passage in inner face of the mold. CONSTITUTION:The cooling water passage 3 formed in inner part of copper plate 1 has shape, which the width is gradually widened toward the casting direction and the depth is gradually deepened toward the casting direction, that is, the passage 3 is formed so that the area at the crossing sectional plane to the casting direction is gradually increased. By this construction, coefficient of heat transfer for cooling water is varied over the casting direction and in the copper plate 1, the high temp. part to the low temp. and/or the low temp. part to the high temp. are changed. Therefore, the temp. inclination is little and acts to tendency of restraining the development of strain in the copper plate 1. Further, the development of crack can be avoided.

Abstract: PURPOSE:To decrease the voltages to be applied on the insulating layers at the points where members come into contact with each other via insulators to a lower value by providing a plurality of the bending points in the energization circuit of a self-heat generation type catalyst carrier. CONSTITUTION:A metallic plate consisting of a flat plate 2 and corrugated plate 3 carrying catalysts is bent and is housed in a honeycomb shape into a case. The corrugated plate 3 and the flat plate 2 are connected in series at this time and bending points 5, 6 exist. The voltage E applied at the terminals of both ends is E1+E2. The bending points have the high probability that the insulating layer is broken by the contact between the members via the insulator at one point in the central part but if the bending points exist n-pieces, the voltage is the sum of the voltages applied at the respective bending points. Then, the voltages at the points where the members come into contact via the respective insulators can be made lower than the voltage impressed to the catalyst carrier itself.

Filed: 1987-06-30
Abstract: PURPOSE:To make it possible to accurately conduct mark-matching work for the following process by a method wherein, among the patterns used when a buried diffusion work is conducted, the amount of change of the matching mark caused by the epitaxial growth of the next process is computed in advance, and the amount of change is then corrected. CONSTITUTION:A correction process is introduced in such a manner that only the matching mark, used when a buried diffusion work is conducted, is corrected in the amount of change caused by the epitaxial growth with leeway. To be more precise, even when the measurement of the matching mark used when a buried diffusion work is conducted are changed by the epitaxial growth, the correction measurement corresponded to the amount of change is computed in advance. Accordingly, when superposed on the mark matching pattern after the epitaxial growth, a matching mark pattern can be obtained as computed after the epitaxial growth. As a result, the matching mark pattern as the design can be obtained after epitaxial growth.
