Title: Inspecting for design rule
Inventor: IWATSUKI MAMORU
IPC: G06F17/50
Filed: 1990-02-17
Abstract: PURPOSE:To prevent the generation of false design error recognition by storing the configuration features of a contact hole region, which must not be recognized as a design error, comparing the configuration features, which is recognized as a design error by a design means, with the aforesaid features, and adopting a structure to nullify the recognition of design error when both agree with each other. CONSTITUTION:A design error recognition section of a design tool check device in a CAD system, for example, detects a lapped portion of a contact hole region and a wiring layer region. It detects every width of the contact holes when the lapped portions exceed 2, compares the detected values with the allowable minimum value, and recognizes and displays if they are less than the minimum value. A graphic feature file 3 is prepared with the number of apexes and change in the direction of a vector which connects the apexes as for the configuration which must not be recognized as a design error. A recognition nullification section 42 detects the number of apexes and vector data in the contact hole region which is recognized as design error by the design error recognition section 41, and compares the detected data with the num ber of apexes and vector data read from the file 33, and nullifies the error recognition and error display by the design error recognition section 41 when both agree with each other.

Title: Production of glazed concrete panel
Inventor: KITAGAWA SATOSHI
IPC: B28B1/14
Filed: 1990-02-17
Abstract: PURPOSE:To inhibit formation of hydrate and to obtain an excellently glazed face after burning by placing kneaded cement in a form and thereafter holding the product of curing time and curing temp. in the form within the specified range. CONSTITUTION:Form removal is performed in an early stage within a range capable of handling by controlling the curing conditions of kneaded cement in a form. The state of water retention on the surface of concrete is shortened. When the curing temp. and the curing time are defined as C ( deg.C) and T (hour) respectively, the curing conditions are regulated so as to satisfying the following range, 180 deg.C.hour<=C.T<=480 deg.C.hour. For example, when the temp. curing is performed at 60 deg.C, the curing time is necessarily regulated to a range within 3 - 8 hours. Since hardening of kneaded cement is made insufficient in the case of C.T less than 180( deg.C.hour), handling of a molded cement body is made impossible. On the other hand, when C.T exceeds 480 ( deg.C.hour), formation of hydrate is made plenty and an excellently glazed face can not be obtained.
