Abstract: PROBLEM TO BE SOLVED: To reduce the longitudinal crack caused by insufficient flowing of molten powder into a gap between a mold and a solidified layer and to enable casting of a high quality cast slab by providing a scheme for electrically conducting so as to make the negative pole at the upper part of the molten powder near the mold and the positive pole at the molten steel side and supplying DC current having a specific voltage. SOLUTION: The high viscosity powder 4 is used and the device 5 for electrically conducting to the molten powder near the mold, is provided. The DC current is supplied so as to make the negative pole at the upper part of the molten powder 4 and the positive pole at the molten steel 10 side. As one of the most effective electrical supplying means, the electrode having the positive pole is used for the copper plate of the mold, but it is considered to use the other means, too. For high viscosity powder, the powder having >=1 Poise viscosity is assumed. The supplying voltage at the time of supplying the electricity to the molten powder is made 1-20 Volt. By this method, the entrapment of the molten powder can be prevented and the draft caused by the powder is reduced.

Filed: 1987-11-19
Abstract: PURPOSE:To facilitate the processing at replacement of a data base by obtaining an exclusive OR between the replaced and unreplaced data bases and acquiring and recording the result of said OR as a log. CONSTITUTION:The contents of a data base 10 of an initial state are all stored in a saving magnetic tape 13.

IPC: G03B7/28
Filed: 1989-11-10
Abstract: PURPOSE:To imprint a main object in the intermediate density area of film by controlling exposure based on the latest value stored in a storing means sequentially storing photometric values. CONSTITUTION:A spot photometry means 1 is subject to the photometry of the brightness of a specific part of a photographing screen and outputs a spot photometric value BVs. Whenever a manually operating switch 2 is operated, the value BVs is stored in the storing means 3 in order. Based on the latest value stored in the storing means 3, an exposure control means 4 controls exposure. If the brightness of a background is subjected to spot photometry and the value is stored as a 2nd stored value in the storing means 3, the exposure control means 4 controls exposure based on the 2nd stored value. Thus, exposure is controlled so that the main object has an intermediate density.
