Title: Scale modifier easy of peeling for ferrous slab
Inventor: KITAYAMA MINORU
IPC: C21D1/70
Filed: 1990-02-07
Abstract: PURPOSE:To improve the peeling characteristic of scale occurring at the time of heating in the hot and warm workings of a steel plate by incorporating the powder of specific metals, such as zinc, iron, and Al, easily forming iron oxide and multiple oxide in an oxidation stage or the powder of alloys thereof. CONSTITUTION:This modifier contains the powder of metals easily forming iron oxide and multiple oxide in an oxidation stage or the powder of alloys thereof and a powder mixture, and further, the above powdered metals are selected from zinc, iron, Al, lead, tin, Sb, Zr, Si, Bi, Sr, and Mn. This modifier is a coating agent which contains the above powdered metals and also contains a resin easily formed into a film with superior adhesive strength at the time of coating at ordinary temp. and easy of complete combustion at 120-500 deg.C. By using this modifier, at the same time as the steel plate is drawn out from a heating furnace and its temp. begins to fall, the scale is immediately peeled off from the whole surface or the greater part of the surface owing to the difference in shrinkage between iron and the scale part, and further, even if residual scale parts exist, they can be easily and completely peeled off by a slight impact.

Title: Method for calculating positional distortion of pattern
Inventor: ODA MASATOSHI
IPC: G03F1/22
Filed: 1996-02-14
Abstract: PROBLEM TO BE SOLVED: To simulate the positional shift of a pattern formed on an absorbing body more easily 'by calculating the displaced state of pattern while assuming that the absorbing body has film thickness distribution corresponding to the density distribution of pattern. SOLUTION: Assuming that a punched pattern and a boundary are not present in a region for calculating distortion but the film thickness is decreasing uniformly over the entire area, a differential equation for balance can be solved very easily without employing a boundary condition formula. When this method is employed, any intricate pattern can be handled as a variation of film thickness corresponding to the density so long as the density is known. Displaced state of pattern is calculated assuming that the absorbing body has film thickness distribution corresponding to the density distribution of a pattern to be formed thereon. Consequently, the positional shift of pattern can be simulated more easily even for an intricate pattern without requiring an intensive labor for obtaining a solution.
