Title: Denture stabilizing agent
Inventor: KANEMITSU TAKAMASA
IPC: A61K6/00
Filed: 1985-12-02
Abstract: PURPOSE:To provide a denture stabilizer easily removable from the denture after use, by using a partially saponified polymer containing vinyl acetate unit in the molecule as a component. CONSTITUTION:The objective denture stabilizer contains a polymer having a vinyl acetate unit of formula in the molecule, especially a copolymer of vinyl acetate unit and other units, e.g. copolymer of vinyl acetate and ethylene propylene, butene, acrylate or methacrylate.

Title: Device and method for processing image
Inventor: OSHINO TAKAHIRO
IPC: G06T3/40
Filed: 1995-10-19
Abstract: PROBLEM TO BE SOLVED: To smooth the equal-density linear shape as expected even in any multi-level image and to provide a magnified result having further higher picture quality. SOLUTION: A multi-level image inverting means S2 investigates the average density of input multi-level images, and when the average density is higher than a prescribed value, the input multi-level image is inverted. Then, the equal- density line is extracted for every density gradation of the multi-level image by an equal-density line outline smoothing/magnifying means S3, and that line is magnified to a designated magnification and smoothed. Based on the equal- density line, the multi-level image is reproduced by a multi-level image reproducing means S4, and the distribution of density is smoothed by a density smoothing means S6. Afterwards, when the multi-level image is inverted, the image is inverted again by a multi-level image reinverting means S7.  Thus, since the image having a density higher than a prescribed value is processed after being inverted, the quality of the image can be kept.
