Title: Abrasive tape
Inventor: YAMAGUCHI NOBUTAKA
IPC: B24D11/00
Filed: 1985-10-18
Abstract: PURPOSE:To bring an abrasive tape into full sliding smoothness under any circumstances in abrading a magnetic head for improving the running stability thereof so as to abrade the same uniformly by containing a lubricant in a covering layer. CONSTITUTION:A lubricant made of fatty acid, fatty acid, fatty acid ester, silicon oil and interfacial active agent is kneaded with an abradant and a binder. Then, the so-kneaded material (covering layer) 4 is applied to a non-magnetic supporting member 1. In this case, fatty acid acts to soak out gradually from the inside of the covering layer 4 to the surface thereof owing to its strong polarity; fatty acid ester acts to soak out immediately to a surface 2 due to the lack of polarity; silicon oil serves effectively as the lubricant with small quantity regardless of the quality of material on which an abrasive tape slides, and interfacial active agent serves properly as the lubricant without loosing the effect under heated and pressured conditions.

Title: Coloring material for display element, display element using the same and color filter
Inventor: IWANAGA HIRONORI
IPC: G02B5/22
Filed: 1995-09-11
Abstract: PROBLEM TO BE SOLVED: To obtain a coloring material which realizes a high precision color display without decreasing light resistance by mixing two kinds of polymer fine particles containing dye molecules of compds. having different base skeletons from each other. SOLUTION: Each polymer fine particle 1 contains only dye molecules 2 or 3 of compds. having almost the same base skeletons. For example, wither anthraquinone dye molecules 2 or azo dye molecules 3 are capsuled in the polymer fine particle. Then these two kinds of polymer fine particles 1 are mixed. For example, the base skeleton of 1-aminoanthraquinone is almost the same as the base skeleton of 1,4-bis(phenylamino)anthraquinone, while the base skeleton of 1-aminoanthraquinone is different from the base skeleton of 4- methyl-7-diethylaminocumarine. It is preferable that the polymer fine particles 1 are liquid crystal microcapsules 4 prepared by sealing only dye molecules 2 or 3 in a liquid crystal material to make microcapsules.

Title: Device and method for extracting object and medium recording object extraction program and object detection program
Inventor: MATSUMOTO YUKINORI
IPC: G06T7/00
Filed: 1997-08-28
Abstract: PROBLEM TO BE SOLVED: To extract even the part of an object in the same color as the background as an object part. SOLUTION: An area dividing part 9 divides an object image into plural areas. A differential processing part 11 finds the difference of the object image and background image for the unit of an area. An average value deriving part 13 derives the average value of the absolute value of the difference for the unit of an area. A threshold value processing part 15 detects the area, where the average value of the absolute difference value is higher than a threshold value, as the object part. An object part extracting part 16 extracts the object part detected by the threshold value processing part 15 from the object image A. Even when the part in the same color as the back ground exists in the object at a pixel level, on the condition that a color different from the background at an area level exists, such a part can be extracted as the object part.
