IPC: G06K9/34
Filed: 1986-09-08
Abstract: PURPOSE:To automatically separate and extract a contact character having a high recognition factor by producing image data suited to recognition of characters after production of plural character candidates and comparing the character recognition results with each other. CONSTITUTION:A character component element detecting part 1 adds a segment to be connected from a contact point on line thinning data to detect the character component element and separates this element from a line pattern with high efficiency. Each detected character component element is checked through a character candidate producing part 2 for decision whether each element can form a single character or not. Then the character component elements which are enable to form a single character respectively are combined with other elements. Thus plural character candidates are produced. These character candidates are turned into the character image data suited to recognition of characters via the line thinning data by a character image data generating part 3. A character recognizing part 4 recognizes characters for plural character image data and a recognition result evaluating part 5 compares the recognized results with each other. Thus characters are finally decided.

IPC: B24D3/00
Filed: 1999-07-26
Abstract: PROBLEM TO BE SOLVED: To suppress the friction heat during the grinding, to improve the strength and hardness of a abrasive grain layer, and to prevent the loss in shape. SOLUTION: In this grinding wheel, superfine abrasive grains 13 are diffused in a binder phase 12 of a phenol resin. Fillers 14 containing both solid lubricants of CaF2 15 and ZnO 16 by 3-50 vol.% of the resin binder phase are diffused. ZnO 16 is contained by 10-40 vol.% of the total amount of the tillers while 15 vol.% of CaF2. When ZnO is contained less than 10 vol.%, the strength and hardness of the abrasive grain layer are small, the shape is lost, and the suppressive effect cannot be obtained. When ZnO is contained more than 40 vol.%, the strength and hardness are too large, the grinding resistance is increased, and the friction heat in the abrasive grain layer is increased. ZnO 16 is diffused in the resin binder phase 12 in a condition of the secondary particles in which multi-crystal primary particles are aggregated.

Filed: 1988-08-26
Abstract: PURPOSE:To obtain stable output image density without reference to an environmental change by measuring the insulation resistance of the insulating layer of a toner carrier by a resistance measuring means. CONSTITUTION:The resistance measuring means 15 which measures the insulation resistance of the insulating layer 13 is connected to part of the toner carrier 11 consisting of a conductive base 12 and the insulating layer 13.
