Title: Character string extracting method
Inventor: MATSUMURA SUEKI
IPC: G06K9/20
Filed: 1995-06-26
Abstract: PURPOSE: To provide the character string extracting method which can stably extract a character string irrelevantly to unstable elements which are different, character by character, like the structure of strokes of a character. CONSTITUTION: A background part on a document inputted as image data is noticed and the image data are scanned with a circle 201 of specified size. Only when the circle does not contain none of the pixels constituting a character string, the center coordinate point of the circle is generated as a trace point 203. Trace points which are not in contact with the character string among trace points 203 that are thus generated, i.e., points encircled with only track points are regarded as points that do not contribute to character string extraction and deleted. Consequently, points encircling the character string are generated and an optional entry position and an optional tilt angle are precisely specified for the optional character string to stably perform character string extraction.

IPC: B21D19/08
Filed: 1997-06-02
Abstract: PROBLEM TO BE SOLVED: To respectively disperse a shearing force within the range of each side of a polygonal opening shape of a prepared hole, to respectively disperse sharp edges and burrs within the range of each side and to make them small, by forming the prepared hole of a burring member installed with the prepared hole for burring into almost polygonal opening shape. SOLUTION: A burring punch 3 installed coaxially with a center axis of a die 4 is moved downward vertically toward the center of a prepared hole 2 having an almost triangular opening shape while rotating from the upper side of a shear 1. A part corresponding to nearby the center of each bottom side of the almost triangular shape among the circumferential part of the prepared hole 2 is pushed down gradually along a slope of a conical projection 3b, it is spread gradually along the direction of rotation of the burring punch 3, receiving the shearing force along these directions and it is stretched. In this time, because all the face of the part to be stretched is always attached closely to the slope of the conical projection 3b, the shearing force is not concentrated locally.

IPC: G02B1/14
Filed: 1989-06-22
Abstract: PURPOSE:To provide a coating glass having a smooth and firmly bonded hard carbon film by increasing the number of nuclei in the formation of the hard carbon film. CONSTITUTION:Carbon of an evaporation source 12 is evaporated in vacuum with a laser light from a laser source 24 and ionized. The carbon ion is accelerated and, at the same time, made to collide with Ne ion emitted from a gas ion source 13. The ion excited to a high energy state collides with a surface of a glass 11 used as a material to be coated. The surface of the glass 11 is activated by the collision of the Ne ion particles to form a nucleation sites for forming precipitation nuclei of hard carbon. In the above procedure, a laser light from a laser oscillation source 14 is applied to the back face of the glass in such a manner as to be reflected from the front face of the glass. The process is effective in preventing the generation of fine powder caused by the reaction of carbon atoms, carbon ions, etc., before the carbon vapor reaches the surface of glass 11 and, accordingly, enables the formation of a hard carbon film having a large number of precipitation nuclei in the formation of the hard carbon film.
