Title: Production of optically inactive film
Inventor: ICHIKAWA RINJIROU
IPC: B29C55/00
Filed: 1983-05-17
Abstract: PURPOSE:To obtain an optically inactive film which is smooth and has good flatness by interposing a thermoplastic material in at least a part between a holding part and the film and holding said part. CONSTITUTION:A self-adhesive tape 5 is interposed as a thermoplastic material in the four sides of an untreated film 1 and the four sides are fixed to a holding part 2. Both ends of the long-sized film 1 are continuously fixed by means of a tape 5 and pin tenters 3. The area of only the tape 5 is required to be 0.1-20%, more preferably 1-10% with respect to the entire area of the untreated film in order to absorb fully the shrinkage stress and other stresses of the untreated film in the part of the tape 5 which is the thermoplastic material. If the area is <0.1%, the shrinkage stress of the treated film cannot be thoroughly absorbed and if the area exceeds 20%, the treated film sags and has decreased flatness.

IPC: G06K9/20
Filed: 1989-04-05
Abstract: PURPOSE:To recognize a frame in a table regardless of the presence/absence of ruled lines on the both sides of the table to be an object, and to segment a picture in the frame by segmenting the picture in each frame in the table of an inputted binary picture, and when a character is recognized, generating the virtual ruled line to the table having no ruled lines on the both sides. CONSTITUTION:For the table area image of a table area picture memory 22, an x-directional line segment extracting part 13 extracts the line segment in the (x) direction, holds it in an x-directional line segment coordinate memory 23, a y-directional line segment extracting part 14 extracts the line segment in the (y) direction, and holds it in a y-directional line segment coordinate memory 24. Next with the use of the x- and y-directional line segment coordinate memories 23 and 24, whether or not the ruled lines exist on the both sides of the table to be the object is decided by a both-side ruled line presence deciding part 15, and the virtual ruled lines are generated for the table without the ruled lines on the both sides by a virtual ruled line generating part 16. Thus the picture in the frame of the table, where the ruled lines do not exist on the both sides and which often appears in a document picture can be segmented, and a processing such as the character recognition can be executed.

Filed: 1980-06-27
Abstract: PURPOSE: To improve shape of bead by giving an angle to the second alloy side against a weld groove face and irradiating electron beam to the perpendicular direction inside of thickness of a weld groove face and thereby reducing generation of  metallic vapor.  
     CONSTITUTION: An electron beam 4 is inclined by an angle θ that minimizes the penetration of a bimetal alloy 1 to the side of a bimetal alloy 2 that is opposite to the bimetal alloy 1 composed mainly of Mn, and the beam is irradiated toward a point D which is the necessary minimum penetration depth on a perpendicular line of a weld groove face 5. By this way, generation of metallic vapor can be minimized to reduce penetration of the bimetal alloy 1, and electron beam welding that gives a stable penetration depth can be effected. Further, good welding can be effected by oscillating the electron beam according to the gap of the groove or bending of the weld line.
