Title: Welding method of cylindrical member, and cylindrical body
Inventor: IWAI KOJI
IPC: B23K26/21
Filed: 1997-11-18
Abstract: PROBLEM TO BE SOLVED: To provide a welding method of aluminum difficult to generate cracks by providing a space slightly closer to an inner circumferential surface than to an outer circumferential surface of a weld part of a first member and a second member when the second cylindrical or disk-like member of the outside diameter approximately same as that of the first member to an end part of the first cylindrical member. SOLUTION: A converging lens to irradiate the YAG laser beam on a weld part 24 is arranged in the vicinity of the weld part 24 of a work 10. The laser beam is irradiated toward the weld part 24 from the converging lens to heat and melt a part in the vicinity of the weld part 24 between a cylindrical member 12 and a flange member 14 so as to be welded. A space 36 is formed slightly closer to an inner circumferential side than an outer surface of the weld part 24 between the flange member 14 and the cylindrical member 12. Because air has relatively large heat insulation effect, air in the space 36 prevents the heat of the weld part 24 from transferring to a center part of the work 10, and the cooling speed of the weld part 24 is reduced. When the cooling speed of the weld part 24 is reduced, no excessive stresses are generated, and occurrence of cracks can be prevented.

Title: Picture processor
Inventor: YAMAKAWA SHINJI
IPC: G06T3/00
Filed: 1995-11-10
Abstract: PROBLEM TO BE SOLVED: To obtain a picture processor having high resolution. SOLUTION: Each of plural pattern matching parts 43 to 45 extracts black edges around a white area with respect to the relation between the white area of a line drawing and black picture elements. In this case, a white area pattern is a white area signal and a black pattern is demoted as 'H' for one that the number of black picture elements or the number of edges is larger than a threshold. In the pattern matching parts 43 to 45, picture data are classified in accordance with the characteristics of pictures and extracted. For instance, a horizontal component, vertical component, an oblique component, a thin line such as a ruled line and a character, and an edge on a white area, etc., are extracted. The black pattern is not extracted simply based on a simple black picture element. Because blur generated at the time of reading out an original is corrected by the number of edges.  Binarized data are corrected based upon Laplacian, the white area is referred to, and a character in a white ground can effectively be extracted.

The steel slab is rolled at 600-750 deg.C, heated to a temp. in the range between the Ar3 transformation temp. and 1000 deg.C, and hot-rolled at a temp. not lower than the Ar3 transformation point so that total draft in the three passes in the latter stage becomes >=70%, by which the average γ-value is regulated to a value as high as >=1.0. Subsequently, the resultant hot rolled plate is cooled rapidly down to 250-450 deg.C at >=20 deg.C/sec cooling rate and held at this temp. for at least 60min, by which solid-solution carbon is precipitated in the form of Fe3 C.  By this method, the non-aging hot rolled steel plate, having >=20MPa aging index and >=1.0 average γ-value and excellent in deep drawability, can be inexpensively produced.
