IPC: B23K31/00
Filed: 1988-12-19
Abstract: PURPOSE:To efficiently obtain the stainless steel for far IR radiators by forming a stainless steel strip subjected to a dull skin pass treatment into a welded stainless steel pipe and forming this steel pipe as the steel pipe having specific outer peripheral surface roughness in a sizing stage for specific surface roughness, then forming an oxide film thereon in a high-temp. oxidation atmosphere. CONSTITUTION:The dull skin pass-treated stainless steel strip S is passed through a roll forming stage 1, a fin pass forming stage 2 for finish forming, a welding stage 3 for both edges of the seam, and a cutting stage 4 for the beads on the inside and outside surfaces to obtain the welded stainless steel pipe P1. Further, the steel pipe is passed through a post annealing stage 5 and a cooling stage 6, then through the sizing stage 7 having 2 to 30mu roll surface roughness, a cutting stage 8, and a leveling stage 9, by which the leveled stainless steel pipe P1 is obtd. The stainless steel pipe is then passed successively in a continuous heating furnace 10 to execute heating in the oxidation atmosphere by which the stainless steel pipe for far IR radiators having 2 to 30mu outer peripheral surface roughness and the oxide film (a) is produced.

Title: Method for correcting dummy image in digital image
Inventor: VELDE KOEN VAN DE
IPC: H04N1/40
Filed: 1999-11-10
Abstract: PROBLEM TO BE SOLVED: To obtain a method for correcting a pseudo-image generated as a result of the nonlinear processing of a component (coefficient) in multi-scale expression by equalizing the direction of a gradient image to the direction of a gradient image of multi-scale gradient expression of a source image, pixel by pixel, and generating corrected gradient expression. SOLUTION: The preudo-image in the processed digital image represented by the multi-scale gradient expression including a gradient image of multi- resolution level obtained by nonlinearly processing the multi-scale gradient expression of the source image and the remaining image is corrected. The gradient image is corrected to equalize the direction, pixel by pixel, to create corrected image expression. Then reverse multi-scale gradient conversion for giving multi-gradient expression at the application to the source image is performed to restructure a final output from the corrected gradient expression. This is therefore usable to correct the pseudo-image generated as a result of the nonlinear processing of the coefficient of the multi-scale gradient expression.

Title: Sentence editor
Inventor: YOSHIDA HIROICHI
IPC: G06F17/21
Filed: 1992-11-30
Abstract: PURPOSE:To enable enlarged display while eliminating necessity for designating an area again by providing a start pointer instructing means for input and conversion to execute processing similar to area designation at the time of enlargement processing and an end pointer instructing means for input and conversion. CONSTITUTION:When it is desired to enlarge an inputted character, for example, an area designation part 7 recognizes and designates the area to execute the enlargement processing by designating the head and final characters of a character string with cursors. A start pointer instruction part 8 for input and conversion copies the respective points to the respective start and end pointers of the area designation part 7 together with an end pointer instruction part 9 for input and conversion. When an inverted display part or an under line display part just after the input or conversion exists on a screen, the head and final characters of the displayed character string are copied to the respective start and end pointers of the conventional area designation part. Therefore, the instruction is enabled without issuing the instruction of area designation again.

Title: Manufacture of eyeless needle for operation
Inventor: MATSUTANI KANJI
IPC: B23K26/21
Filed: 1987-12-21
Abstract: PURPOSE:To prevent the generation of a crater by the generation of a spark by welding with the beam projection by superposing the initial welding part of the needle main body welded by at least bean projection and a pipe. CONSTITUTION:An eyeless needle is manufactured by integrally joining a needle main body 1 and pipe 2 linearly by projecting the laser light 6 of small power to these weld zone (a) from the outer peripheral side thereof with rotating them by synchronizing with chuck shafts 3a, 3b. The difficulty of the workability by piercing and the generation of a defective part can be prevented. Moreover smooth welding is ensured by a 2nd beam thermal spray on the welding turbulence caused at the initial welding part and the part of incomplete welding with a narrow welding width because the initial weld zone (a) is welded with the beam thermal spray by superposing it. The generation of a crater due to the spark generation can be prevented because of no need for making the projection power of the beam stronger.
