Title: Laser beam machining method and device therefor
Inventor: KANEOKA MASARU
IPC: B23K26/064
Filed: 1996-01-30
Abstract: PROBLEM TO BE SOLVED: To enable excellent cutting by moving a machining head simultaneously in the directions parallel and vertical to the surface of a work while performing laser beam irradiation and assist gas injection thereby bringing a converging point close to a piercing point. SOLUTION: After a focal position is set at P(a, b, c), and the surface of a work W is heated by the irradiation of a laser beam in a wide area, the machining head 3 is moved simultaneously in the lowering and horizontal directions, reaching a position O(O, O, O). The scattering molten metal S generated in the advancing process of piercing is scattered and deposited in the direction reverse to the moving X direction of the machining head 3; therefore, there is no risk of causing defects. Expansion of a piercing hole is prevented at the time of piercing, by stopping a gas injection or injecting a gas like air/ argon, from the outer nozzle in a dual nozzle system for the purpose of improving cutting quality. Thus, cutting is excellently performed after piercing, reducing generation of defects.

Then, the other bipolar heat transfer element 2 is cooled by the supply of the heat. After the keeping of warmness is completed, when the current direction changing-over switch 4 is set so that the current can flow in the reverse direction, the heating and cooling directions are made reverse and the bipolar heat transfer element 2 in the side of the cooking plate 1 is speedily cooled. Then, the warmness keeping heat of the cooking plate 1 is speedily lost and the cooking plate 1 is cooled as well.

Title: Multicellular glass form and its production and production unit therefor
Inventor: NAKAMURA NOBUO

Filed: 1992-01-31
Abstract: PURPOSE:To obtain a multicellular glass form bearing the profound, and elegant appearance inherent in glass by monolithically laminating a multicellular glass layer with a dense glass layer followed by dividing the multicellular glass layer and providing the stripes of dense glass to enable the end faces to be reinforced. CONSTITUTION:A multicellular glass layer 1 is monolithically laminated with a dense glass layer 2 and then divided to provide stripes 3, 4 of dense glass (where, the stripes 4 are laid at the end faces), thus obtaining the objective multicellular glass form 5. A design is taken, as the case may be, such that each width of these stripes 3, 4 be set at 5-10mm or so and the distances between them several tenths to 100cm or so. If these distances are far greater than 100cm, the reinforcement gets meaningless; on the other hand, in case the distances are set at ca. 10cm, the lightweight characteristics and thermal insulation, advantages of the final multicellular glass are impaired. The multicellular glass layer can be obtained, for example, by heat-treating, softening and expanding a raw material chiefly comprising glass powder and a foaming agent; or by blending such raw material with vitreous granules expanded in advance, i.e., multicellular vitreous granules followed by carrying out heat treatment.

Abstract: PURPOSE:To eliminate the need for setting up a specific background and to extract and input only the image of an object with a specific distance by detecting a distance from a photographing position from relational positions between objects generating a difference and extracting only the image of the object arranged with a specific distance. CONSTITUTION:A visual difference detecting part 5 compares two positions in the frame of a difference area from two difference matrixes sent from difference detecting parts 41, 42 by a prescribed procedure and sends the compared result to a mask forming part 6 together with the difference matrixes. The mask forming part 6 refers a compared result list, checks whether a visual difference between respective difference areas is included in a threshold range or not, and when the difference is included in the range, rewrites the value of elements in the difference matrixes into '2' and sends the elements of '2' to extracting parts 71, 72. The extracting parts 71, 72 form two kinds of video signal based upon the frame of the input image and obtains an image by substituting a dummy signal value for the signal value corresponding to the picture element of '0' and '1' from one video signal. From the other video signal, a video signal obtained by substituting a dummy signal value for the signal value corresponding to the picture elements of '0' and '2' is outputted.
