摘要： PROBLEM TO BE SOLVED: To provide a process for producing a porous metallic body which manufactures the porous metallic body by uniformly electroplating particularly to the ends thereof at the time of using a porous resin body as skeleton and subjecting the body to a conducting treatment, then to electroplating. SOLUTION: The porous resin body 1 passes between guide rolls 4 and power feed rolls 5 before the porous resin body enters an electroplating cell 3. During this time, the sheet ends 7 of the porous resin body 1 are detected by detecting means 6. When the positions of the detected end enter the electroplating cell 3, the operation to change one of the positions of shielding plates 8 mounted at the ends of the electroplating cell is executed by driving motors 9. When the signal of the next position enters, the shielding plates 8 are moved in accordance with the signal. The shielding plates 8 divided to three sheets are illustrated. The electroplating thicknesses of the end faces of the porous metallic body are controlled and the difference in the coating surface density in the central part of the sheet is eliminated.

摘要： PROBLEM TO BE SOLVED: To provide a good battery electrode base by improving a conductivity imparting process involved in the manufacture of a porous metal, and reducing the amount of carbon included in the porous metal finished. SOLUTION: This manufacturing method for a porous metal comprises the process of imparting conductivity to a porous resin and that of thermally removing electroplating and the resin. The process of imparting conductivity is characterized by the application of a viscous paint containing non-crystalline carbon particles serving as a conducting material. The conducting material may be roughly spherical carbon particles. The roughly spherical carbon particles should preferably be non-crystalline carbons.

摘要： PROBLEM TO BE SOLVED: To provide a good metal porous body with almost no difference in directional property by specifying the ratio of length and breadth of a pore of resin by applying permanent strain to foamed resin before plating when the metal porous body is manufactured by plating the foamed resin. SOLUTION: Before plating of foamed resin (foamed urethane or the like), conical rollers 3, 4 are pushed at the specified angle against an elastic foamed resin sheet 2 coiled around a roll 1, rotated in accordance with the running direction of the sheet 2 to spread the sheet 2 in the width direction by the difference in diameters of the rollers 3, 4. The angle, diameter ratio, pushing force against the sheet 2 of the rollers 3, 4 are adjusted based on the material, breadth of the sheet 2, and the ratio of length and breadth of the pore diameter of the sheet 2 is controlled to 1.2 or less by the remaining permanent strain. The directional property of a metal porous body is decreased so as to have almost the same tensile strength in any direction, and a storage battery with stable quality can be obtained.

摘要： PURPOSE:To produce a metallic porous material having high porosity, high strength and low electric resistance at a low cost by dispersing fine particles for reinforcing in a skeleton metal having three dimensional meshlike structure. CONSTITUTION:A coating film 7 of a coating material containing at least one kind of the fine particles of a material selected from the oxide, carbide or nitride of the elements of group II-VI in Period Table (Al2O3, WC, TiN or the like) is formed on the surface of a skeleton resin 6 of a three dimensional meshlike resin porous body. A metal plated layer 8 (one of Ni, Ni alloy, Cu, Cu alloy) to be a metallic skeleton is applied on the surface of the coating film 7. Next, the metallic porous material >80% in porosity, having communicated pores and composed of the three dimensional meshlike metallic porous body having the fine particles dispersed in the skeleton metal is formed by dispersing the fine particles in the coating film 7 in the metal plated layer 8 by heat- treating and removing the skeleton resin 6 and the coating material of the main component of the coating film. As a result, the metallic porous material having >=80% porosity and improved in strength is obtained without increasing electric resistance or cost.

摘要： PURPOSE:To allow the tip part of a torch to exactly follow up the center line of a butt weld zone and to obtain desired weld strength by picking up the images of the center line of the butt weld zone and the tip of the torch by a two-dimensional CCD camera. CONSTITUTION:A lens groups 51 of the two-dimensional CCD camera 5 attenuates arc light to about the extent to allow a two-dimensional image sensor 52 to detect the welding image and picks up the image of the weld line. The sensor 52 converts the weld image to the electric charge corresponding to the lightness of the weld line, resolves the charge in X-, Y-directions and transfers the same successively to an A/D conversion part 6. The A/D conversion part 6 converts the lightness values of the weld line picked up by the CCD camera 5 to the digital values of plural gradations and outputs the same to an image data memory 7. An arithmetic processor 8 measures the center line L of the butt weld zone and further controls the tip of the torch so as to follow up the center position of the butt weld zone. An output interface 9 aligns the tip of the torch and the center line of the butt part according to the tracking command signal from a control section.

摘要： PURPOSE:To prevent the blister and partial exfoliation of a clad material by controlling the surface of press-welding rolls to a specific temp. at the time of longitudinally press-welding a bar of a belt-like good electrical conductor metal narrower than the width of a belt-like base metal onto the base metal surface of an alloy material. CONSTITUTION:The belt-like base metal 1 having about 0.2-1.0mm thickness is let off from a bobbin 1 and the surface to be clad is polished by a wire brush 5, etc., by which the surface is cleaned up. The bar of the good electrical conductor metal sized about 0.005-0.1mm thickness and let off from the bobbin is superposed and press-welded to the base metal 1 near the inlet of work rolls 6 to form the clad material 9 which is then coiled. The upper and lower work rolls 6 and/or upper and lower back up rolls 7 are made hollow in this stage and water or warm water is passed in the rolls to control the surface temp. of the rolls to the temp. above the dew condensation point of the atmosphere around the rolls and below the dew condensation +30 deg.C. The intrusion of the condensed water into the space between the base metal 1 and the bar 2 is thereby prevented and the generation of the blister and partial exfoliation in the clad material 9 is prevented.

摘要： PURPOSE:To prevent the contact between a rolling roll and the surface of a clad strip and to prevent the flawing on the surface of the clad strip by friction or the sticking of metallic debris thereto by interposing a lubricative resin sheet between a cladding metal and the rolling roll. CONSTITUTION:A base metal strip 1 and the cladding metal 2 to be superposed on the surface thereof are rolled while the lubricative resin sheet 5 is passed between the metal 2 and the rolling roll 3 in the case of passing said strip and the cladding metal between the rolling rolls 3 and 3' and rolling and press- welding the strip and metal. The sheet 5 protects substantially the clad strip 4 and prevents the contact between the roll 3 and the surface of the strip 4 and therefore the surface of the strip 4 is entirely kept free from the flawing by friction and the sticking of the metallic debris. Since no lubricating oils are used, the defective adhesion of the metal 2 arising from the intrusion of the lubricating oil into the joint boundary is eliminated. The clad strip 4 having high quality is thus obtd.

摘要： PURPOSE:To improve adhesion of low melting-point glass and a lead frame, by keeping the value of the surface roughness of the uncoated surface of an Al layer specified one or less. CONSTITUTION:A lead frame 11, which is formed by blanking an Fe-Ni alloy material, and package ceramics 13 an 13' are sealed with sealing low melting- point glass pieces 14 and 14'. An IC chip 15 is connected to an Al layer 12 on the upper surface of the lead frame 11 comprising an Fe-Ni alloy substrate with wire bonding 16. One surface of the lead part of the frame 11 is coated with the stripe shaped Al layer 12. The surface roughness is treated as 0.01mum or more and 1mum or less. Alminum oxide Al2O3 is diffused into the low melting- point glass adequately on the Al coated surface, and adhesion with glass is reinforced. Meanwhile, the surface roughness of a side 17 of the lead frame 11, which is not coated with Al, is kept at 0.8mum or more and 1.2mum or less.
