Title: Arc sensor welding method for forming weld bead shape asymmetrically
Inventor: TOYODA KENICHI
IPC: B23K9/127
Filed: 1987-06-08
Abstract: PURPOSE:To facilitate forming asymmetric beads by weaving a torch asymmetrically with respect to a weld line and adjusting the difference between arc current integrated values of each half of the right and left of the weaving width to perform the welding. CONSTITUTION:The torch 4 is offset by the distance D on one work 7 in a groove 7 and arranged thereon. At this time, the objective position P of the torch 4 is deviated from the weld line and the torch 4 is made to perform the weaving between the left end L and right end R with a weaving plane angle beta of 90 deg.. In this case, although an arc current draws a waveform 8 by the weaving, the difference 9 between the current integrated values of each half of the right and left of the weaving width W is inputted to a torch control program as an adjustment value in advance. By this method, since a travel command of the torch 4 is detected only by the deviation from the offset position P, the asymmetric weld beads are easily formed.

Title: Manufacture of solar heat absorber
Inventor: YAMAKAWA SEISHIROU
IPC: F24J2/48
Filed: 1981-09-07
Abstract: PURPOSE:To improve the absorption factor for solar heat and the heat resisting property of the absorber by a method wherein copper electroless plating is applied over the surface of a substrate, at least the surface of which is nickel, and said plated layer is oxidatively treated in order to obtain a selective absorber film of cupric oxide. CONSTITUTION:The solar heat absorber uses a substrate, which is made of solid nickel or on the surface of which a nickel film is applied, as a metal basis. Said nickel substrate is copper electroless plated and, after that, oxidatively treated with chemical conversion treatment solution in order to convert the copper plated layer over the surface of the substrate into the selective absorber film consisting of cupric oxide. Said copper plating is performed with the contact of the surface of the substrate with acid solution containing copper ions by immersing the nickel substrate into the acid solution containing copper ions. In such a manner as described above, the solar heat absorber with enlarged absorption factor and excellent heat resisting propety can easily be obtained.
