Abstract: A metal carrier includes a core (3) having a thinned film containing a metal catalyst. The core includes a first metal sheet (1) corrugated and having a crest with a first radius (R). The core includes a second metal sheet (2) flattened or corrugated smaller in corrugation height than the first metal sheet, The first and second metal sheets are stacked on each other to be wound up. The crest and second metal sheet are joined to each other, having a joint therebetween. A fillet of the catalyst is formed between the joint, the first metal sheet, and the second metal sheet, having an arced surface of a second radius (r) extending between the first and second metal sheets. The first radius is set substantially equal to the second radius.

Abstract: A method of installing a seismic damping wall where the seismic damping wall is attached to the upper floor beam prior to installing the upper floor beam. A hanging plate is placed in the chamber defined by a standing structure plate. The hanging plate is temporarily attached to the standing structure plate. The top edge of the hanging plate is affixed to a horizontal structural beam that upon installation in the building will be an upper floor structural beam. The combined unit, comprising the horizontal structural beam, the hanging plate and the standing plate structure, is placed in position and the horizontal structural beam on the upper floor is installed in the building structure. The chamber is filled with a viscous liquid. The hanging plate and the standing plate structure which were temporarily fastened together are separated from each other. The standing plate structure is lowered down toward the horizontal structural beam on the lower floor.
