摘要: An improved glow discharge atomic emission spectroscopy method and apparatus is offered in which the introduction of a rare gas into a glow discharge tube is temporarily cut off and after the inside of the glow discharge tube is maintained at a higher degree of vacuum, a preliminary discharge is executed to remove adsorbed or extraneous substances on the specimen surface, and then the analysis of the specimen surface is performed. The method and the apparatus described in the above are suitable for quick and simple analysis of the uppermost surface layer of a solid specimen in the direction of depth.

摘要: Disclosed is a multi-point welding method capable of certainly welding an object having a number of points to be welded for a short time. First, an approximately cylindrical base body is formed by alternately laminating a flat sheet and a corrugated sheet and then winding them in a spiral shape. In this case, there exist a number of contact points of the flat sheet to the corrugated sheet, that is, points to be welded. Next, there is provided an electrode apart from one end surface of the base body by a specified interval and facing to the end surface. After that, by intermittently applying a current across the electrode and the one end surface of the base body thereby intermittently generating electric discharges between the electrode and the one end surface of the base body, to thus fuse and weld the points to be welded of the flat sheet to the corrugated sheet. With this arrangement, it is possible to certainly weld multi-points to be welded for a short time by only intermittently applying electric discharges.

摘要: A metal catalyst carrier for exhaust gas purification, comprising: a metal honeycomb column composed of flat and wavy metal sheets laminated, wound together, and bonded to each other to provide numerous exhaust gas flow paths along the column axis, the honeycomb column having a quasi-elliptical cross section defined by a pair of mutually facing linear portions and a pair of mutually facing curved portions in a plane perpendicular to the column axis, the flat and wavy sheets being bonded in a greater bond rate in the major axial end portions than in the other portion of the quasi-ellipse, the bond rate being defined as a quotient obtained by dividing a bonded length by a total length of lines on which the laminated and wound flat and wavy sheets are in contact with each other; and a columnar metal case fittingly enclosing the honeycomb column and bonded to the honeycomb column only in the portions corresponding to the curved portions of the quasi-elliptical cross section.
