摘要： This arc spot welding method for dissimilar materials joins a steel upper plate and a non-ferrous metal lower plate. The upper plate has a flat plate-like base part and an upright wall part erected on the base part. The base part has a through-hole. The arc spot welding method for dissimilar materials includes superposing the base part on the lower plate so that the lower plate faces the base part via the through-hole; and arc-welding the base part and the lower plate by filling the through-hole with a molten weld metal at a position, which is a target position, offset in the direction opposite the upright wall part from the center of the through-hole.

摘要： A liquid separation constituent is used by covering a first element portion having a fiber layer for separating liquid from gas discharged from a compressor, and includes a second element portion, a holding portion, and a non-element portion. The second element portion is a tubular portion having a fiber layer that is disposed on the outer side in the radial direction so as to surround the first element portion when the second element portion covers the first element portion and further separates liquid from gas separated by the first element portion. The holding portion is a portion that holds the second element portion such that a gap is formed between the first element portion and the second element portion in the radial direction. The non-element portion is a portion configured to suppress liquid seeping out from a lower portion of the first element portion from scattering to the second element portion.

摘要： A steel sheet may be used for hot-dip galvanizing capable of manufacturing hot-dip galvannealed steel sheet(s) with a high Si content and in which alloying unevenness is suppressed. Such a steel sheet for hot-dip galvanizing may include an internal oxide layer containing an oxide of Si between a surface layer of the steel sheet and a steel sheet base portion. The Si content in a chemical composition of the steel sheet may be 1.0 mass % or more. A solid solution Si amount from a surface of the steel sheet to a depth of 1 μm measured at all four positions including positions of 10 mm, 30 mm, and 50 mm from an edge in a coil width direction and a position of a center in the coil width direction at a rear end in a rolling direction of the steel sheet for hot-dip galvanizing may be 1.4 wt. % or less.

摘要： A door beam includes an outer flange, an inner flange, and a pair of webs connecting the outer flange and the inner flange. The outer flange, the inner flange, and the pair of webs define a closed cross-sectional portion. The outer flange includes an outer central portion constituting the closed cross-sectional portion, and outer protruding portions protruding outward from the closed cross-sectional portion. The inner flange is formed with an attachment press working portion having been subjected to press working so as to serve as an attachment portion with respect to the inner panel at both end portions in the longitudinal direction. The outer protruding portion is formed with a mastic press working portion having been subjected to press working so as to serve as an attachment portion with respect to the outer panel.
