Abstract: A reinforcement, joined by welding to a vehicle structural member having a closed cross section, comprising a curved section at least in part of its length, a top wall having opposite edges, and a pair of lateral walls extending from the edges to form ridge lines, wherein the top wall and the lateral walls form a U-shaped cross section. The lateral wall includes a base surface and a plurality of welding projections at intervals along its length, each welding projection having a raised surface for welding. Each welding projection is raised from the base surface of the lateral wall toward the vehicle structural member. The lateral wall further includes a bead between the welding projections within a curved section to prevent or suppress wrinkles from forming during press forming. The bead is raised from the base surface of the lateral wall toward the vehicle structural member.

Abstract: In order to easily and accurately manufacture a micromachine comprising a member which is made of a single-crystalline material and having a complicated structure, an uppermost layer (1104) of a single-crystalline Si substrate (1102) whose (100) plane is upwardly directed is irradiated with Ne atom currents from a plurality of prescribed directions, so that the crystal orientation of the uppermost layer (1104) is converted to such orientation that the (111) plane is upwardly directed. A masking member (106) is employed as a shielding member to anisotropically etch the substrate (1102) from its bottom surface, thereby forming a V-shaped groove (1112). At this time, the uppermost layer (1104) serves as an etching stopper. Thus, it is possible to easily manufacture a micromachine having a single-crystalline diaphragm having a uniform thickness. A micromachine having a complicated member such as a diagram which is made of a single-crystalline material can be easily manufactured through no junction.
