The invention provides a production method for stabilizers which produces with high productivity in a compact production line, without tempering. The production method for stabilizers of the invention includes: forming a steel bar material containing at least C: 0.15 wt % to 0.39 wt %, Mn, B and Fe into a product shape by bending; and quenching the bent steel bar material in a medium having a heat transfer coefficient higher than or close to that of water.

An exterior panel is formed of superplastic materials, including an exterior skin of titanium to accommodate high thermal stresses imposed on hypersonic transport vehicles during hypersonic flight. The exterior skin is fixed to an underlying reinforcing skeletal structure consisting of a superplastic formable reinforcement (SFR) layer, for example a titanium, zirconium, and molybdenum (TZM) alloy, which supports the exterior skin whenever the latter may be heated to temperatures exceeding 1200 degrees Fahrenheit. The exterior panel includes a separate interior skin configured for attachment to a frame member such as a rib, stringer, or spar of the hypersonic transport vehicle. A multicellular core is sandwiched between the exterior and interior skins to impart tensile and compressive strength to the exterior panel. In one disclosed method, the core is superplastic formed and diffusion bonded to the exterior and interior skins.

A stamped steel detectable warning tile and method of forming such includes preforming structures in the tile and subsequently coining the structures to form tactile portions to provide satisfactory end results. Further, the tactile portions can be formed in a staggered fashion along a press to distribute tonnage and extend the lifespan of the press, as well as control a curvature of the tile due to the press operations.

Provided is an electrode sheet rolling apparatus including: a process unit for performing a rolling or notching process of an electrode sheet, a rewinding unit for winding the electrode sheet finished with the process in the process unit, and a guide roll system which is disposed between the process unit and the rewinding unit and guides the electrode sheet from the process unit to the rewinding unit, wherein the guide roll system includes a plurality of rolls arranged in parallel with each other, and temperatures of the plurality of rolls are set sequentially high along a transfer direction of the electrode sheet.

The panel structure includes: a stiffened panel and a stiffening panel which is joined to the stiffened panel. The stiffening panel integrally has top end plate parts which are joined to a plate surface of the stiffened panel, a base part which is separated from the plate surface of the stiffened panel and faces the plate surface, and a plurality of pillar parts which connect the base part and the top end plate parts. One end part of each of the pillar parts is connected to the base part, another end part is connected to each of the top end plate parts, and a cross-sectional shape of each of the connecting parts a in direction from the one end part toward the other end part is bent or curved. Between the pillar parts neighboring each other, openings are formed.
