The etching agent is an aqueous solution including at least one acid selected from the group consisting of inorganic acids other than nitric acid, and organic acids; and an organic nitrogen compound having a molecular structure containing N—OH or N—O.sup.−. The acid concentration of the etching agent is 0.05 to 3% by weight, and the organic nitrogen compound concentration of the etching agent is 0.005 to 5% by weight. By bringing the etching agent into contact with a surface of a magnesium component, fine irregularities can be formed on the surface of the magnesium component even when etching depth is large.

According to one embodiment, a mold includes a substrate clamping surface, a cavity, a suction part, a vent, an intermediate cavity, and an opening/closing part. The substrate clamping surface contacts a surface of a processing substrate. The cavity is recessed from the substrate clamping surface. The suction part is recessed from the substrate clamping surface. The vent is provided on a path between the cavity and the suction part, communicates with the cavity, is recessed from the substrate clamping surface to a vent depth. The intermediate cavity is provided between the vent and the suction part on the path, communicates with the vent, and is recessed from the substrate clamping surface to an intermediate cavity depth deeper than the vent depth. The opening/closing part opens and closes the path and is provided between the intermediate cavity and the suction part on the path.

A vertical axis laundry treating appliance including a chassis defining a chassis interior, a tub disposed within the chassis interior and defining a tub interior, and a perforated wash basket disposed for rotation within the tub interior, wherein the tub includes a lower tub portion, an upper tub portion, and a flexible intermediate portion.

A process for resin transfer molding (RTM) with staggered injection of a resin is provided that injects resin into a plurality of injection ports of a mold. The temperature and pressure applied to the mold are controlled during injection to limit promote rapid filling of the mold cavity. The injection ports are activated for injecting the resin in any order of individually, in groups, or pairings. Fibers are readily added to the mold separately or within the resin. Cycle times of from 1 to 5 minutes are provided for the process.
