A method of generating a building assembly that includes spraying a coating material onto a plurality of pieces of substrate disposed on a first assembly face. The spraying includes spraying the coating material onto the plurality of pieces of substrate via a sprayer configured to apply the coating material to a target surface via a nozzle coupled with a mobile storage container storing the coating material, the coating material impregnating voids of the substrate. The method also includes allowing the coating material impregnating the voids to dry and harden and become rigid to generate the building assembly.

A surface acoustic wave module (SAW module) includes a piezoelectric element substrate including a piezoelectric body, an IDT disposed on a front surface of the piezoelectric element substrate and including a comb-like electrode pair, and a coating layer covering the piezoelectric element substrate and the IDT. The coating layer is disposed on the front surface of the piezoelectric element substrate, an end surface of the piezoelectric element substrate, and a corner portion between the front surface of the piezoelectric element substrate and the end surface of the piezoelectric element substrate.

A wear resistant mounting post for a distributor cap in a rotary bell cup atomizer. The mounting post includes a flange separating a thin barbed end from a larger diameter central portion. The flange fits into a countersunk depression in the distributor cap to provide a flange surface which is flush with the distributor cap surface. Paint flowing radially outward across the distributor cap follows the flange surface to the central portion of the post. This design prevents the paint from undercutting the surface of the distributor cap, and ensures that any abrasive wear of the post is limited to the larger diameter central portion.
