Abstract: The present invention provides a silver alloy material and a method for manufacturing the silver alloy material, the silver alloy material comprising essentially by weight of about 65% to 95% Ag, about 5% to 35% In. The silver alloy material has a solid-liquid coexistence zone. The steps for manufacturing the silver alloy material include mixing, heating in vacuum status, cooling and annealing. The characters of the silver alloy are low yield tensile strength (58 Mpa), high ultimate tensile strength (300 MPa) and high elongation (60%) and anti-tarnishing property. The silver alloy material could be used for optics reflector mirror, silver ornament, brazing materials and very fine silver alloy wire for semiconductor bounding application.

Abstract: A disposable sanitary spittoon including a spittoon container of plastic or paper, a cover associated with the container and a molded absorption block of high molecular hydrophilic polymer within the container. The block is formed with a through hole for receiving a tube, a recess at the bottom thereof, and a concave surface. The tube is made of plastic or paper and is provided with cilia on its interior surface. The lengths of the cilia increase with respect to the downward direction of the tube.
