Abstract: A satellite dish antenna assembly includes a dish surface, a convexly curved arc surface, a pair of corresponding protruding edges A, B disposed at the utmost front end of the two sides and serving as a base line AB, such that upper and lower ends of the arc surface are extended from the two protruding edges along the dish to a level position of the base line AB to form an upper and a lower pulling surface coupled to the two protruding edges respectively, and a flange is installed at the periphery of the dish surface and its front side is substantially level, so as to overcome the shortcomings of the prior art antenna dish that may be deformed or warped easily when pressed and improve the life of the antenna and the accuracy of receiving signals.

Abstract: A vacuum low-temperature distilled pure water dispenser includes a water-supply tank communicating with a reaction chamber via a water supply line, a pure water storage tank communicably located above the reaction chamber, an actuating pump communicably located below the reaction chamber, and a refrigerating system having pipe lines extended between the reaction chamber and the pure water storage tank. When the actuating pump is actuated, a vacuum is produced in the reaction chamber to suck water in the water-supply tank into the reaction chamber, at where the sucked water is heated and vaporized by heat provided by a compressor of the refrigerating system, so that impurities, organic and inorganic matters, bacteria, and viruses in the water are separated therefrom through vacuum low-temperature distillation. When the actuating pump keeps pumping, the distilled water is sent from the reaction chamber into the pure water storage tank.
