Abstract: A method of fabricating a metal mask includes receiving a metal planar substrate and patterning the metal planar substrate. The metal planar substrate includes a first surface and a second surface opposite to the first surface. The patterning the metal planar substrate includes forming strip-shaped structures, forming through holes, and forming a blind hole in a direction from the first surface to the second surface. The through holes extend to the first surface and the second surface. The through holes and the strip-shaped structures are alternately arranged. The blind hole extends across the through holes.

Abstract: A discharger structure on earloop facemasks includes at least one opening hole on an earloop facemask covered by a cover. The cover is in a streamline shape and has a passage space for airflow. A check valve is disposed in the opening hole at an inner side of the cover, and the cover further has a discharging hole at an opposite side of the check valve, defining an area within the passage space between the check valve and the discharging hole for airflow. Thereby the check valve is closed by a diaphragm when air pressure within the facemask is negative, and the check valve is opened by the diaphragm when air pressure within the facemask is positive, so as to control airflow through the check valve.

Abstract: A blower includes a housing unit, a fan blade unit, a driving device, a start capacitor, a switch device, and a power source device. The power source device is connected electrically to the switch device. The housing unit includes a driver housing for receiving the driving device, and a fan housing for receiving the fan blade unit. The driver housing includes a mounting recess. The housing unit further includes a cover plate for covering removably the mounting recess. The start capacitor and the switch device are disposed removably within the mounting recess, and are connected electrically to the driving device at the mounting recess.

Abstract: A water activating apparatus includes (a) a plurality of floatable fibrous filter balls, an atomizer, a plurality of bio-chemical ceramic wave energy tubes, a receiving barrel, and a magnetizer, (b) a water softening device, (c) an ultraviolet sterilizing lamp, a porous bio-chemical ceramic wave energy plate, a plurality of magnetized bodies, an multi-layer stainless steel filter net, and a filter barrel, (d) a faucet, (e) a sprayer, (f) a sprayer switch mounted between the faucet and the sprayer, (g) a reverse washing switch, (h) a water flow monitor, (i) a gas/water mixer, a magnet-actuating reciprocating high pressure air pump, and a super-oxygen generating barrel, and (j) a transfer device. Thus, the water is activated efficiently, thereby enhancing the water quality contained in the receiving barrel.

Abstract: A wet process with no heating for continuous transfer pattern printing of a cellulose fabric web or its blends by using a corona-treated plastic film as a pattern carrier web and a dye admixed with a thickening agent containing water-soluble and alcohol-soluble hydroxypropyl cellulose or polyvinyl pyrrolidone as ink.
