Abstract: A hydrogen-oxygen separation energy-generating system includes a water replenishing chamber, reactors, a reaction body, a metal catalyst reactant and a gas collecting chamber. The system further includes a gas filtering chamber, a buffer chamber, a temporary storage chamber, settling tanks, a screw cleaner, and hardware therebetween, such as communication pipes and valves, to provide an environment-friendly hydrogen-mixed gas. The hydrogen-mixed gas is flammable, and has hydrogen content of 30% or above. Each reactor has a water admitting valve, a water draining valve, a vent valve, and connection valves. The reactors are connected by openable/closable connection valves through gas-delivering pipes such that the metal catalyst reactant in each reactor reacts with water independently, allowing the system to operate around the clock and every day and thereby be conducive to mass production.

Abstract: A dual-interface card reading device, having a main body and cover plate assembled to form an opening which accommodates insertion of a magnetic card or an IC card, one side of the opening defining a hollow slide groove to enable swiping of a magnetic card or an IC card. A magnetic head extends into the opening to read the magnetic card, and at one end of the hollow slide groove is an IC card contact interface for reading the IC card. A user can thus simultaneously swipe either type of card at an appropriate interface while achieving the effects of small size, low cost, and convenient operation.
