Abstract: A maglev generator assembly has a main axle extending through a casing. The main axle has its two ends magnetically levitated by maglev supports, and has its lateral side magnetically levitated by maglev bearings. A generator is configured on the main axle, which includes at least a rotating disc as rotor, with multiple inductive magnets circularly arranged around the rotating disc, and a number of coils fixed around the main axle as stator. A top end of the main axle is coupled to a transmission mechanism, which in turn is coupled to a fan unit or a motor as power source. The fan unit or motor drives the main axle, as well as the rotating disc to spin, and electrical current is induced as the inductive magnets rotates relative to the coils. The main axle is fully magnetically levitated and its rotation undergoes minimum friction to achieve high efficiency.

Abstract: A low-energy-consumption and high-efficiency circulating electric motor that a fan and a circular cylinder-body are disposed on a rotating-shaft and a permanent magnet is disposed on at least one blade of the fan, and at least a permanent magnet is disposed in a frame; wherein the outer diameter surface of the circular cylinder-body is set with a continuous circumferential conductive portion, and a plurality of axial conductive portions are lined in interval and connected with the circumferential conductive portion; wherein a DC generator is connected with the rotating-shaft and a storage battery is electrically connected with a control unit, the DC generator, the circumferential conductive portion, and the DC electromagnet; at the same time, the DC electromagnet intermittently generates a magnetic force by orderly contacting and not contacting the axial conductive portions; and the fan is continuously rotated by the intermittent magnetic force interacting with the permanent magnet.

Abstract: A waterproof breathing PU film preparation method include the steps of (a) processing polyurethane polymers into a polyurethane colloid, (b) mixing the polyurethane colloid with a cationic water repellent and a cationic bridging agent at a ratio that the cationic water repellent and the cationic bridging agent take about 1%˜10% and the polyurethane colloid takes about 900%˜99% to provide a polyurethane mixture, and (c) using the polyurethane mixture to make a waterproof breathing PU film having a thickness ?0.01 mm.

Abstract: A method of preparing a waterproof paper box by: providing a silicon rubber coating material having a viscosity about 15000 to 30000 cps and applying the silicon rubber coating material to the surface of a paper sheet material, and then applying a pressure about 2˜3 kg/cm2 to the silicon rubber coating material and the paper sheet material to cause permeation of the silicon rubber coating material into internal fibers of the paper sheet material so that a silicon rubber waterproof film is formed on the surface of the paper sheet material, and then processing the silicon rubber coating material-coated paper sheet material thus obtained into a paper box that has the silicon rubber waterproof film located on the inside.
