In the method, at first, a mixing operation is performed to mix a plurality of metal gases. The metal gases consist of silver, magnesium, and aluminum, or consist of silver, copper, and aluminum, or consist of copper, Nickel, and aluminum. The metal gases have two or more atom sizes. Thereafter, a depositing operation is performed to deposit an amorphous metal film on the substrate by using the mixed metal gases. The atoms of the amorphous metal film are arranged in a short-range order. Then an annealing treatment is performed to anneal the amorphous metal film to form a meta-stable metal film having averagely distributed grains to be used as the protection film.

Abstract: A transformer for resonant inverter, which utilizes magnetic substances infilled between a primary coil and a secondary coil to compel part of the magnetic lines of force of the primary coil not to cross-link with the secondary coil, which thereby achieves regulating leakage inductance. Furthermore, need to renew an existing iron core and bobbin is eliminated, and surmounts the difficult problem of controlling leakage inductance in original configurational designs, thereby decreasing man-hours, enhancing efficiency, and saving on costs.

Abstract: The object of the present invention is a multi-functional electric generator comprising, an engine, a generator, a voltage-stabilizer control circuit, a gas storage gauge and a lighter. A manual electrical rod can be assembled to a side of the engine allowing the generator to be manually activated, or through the motor assembled inside the generator. The gas storage gauge assembled on a side of the engine can be connected with a conventional lighter through the lighter opening, allowing reception of the Butane gas from the lighter. Positive and negative poles are formed on a power output end connected to the voltage-stabilizer.
