Abstract: A tube flanging method includes the steps of: disposing a tube such that an edge thereof is exposed to the outside of a forming mold while the tube is inserted into the forming mold; applying an external force to the exposed edge of the tube to expand the exposed edge of the tube; applying an external force to the expanded edge to bend the expanded edge toward an outer surface of the forming mold; and applying an external force to the bent edge to form a flange, the flange having a linearly integrated cross section and being perpendicular to the longitudinal direction of the tube. With this configuration, it is possible to bend the tube to form the flange at a uniform thickness.

Abstract: Disclosed herein is a dishwasher using oscillatory flow generated from thermoacoustic effect. The dishwasher is configured such that thermoacoustic waves having high amplitude are generated from solar energy rather than electric energy, wherein the thermoacoustic waves make oscillating waves be directly transmitted to an air column and a water column formed in a closed end of a dishwashing pipeline. In this way, high-quality energy can be directly applied to washing water, whereby energy loss can be minimized, and the washing efficiency can be markedly increased.

Abstract: Disclosed herein is a high-efficiency acoustic wave generator using a pulsed thermal radiation beam. The generator is configured such that when a pulse beam formed by a light interrupter is directly radiated onto a porous material having a woven net or steel scrubber shape, thin wires of the porous material repeatedly rapidly thermally-expand and contract, whereby air in the space between the wires is momentarily heated and cooled, and the expansion and contraction of air is directly transmitted to an air column formed just adjacent to the porous material. By virtue of the above structure, the efficiency of the generator is markedly improved compared to the conventional technique, and the productivity is also greatly enhanced.
