<p><P>PROBLEM TO BE SOLVED: To materialize the visualization of exact, simple ultrasonic vibration heating. <P>SOLUTION: In the ultrasonic vibration heating, prescribed members 4a and 4b are vibrated ultrasonically by an ultrasonic horn 7 to generate heat. A plane illuminant 3 having heat luminescence properties are made to approach or contact the heat generation parts 6 of the members 4a and 4b to emit light so that the application effect of the ultrasonic vibration is monitored. The members 4a and 4b are at least two joined materials 4a and 4b joined to each other. The heat generation parts are joint parts 6 comprising the joining faces 6a and 6b of the joined materials 4a and 4b which are laid to overlap each other to be joined together by welding. The joint condition of the joint parts 6 is monitored. The joined materials are transparent or opaque plastic materials 4a and 4b. <P>COPYRIGHT: (C)2004,JPO</p> |
