ULTRASONIC WAVE FLOATING DEVICE AND METHOD, AND ULTRASONIC WAVE SUCKING DEVICE AND METHOD

摘要

PROBLEM TO BE SOLVED: To stably and surely float a floated object with a simple constitution, to easily increase its floating quantity, and to stably and surely suck a sucked object even in the atmospheric air with a simple constitution. SOLUTION: This ultrasonic wave floating device 1 comprises an ultrasonic wave generating unit 2, and a radiating member 3 vibrated by ultrasonic wave generated by the ultrasonic wave generating unit 2. The radiating member 3 has a flat radiation face 3a, and a recessed part 3b recessed with respect to the radiation face 3a. Whereby the floating quantity of the floated object can be increased, and the floated object can be stably and surely floated on the radiating member 3. COPYRIGHT: (C)2003,JPO
