Abstract
An object levitating apparatus, an object transporting apparatus, and an object levitating process are described which, simultaneous to not placing restrictions on the material and so forth of the objects handled, are able to handle objects having relatively large weights and dimensions, while also being compact in size, inexpensive, preferable in terms of safety and so forth, and easy to control.The above effects are obtained by exciting a vibrator and levitating or transporting an object above the surface of the vibrator by the radiation pressure of the sound waves of the vibrator, and in particular, since there are no vibration nodes present as a result of in-phase piston mode vibration, the dimensions of the object to be levitated and transported can be small.
