Abstract

DC60 ultrasonic transducer For birth and transmission of power Ultrasonic work With a predefined frequency To the surface of the object in one skeletal system, resonators are inserted between the head masses. And crystals that carry a voltage Resonators are made of materials. Sound velocity Equal to or greater than an object, which should be a ceramic like silicon carbide. Or alumina oxide In another skeletal system, the head mass and the tail mass. Still made of ceramic material too Ultrasonic transducers For generating and transmitting ultrasonic energy With a predefined frequency To the surface of the object In one skeletal system, resonators are inserted between the head masses. And crystals that carry a voltage Resonators are made of materials. Sound velocity Equal to or greater than an object, which should be a ceramic like silicon carbide. Or alumina oxide In another skeletal system, the head mass and the tail mass. Still made of ceramic material too

Claims (10)

1.

Device under claim 1, where the ceramic material of the resonant-enhancing disc is alumina ceramic. 3. A device for generating and transmitting ultrasonic energy, consisting of a base, a voltage-bearing material, a resonant disc positioned between the base and the voltage-bearing material (where the resonant disc is made of ceramic), the first electrode positioned between the resonant disc and the voltage-bearing insulator, the second electrode positioned between the resonant disc and the insulator, and a reflector positioned along the top edge on the side without the second electrode. 4. Device under claim 3 where the ceramic material of the resonant-enhancing disc is alumina ceramic. 5. An apparatus for generating and transmitting ultrasonic energy, consisting of a metal base, an electrically charged crystal, a resonant disc positioned between the base and the charged material (the resonant disc being made of ceramic), a first electrode positioned between the resonant disc and the charged material, a dielectric insulator, a second metal electrode positioned between the resonant disc and the dielectric insulator, and a steel resonator positioned next to the dielectric insulator on the side without the second metal electrode. 6. Device under claim 5 where the electrically charged seal consists of lead, verconate titanate. 7. Device under claim 5, where the material of the resonant-enhancing disc is alumina ceramic. 8. A device for generating and transmitting ultrasonic energy, consisting of a base, a ceramic disc with one side in contact with the base, an electrically charged spherical crystal positioned against the ceramic disc on the opposite side of the base, electrode paths for supplying power to the charged crystal, and a reflector positioned against the charged crystal on the opposite side of the ceramic disc. 9. The device under claim 8, which consists of a threaded base, a ceramic disc, an electrically charged crystal, and a through-hole reflector, where the ceramic disc, the electrically charged crystal, and the reflectors are stacked on the base and further secured by bolts that extend through the holes of the reflectors, the electrically charged crystal, and the ceramic disc and are threaded into the threaded holes of the base to firmly secure the stack to the base. 10. Device under claim 8, whereby a ceramic disc is made of alumina ceramic.
