The invention claimed is: 1. An apparatus for preventing growth of microbia propagating themselves on an internal wall of a waterline of a dental unit or for removing the microbia, comprising: electric signal generating means for generating an electric signal including an audio frequency component;
The invention claimed is: 1. An apparatus for preventing growth of microbia propagating themselves on an internal wall of a waterline of a dental unit or for removing the microbia, comprising: electric signal generating means for generating an electric signal including an audio frequency component; a transponder including a coil and a case for housing the coil; and means for attaching the transponder to an external wall of the waterline, wherein the electric signal is applied to the coil so that an audio electronic signal to be sent through the waterline can be generated. 2. The apparatus according to claim 1, wherein the electric signal frequency-modulates around a predetermined frequency. 3. The apparatus according to claim 2, wherein the audio electronic signal includes a harmonics component by the frequency modulation. 4. The apparatus according to claim 3, wherein the predetermined frequency is between 1500 Hz and 2500 Hz. 5. The apparatus according to claim 3, wherein a face of the transponder which comes in contact with the waterline has a concave shape whose section is circular. 6. The apparatus according to claim 2, wherein the predetermined frequency is between 1500 Hz and 2500 Hz. 7. The apparatus according to claim 6, wherein a face of the transponder which comes in contact with the waterline has a concave shape whose section is circular. 8. The apparatus according to claim 6, wherein the transponder is attached near an end of the waterline. 9. The apparatus according to claim 2, wherein a face of the transponder which comes in contact with the waterline has a concave shape whose section is circular. 10. The apparatus according to claim 1, wherein a face of the transponder which comes in contact with the waterline has a concave shape whose section is circular. 11. The apparatus according to claim 1, wherein the transponder is attached near an end of the waterline. 12. The apparatus according to claim 2, wherein the transponder is attached near an end of the waterline. 13. A method for preventing growth of microbia propagating themselves on an internal wall of a waterline of a dental unit or for removing the microbia, comprising the steps of: generating an electric signal including an audio frequency component; attaching a transponder including a coil and a case for housing the coil to an external wall of the waterline; and applying the electric signal to the coil, thereby generating an audio electronic signal to be sent through the waterline. 14. The method according to claim 13, wherein the electric signal frequency-modulates around a predetermined frequency. 15. The method according to claim 14, wherein the audio electronic signal includes a harmonics component by the frequency modulation. 16. The method according to claim 14, wherein the predetermined frequency is between 1500 Hz and 2500 Hz. 17. The method according to claim 16, wherein a face of the transponder which comes in contact with the waterline has a concave shape whose section is circular. 18. The method according to claim 16, wherein the transponder is attached near an end of the waterline. 19. The method according to claim 13, wherein a face of the transponder which comes in contact with the waterline has a concave shape whose section is circular. 20. The method according to claim 13, wherein the transponder is attached near an end of the waterline.
