| 20110241924 | PROJECTION DETECTING APPARATUS AND PROJECTION DETECTING METHOD - A projection detecting apparatus according to the present invention is that for detecting a projection on a surface of a running metal object, and includes a transmission antenna for radiating electromagnetic waves; a reception antenna for receiving reflected electromagnetic waves; and a transmission and reception signal processing section for processing a transmission signal and a reception signal. The transmission antenna and the reception antenna have unidirectionality and the transmission antenna and the reception antenna are installed in such a way that the reception antenna does not catch electromagnetic waves which have been radiated by the transmission antenna and reflected on the surface of the metal object and the reception antenna catches electromagnetic waves alone which have been radiated by the transmission antenna and reflected on the projection. | 10-06-2011 |
| 20110032541 | FILM THICKNESS MEASURING DEVICE AND FILM THICKNESS MEASURING METHOD - A film thickness measuring device is provided with a light source, a spectroscopic sensor, a processor, and a storage unit, and configured in such a manner that light from the light source vertically enters a plane to be measured provided with a film and the light reflected by the plane to be measured enters the spectroscopic sensor. The storage unit stores theoretical values of reflectivity distributions of respective film thicknesses and theoretical values of color characteristic variables of the respective film thicknesses. The processor finds the thickness of the film of the plane to be measured from the reflectivity distribution measured by the spectroscopic sensor by using the theoretical values of the reflectivity distributions of the respective film thicknesses or the theoretical values of the color characteristic variables of the respective film thicknesses stored in the storage unit. | 02-10-2011 |
