20100035516 | POLISHING METHOD AND APPARATUS - The present invention relates to a polishing method and apparatus for polishing and planarizing an object to be polished (substrate) such as a semiconductor wafer. The substrate as an object to be polished is pressed against a polishing surface on a rotating polishing table in the polishing method. During polishing of the substrate, the polishing table is rotated, and the surface, being polished, of the substrate is scanned by an eddy current sensor provided in the polishing table. An output of the eddy current sensor obtained by scanning the surface, being polished, of the substrate is monitored, and damage of the substrate is detected from a change in the output of the eddy current sensor. Further, an output of an endpoint detecting sensor obtained by scanning the surface, being polished, of the substrate is monitored, and the polishing end point is detected from a change in the output of the end point detecting sensor. After detecting the polishing end point, an output of the endpoint detecting sensor or a different sensor is monitored, and monitoring of the remaining film for detecting a film left on a part of the substrate is performed. | 02-11-2010 |

20080317482 | Image forming apparatus - A supplying roller supplies toner to a developing roller which develops the electrostatic latent image formed on a photoconductive drum. The controller controls the supply to output first and second voltages to the developing roller and supplying roller. A detector generates a signal indicative of remaining toner. The voltage controller performs voltage correction according to the signal either in a first mode where the first voltage has a smaller value when the signal has become below a reference than when the signal is above the reference, or in a second mode where the first voltage has a smaller value when the signal has become below the reference than when the signal is above the reference, and a difference between the first and second voltages has a larger value when the signal has become below the reference than when the signal is above the reference. | 12-25-2008 |
