Title: Method of polishing ceramic plate
Inventor: ITO MASABUMI
IPC: B24B37/30
Filed: 1992-06-03
Abstract: PURPOSE:To facilitate the removal of a ceramic plate fixed to a surface plate so as to enhance the productivity by setting the ceramic plate on the surface plate on which liquid is sprayed, then by allowing the liquid to solidify so that the ceramic plate is fixed to the surface plate, and by polishing the ceramic plate in this condition. CONSTITUTION:During polishing of a relatively thin ceramic plate such as a glass substrate, the ceramic plate is at first set on a surface plate on which liquid is sprayed, and then the liquid is solidified. As the liquid, water or alcohol which can be readily turned into a solid phase from the liquid phase and vice versa, is used. Further, upon fixing of the ceramic plate to the surface plate, ultraviolet curing resin or thermoplastic resin can be used. In the case of using such resin, the ultraviolet curing resin or the thermoplastic resin is sprayed on the surface plate, and the ceramic plate is set thereon. Thereafter, ultraviolet rays are irradiated onto the ultraviolet curing resin, or the thermoplastic resin is heated and annealed so as to fix the ceramic plate onto the surface plate.

IPC: H04N19/126
Filed: 1997-06-25
Abstract: PROBLEM TO BE SOLVED: To suppress the generation of false colors in image data to a minimum, when image compressing/expansion processing is performed by setting the compressibility with respect to chrominance data to be higher than the compressibility with respect to luminance data when determining the compressibility. SOLUTION: A DRAM 4 stores gamma corrected and white balanced image data. A CPU 5 finds an optimum image compressibility, and based on that compressibility, the image data stored in the DRAM 4 are compressed and written in a flash memory 6. Furthermore, the CPU 5 prepares image data in three primary colors over all the pixels by interpolating image data in two colors omitted for each pixel from peripheral image data, while using R, G and B image data stored in the DRAM 4. Further, based on a data size evaluation value, the compressibility with respect to the chrominance data and to the luminance data is determined, so that the compressibility to the chrominance data in the image data can be higher than the compressibility to the luminance data.
