Title: Digital array re-indexing method and digital data compressor
Inventor: ZENG WENJUN
IPC: H04N1/64
Filed: 2000-11-14
Abstract: PROBLEM TO BE SOLVED: To provide a digital array re-indexing method and a digital data compressor capable of compressing efficiently a palletized image. SOLUTION: In this method and compressor, a pallet-indexed image is re- indexed by using an array of a symbol cross count which displays the frequencies in occurrence of one or more determined context relations in the image, for example, one or more symbols adjacent to each other. The pallet index is operated so as to assign an index as near as possible to the symbol adjacent to it in the symbol space, then the compression characteristics of the image caused by many no-loss compressors is enhanced. In the above method, a pool 102 of one dimensional re-assignment and a seeded symbol assigned to a seeded position 104 are in usage, and according to a potential function using a cross count array, one symbol is selected to locate a position at right or left, position in the pool 102.  By the repetition of this process, while the next choice, a first and a second pool symbol are analyzed, and the symbol is input into the pool 102 so as to minimize the average difference of pixels in the re-indexed image.

Title: Foreign matter removing method for liquid crystal device
Inventor: NORIMATSU TSUTOMU
IPC: G02F1/1337
Filed: 2000-11-27
Abstract: PROBLEM TO BE SOLVED: To reliably remove a foreign matter without damaging an alignment layer even when the foreign matter is adhered to a tape or the like. SOLUTION: A liquid organic coating film is applied onto the alignment layer in a step S21. The organic coating film encloses the foreign matter on the alignment layer. A tape for removing dust is stuck to the organic coating film (a step S23) after the organic coating film is dried (a step S22). The tape is pressed to the organic coating film by a roller in a step S24. Even if a foreign matter is adhered to the tape when the tape is pressed, the damage of the alignment layer is prevented by the function of the organic coating film as a buffer material. When the tape is peeled, the organic coating film is peeled from the alignment layer and the foreign matter on the alignment layer is removed in the peeling process in a step S25.
