Disclosed is a fluorine-containing elastomer having a copolymerization composition containing (A) 72.8 to 74.0 mol % of tetrafluoroethylene, (B) 26.8 to 24.0 mol % of perfluoro (lower alkyl vinyl ether) or perfluoro (lower alkoxy-lower alkyl vinyl ether), and (C) 0.2 to 3.0 mol % of a perfluoro unsaturated nitrile compound, and having a Mooney viscosity ML1+10 (121° C.) of 70 to 115. The fluorine-containing elastomer is compounded with a bisamidoxime compound, which is used as a vulcanizing agent, in an amount of 0.2 to 5 parts by weight based on 100 parts by weight of the fluorine-containing elastomer to form a fluorine-containing elastomer composition. The vulcanizate of the composition, even when used under plasma irradiation conditions or at temperatures as high as 300° C., can prevent weight loss caused by plasma irradiation and exhibits excellent heat resistance at temperatures as high as 300° C. or more.

摘要:
In order to perform appropriate image correction considering the moving image region and static image region of image data forming a moving image, the image data forming the moving image is input in a unit of frame, the image data is divided into a moving image region and static image region, and a feature amount of the moving image region and that of the static image region are calculated. At least one table for image correction is generated based on the feature amount of the moving image region and that of the static image region, and the image data is corrected using the table.

This invention provides a technique of preventing errors from being gradually accumulated on the decoding side, while maintaining high scalability, even when a technique for transformation to subbands as a plurality of frequency components, like discrete wavelet transformation, is used for moving image coding. The image data of one input frame is decomposed into a plurality of subbands having different frequency components by a discrete wavelet transformation unit (101). A lower bitplane coding unit (109) codes, for each bitplane, predetermined lower bits of each coefficient data of a subband LL and the coefficient data of subbands other than the subband LL. The data of the upper bits of the subband LL is stored in a frame memory (105). A motion vector detection unit (107) detects a predicted value and motion vector on the basis of the decoded data of the subband LL in a preceding frame. A subtracter (103) obtains the difference between the detected predicted value and the current frame. A coefficient coding unit (104) codes the obtained difference. A motion vector coding unit (108) codes the motion vector. A multiplexing unit (111) multiplexes the code data obtained by the coding units (104, 108, 109).

摘要:
The present invention provides a safe and highly effective antibacterial composition without impairing the flavor of foods or drinks, which composition is used in products such as foods and oral care goods which are mainly to be taken into human or animal bodies or mainly to be used in the oral cavity. The composition according to the present invention contains gallocatechin gallate as an agent for enhancing the activity of antibacterial catechins in which the antibacterial activity of the antibacterial catechins against Streptococcus mutans is particularly enhanced. The composition according to the present invention can be produced by mixing the antibacterial catechins with gallocatechin gallate. Alternatively, it can be produced as a composition comprising a synthetic adsorbent-adsorbed fraction as the main component, which is obtained by subjecting a solvent-extract from tea leaves to an adsorption treatment with the use of a synthetic adsorbent selected from among aromatic compound-based synthetic adsorbents and methacrylic compound-based synthetic adsorbents.
