Abstract: A plastic film contains, as a main component, a poly(alkylene-2,5-furandicarboxylate) and has a thickness of 1 mm or less. Even when the plastic film is used in a single layer without being laminated, the plastic film has excellent gas barrier properties against oxygen, carbon dioxide, and water vapor and excellent moisture resistance and corrosion resistance.

Abstract: An image coding method that compresses an image read through an optical system. An image separation section carries out image area decisions in tile (macro block) units to separate the image into photographic image tiles and character image tiles. A layer separation section performs layer separation pixel by pixel to separate each pixel into pixels belonging to a background and pixels belonging to a foreground. Approximation processors alleviate an increase of entropy, due to layer separation through approximation processing, and carry out JPEG-like processing on photographic images.

Abstract: By allowing cellulose and a base to coexist in water at a reaction temperature of not less than 150° C. but less than 400° C. at a pressure of 5 MPa or more, the cellulose is directly degraded into lactic acid. The weight ratio of the base relative to the cellulose is within the range from 0.5 to 8.

Abstract: An arithmetic decoding apparatus is provided that carries out complete pipeline processing. Fluctuations in the pipeline caused by occurrence of the normalization are resolved by using a future-predicted Qe memory. In coding multi-valued images, common contexts are generated without distinguishing between AC and DC components of DCT coefficients.

Abstract: An arithmetic coding apparatus for carrying out complete pipeline processing is provided. This arithmetic coding apparatus analyzes an input image, reads image information accurately and performs arithmetic coding at ultra-high speed. Using a future prediction type Qe memory removes disturbance in the pipeline caused by renormalization. The arithmetic coding apparatus also generates a common context when coding multi-valued images without distinguishing between an AC component and DC component of a DCT coefficient. The apparatus is also provided with a circuit for outputting an arithmetic code which is a variable-length code with the length fixed to facilitate editing of a reconstructed image.
