摘要:
Packaging for reliably fixing an irregularly shaped ink ribbon unit includes few components, including a printing paper roll wound with printing paper, an ink ribbon unit having both a sending roll that is wound with an ink ribbon and a winding roll disposed in parallel to the sending roll, a container for holding the printing paper roll and ink ribbon unit, and a partition member that partitions the container into first and second storage regions, into which the printing paper roll and ink ribbon unit are respectively stored. The ink ribbon unit is arranged in such a manner that the direction of the shafts of the sending and winding rolls is parallel to the bottom surface of the second storage region, and the partition member extends with an inclination relative to a direction perpendicular to the bottom surface of the second storage region.

An encoded-data converting apparatus and method are provided. First encoded data generated by using first encoding to encode image data is input. Header information included in the first encoded data is extracted. Header information based on second encoding is generated from the header information included in the first encoded data. Variable-length-code conversion is set up based on a predetermined parameter for use in the second encoding and an encoding parameter used in the first encoding. Encoded data in one frame is extracted from the first encoded data. A variable length code in the encoded data in the frame is converted in accordance with the variable-length-code conversion. DC components in the encoded data in the frame are decoded into quantized values and the quantized values are used to perform predictive encoding based on the second encoding. The obtained outputs are shaped and output as data encoded by the second encoding.

摘要:
The present invention is drawn to a screw compressor having a wide operating range with respect to flow rate and pressure ratio, wherein a discharge opening portion of a casing is provided with a generally tapered notch portion so that compressed gas is gradually discharged from a certain fixed point where a volume ratio of one groove defined by rotors and the casing is smaller than an inherent built-in volume ratio. Since the present invention is arranged in the above-mentioned manner, the flow of the gas at the discharge opening portion is reduced by the notch portion which is readily formed. Thereby the variation range of the pressure (the amplitude of pulsation of the pressure) is decreased and the noise level is lowered. Further, a loss of pressure resulting from the rapid flow of the gas is restricted to thereby widen a range of preferable performance of the compressor.

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.
