  • Patent number: 9043676
    Abstract: Data is compressed using content addressable memory without disruption despite error using a plurality of content addressable memories to detect sequentially repeating data elements of the data. Compression information is generated for each sequence of repeating data elements that repeat for at least a compression threshold without any one of the plurality of content addressable memories generating an indication of an error for a matching content addressable memory entry. Individual data elements are output for each of the data elements that do not repeat for the compression threshold. Compression information is generated for each sequence of repeating data elements that repeat for at least the compression threshold and then generating a currently searched data element that matches the repeating data elements when any one of the plurality of content addressable memories generates an indication of an error for a content addressable memory entry that matches the currently searched data element.

    Abstract: A method for decoding encoded data includes receiving data encoded by replacing each of a plurality of characters with bit strings. The method also includes recording, on the basis of definition information, at least one of the characters as corresponding to each of the bit lengths, and generating decode information based on the number of characters, wherein the decode information includes bit string information for sorting the bit strings in a bit length order that is a predetermined order associated with bit lengths. The method also includes, in response to receiving a particular bit length, generating character information in which the characters are sorted in the bit length order by inserting a character corresponding to the particular bit length into a position corresponding to the particular bit length in an array in which at least one of the bit lengths.

  • Patent number: 6969771
    Abstract: A process for producing a processed glyceride having a satisfactory color tone and having high purity without the need of a fractionation step, by mitigating the deterioration in a color tone caused by the processing and recycling of a fatty acid ester recovered after an interesterification reaction. The process comprises subjecting a glyceride fat and a fatty acid ester and/or a free fatty acid to interesterification, distilling the reaction product to recover a part or all of fatty acid esters and/or free fatty acids therein, subjecting the distillation fraction recovered to hydrogenation, and to re-distillation or mixing with the fresh fatty acid ester and/or fresh free fatty acid in any order, re-reacting the resultant fraction or mixture with the distillation residue, and separating a fat fraction from the final reaction product, and is characterized in that the content of components other than the fatty acid ester and/or free fatty acid is controlled to 3.0 wt. % or lower.
