    • An oil-based ink for piezoelectric inkjet printers contains a binder resin, a pigment and a solvent. The solvent contains a cyclic ester and a compound represented by the following formula (1): wherein X1 represents an alkyl group, X2 represents a hydrogen atom or an alkyl group, and n stands for an integer of from 1 to 4. The amount of the cyclic ester is from 1 to 60 parts by weight per 100 parts by weight of the compound represented by the formula (1). Preferably, the cyclic ester is a compound represented by the following formula (2): wherein X3 and X4 each independently represents a hydrogen atom or a C1-7 alkyl or alkenyl group, and m stands for an integer of from 1 to 3.

    • There are provided a data compression apparatus and a data compression program capable of performing new and preferable compression processing applicable to compression of CT data. They are provided with: a thinning processing section which creates, by cyclically thinning out a numeric value from the sequence of numeric values constituting the data to be compressed, first data to be compressed which is constituted by a sequence of the numeric values taken out from the data to be compressed by the thinning out, and second data to be compressed which is constituted by a sequence of the remaining numeric values; a lossless compression section which performs lossless compression processing for the first data to be compressed which has been created by the thinning processing section; and a lossy compression section which performs lossy compression processing for the second data to be compressed which has been created by the thinning processing section.
    • 提供了能够执行适用于CT数据的压缩的新的和优选的压缩处理的数据压缩装置和数据压缩程序。 它们具有:细化处理部分,其通过从构成要压缩的数据的数值的序列周期性地稀疏数值来创建要被压缩的第一数据,其由从 要通过稀疏化压缩的数据和由剩余数值序列构成的第二待压缩数据; 无损压缩部,对由所述稀疏处理部创建的所述第一待压缩数据进行无损压缩处理; 以及对由所述间断处理部创建的要被压缩的第二数据进行有损压缩处理的有损压缩部。
