  • Patent number: 9161441
    Abstract: The present invention provides a glass cloth suitable for producing a printed wiring board to be used in the electronics and electric fields, which has small anisotropy in dimensional change and is free from warpage and twist, a prepreg using said glass cloth, and a printed wiring board using said glass cloth. The glass cloth relevant to the present invention is characterized in that the warp yarn and the weft yarn are configured with a glass yarn of 1.8×10?6 kg/m to 14×10?6 kg/m, a (breadth/length) ratio of an average filament diameter of said weft yarn to an average filament diameter of said warp yarn is 1.01 or more but less than 1.27, and a thickness is 10 ?m to 40 ?m.

  • Patent number: 8952137
    Abstract: A method is provided for producing soluble thrombomodulin substantially not containing a denatured product of the soluble thrombomodulin that is generated under acidic conditions, which comprises: subjecting the soluble thrombomodulin-containing material to an anion exchanger or hydroxyapatite; and carrying out linear gradient elution, stepwise gradient elution, or gradient elution in which linear gradient elution is combined with stepwise gradient elution under separation conditions in which the denatured product of the soluble thrombomodulin can be separated, wherein the gradient is a salt concentration gradient, so as to obtain an elution fraction containing soluble thrombomodulin that does not substantially contain the denatured product of the soluble thrombomodulin, either (a) after the position of a fraction has previously been confirmed, or (b) while confirming the elution fraction.
