20100273003 | RESIN COMPOSITION, PREPREG, AND LAMINATE - A resin composition used to prepare a sheet-like prepreg by impregnating a substrate with the resin composition includes an epoxy resin that contains a naphthalene-modified epoxy resin, and a triazine-modified novolac resin. A sheet-like prepreg is formed by impregnating a substrate with the resin composition. A laminate formed using the prepreg exhibits excellent flame retardancy, solder heat resistance, and lead-free heat resistance, has a small coefficient of linear expansion in the thickness direction, and has excellent adhesion to a conductor circuit. | 10-28-2010 |
20100279114 | PREPREG MANUFACTURING METHOD AND PREPREG - The invention offers a method of manufacturing a prepreg capable of impregnating a fiber substrate with a liquid resin with a high degree of impregnation, and a prepreg obtained by this method. The invention is a method of manufacturing a prepreg by impregnating a long fiber substrate with a liquid resin using a kiss roller whose bottom portion is immersed in a liquid resin, including a step of impregnating the fiber substrate with a liquid resin from one surface thereof, by conveying the fiber substrate while maintaining contact with a circumferential surface of the kiss roller which is not immersed in resin, and performing this step at least twice in succession, and a prepreg obtained by this manufacturing method. | 11-04-2010 |
20120111621 | RESIN COMPOSITION, RESIN SHEET, PREPREG, METAL-CLAD LAMINATE, PRINTED WIRING BOARD AND SEMICONDUCTOR DEVICE - An object of the present invention is to provide a resin composition having excellent impregnation property into a base material and capable of producing a prepreg, metal-clad laminate and printed wiring board excellent in properties such as low warpage, flame resistance, low thermal expansion properties, drill processability and desmear resistance. A first resin composition comprises an epoxy resin, an irregular-shaped first inorganic filler and a second inorganic filler having an average particle diameter of 10 to 100 nm which is different from that of the first inorganic filler. A second resin composition comprises an epoxy resin, silicone rubber particles having an average particle diameter of 1 μm to 10 μm, boehmite particles having an average particle diameter of 0.2 μm to 5 μm, and silica nanoparticles having an average particle diameter of 10 nm to 100 nm. | 05-10-2012 |

20150260720 | METHOD AND KIT FOR DISTINGUISHING BETWEEN PROSTATE CARCINOMA AND BENIGN PROSTATIC HYPERPLASIA - An object of the present invention is to provide a method for distinguishing between prostate carcinoma and benign prostatic hyperplasia with high sensitivity and good reproducibility using a small amount of an analyte sample. The method for distinguishing between prostate carcinoma and benign prostatic hyperplasia according to the present invention as a solution means thereof comprises: bringing an analyte sample containing a prostate-specific antigen (PSA) into contact with a carrier having an anti-free PSA antibody immobilized thereon, thereby binding free PSA to the anti-free PSA antibody immobilized on the carrier; thereafter bringing the carrier in which the free PSA is bound to the immobilized anti-free PSA antibody into contact with a monoclonal antibody capable of specifically recognizing a glycan in which a terminal sialic acid residue is bound to galactose through an α(2,3) bond, thereby binding the monoclonal antibody capable of specifically recognizing a glycan in which a terminal sialic acid residue is bound to galactose through an α(2,3) bond to the free PSA bound to the anti-free PSA antibody immobilized on the carrier; measuring the amount of the free PSA having an N-type glycan in which a terminal sialic acid residue is bound to galactose through an α(2,3) bond; comparing the measured amount thus obtained with a preset cutoff value for prostate carcinoma and benign prostatic hyperplasia, thereby determining that when the measured amount is larger than the cutoff value, prostate carcinoma is developed or the probability of developing prostate carcinoma is high, and when the measured amount is smaller than the cutoff value, benign prostatic hyperplasia is developed or the probability of developing benign prostatic hyperplasia is high. | 09-17-2015 |
