20130078472 | VULCANIZATION-ADHERED LAMINATE OF FLUORORUBBER AND SYNTHETIC RUBBER - A vulcanization-adhered laminate is constituted by a structure where a fluororubber layer and a synthetic rubber-containing layer are tightly adhered by vulcanization by vulcanization, and the synthetic rubber layer prior to the vulcanization-adhesion includes organic peroxide, silica, organic phosphonium salt, maleic anhydride-modified polybutadiene, and magnesium oxide. | 03-28-2013 |
20090274616 | ZEOLITE MEMBRANES FOR HYDROGEN GAS PRODUCTION AND METHOD OF PRODUCING HYDROGEN GAS USING THE ZEOLITE MEMBRANES - To provide a method for manufacturing zeolite membrane that has characteristics of being resistant to the reaction for a long time and in the high-temperature range, and has characteristic of long-duration hydrogen generation. The inventors of the present invention successfully produced a highly dense zeolite membrane by the steps of: evacuating the surface of porous support not adding the zeolite seed crystals dropwise, thus densely filling the seed crystals in the micropores; and applying hydrothermal treatment to the seed crystals. In addition, the inventors of the present invention confirmed that the zeolite membrane manufactured by the above methods has the characteristic of generating hydrogen for a long time. | 11-05-2009 |
