20090056540 | APPARATUS AND METHOD FOR SEPARATING GAS - An apparatus and a method for separating a specified gas from a gas to be treated containing the specified gas comprising at least one ingredient, which comprises allowing the gas to be treated to flow through a column without the use of another gas for transferring the gas to be treated, while keeping the inside of the column packed with a packing material at a reduced pressure. The above apparatus and method can be suitably used for separating a specified gas having a high purity at a low cost. | 03-05-2009 |
20080312350 | Crosslinked aromatic polymer electrolyte membrane and method for producing same - An aromatic polymer film substrate, or a grafted aromatic polymer film substrate having a monomer introduced therein as graft chains is irradiated with ionizing radiation to impart a crosslinked structure. The aromatic polymer film substrate or the grafted aromatic polymer film substrate, provided with the crosslinked structure, is directly sulfonated to obtain a crosslinked aromatic polymer electrolyte membrane. The crosslinked aromatic polymer electrolyte membrane has low water uptake, high proton conductivity, low methanol permeability, high chemical stability, and excellent mechanical characteristics. A method for producing the crosslinked aromatic polymer electrolyte membrane is also provided. | 12-18-2008 |
20080304523 | Method of increasing the contrast of a high-intensity laser - In the improved method for increasing the contrast of a high-intensity laser, signal light outputted from a laser oscillator, a preamplifier or the like is amplified by OPCPA which is excited by pump light having a short pulse width comparable to that of the signal light, thereby producing an extremely high contrast. | 12-11-2008 |
20080283388 | Hydrogen gas detecting membrane - An optical hydrogen gas detecting membrane is prepared by sequentially depositing a platinum oxide layer and a catalytic metal layer on a transparent substrate, such as quartz glass, by vapor deposition such as the sputtering method. Palladium or platinum is used as the catalytic metal layer. | 11-20-2008 |
20080199756 | Polymer electrolyte membranes comprising alkyl graft chains and a process for producing the same - Polymer electrolyte membranes for use in fuel cells are produced by first graft polymerizing acrylic acid derivatives or vinylketone derivatives as monomers on polymer substrates and by then performing selective conversion to a sulfonic acid group of hydrogen atoms on the carbon atom adjacent to the carbonyl in the ketone or carboxyl group on the graft chains. | 08-21-2008 |
