| 20080283183 | PROCESS AND SYSTEM FOR MAKING NOISE ABSORBER CARPET AND A NOISE ABSORBER CARPET MADE THEREFROM - A noise absorber carpet comprised of a fabric layer portion and a resinous backing layer portion is provided. The fabric layer portion and the resinous backing layer portion are heat bonded with a press into the noise absorber carpet, and the press includes perforation pins and a cooling medium. The resinous backing layer portion is provided with noise absorbing perforations formed by contact with the perforation pins of the press and cooled by the cooling medium. The perforations having been cooled by the cooling medium with the press simultaneously with the bonding of the resinous backing layer portion with the fabric layer portion and the cooling of the press by the cooling medium, thereby providing for instant curing and fixation of the shape of the perforations. | 11-20-2008 |

| 20100122569 | GAS SENSOR PROVIDED WITH INNER AND OUTER COVERS FOR GAS SENSING ELEMENT - A gas sensor comprises a gas sensing element, a housing for the gas sensing element, and an element cover secured to an axial end of the housing and composed of an inner cover covering part of the gas sensing element and an outer cover disposed outside the inner cover. The outer cover comprise an approximately cylindrical side wall body, a bottom body integral with the side wall body, and a guide having first and second ends, the first end being secured to the side wall body and the second end being separated from the side wall body and located to provide a side opening between the second end and the side wall body. The side opening introduces a gas thereinto. A discharge opening is formed through the bottom body. The second end is recessed inward in the outer cover and is closer to the bottom body than the first end. | 05-20-2010 |

| 20090269734 | METHOD FOR DETERMINATION OF RECOGNITION SPECIFICITY OF VIRUS FOR RECEPTOR SUGAR CHAIN - A method in which the recognition specificity of a virus for a receptor sugar chain can be easily determined with a simple instrument or apparatus is provided. In a method for determining the recognition specificity of a virus for a receptor sugar chain or for determining the change in a host infected in accordance with the mutation of virus comprising, a sample of the virus is brought into contact with a support having a polymer with sialo-oligosaccharide immobilized on the surface thereof; and the degree of binding therein is assayed to determine the recognition specificity of said virus for said receptor sugar chain and to determine the change in a host range. The method is suitable for the surveillance of virus. | 10-29-2009 |
