  • Patent number: 11453098
    Abstract: A carrier for a double-side polishing apparatus configured to double-side polish providing a semiconductor silicon wafer. The carrier being disposed between upper and lower turn tables have a polishing pad attached, and includes a holding hole formed to hold the semiconductor silicon wafer between the upper and lower turn tables during polishing. The carrier for a double-side polishing apparatus is made of a resin. An average contact angle with pure water of front and back surfaces of the carrier, which come into contact with the polishing pads, is 45° or more and 60° or less, and a difference in average contact angles between the front surface and the back surface is 5° or less, which provides a carrier for a double-side polishing apparatus capable of enhancing the polishing rate for a semiconductor silicon wafer by using a resinous carrier; and a double-side polishing apparatus and method which employ the carrier.

  • Patent number: 7928282
    Abstract: The present invention provides a substrate treated with an linked enzyme. It has been discovered that a substrate treated with a linked enzyme can be effective in improving the ability of the substrate to absorb viscoelastic materials, such as menses, by cleaving a protein structure present in some viscoelastic materials. In addition, the linked enzyme is less likely to migrate from the treated material onto the user, as compare to an enzyme being placed directly on the substrate, thereby reducing the risk of sensitization to the user of the absorbent product. Also provided by the present invention are absorbent articles which contain at least one surface or layer containing the linked enzyme.

  • Patent number: 6734124
    Abstract: Coated inflatable fabrics and more particularly concerns airbag cushions to which very low add-on amounts of silicone-based coating have been applied and which exhibit extremely low air permeability are provided. The inventive inflatable fabrics are primarily for use in automotive restraint cushions that require low permeability characteristics (such as side curtain airbags). Traditionally, heavy, and thus expensive, coatings of compounds such as neoprene, silicones, and the like, have been utilized to provide such required low permeability. The inventive fabric utilizes an inexpensive, very thin, substantially uniform silicone coating to provide such necessarily low permeability levels. Thus, the inventive coating comprises at least a single layer comprising a majority of silicone-based material, wherein the total thickness of the single layer is at most about 3.0 ounces per square yard as applied to a target fabric surface.

  • Patent number: 6294487
    Abstract: The present invention relates to an airbag fabric which is woven in such a manner as to possess a cover factor of less than about 1900 but which simultaneously, through the presence of a film (laminate) or coating, possesses an extremely low air permeability. The utilization of such a loosely constructed fabric within airbag cushions has heretofore not been possible, even with the application of standard airbag coatings (such as silicones) over the fabric surface since such coatings with not easily remain in contact over the loosely constructed fabric surface (i.e., the coating would leak through the fabric). The coupling of a low cover factor fabric with a laminate film (or with a coating wherein the cover factor is at least 1600), however, solves such a problem and permits the utilization of inexpensively produced woven fabrics within airbag applications.
