  • Patent number: 8557376
    Abstract: A polishing pad which suppresses occurrence of a scratch or a roll-off on an object to be polished so that flatness is improved is provided. A polishing pad 1 is comprised a polyurethane sheet 2 having a polishing surface P for performing polishing processing to an object to be polished and an elastic sheet 3 having elasticity joined on a surface of the polyurethane sheet 2 on the opposite side to the polishing surface P. The polyurethane sheet 2 is set higher in compressibility than the elastic sheet 3, and is set lower in A hardness than the elastic sheet 3. The elastic sheet 3 is set at 1% or more in compressibility, and is set at 90 degrees or less in A hardness. Further, both of the polyurethane sheet 2 and the elastic sheet 3 are formed to have a thickness of 0.2 mm or more. The flexibility of the polyurethane sheet 2 is exerted during polishing processing so that the polyurethane sheet 2 deforms to press the polishing surface P approximately evenly on the object to be polished.

  • Patent number: 7823416
    Abstract: The glass composition of the present invention is an inorganic glass composition in which the volume ratio of helium with a mass number of 3 to helium with a mass number of 4, namely 3He/4He in the glass (0° C., 1 atm) is smaller than the volume ratio 3He/4He in the atmosphere. The method of producing a glass article of the present invention includes the steps of: melting a glass raw material by heating; homogenizing molten glass; forming the molten glass into a desired shape; and cooling the shaped glass to room temperature, in which helium with a certain mass ratio is dissolved in the glass material so that the glass article of the present invention is obtained.
