  • Mattress
    Patent number: 8745797
    Abstract: The objective of the present invention is to provide a mattress including a plurality of cells provided on a body pressure working surface of a substrate that supports a human body, and a pressure control means that changes a setting of a height of each cell by adjusting a pressure in a fluid chamber formed within the cell. An elastic cushion layer is provided on a body pressure working surface of the cells, and a constricted portion is formed in a middle in the height of the each cell so that the body pressure working surface of the cell is allowed to tilt following deformation of the cushion layer as a result of the cells' precession-deformation at the constricted portion.
    Type: Grant

  • Production of aliphatic copolyesters
    Patent number: 5652325
    Abstract: Aliphatic polyester copolymers, which have molecular weights high enough for practical use and which are excellent in thermal stability, tensile strength and moldability, and which are biodegradable as well, are provided, which are produced by a process comprising effecting polycondensation of an aliphatic diol and an aliphatic dicarboxylic acid in the presence of an aliphatic monohydroxymonocarboxylic acid in a specific amount and of a catalyst comprising a germanium compound.
