  • Patent number: 8541321
    Abstract: A copolymerized polyether polyamide resin for coating on or for impregnation to a woven or knitted fabric, wherein elongation and elastic modulus of the copolymerized polyether polyamide resin are not less than 1000% and not more than 15 MPa, respectively. The copolymerized polyether polyamide resin has a constitution wherein said copolymerized polyether polyamide resin is such that a soft segment comprising a polyether polyamide constituted from a polyether diamine compound and a dicarboxylic acid compound is bonded to a hard segment comprising a polyamide constituted from an aminocarboxylic acid compound and/or a lactam compound.

  • Publication number: 20120286810
    Abstract: An object of the present invention is to accurately detect concentrations of mixtures in a fluid. An internal electrode 23 is disposed on the inner side of an external electrode 22 coaxially with the external electrode 22, and a plurality of points in the length direction of the internal electrode 23 are supported by a casing 21 via supporting members 28a and 28b. The state of a fluid S passing through a passage 26 between the external electrode 22 and the internal electrode 23 is detected based on electrostatic capacitance between the external electrode 22 and the internal electrode 23.
