  • Publication number: 20240076426
    Abstract: The present invention relates to resin particles including a residue unit represented by the following general formula (1) and having a volume average particle diameter equal to or more than 5 ?m and equal to or less than 2008 ?m, and a method for producing thereof. Fruthermore the present invention relates to a fluororesin comprising a residue unit represented by a general formula (1) and having a weight average molecular weight Mw in a range of 5×104 to 3×105, and a yellow index of a heat-melted molded product (thickness 3 mm) after 24 h at 280° C. of equal to or less than 6, and a method for producing thereof. In the formula (1), Rf1, Rf2, Rf3, and Rf4 are each independently one of the groups consisting of a fluorine atom, a linear perfluoroalkyl group having 1 to 7 carbon atoms, a branched perfluoroalkyl group having 3 to 7 carbon atoms, or a cyclic perfluoroalkyl group having 3 to 7 carbon atoms. The perfluoroalkyl group may have an ethereal oxygen atom.

  • Patent number: 5846211
    Abstract: An occlusal force-meter 1 includes an occlusal force detecting portion 2 for detecting an occlusal force and a main body 3 for processing the detected signal obtained by the occlusal force detecting portion 2 to display the occlusal force measured value on a display 4. The occlusal force detecting portion 2 includes a transmitting portion (second pressure transmitting portion) 5 having diaphragm portions 7, 8 at an upper surface and/or a lower surface of one end portion 5f thereof. A pressure medium liquid L is filed therein, for transmitting the occlusal force added to the diaphragm portions 7, 8 to a pressure detector 9 disposed on the other end portion 5r thereof.

  • Patent number: 5131390
    Abstract: A device for continuously measuring the skin local sweating rate includes a capsule used for applying on a human skin at a measuring point and an air supply element for supplying dehumidified air to the capsule. A first chamber is formed between the capsule and the skin for receiving water vapor perspired from the skin and the dehumidified air supplied from the air supply element to produce the mixture of perspiration oriented water vapor through the skin and the dehumidified air. A second chamber is also formed within the capsule and connected with the first chamber through a communicating hole. The device further includes a humidity detecting element disposed in the second chamber. The humidity detecting element varies its electrical circuit constant according to the relative humidity of the mixture. A temperature detecting element is disposed in the second chamber for detecting the temperature in the second chamber and for outputting signals corresponding to the temperature.
