In the decurling method, the multi-layer film is transported. A first transition of the support layer in the multi-layer film being transported into a rubber phase is induced by supplying fluid vapor on the support layer. After supplying the fluid vapor, a second transition of the support layer from the rubber phase into a glass phase is induced. The multi-layer film is transported while a portion of the support layer in the rubber phase is prevented from contacting a solid object. The hard coat layer is formed from a polymer produced from an ultraviolet curable compound, and the support layer is formed from cellulose acylate.

  • Patent number: 8845948
    Abstract: Three-dimensional microstereolithographic objects fabricated by microstereolithography are exposed to UV light for one hour to accelerate hardening. The structures are then heated at 175° C. or above for at least 6 hours. The heating temperature may exceed the glass transition temperature, which is the index of thermal softening temperature of materials. The present invention relates to three-dimensional microstructures formed by microstereolithography. Deformation due to a structure's own weight, which generally poses a problem in heat treatment, is reduced with microstructures due to the size effect. As a result, the dimensions of the three-dimensional structure fabricated by the present invention remain almost unchanged before and after the heat treatment.

  • Patent number: 8790554
    Abstract: A method of preparing meta-aramid fibers includes the operations of polymerization, neutralization and spinning using m-phenylenediamine and isophthaloyl chloride as raw materials, wherein the neutralizing agent is added in an amount that is sufficient only for neutralizing a part of hydrogen chloride, so that the resultant spin dope of polyisophthaloyl metaphenylene diamine contains salts produced by the neutralization reaction and a part of unneutralized hydrogen chloride. The method of the invention has a short production line with reduced amount of the neutralizing agent, therefore both the costs of raw materials and the production energy consumption are saved. The fibers prepared according to the method of the invention have reduced gray scale to improve the electrical insulation properties of the fibers.
