  • Publication number: 20240093251
    Abstract: The present invention relates to a method for producing an amide compound from a nitrile compound in the presence of a biocatalyst having nitrile hydratase activity, wherein the amide compound is efficiently produced by suppressing a deactivation of the biocatalyst, and improving the rate of conversion reaction from the nitrile compound to the amide compound.

  • Patent number: 9890466
    Abstract: This method for producing a mold for nanoimprinting in which a minute bumpy structure has been formed at the surface of a roller-shaped aluminum substrate of which the surface has been machined has: a polishing step for mechanically polishing the surface of the roller-shaped aluminum substrate, of which the surface has been machined, at least until the average crystal grain size changes; and a minute bumpy structure formation step for anodizing the aluminum substrate after the polishing step and forming a minute bumpy structure. The anti-reflective article has a minute bumpy structure at the surface, and in the wavelength region of visible light, has a color difference (E*) to the origin represented in the L*a*b* color system and derived by means of formula (1) of no greater than 0.9, or a chroma (C*) determined by means of formula (2) of no greater than 0.7.

  • Patent number: 9457493
    Abstract: Provided is a method for producing a cylindrical nanoimprinting mold such that the outer peripheral surface of a cylindrical aluminum substrate is uniformly polished, and it is possible to effectively take advantage of the outer peripheral surface. The method forms an oxide film at the outer peripheral surface (14) of an aluminum substrate (10) after polishing the entire outer peripheral surface (14) of the cylindrical aluminum substrate (10) by means of a polishing body (26), wherein the polishing body (26) is moved in the axial direction to polish in a manner such that at least a portion of the polishing body (26) is protruding beyond the first end (10a) side and second end (10b) side of the aluminum substrate (10), and the portion of the polishing body (26) protruding beyond the aluminum substrate (10) is disposed on and supported by a cylindrical first support member (18); and second support member (20).

  • Patent number: 6767901
    Abstract: The present invention provides a pharmaceutical composition for application to the mucosa to be used in drug therapy comprising a water-insoluble and/or water-low soluble substance, ciclesonide, and an aqueous medium, and having an osmotic pressure of less than 290 mOsm. This composition is superior over conventional pharmaceutical compositions for application to the mucosa, due to efficient and high ciclesonide retentivity and permeability to the submucosa or the blood at the mucosa.
