  • Patent number: 11945984
    Abstract: A reinforcing film comprises a pressure sensitive adhesive layer laminated and fixed on a principal surface of a film substrate. The pressure sensitive adhesive layer is formed of a photocurable composition containing a photocurable agent and a base polymer having a crosslinked structure. The gel fraction of the photocurable composition is preferably 60% or more. The shear storage elastic modulus at 25° C. of the pressure sensitive adhesive layer is preferably 1×104 to 1.2×105 Pa. The shear storage elastic modulus at 25° C. of the pressure sensitive adhesive layer after photocuring is preferably 1.5×105 to 2×106 Pa.

  • Patent number: 7221476
    Abstract: A picture image processing apparatus is provided with a hue calculating portion for calculating a hue pixel by pixel based on RGB data, a first sampling portion for sampling pixels having a hue corresponding to a skin color from the RGB data, a first characteristic quantity calculating portion for calculating a first characteristic quantity representing a characteristic of the RGB data of the pixels, a second sampling portion for sampling the pixels located in a central part of an image area, a second characteristic quantity calculating portion for calculating a second characteristic quantity representing the RGB data of the pixels sampled by the second sampling portion, a correction amount calculating portion for calculating a density correction amount using the first and second characteristic quantities, and a density correcting portion for correcting the density of the RGB data. The density of a main subject in the image can be properly corrected.

  • Patent number: 4542064
    Abstract: The self-bonding enameled wire has an electric insulation layer coated thereon and a bonding layer coated over the insulation layer. The bonding layer is prepared with a mixture including: (a) 100 parts by weight of a phenoxy resin and/or an epoxy resin, both the resins containing not larger than 5 ppm of sodium chloride and having a limiting viscosity of not less than 0.440 as measured in tetrahydrofuran solvent at 25.degree. C.; and (b) 20 to 100 weight parts of a n-butylated melamine resin. In place of this n-butylated melamine resin, there is, according to another aspect of the present invention, used 20 to 50 parts by weight of a mixture of a stabilized polyisocyanate and one of a n-butylated melamine resin and a benzoguanamine resin is used. These self-bonding enameled wire are excellent in refrigerant resistance and may be suitably used for windings of a stator coil in hermetic compressor motors.
