  • Emulsion composition
    Patent number: 11179333
    Abstract: Provided is an emulsion composition that allows a lipophilic ingredient to have high stability and high in vivo absorbability. The emulsion composition includes (a) a lipophilic ingredient, (b) a phospholipid, (c) a polyol, (d) water, (e) a sucrose fatty acid ester, and (f) a polyglycerol fatty acid ester. The content of the phospholipid (b) is from 2.0 to 15.0 parts by weight to 100 parts by weight of the total of the emulsion composition, and the weight ratio of the (f) polyglycerol fatty acid ester to the (e) sucrose fatty acid ester is from 0.1 to 0.9 parts by weight of the (f) polyglycerol fatty acid ester to 1 part by weight of the (e) sucrose fatty acid ester.

  • Method and apparatus for measuring internal defects for position and depth
    Patent number: 5196716
    Abstract: A method for measuring internal defects of a specimen, comprising the steps of allowing a finely focused laser beam to be incident into a specimen from its surface and observing the scattered light of the said laser beam from inside the said specimen from the surface of the specimen and in a different direction to the optical axis of incidence of the laser beam.

  • Method for quantitative evaluation method of optical absorption image for determination of resistivity dispersion
    Patent number: 5077475
    Abstract: Disclosed is a quantitative evaluation method of optical absorption image which applies rays of light to a sample to obtain a quantitative optical absorption image without using destructive inspection and which can measure automatically and easily the dispersion of resistivity of the sample by calculating the mean value and standard deviation of the quantitative optical absorption image.
