  • Patent number: 11972594
    Abstract: A multifunction peripheral includes a color number conversion determiner. The color number conversion determiner determines whether it is appropriate to perform either an index color process or a full-color process based on a color distribution degree, which is a distribution degree of pixel values of the respective sets of pixel data included in input image data, a photograph area ratio, which is a ratio of photograph area pixel data forming a photograph area to the pixel data, and a color uniformity area ratio, which is a ratio of white base area pixel data forming a white base area to the pixel data.

  • Publication number: 20190330140
    Abstract: A compound used in the conventional enzymatic reactions and mass spectrometry methods needs to be altered with respect to the structure thereof as a substrate compound, such as the length of an alkyl chain contained therein, depending on the type of a target enzyme, and therefore has the problem that the conditions for the mass spectrometry on a product compound are undesirably varied and the sensitivity is deteriorated. In the present invention, a compound is provided, which can be used in an enzymatic reaction and a microanalysis method both for detecting a trace component stably and with high sensitivity. The compound according to the present invention is characterized by having a nitrogen atom, an amide bond and a glycosidic bond at specific sites, respectively, has high reactivity with an enzyme, and can provide a compound capable of being detected very easily with a mass spectrometer.

  • Patent number: 9234312
    Abstract: A sizing agent for a reinforcement fiber is used for reinforcing thermoplastic matrix resins and spreads on the reinforcement fiber surface and imparts both excellent splittability and bonding performance to thermoplastic matrix resins. The sizing agent includes essentially an ester compound (A) having a vinyl ester group, acrylate group or methacrylate group bonded to at least one of the chain ends of the main chain of the ester compound (A), and of a polyoxyalkylene alkyl ether (B) which is an adduct between an alkylene oxide and a C4-14 monohydric alcohol. When water is added to the sizing agent thereby producing a mixture with a nonvolatile content of 1 weight %, the mixture exhibits a dynamic surface tension ranging from 40 to 55 mN/m determined by the maximum bubble pressure method when bubbles are blown into the mixture at the rate of one bubble per 100 milliseconds.
