  • Publication number: 20230417670
    Abstract: A method for determining UV coverage on an irradiation target in real time comprises the steps of irradiating an irradiation target (10) with light including UV light (16) immediately after applying a sunscreen (12); detecting an amount of fluorescent light (20) emitted from the irradiation target in response to the light irradiation and storing the amount of the fluorescent light as reference data; irradiating the irradiation target (10) with the light including UV light (16) after a predetermined passage of time, or after applying a predetermined stress on the sunscreen (12); detecting an amount of fluorescent light (20) emitted from the irradiation target in response to the light irradiation and storing the amount of the fluorescent light as measurement data; and determining UV coverage by dividing the amount of the fluorescent light of the reference data by the amount of the fluorescent light of the measurement data, wherein the irradiation target (10) includes at least one substance emitting fluorescent

  • Patent number: 9786576
    Abstract: A positive-type photosensitive resin composition includes (A) a phenol resin modified by a compound having an unsaturated hydrocarbon group having 4 to 100 carbon atoms; (B) a compound that produces an acid by light; (C) a thermal crosslinking agent; and (D) a solvent. The positive-type photosensitive resin composition according to the present invention can be developed by an alkaline aqueous solution, and an effect thereof is that a resist pattern having sufficiently high sensitivity and resolution, excellent adhesion, and good thermal shock resistance can be formed.

  • Publication number: 20160159665
    Abstract: This system (18) comprises a holding and separating tank (36), an inlet (38) for moving untreated waste water into the holding tank (36), and a bubble generator (32), able to introduce a quantity of bubbles into the waste water of the holding tank (36), in order to form, in a lower region (50) of the holding tank (36), a treated water and, in an upper region (52) of the holding tank (36), a supernatant. The system (18) comprises a lower outlet (40) for recovering a treated water from the holding tank (36) and an upper outlet (42) for discharging a foamy supernatant from the holding tank (36). The system (18) is devoid of means for injecting a compound for flocculating and/or coagulating the waste water, at least upstream from the holding tank (36).
