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

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.

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).

Abstract: A device for cooling a turbine casing in a turbomachine including a turbine is disclosed. The turbine includes several stages, at least one of the stages includes a nozzle assembly formed of an annular row of fixed vanes and an impeller mounted to rotate in a cylindrical shroud formed of ring sectors fixed to the casing, a cooling circuit including ducts carrying cooling air into cavities formed in the vanes of the nozzle assembly, and an air-carrying arrangement which carries air to casing upstream hooks for suspending the ring sectors.

Abstract: An assembly includes a vane and a cooling liner for cooling the vane, the vane having a central cavity with at least one first opening into which the liner extends, the liner having a flange fixed to the rim of the opening. This assembly includes, near the flange, a peripheral insert inserted between the wall of the liner and the wall of the opening.

Abstract: A bladed stator sector for a turbo-engine reduces the occurrence of thermally-induced stress cracks in stator blades by increasing the flexibility of the sectors by using one or more cutouts. The stator sector includes at least one stator blade between inner and outer platforms and at least one flange on one or more of the platforms. Each flange has a first end portion fixed to one of the platforms and a second end portion that is not fixed to either of the platforms. The one or more cutouts may be located on the flange and may be non-opening.
