Abstract: PROBLEM TO BE SOLVED: To firmly apply a sealing material to any constructed body, especially, even if its resin-coated surface is hardly bonded like a fluororesin-coated one, by applying the sealing material directly to the constructed body after flame treatment thereof. SOLUTION: When a sealing metal is applied to a constructed surface of a constructed body such as a building for giving watertight and airtight characteristics thereto, the sealing material is applied to the constructed surface of the constructed body directly or through a primer after flame treatment. As for the flame treatment, a method in which methane, ethane, propane, butane, or the like is used as a combustion gas is desirable. As for the sealing material, for example, a silicone series, a modified silicone series, a polysulfide series, a polyurethane series, etc., are used. And as for the primer, a material which can improve an adhesive property between the sealing material and the constructed surface is used, for example, a silane coupling agent, a polyisocyanate, an epoxy resin, etc., are enumerated.

Abstract: PROBLEM TO BE SOLVED: To prevent the peeling of a coating agent and the paper washing of a solvent and to cure the coating agent in a short period of time by directly heating once the entire outer peripheral surface of a steel pipe to a specific temp. or above, then applying the coating agent on the steel pipe where the outer peripheral surface temp. is at a specific temp. range during transportation. SOLUTION: The entire outer peripheral surface of the steel pipe 2 transported in an axial direction at a speed of, for example, 60 to 90 m/min on a roller table 1 is directly heated by the burner flames of ring burners 3 until a temp. above 100 deg.C is once attained. The outer peripheral surface temp. of the once heated steel pipe 2 falls in the process that the steel pipe is transported on the roller table 1, where the outer peripheral surface temp. attains 50 to 70 deg.C, then the coating agent 5 is sprayed to the steel pipe from a coating agent spraying device 4 installed downstream of the ring burners 3. As a result, the factors to adversely influence the coating, such as moisture and dust, are removed by the burner flames and the peeling of the coating agent 5 is eliminated. The drying time of the coating agent 5 is thus shortened.

Abstract: PROBLEM TO BE SOLVED: To obtain wettability small in dispersion by linearly and relatively moving a flame burner and an object to be coated at an almost fixed speed while keeping almost constant a distance between the flame burner and a face to be coated. SOLUTION: The distance between a flame burner 30 and a 2nd surface 6 of a bumper 2 is defined as L and in the state of turning the fire burner 30 downwards, the flame burner 30 is linearly moved at fixed speed in the front/rear direction. Next, the bumper 2 is turned about at 90 deg. with a rotary shaft 13 as a center and moved upwards and sideways and in the state of turning the flame burner 30 downwards while keeping the distance L between the flame burner 30 and a 1st surface 5, the fine burner is linearly moved at fixed speed in the front/rear direction. Further, the flame burner 30 is linearly moved at fixed speed in the front/rear direction while keeping the distance L between the flame burner 30 and a 3rd face 7 after the bumper 2 is turned around the rotary shaft 13 just at a required angle and moved upwards and sideways.

Abstract: Sheet material is given low oxygen permeability or prepared for winding high voltage capacitors by evaporating polyfunctional acrylate monomer having a molecular rate in the range of from 150 to 600 and condensing the acrylate as a monomer film on a dielectric or thermoplastic substrate. The acrylate is polymerized by irradiation by ultraviolet or electrons. A metallized layer provides an electrode of a capacitor. Electrical contact can be made to the metal layer by Schooping even though the metallized layer is covered by a layer of acrylate. A material selected from the group consisting of silicon oxide, silicon nitride, aluminum nitride, titanium nitride, aluminum oxide and metal may be deposited for forming an oxygen barrier. Adhesion is enhanced by plasma treatment of a surface immediately before deposition. Condensation efficiency is also enhanced by chilling the substrate on which the acrylate is condensed.

Abstract: PURPOSE: To uniformly apply a liquid saturant without compression on a permeable sheet over the entire part thereof by applying a curtain of the liquid saturant to the continuously progressed permeable sheet and applying a vacuum thereto, then sucking the liquid saturant via the permeable sheet. CONSTITUTION: The liquid saturant 12 is first delivered from a feed supply roll 14 and is passed through a nip 16 of an S roll mechanism 18 within an inverted S-shaped passage when a continuous method 10 of uniformly applying the liquid saturant without compression to the permeable sheet 12 over the entire part thereof is performed. The permeable sheet 12 is then supplied to a means 20 for continuously progressing the sheet during the time of a liquid saturant treating state. In succession, the permeable sheet 12 is passed through a means 22 for applying the curtain flowing in a laminar form of the liquid saturant. This means 22 comprises a liquid dispensing element 24. A means 26 for applying the vacuum to the permeable sheet 12 is disposed near the liquid dispensing element 24. This means 26 comprises a vacuum element 28. The permeable sheet 28 is thereafter progressed to a drying stage.
