Title: Protective layer reinforced composite waterproof structure
Inventor: NOJIMA MASAHIRO
IPC: E04D7/00
Filed: 1998-02-06
Abstract: PROBLEM TO BE SOLVED: To improve a function by arranging a nonslip work-applied fiber reinforced thermosetting resin protective layer on a waterproof layer composed of a polyurethane resin on a base body. SOLUTION: A paint film waterproof layer composed of a polyurethane layer is formed on a base body such as mortar placed in reinforced concrete or the like. Next, for example, a protective layer is formed by applying a thermosetting resin on it when necessary by placing a reinforced fiber mat before hardening after applying a liquid thermosetting resin on the paint film waterproof layer. In that case, nonslip work having an increased friction coefficient is applied by increasing the surface area by forming a large number of recesses/projections on the protective layer surface by laying them on the waterproof layer by putting the recess/projection surface on the upside by prearranging a large number of recesses/projections on the surface of the reinforced fiber mat.  Therefore, waterproof performance can be improved since the waterproof layer extends by following a crack of the base body, durability can be improved since the protective layer has strong impact resistance and weatherability, and safety of walking, vehicle travel or the like at rainfall time can be also secured.

Abstract: PURPOSE:To minimize the damage of a break in a high speed region by judging a break occurred in a metal strip when fluctuation of a tension actual value is continued for a preset time within a preset width. CONSTITUTION:Tension of a metal strip 10 is controlled by a rotational speed of a payoff reel 11, and an automatic tension control unit 20 for controlling this rotational speed inputs a tension actual value, measured by a tension meter 19 arranged in an outlet side of an annealing processing both 12, via a signal wire 20a. A tension command value is inputted via a signal wire 20b, and an electric motor 16C is controlled to hold the tension of the metal strip 10 to a specific value. When a fluctuating width of the tension actual value is within a preset width B to continue fluctuating time for a specified preset time T, the metal strip 10 is judged to break. In this way, brake damage in a high speed region can be suppressed to minimize.

Filed: 1994-03-11
Abstract: PURPOSE: To prevent the failure of a fiber and to improve a yield by removing the contaminated particles of a density and size larger than those of the suspended particles in sol in accordance with the characteristics thereof before this sol is gelatinized.  
     CONSTITUTION: The silica base optical fiber is drawn from a preform contg. sol-gel forming glass of which the sol contains the SiO 2  suspended particles in water. In such optical fiber forming method, the contaminated particles of the density and size larger than those of the SiO 2  suspended particles included in the sol, more particularly ZrO 2  and TiO 2  particles, are removed from the sol. The settlement dependent upon the density and the filtration based on the size are useful for separating such harmful particles from the SiO 2  particles constituting the water-soluble sol. The preferable method is a method by centrifugal force which puts the water-soluble gel into a bottle 10 mounted at a rotor arm 11 connected to a rotor 12 and rotates the same, thereby separating the harmful particles as precipitate 13.

Title: Radiation curable composition
Inventor: TEIMOSHII JIYOSEFU DORANATSUKU
IPC: C08G77/38
Filed: 1984-03-02
Abstract: This invention relates to a process for reacting a compound containing silicon-bonded hydrogen with a compound containing aliphatic unsaturation in the presence of actinic radiation and to compositions that contain an actinic radiation-sensitive catalyst that are useful in the process. Although many platinum complexes are useful as catalysts in processes for accelerating the thermallyactivated addition reaction between compounds containing silicon-bonded hydrogen and compounds containing aliphatic unsaturation, processes for accelerating the ultraviolet radiation activated addition reaction between these compounds, using a platinum complex as a catalyst, are not known. The ultraviolet radiation activated addition radiation can be conducted in the presence of a platinum complex having an ultraviolet displaceable group, e.g. a ( -diolefin) (-aryl) platinum complex. This process is useful for the in situ curing of a polymeric silicone composition to a solid surface, particularly one which is heat-sensitive.
