A hard coat layer on which adhered fingerprints are inconspicuous is provided. The hard coat layer 1 consists of a cured product. The cured product is formed by curing a curable composition by irradiating it with an ultraviolet ray. The curable composition contains a curable resin. The curable resin contains reactive monomers. The reactive monomers contain an isocyanuric acid derivative. The isocyanuric acid derivative is preferably tri(meth)acrylate of an ethylene oxide and ε-caprolactone adduct of isocyanuric acid.

Multifunction production equipment enabling a plurality of processes in which deposition of reaction products on the inner wall of the processing chamber of equipment for producing a semiconductor or a flat-plate display, metal contamination due to corrosion of the inner wall, or the like, and fluctuation of the process due to discharged gas are suppressed, and a protective film structure for use therein. On the surface of a metal material, a first coating layer having an oxide coating of 1μ thick or less formed as an underlying layer by direct oxidation of a parent material, and a second coating layer of about 200 μm thick are formed. With such an arrangement, corrosion resistance against irradiation with ions or radicals can be imparted to a second layer protective film, and the effect of a protective layer for preventing corrosion of the surface of parent metal caused by diffusing molecules or ions into the second layer protective film can be imparted to the first layer oxide film. Consequently, contamination of the substrate with metals generated from each metal member and the inner surface of the process chamber is reduced, and stripping of the second layer protective film due to lowering in adhesion of the second layer protective film due to corrosion of the interface between the parent material and the second layer protective film can be suppressed.

It has been difficult to provide a large-sized ceramic member quickly and economically. A multilayer structure is produced by forming a ceramic film on a base which is made of a material that can be shaped comparatively easily. The ceramic film is formed by a plasma spraying method, CVD method, PVD method, sol-gel method or the like. Alternatively, the ceramic film may be formed by a method combined with a spray deposit film.

Cavitation is produced through injection of pressurized water from an injection outlet of an injection nozzle 17a toward the pavement surface in liquid of a liquid storage part T1 formed on the pavement surface. A clogging object in a cavity of a pavement is isolated by impactive force of the cavitation, and the isolated clogging object is removed by suction with water.
