  • Patent number: 10619074
    Abstract: A curing process of an ultraviolet curable paint by which a paint cured layer can be formed on an object to be processed without needing a long time, and intended color can be obtained of the object to be processed on which the paint cured layer is formed. The curing process of an ultraviolet curable paint is one for curing an ultraviolet curable paint through an ultraviolet irradiation step of irradiating a surface of an object to be processed to which the ultraviolet curable paint is applied with ultraviolet rays from an ultraviolet radiation unit. The ultraviolet curable paint is not sensitive to light of not less than 380 nm in wavelength but sensitive to light of less than 380 nm in wavelength. The ultraviolet radiation unit radiates ultraviolet rays having a peak wavelength within a range of not greater than 350 nm in wavelength.

  • Patent number: 9125283
    Abstract: A light source apparatus is adapted to be shared by excimer lamps. An IC tag is disposed at each lamp, and the IC tag stores information identifying the lamp. A storage unit of the light source apparatus stores information identifying a usable lamp (or usable lamps) for the light source apparatus, an emission wavelength of the lamp, and a sensitivity correction value of an optical sensor that corresponds to the emission wavelength. When the light source apparatus is driven to cause the lamp to light, the information stored in the IC tag and information stored in the storage unit are collated and it is determined whether the lamp is usable and the emission wavelength of the lamp is a preset emission wavelength. If it is determined that the lamp is usable and the emission wavelength is appropriate, the sensitivity of the optical sensor is corrected with the correction value.

  • Patent number: 5666026
    Abstract: A dielectric barrier discharge lamp having a generally cylindrical double-tube arrangement of an outer tube coaxially disposed about an inner tube, with an outer electrode disposed on an outside surface of the outer tube, an inner electrode disposed on an inside surface of the inner tube, and a discharge space provided between the outer tube and the inner tube which is filled with a discharge gas for formation of excimer molecules by dielectric barrier discharge achieves firm engagement of the inner electrode against the inner tube and a stable discharge over a long time even if part of the electrode corrodes due to the ozone produced or it wears. This is achieved by embodiments in which the inner electrode is a generally tubular part which is slit in an axial direction along the full length thereof. The tubular part can be a single cylindrically sheet having opposite longitudinally extending edges spaced from each other by a gap or overlapped.

  • Patent number: 5581152
    Abstract: In a dielectric barrier discharge lamp, in which a discharge vessel, in which a discharge gas forming "excimer" molecules is encapsulated, is provided with a dielectric provided with a netlike electrode and a window, through which the light goes, the first object of the invention is achieved by an arrangement in which a thickness of ends of the above-described netlike electrodes is greater than the average thickness of the entire electrode. Another object of the invention is achieved by an arrangement in which a holder incorporated in the discharge vessel has an outer dimension that is less than/equal to an outer dimension of the netlike electrodes. A further object of the invention is achieved by an arrangement by which the discharge vessel has a hollow cylindrical shape formed from an external tube and an internal tube and a means for hermetic sealing is arranged inside the internal tube.
