  • Publication number: 20090238995
    Abstract: The present invention provides a sheet-like plasma generator in which film deposition area can be enlarged while making the film thickness distribution more uniform, and film deposition equipment employing such sheet-like plasma generator. The sheet-like plasma generator generates sheet-like plasma by passing a plasma beam, which let out from a plasma gun by means of a convergence coil, through a magnetic field formed by a sheet magnet assembly consisting of a pair of sheet magnets in the form of permanent magnets extending in the direction perpendicular to the advancing direction of the plasma beam and arranged in parallel to oppose each other, and deforming the plasma beam into a sheet-like plasma beam. The sheet magnet assembly includes at least one sheet magnet in which the repulsion field strength at a portion corresponding to the central side of the plasma beams is higher than that at a portion corresponding to the outer edge side of the plasma beam.

  • Patent number: 7375225
    Abstract: 4-Cyanocoumarin derivatives which have a distinct sensitivity to visible light, distinct luminescent ability, and satisfactory applicability for photochemical polymerization, dye lasers, and organic electroluminescent elements. Since most of the derivatives have a fluorescent maximum wavelength of 600 to 650 nm, particularly, 610 to 630 nm, they are extremely useful as luminescent agents for organic EL elements which emit visible light in a red-color region, and can be quite useful as luminescent agents in organic EL elements and laser-active substances in dye lasers, as well as luminous bodies as lighting sources for lighting devices, and information displays for visually displaying information.
