Abstract: PROBLEM TO BE SOLVED: To improve the utilization efficiency of ultraviolet light and visible light and to display a high-luminance image by forming an ultraviolet luminescent element, dielectric films transmitting the ultraviolet light and reflecting the visible light, and a wavelength converting film converting the ultraviolet light into the visible light in this order on a substrate. SOLUTION: A first conductive film 3, a first insulating film 4, an ultraviolet luminescent film 5, a second insulating film 6, a second conductive film 7, a first dielectric film 8, a wavelength converting film 9 and a second dielectric film 10 are laminated in this order on a substrate 2 to form a luminescent element 1. An ultraviolet EL element is constituted of the first conductive film 3, the first insulating film 4, the ultraviolet luminescent film 5, the second insulating film 6 and the second conductive film 7. When the electric field is applied between the first conductive film 3 and the second conductive film 7, the ultraviolet luminescent film 5 emits ultraviolet light. When the emitted ultraviolet light is fed to the wavelength converting film 9, visible light is emitted. This visible light is emitted to the outside from the outward principal plane 10a of the second dielectric film 10.

Abstract: PURPOSE:To enable the magneto-optical recording at a high density and high speed transfer rate by diminishing an area of such a part in a magneto-optical recording medium that its temp. is to be more than the Curie temp. CONSTITUTION:A light spot in a recording part position of a prependicular magnetization film 3 to be formed by a laser beam SHG passing through a dichroic mirror and a light spot in a recording part position of the prependicular magnetization film 3 to be formed by a laser beam LD reflected by the dichroic mirror 13 are matched in position so as to be coincident in both the radial direction and the track direction of an optical disk 1. In this case, since the laser beam LD capable of changing its light intensity at a low level or a high level and the laser beam SHG of a comparatively short wavelength film 3 in the optical disk 1 becomes fine, and hence the width of a magnetization pit can be small, so that the track density can be promoted. By this method, the magneto-optical recording at a high density and high speed transfer rate is feasible.

Abstract: PURPOSE:To inexpensively obtain an image of high horizontal resolution by deflecting a laser beam obtained by converting a pattern information signal into a pattern information signal having frequency higher than a prescribed frequency and modulating the converted signal in the horizontal direction. CONSTITUTION:The laser plotter is provided with a converting means 1 for reading out a pattern information signal Va with a prescribed frequency f1 sent at a fixed period T at a period ts faster than the period T and converting the read signal Va into a pattern information signal V having frequency f2 higher than the frequency f1 and a horizontally deflecting means 6 for horizontally deflecting the laser beam l modulated by the signal component of the signal V. Since the laser beam l modulated by the signal component of the signal V having the higher frequency, a horizontal blanking period can be extended without changing the prescribed one-horizontal scanning period and a margin can be applied to the fly-back line of the laser beam l. Consequently, the beam diameter D can be increased and an image of high resolution can be obtained.

Abstract: PROBLEM TO BE SOLVED: To achieve high density recording of an optical disk having an information recording layer formed by using an organic material. SOLUTION: A dielectric layer 4 consisting of a nitride layer 7 and an oxide layer 8 successively laminated is formed on the information recording layer 3 and a light transmission layer 5 is stuck onto the dielectric layer 4 via an adhesive agent. Since the dielectric layer 4 is formed between the information recording layer 3 and the light transmission layer 5, the organic material forming the information recording layer 3 is not diffused to the adhesive agent used for sticking the light transmission layer 5. Since the oxide layer 8 is formed on the nitride layer 7, the information recording layer 3 is not deteriorated by the oxygen plasma generated when the oxide layer 8 is formed. Since the nitride layer 7 is specified to have
