    • A magneto-optical recording medium comprises a substrate, a magneto-optical recording layer formed of a rare earth metal-transition metal alloy and a dielectric protective layer overlaid in this order on the substrate, and a rare earth metal layer overlaid on an edge face of the magneto-optical recording layer. The magneto-optical recording medium wherein the substrate is annular is made by forming the magneto-optical recording layer, covering the recording region on the magneto-optical recording layer with an annular mask having an outer diameter not larger than the outer diameter of the magneto-optical recording layer and/or an inner diameter not smaller than the inner diameter of the magneto-optical recording layer, overlaying the rare earth metal layer on an outer edge face and/or an inner edge face of the magneto-optical recording layer by dispersing rare earth metal particles toward the annular mask, removing the annular mask, and overlaying the dielectric protective layer on the magneto-optical recording layer.

    • A projector of a reflection type has a Fresnel lens disposed under a stage surface on which a transparency is set. A light source is disposed under the Fresnel lens, and illuminates the stage surface through the Fresnel lens. An illuminating mirror is disposed in a position higher than the stage surface, reflects light passed through the transparency after emanation from the light source, and illuminates the transparency downwards. A projection lens projects an image of the transparency via the Fresnel lens to a screen. A liquid crystal display (LCD) panel is disposed so that the stage surface lies thereon, and displays an image to be projected to the screen. The LCD panel is transparent when the transparency is set on the stage surface, and enables projection of the image.
    • 反射型的投影仪具有设置在其上设置有透明度的台面下方的菲涅尔透镜。 光源设置在菲涅尔透镜下方,并通过菲涅尔透镜照亮舞台表面。 将照明镜设置在高于舞台表面的位置,反射从光源发出后通过透明物的光,并将透明度向下照亮。 投影透镜通过菲涅耳透镜将透明物的图像投影到屏幕。 设置液晶显示器(LCD)面板,使得台面位于其上,并且显示要投影到屏幕的图像。 当透明度设置在舞台表面上时,LCD面板是透明的,并且可以投影图像。

    • An overhead projector has a stage on which original material is placed. The stage has a Fresnel mirror. An electrostatic attracting structure is integral with the Fresnel mirror. The attracting structure includes a conductive membrane of ceramic and a resinous dielectric/protective layer. The conductive membrane consists of a pair of comb-shaped electrodes, which interfinger in coplanar fashion, and are covered by the dielectric/protective layer for insulation and protection. A power supply device applies a high voltage of direct current to the electrodes. The original material is attracted electrostatically by the electrodes, and can be kept flat on the stage. In a preferred embodiment, the power supply device incorporates a self-starting blocking oscillator, which is adapted to boost the voltage sufficiently for electrostatic attraction.
    • 高架投影仪具有放置原始材料的阶段。 舞台上有菲涅尔镜。 静电吸引结构与菲涅尔反射镜是一体的。 吸引结构包括陶瓷的导电膜和树脂电介质/保护层。 导电膜由一对梳状电极组成,其共同的方式连接在一起,并被绝缘和保护的电介质/保护层覆盖。 电源装置向电极施加高电压的直流电。 原材料被电极静电吸引,并可在平台上保持平坦。 在优选实施例中,电源装置包括自启动阻塞振荡器,其适于将电压充分提升以用于静电吸引。
