    • A high-frequency heating apparatus includes an inner casing defining a heating chamber therein, and an outer casing surrounding the inner case. A fixed waveguide is fixed on a top wall of the inner casing to guide high-frequency waves fed from a magnetron to an excitation opening. The waveguide has a step portion facing the excitation opening and located closer to the top wall than the other portion of the fixed waveguide. A motor is mounted on the step portion and has a driving shaft extending through the excitation opening into the heating chamber. A rotating waveguide, for diffusing the high-frequency waves delivered to the excitation opening and radiating the waves into the heating chamber, is disposed in the heating chamber and coupled to the driving shaft to be rotated thereby.
    • 高频加热装置包括在其中限定加热室的内壳和围绕内壳的外壳。 固定波导固定在内壳的顶壁上,以将从磁控管馈送的高频波引导到激励开口。 波导具有面向激发开口并且比固定波导的其它部分更靠近顶壁定位的台阶部分。 电动机安装在踏板部分上并具有延伸穿过激励开口进入加热室的驱动轴。 用于扩散输送到激励开口的高频波并将波浪辐射到加热室中的旋转波导设置在加热室中并联接到驱动轴以由此旋转。

    • A liquid crystal display apparatus uses a holographic optical element to split the light from a light source for generating white light to R, G and B wavelength light components. The split light components enter respective pixels of a liquid crystal cell according to the R, G and B wavelengths, thereby ensuring the display of a color image. In this liquid crystal display apparatus, unit holographic optical elements corresponding to unit pixels each consisting of R, G and B pixels are comprised of holographic optical cells for condensing respective lights of specific wavelengths on the associated pixels. Alternatively, the unit pixels are formed to have symmetrical shapes. Color filters may be provided at some of the pixels of the liquid crystal cell. Accordingly, the light incident to the pixels of the liquid crystal cell is optimized.
    • 液晶显示装置使用全息光学元件将来自用于产生白光的光源的光分离成R,G和B的波长光分量。 分光元件根据R,G,B波长进入液晶单元的各像素,由此确保彩色图像的显示。 在该液晶显示装置中,对应于由R,G和B像素组成的单位像素的单位全息光学元件由用于聚集相关像素上的特定波长的各种光的全息光学单元组成。 或者,单位像素形成为具有对称形状。 可以在液晶单元的某些像素处提供滤色器。 因此,入射到液晶单元的像素的光被优化。
