    • A clear color image having a high contrast ratio without particular coloration is displayed on a screen by improved display apparatus. Such display apparatus is comprised of a spatial light modulator including a photo-conductive layer, a photo-modulator layer and a dielectric mirror, a device for writing color images of different colors onto the spatial light modulator time-divisionally in a sequence of the different colors, a reading device for producing reading lights having different colors in synchronism with time-divisional writing of the color images, and for projecting the reading lights to the spatial light modulator, a driving device for supplying the spatial light modulator with different voltages and frequencies correspondingly with the reading light of different colors and in synchronism with time-divisional projections of the reading lights, and a device for projecting the color images read out from the spatial light modulator on the display device.The dielectric mirror may have a light absorbance characteristic controlled to be wavelength-selective to absorb a color of light to which the photo-conductive layer is most sensitive, so that lights having different colors leaked into the photo-conductive layer through the dielectric mirror are controlled to cause a uniform impedance of the photo-conductive layer.
    • 通过改进的显示装置在屏幕上显示具有没有特定着色的高对比度的清晰彩色图像。 这种显示装置由包括光电导层,光调制层和电介质镜的空间光调制器组成,用于将不同颜色的彩色图像分时地以不同的顺序分列在空间光调制器上的装置 颜色,用于产生与彩色图像的分时写入同步的具有不同颜色的读取光并且用于将读取光投影到空间光调制器的读取装置,用于向不同的电压和频率提供空间光调制器的驱动装置 对应于不同颜色的读取光并且与读取灯的时分投影同步,以及用于将从空间光调制器读出的彩色图像投影到显示装置上的装置。 电介质镜可以具有被控制为波长选择性以吸收光敏层最敏感的光的颜色的光吸收特性,使得具有不同颜色的光通过电介质镜泄漏到光导层中 被控制以导致光导层的均匀阻抗。

    • The present invention relates to a multiplexer/demultiplexer for use in mobile communication devices and provides a small and low-loss multiplexer/demultiplexer. The present invention provides a multiplexer/demultiplexer including a first to a third ports each externally terminated with a pure resistance, in which the second port is made to be a common port by connecting between the first port and the ground a first resonant circuit which makes serial resonance at a frequency within a first frequency band or in its proximity, and further connecting an inductive element in series between the first port and the second port, and connecting between the third port and the ground a second resonant circuit which makes serial resonance at a frequency within a second frequency band which is different from the first frequency band or in its proximity, and further connecting a capacitive element in series between the third port and the second port.
