    摘要: 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.

    摘要: 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.
