    Abstract: In a method for fabricating distributed reflection multi-layered film mirrors consisting of a plurality of laminated thin films (102 and 103) having a different refractive index, the thin films (102 and 103) are formed using a liquid phase film formation method. The liquid phase film formation method includes a step of applying thin film materials forming the thin films, and a step of drying the applied the thin film materials. The liquid phase film formation method utilizes an ink jet method. Thin films can be formed in fine patterns with ease and in a short amount of time. Laminated layers with high reliability can be obtained in very fine patterns. The reflection properties such as film thickness and reflectance of distributed reflection multi-layered film mirrors can be controlled with ease.

    Abstract: A projection display apparatus employing organic EL elements is presented that is light in weight, is small in size, and can be practically implemented. In particular, the apparatus suppresses light-emission performance degradation caused by generated heat, thereby extending useful life, stabilizing brightness, and securing continual maximum brightness. The apparatus comprises: liquid crystal panels 12R, 12G, and 12B; light emitting units 13R, 13G, and 13B, positioned at the back of the liquid crystal panels and provided with organic EL elements as light emitting layers; and cooling bodies 14R, 14G, and 14B, positioned at the back of the light emitting units, for dispersing the heat generated by the light emitting layers. The cooling bodies 14R, 14G, and 14B may, for example, be electronic cooling elements that employ the Peltier effect to absorb and radiate the generated heat. Alternatively, the cooling bodies may be configured as heat-dispersing fins that guide and disperse generated heat.

    Abstract: A magneto-optical recording and reproducing apparatus comprises coding and modulating means (11) for (1,7) RLL encoding and then NRZI encoding a digital information series äAiü; a magneto-optical drive (3) for recording said encoded series äaiü to a magneto-optical recording medium, and reproducing an analog signal from said medium as elementary waveform sequence e(t) using an optical head; a transversal filter type waveform equalizer (14) for waveform equalizing elementary waveform sequence e(t) by applying the transfer function (1 + 2D + 2d + D ) of the PR(1,2,2,1) encoding method to the elementary waveform sequence where delay operators D have a delay time of the encoded sequence cell width Tb; a low pass filter (15); an A/D converter (16) for sampling and quantizing the equalized waveform sequence x(t); and a Viterbi decoder (17) for comparing the e A/D converter output äaiü with a particular expected value, and determining the most probable path as decoding sequence äAiü. The transfer function of PR(1,2,2,1) encoding well approximates the combined transfer function of the magneto-optical drive (3) and the waveform equalizer (14), achieves strong suppression of interwaveform interference, and achieves high density recording. The Viterbi decoding means has a long minimum free distance, and an improved error correction rate.
