    摘要： A color cathode ray tube comprises a panel having an effective portion. The outer surface in the effective portion of the panel is substantially flat or forms a slightly curved plane with a small curvature. The inner surface of the panel has a substantially infinite curvature radius in a direction of the longer axis in at least a central portion of the panel and is curved in a direction of the shorter axis. A difference in thickness of the effective portion of the panel between the central portion and the edge portions diagonally apart from each other exceeds 8 mm and does not exceed 20 mm, and the transmittance of the glass in the central portion of the effective portion is at least 70%. The particular construction enables the vacuum envelope of the color cathode ray tube to exhibit a mechanical strength high enough to sufficiently withstand the atmospheric pressure, though the effective portion of the panel is flattened. The vacuum envelope also exhibits a mechanical strength high enough to hold the curved surface of the shadow mask. Further, deterioration of brightness can be prevented in the color cathode ray tube of the present invention.

    摘要： A rhodopsin family protein is inserted into an etalon type cavity having partially reflecting mirrors as principal components having a reflectivity of 50% to less than 100% for light having a wavelength in the 650-800 nm region and a transmissivity of 30% or more for light having a wavelength in the 400-600 nm region to form a photo-controlled spatial modulator. By utilizing a change in the refractive index by light of the photo-sensitive protein, near infrared light of a stronger intensity can be controlled by weaker visible light, and the information contained in the light signal on a two-dimension plane can be rapidly controlled by a light signal of weaker intensity of another two-dimension plane by using an optical switch of a simple construction.
