    摘要： A projection optical system which has a short total length but can project a high quality and large image. The projection optical system projects the displayed image on an image displaying surface onto a projection surface, and includes a lens system having a plurality of lenses, and one or more curved mirrors. Light flux of an enlarged image shooting out from the lens system to the projection surface is incident onto a mirror surface of the one of the curved mirrors first of all. A distance OAL and a distance Y satisfy a requirement (1) 20

    摘要： A process for the continuous preparation of aniline by hydrogenating nitrobenzene with hydrogen is disclosed which comprises the steps of suspending, in an aniline solvent, a catalyst of palladium or palladium-platinum which is deposited on a lipophilic carbon having an oil absorbency of at least 100, and carrying out reaction at a temperature of from 150.degree. to 250.degree. C. substantially in the absence of water while aniline and water formed in said reaction are continuously distilled off as vapor from the reaction product, and the concentration of nitrobenzene in the reaction solution is maintained at 0.01% by weight or less, wherein a zinc compound is added to the reaction system as a promotor and carbon monoxide is added to the hydrogen at a concentration of 1-500 ppm.

    摘要： An improved process is provided for the production of chlorine. In a fluidized-bed reactor having a specific equivalent diameter and made of a material with a particular iron content, hydrogen chloride and oxygen are reacted in particular gas volumes and at specific molar ratio, superficial velocity, temperature and pressure in the presence of a catalyst composed principally of a chromium oxide and having a specific particle size distribution. The catalyst is filled in a specific amount in terms of catalyst layer height at rest. The catalyst can retain its high activity.

    摘要： A gaseous mixture containing chlorine, carbon dioxide and non-condensable gas is compressed and cooled to separate it into a residual gas formed principally of a major portion of the non-condensable gas and a condensate formed primarily of chlorine. The condensate is fed to a stripping column to desorb carbon dioxide and a minor portion of the non-condensable gas dissolved in the condensate. The stripped gas formed primarily of chlorine and carbon dioxide may be treated further. Namely, the stripped gas is mixed with the residual gas. At least a portion of the mixed gas is fed into an absorption column, whereby a major portion of remaining chlorine is absorbed to lower the chlorine content Removal of chlorine from such a gaseous mixture or an off-gas from the above process can be achieved by washing it with an aqueous solution or suspension containing an alkali metal sulfite and/or an alkaline earth metal sulfite while controlling the pH of the solution or suspension within a range of 1.9-6.3.
