    摘要： A photo-electric converter principally constructed with a photo-electric conversion unit wherein m.times.n photo-electric conversion elements, each having a light receiving window to form a pel and constructed with a layer of light receiving body and two electrodes provided on both sides thereof, are arranged two-dimensionally in an array of m ranks and n files, and wherein the light receiving windows of the photo-electric conversion elements constituting a rank are arranged at an equally spaced pitch of an integral multiple of that of pels. A signal processing circuit processes and produces as an output a signal which has been subjected to the photo-electric conversion in the photo-electric conversion unit.

    摘要： An aromatic urethane of high quality and excellent heat stability can be produced in high yield by reacting an aromatic nitro compound, a hydroxyl group-containing organic compound and carbon monoxide in the presence of a catalytic system composed of (1) palladium, ruthenium, rhodium or a compound thereof, (2) a Lewis acid, and (3) ammonia. The use of such catalytic system can suppress undesirable side reactions to a satisfactory extent and ensures the reaction to proceed without causing any corrosion of a stainless steel reactor. If necessary, water may be added to the reaction system to increase the reaction velocity, by which the unit cost of the catalyst can be reduced.

    摘要： A method for the preparation of a halogenated aromatic amine, wherein a halogenated aromatic nitro compound is hydrogenated in liquid phase in the presence of a platinum-base catalyst to obtain a corresponding halogenated aromatic amine, the hydrogenation being carried out in the presence of an alkylmonoamine, an alicyclic amine or a polyalkylenepolyamine. The presence of the amine well suppresses a dehalogenation reaction which would otherwise be involved, so that not only a high purity halogenated aromatic amine is obtained, but also corrosion of a reactor is prevented.

    摘要： A process for preparing 1-aminoanthraquinone having high purity, which comprises either1. hydrogenating 1-nitroanthraquinone in an aqueous medium in the presence of a base using a hydrogenating catalyst, and then oxidizing the hydrogenation product, or2. hydrogenating crude 1-nitroanthraquinone containing dinitroanthraquinones as impurities or crude 1-aminoanthraquinone containing diaminoanthraquinones as impurities in an aqueous medium in the presence of a base using a hydrogenating catalyst, stopping the hydrogenation at a time when the 1-nitroanthraquinone or 1-aminoanthraquinone has been substantially reduced to 1-aminoanthrahydroquinone but the dinitroanthraquinones or diaminoanthraquinones remain substantially unreduced to diaminoanthrahydroquinones, removing water-insoluble materials from the reaction mixture, and then oxidizing the remaining water-soluble residue.
