    摘要: A process for continuously preparing benzophenone-azines comprising oxidizing benzophenone-imines with molecular oxygen or a molecular oxygen-containing gas in the presence of a copper halide catalyst is disclosed. The oxidation reaction is carried out in a multistage system under an oxygen partial pressure gradually decreasing from the former stage to the latter stage and at a conversion gradually decreasing from the former stage to the latter stage, while controlling the conversion so that the molar ratio of the benzophenone-imines to the copper halide in the final stage be maintained at 1 or more. By the process, the continuous reaction can stably be performed at a high conversion of the benzophenone-imines without involving insolubilization and sedimentation of the catalyst.

    摘要: A slide switch that can remove foreign particles, such as metallic dust, from its ground terminals. When the movable contact slides toward a stroke end, the power source contact first passes through an end section of the power source terminal before disengaging the terminal. At that instant, arcs are generated between the contact and the terminal. Arcs produce metallic dust, carbide particles, etc. that adhere to the insulator and terminals creating buildup and obstructing the sliding path of the contacts. The switch is provided with a discharge hole and arc gaps along the sliding path of the contacts to eliminate the arc buildup. The contacts carry the metallic dust and carbide particles while sliding so that the dust and particles drop into the discharge hole or arc gap.

    摘要: The present invention provides a melanin that is excellent in coloring a functional film, and in reproducibility and stability during storage, and a method for its production. Also, the invention provides a functional film containing a melanin and its method for production. Specifically, it provides a functional film containing a melanin of which the alteration is improved and which is excellent in the property for protecting eyes from ultraviolet rays, and in its method for production.The method for producing a melanin of the present invention, comprises, at least, under controlled conditions, a step for an oxidative reaction wherein a melanin precursor is continuously oxidized while the mole ratio of the melanin precursor relative to the oxidative agent is maintained at a constant ratio, and a step for precipitation wherein a melanin is precipitated by acidifying a reaction solution after the step for an oxidative reaction.
