    • A novel method is proposed for concurrently producing a metallic copper powder and a valuable chloride of a metal other than copper, e.g., manganese, zinc, cobalt, nickel and tin, from a depleted aqueous etching solution containing copper (II) chloride as discharged from the etching process in the manufacture of copper-foiled printed circuit boards. The inventive method also contributes to solve the problem for the disposal of such a waste solution without causing the troubles in connection with environmental pollution. The inventive method comprises the steps of: treating the waste solution with an active carbon so as to remove organic impurities; admixing the solution with a powder, granules or flakes of the above mentioned metal so as to precipitate the copper value in the metallic form, instead, giving an aqueous solution of the chloride of the added metal; and separating the copper metal powder and the chloride solution.
    • 提出了一种新颖的方法,用于从含有氯化铜(II)的贫化水溶液中同时制备金属铜粉末和铜以外的金属(例如锰,锌,钴,镍和锡)的有价值氯化物, 在铜箔印刷电路板的制造中的蚀刻工艺。 本发明的方法还有助于解决这种废溶液的处理问题,而不会引起与环境污染有关的麻烦。 本发明的方法包括以下步骤:用活性炭处理废溶液以去除有机杂质; 将溶液与上述金属的粉末,颗粒或薄片混合,以沉淀金属形式的铜值,而不是给出添加的金属的氯化物的水溶液; 并分离铜金属粉末和氯化物溶液。

    • An information processing apparatus comprising a program supplying portion, write signal generator, and a data processor, which includes a microprogram controller, microprogram memory, arithmetic unit, and a selector for selecting in an alternative way an address from the microprogram controller and an address from the program supplying portion and supplying the same to the microprogram memory. In the apparatus, it is adapted such that, in a first (program execution) mode, the address from the microprogram controller is supplied through the selector to the microprogram memory, in a second (reset, or stop) mode, the microprogram controller is supplied with a signal, whereby the same is caused to continuously generate program start addresses, and in a third (program transfer) mode, the address from the program supplying portion is supplied through the selector means to the microprogram memory and, according to a write signal from the write signal generator, the program from the program supplying portion is written in the microprogram memory.When supplying a plurality of different programs from the program supplying portion to the processors operating under the program, such a method can be used to treat the whole of the plurality of different programs as one program and supply this program to the processors at one time of transfer and separately supply an execution start address of one program out of the plurality of different programs to each of said processors.
