摘要： A process for preparing compound metal oxides, a superconductive compound oxides for instance, is disclosed. The process comprises preparing an aqueous solution containing a predetermined content ratio of chloride, nitrate or acetate of a rare earth metal, an alkaline earth metal and copper, slightly basifying the solution to form hydroxides of the rare earth metal and copper and then introducing carbon dioxide to form carbonate of the alkaline earth metal, collecting the thus formed mixed precipitate of hydroxides and carbonate and firing it.

摘要： A process for preparing compound metal oxides, superconductive compound oxides, is disclosed. The process comprises preparing an aqueous solution containing a predetermined content ratio of chloride, nitrate or acetate of a rare earth metal, an alkaline earth metal and copper, said content ration corresponding to the composition of the object compound metal oxide, adjusting the pH of the solution to 1.5-2.0, adding oxalic acid in an amount such that the concentration of the residual oxalic acid becomes 0.05 M/l-0.1 M/l, collecting the thus formed precipitate and firing it.

摘要： A position detector has first and second timing disks, each having at least one light-transmissive portion.The second timing disk is rotated at a predetermined speed ratio with respect to the first timing disk. A timing sensor is disposed in close proximity to the outer circumference of the first and second timing disks to provide a timing signal when both the light-transmissive portions of the first and second timing disks rotating at predetermined speeds simultaneously pass by the position of the timing sensor.

摘要： A printing apparatus includes a type drum the outer circumferential surface of which has a first set of type including a plurality of type faces arranged in a counter-clockwise spiral and a second set of type including a plurality of type faces arranged in a clockwise spiral. The type drum is both reciprocated and rotated in synchronous fashion by cooperation between reciprocating and rotating drive means so that the sets of type disposed on the type drum pass the positions of a plurality of printing hammers confronting the drum and adapted to perform printing by striking the type faces on the drum through an inked ribbon and recording medium.
