Abstract: The present invention provides a data input/output control device integrating a one-chip microcomputer together with a data transfer device and a processor, the data transfer device being constructed to transmit to and receive from an external apparatus serial data and the processor processing data inputted to the data transfer device and transmitting the processed data to the data transfer device to be further transmitted to the external apparatus, the date input/output control device characterized in that a clock of the data input/output control device for an operation thereof is a transfer clock utilized by the external apparatus and the transfer clock is slower than a clock for the processor.

Abstract: A process and an apparatus for producing an alloy containing terbium (Tb) and/or gadolinium (Gd). The process includes the steps of: (a) preparing a bath of molten electrolyte which consists essentially of 20-95% by weight of TbF.sub.3 and/or GdF.sub.3, 5-80% of LiF, up to 40% of BaF.sub.2 and up to 20% of CaF.sub.2 ; (b) reducing the TbF.sub.3 and/or GdF.sub.3 in the bath, with carbon anode and with cathode made of a metal such as iron or cobalt, so as to electrodeposit Tb and/or Gd on the cathode, and alloying the electrodeposited Tb and/or Gd with metal of the cathode so as to produce the alloy containing Tb and/or Gd in a liquid state on the cathode; (c) adding the TbF.sub.3 and/or GdF.sub.3 to the bath so as to maintain the composition of the bath, for compensating for consumption of the TbF.sub.3 and/or GdF.sub.

Abstract: A process and an apparatus for producing a dysprosium-iron alloy or a neodymium-dysprosium-iron alloy by electrolytic reduction of dysprosium fluoride or neodymium fluoride and dysprosium fluoride in a bath of molten electrolyte, consisting essentially of 20-95% by weight of dysprosium fluoride or a mixture of neodymium fluoride and dysprosium fluoride, 5-80% by weight of lithium fluoride, up to 40% by weight or barium fluoride and up to 20% by weight of calcium fluoride, conducted between one or more iron cathode and one or more carbon anode.
