摘要： In a data distributing party, original data is divided into sub-blocks. Each sub-block is encoded according to a predetermined encoding/decoding formula, to divide each sub-block into sub-symbols. In the predetermined encoding/decoding formula, data prior to encoding can be restored by obtaining a predetermined number of data from data posterior to encoding. Each symbol is generated by retrieving sub-symbols from respective sub-blocks and each generated symbol is distributed. In contrast, in a data receiving party, when completing the reception of the symbols not less than a predetermined number necessary for restoring, the sub-symbols are extracted from the respective received symbols in an order of receiving the symbols to restore the sub-blocks posterior to encoding. Each restored sub-block posterior to encoding is decoded according to the above encoding/decoding formula to restore each corresponding sub-block prior to encoding. The restored sub-blocks are then joined to one another to restore the original data.

摘要： A weak-link Josephson junction is of the type employing a thin film of an oxide superconductor, in which a crystal grain boundary produced reflecting an artificial crystal defect is utilized as the weak-link junction. The crystal grain boundary is formed concretely by a method in which atoms of different species are deposited on the predetermined part of the surface of a substrate, the predetermined part of the surface of a substrate is disturbed, or parts of different crystal face orientations are formed at the surface of a substrate, whereupon the superconducting thin film is epitaxially grown on the substrate, or by a method in which the predetermined part of the superconducting thin film, epitaxially grown on a substrate, is diffused with atoms of different species hampering a superconductivity, or the predetermined part of the superconducting thin film is disturbed, whereupon the superconducting thin film is annealed.

摘要： An electron tube cathode has a composite suppression layer structure interposed between the base metal and the electron-emitting material to suppress an interface layer formed through the reaction of the base metal with the electron emissive material. The composite layer structure includes a thin layer of Pt or Re and a layer of oxide of Zr and/or Hf. As a result, the formation of the interface layer is prevented so that the useful life of the electron tube cathode is prolonged.
