Filed: 1987-02-23
Abstract: PURPOSE:To retrieve plural retrieval character-strings by an operation of once, by providing one summary with respect to plural character-strings to be retrieved, execut ing a lump retrieval until the end of a sentence, and storing an appearance frequency and an appearance position in a document in accordance with the summary of its retrieval character-string, when the character-strings to be retrieved which coincide each other are detected in the document. CONSTITUTION:In a document storage part 6, a character code related to a document which is being generated and array information of a character are stored, and in a retrieval character-string summary storage part 7, plural retrieval character-strings to be retrieved thereafter are stored. Also, a retrieval processing part 9 compares a retrieval character-string stored in the retrieval character-string storage part 7, and a character-string to be retrieved stored in the document storage part 6, and takes its coincidence. A retrieval result storage part 10 stores a result of retrieval obtained by the retrieval processing part 9. That is, when the character-string to be retrieved which coincides with the retrieval character-string is detected at the time of executing the retrieval processing, an appearance frequency of its retrieval character-string and a position in a document which is appeared are stored. In such a way, the facilitation of a substitute by the re-retrieval or the facilitation for generat ing an index is contrived.

Title: Rectifier
Inventor: KURITA SHIGEO
IPC: H02M7/06
Filed: 1988-02-24
Abstract: PURPOSE:To simplify the structure of a rectifier by employing as the rectifier oxide superconductor at a temperature near its transition temperature. CONSTITUTION:A circuit associated with three oxide superconductors 2-4 in an AC power source 1 is formed. The superconductors 2-4 are always cooled to its transition temperature or lower, but only the superconductor 3 is set to the transition temperature or higher. Thus, when a current flows as designated by a solid line, the superconductors 2, 4 are heated to become the transition temperature or higher, thereby having a large resistance value. The superconductor 3 is cooled to the transition temperature or lower during this period, and a current flows as designated by a broken line when the direction of the current is then changed. As a result, an AC can be converted to a DC.
