IPC: G06F17/30
Filed: 2009-04-30
Abstract: <P>PROBLEM TO BE SOLVED: To reduce an index size although the erroneous detection of connection processing may occur in information retrieval.  <P>SOLUTION: A document is read from a document database, and the character string of the document is divided for each word, and the number of pieces of position information showing at which position is each word located when it is counted from the leading is summarized by a preliminarily set numerical value which is equal to or less than fixed length, and the string of position information is mapped to one transposition list, and the transposition list is added to a transposition index storage means. Also, the number of pieces of position information is summarized by using arbitrarily designated division characters instead of fixed length, so that even when words are not connected, those words are prevented from operating just like they are connected.  <P>COPYRIGHT: (C)2011,JPO&INPIT

Title: Motor control method and its apparatus
Inventor: MAEDA TOSHIYUKI
IPC: H02P6/18
Filed: 2009-05-19
Abstract: <P>PROBLEM TO BE SOLVED: To achieve a power saving by putting regenerative power to practical use when a rotational speed variation of a motor is controlled to a periodical load.  <P>SOLUTION: Direct-current power supply is obtained by supplying alternating-current power supply 1 to a converter 2, is smoothed by a smoothing capacitor 3, and is supplied to the motor 5 by being alternating-current power-supplied by an inverter 4. The motor 5 drives a compressor 6 which shows a periodical load variation. Regenerative resistance 7 is connected between output terminals of the converter 2. In the case that a regenerative operation is partially conducted for reducing the rotational speed variation accompanying the periodical load variation, running of power in one rotation average is directed from the inverter 4 to the motor 5, and DC voltage does never continue to rise due to regeneration. An inverter run can be continued without energy consumed by the regenerative resistance 7 by properly selecting capacity of the smoothing capacitor 3 therefor.  <P>COPYRIGHT: (C)2009,JPO&INPIT
