  • Patent number: 10803103
    Abstract: [Object] To provide a system for automatically and reliably collecting information belonging to a given category, and matching the information appropriately in a timely manner. [Solution] A text classifying device 30 analyzes dependency of collected texts by a morpheme analyzing unit 52 and a dependency analyzing unit 54. A problem report collecting unit 64 specifies a core consisting of noun+predicate in a text based on dependency relation of the text, and using a combination of noun classification (trouble/non-trouble) and predicate classification (excitatory/inhibitory), classifies the text to a problem report or the rest, by a method referred to as core-based matrix. Support information collecting device 66 and request message collecting device 68 collect support information and request messages in the similar manner.

  • Patent number: 10536074
    Abstract: A power-factor correcting converter includes: a series circuit including a first higher-potential switch and a first lower-potential switch connected in series to each other; and another series circuit including a second higher-potential switch and a second lower-potential switch connected in series to each other. In a positive phase period of the input AC voltage, a control circuit turns off the second higher-potential switch, turns on the second lower-potential switch, and alternately turns on and off the first lower-potential switch as a master switch and the first higher-potential switch as a slave switch. In a negative phase period of the input AC voltage, the control circuit reverses the on/off operation and the master/slave relationship, and turns on and off only the master switch and turns off the slave switch when the absolute value of the input AC voltage is smaller than or equal to a predetermined value.
