  • Publication number: 20230400507
    Abstract: A sensor acquires an operating condition of a target circuit. When an operating condition changes, a control circuit corrects an operating time of the target circuit based on a changed operating condition to obtain a corrected operating time, and calculates performance degradation information of the target circuit by using the changed operating condition and the corrected operating time.

  • Publication number: 20150030693
    Abstract: An object of the present invention is to provide an antitumor aqueous solution and an anticancer agent, both of which can kill cancer cells while having virtually no effects on normal cells, and to provide methods for producing the antitumor aqueous solution and the anticancer agent. The method of the invention for producing an antitumor aqueous solution for killing cancer cells includes an aqueous solution preparation step of preparing an aqueous solution through addition, to water, of a solute containing at least one of disodium hydrogen phosphate (Na2HPO4), sodium hydrogen carbonate (NaHCO3), L-glutamine, L-histidine, and L-tyrosine disodium dihydrate (L-tyrosine.2Na.2H2O); and a plasma irradiation step of irradiating the aqueous solution with atmospheric pressure plasma generated in a plasma generation region by means of a plasma generator.

  • Publication number: 20140008326
    Abstract: A plasma generation device has a microwave generation device which generates microwave, a waveguide tube having hollow interior and connected to the microwave device such that the tube has longitudinal direction in transmission direction of microwave and rectangular cross section in direction orthogonal to the transmission direction, a phase-shifting device which cyclically shifts phase of standing wave generated in the tube by microwave, and a gas supply device which supplies processing gas into the tube. The tube has antenna portion having one or more slot holes which release plasma generated by microwave to the outside, the slot hole is formed on wall forming short or long side of the antenna portion, and the tube plasmatizes the gas in atmospheric pressure state supplied into the tube by the microwave in the slot hole and releases the plasma to the outside from the slot hole.

  • Patent number: 8486225
    Abstract: An inventive method includes the steps of: loading a fiber product in an appropriate form into a treatment vessel; wetting the fiber product; forcibly circulating an ozone-containing liquid in contact with the wetted fiber product to thereby bleach the fiber product; and forcibly circulating an ozone decomposing chemical agent liquid in contact with the ozone-treated fiber product to decompose ozone. This method ensures efficient bleaching of the fiber product with the ozone. Further, the method is advantageous in that the resulting bleached fiber product is less liable to be yellowed over time.

  • Patent number: 4653931
    Abstract: An electronic timepiece including timekeeping circuitry and a primary power source for converting externally applied energy to electrical energy for powering the timekeeping circuitry. The electronic timepiece also includes a secondary power source for storing energy from the primary power source and powering the timekeeping circuitry. A power controller, coupled to the timekeeping circuitry, primary power source and secondary power source controls the source of power of the timekeeping means so that upon the application of external energy to the primary power source, when the timepiece is not operating in the secondary power source and cannot power the timekeeping circuitry the timepiece begins operating substantially simultaneously.
