  • Publication number: 20200096490
    Abstract: A method for analyzing a gas includes: allowing a sample gas to be adsorbed by each of a plurality of adsorbents (70) respectively having compositions that are different from each other; allowing the sample gas to be desorbed individually from the adsorbents (70) while detecting individually the sample gas desorbed from each of the adsorbents (70) so as to acquire desorption profiles of the sample gas that are respectively unique to the adsorbents (70); and identifying the sample gas by using a group of the desorption profiles. The acquiring of the desorption profiles is carried out by detecting, individually and over time, the sample gas desorbed from each of the adsorbents (70). Each of the desorption profiles is, for example, an overtime data created from a detection signal reflecting a quantity of the sample gas.

  • Publication number: 20200033248
    Abstract: In a method for analyzing samples involving the use of a device for analyzing samples, the device for analyzing samples includes at least a movement part through which a sample moves, and a measurement unit that is formed in a middle of the movement part and that measures a value of an ion current when the sample passes through the movement part. The analysis method includes at least a measurement step for measuring the value of the ion current when the sample passes through the movement part, and a determination step for determining a change over time in a quantity of ions from the value of the ion current measured in the measurement step. The quantity of ions includes a quantity of ions that have leaked from the sample during movement of the sample through the movement part.

  • Patent number: 10328928
    Abstract: There is provided a hybrid vehicle comprising a mode selection device configured to select one drive mode among a plurality of drive modes according to a user's operation. The plurality of drive modes include a first drive mode in which the hybrid vehicle is driven with power from a motor with stopping rotation of an engine and a second drive mode in which the hybrid vehicle is driven with rotation of the engine. On satisfaction of filter regeneration conditions that an accumulated amount of particulate matter accumulated on a filter is equal to or greater than a predetermined accumulated amount and that a temperature of the filter is equal to or higher than a predetermined temperature, the hybrid vehicle is driven in the second drive mode even when the first drive mode is selected by the mode selection device.
