  • Publication number: 20230068966
    Abstract: A signal generation device includes a memory configured to store instructions and a processor communicatively connected to the memory. The processor is configured to execute the instructions to function as a signal generation unit to generate a sound signal based on key operation data associated with a key operation and a decay control unit to control a decay speed of the sound signal based on pedal operation data. The decay control unit is configured to control the decay speed to a first speed in a case where the pedal operation position is in a first range, and the decay control unit is configured to control the decay speed to a second speed in a case where the pedal operation position is in a second range. A first boundary position between the first and the second ranges is determined based on control information obtained by the key operation.

  • Patent number: 11291949
    Abstract: A carbon dioxide separation recovery method includes: bringing a particulate carbon dioxide adsorbent and a treatment target gas containing carbon dioxide into contact with each other to make the carbon dioxide adsorbent adsorb the carbon dioxide contained in the treatment target gas; and bringing the carbon dioxide adsorbent which has adsorbed the carbon dioxide and superheated steam into contact with each other to desorb the carbon dioxide from the carbon dioxide adsorbent and thereby regenerate the carbon dioxide adsorbent, and recovering the desorbed carbon dioxide. A saturation temperature of the superheated steam which is brought into contact with the carbon dioxide adsorbent is not more than a temperature of the carbon dioxide adsorbent which contacts the superheated steam. The regenerated carbon dioxide adsorbent is utilized for adsorption of the carbon dioxide again without being subjected to a drying step.
