  • Publication number: 20200166884
    Abstract: A first supply mode is a mode for supplying power so that printing can be performed by a printing unit, and more power is supplied in the first supply mode than in the second supply mode or the third supply mode. More power is supplied in the second supply mode than in the third supply mode. In the specified period, the power supply circuit switches from the power supply in the first supply mode to the power supply in the second supply mode when a first transition condition is satisfied. The power supply circuit maintains the second supply mode without performing switching from the power supply in the second supply mode to the power supply in the third supply mode.

  • Patent number: 7111471
    Abstract: The present invention aims to prevent the occurrence of liquid compression at the second rotary compression element before it happens while improving the compression efficiency with an intermediate cooling circuit in a refrigerant cycle apparatus which comprises an internal high-pressure type multi-stage compression compressor, and the invention is summarized in that the apparatus comprises an intermediate cooling circuit which allows refrigerant discharged from the first rotary compression element of a compressor to dissipate heat, where a microcomputer performs control on the number of revolutions of the compressor to maintain the temperature/pressure of refrigerant so that the refrigerant does not condense at the output of the intermediate cooling circuit, where such a control is done in response to outputs from an outside-air temperature sensor, a refrigerant temperature sensor, and a signal from a controlling apparatus of a refrigerating apparatus body.
