  • Publication number: 20200295687
    Abstract: According to one embodiment, a driving device includes a voltage controller, a parameter setter, and a phase adjuster. The voltage controller causes an electric power converter to apply a drive voltage to the electric motor, the electric power converter converting input electric power to A/C electric power having desired voltage and frequency and supplying the converted electric power to an electric motor. The parameter setter sets at least one of a rotation speed of the electric motor and a parameter related to the rotation speed as speed information. The phase adjuster adjusts a phase of the drive voltage in such a manner that an index calculated based on a current flowing in the electric motor and the speed information set in the parameter setter becomes smaller.

  • Patent number: 9203987
    Abstract: This invention has as its object to allow an authentication process that avoids unnecessary information from being stored in a digital camera irrespective of whether or not a digital camera connected to the printer has a direct print function. To this end, in this invention, in an early stage of connection between a digital camera DSC and PD printer, the PD printer side requests an object which contains a keyword as authentication information of those which are stored and held by the DSC (S29). As a result, after it is determined the returned information contains authentication information, the printer notifies the DSC of its own authentication information (S33).
