  • Publication number: 20240067258
    Abstract: A rotating machine control device comprises: a first inverter that applies an alternating-current voltage to three-phase windings of a first system included in a rotating machine, based on a first direct-current voltage that has been output from a direct-current power supply of the first system; a second inverter that applies an alternating-current voltage to three-phase windings of a second system included in the rotating machine, based on a second direct-current voltage that has been output from a direct-current power supply of the second system; a first controller; and a second controller, in that the first controller and the second controller each limit an own system voltage command related to a voltage to be applied to the three-phase windings of an own system by use of a direct-current voltage of an other system, in a case where a direct-current voltage of the own system is higher than the direct-current voltage of the other system, and also generate a value obtained by normalizing the own system voltag

  • Patent number: 11356615
    Abstract: A camera device includes a first IR illuminator that is configured to irradiate a first irradiation range in a capturing area with first IR light, a second IR illuminator that is configured to irradiate a second irradiation range narrower than the first irradiation range in the capturing area with second IR light, and a controller that is configured to obtain a zoom magnification of the lens and controls the irradiation of the first IR light and the second IR light in a case where the zoom magnification is equal to a predetermined zoom magnification. The controller changes a supplied current of the first IR illuminator for the irradiation of the first IR light over a first predetermined time period, and changes a supplied current of the second IR illuminator for the irradiation of the second IR light over a second predetermined time period.

  • Patent number: 11025839
    Abstract: There is provided a camera apparatus including: a capturing unit that includes a lens to which light, from a capturing area including IR light and visible light is incident, and that performs capturing based on the light; an IR lighting unit that irradiates the capturing area with IR light; and a controller that generates an instruction to change a focal position of the lens and an instruction to adjust a quantity of the IR light, in which the controller calculates an IR light ratio which indicates a ratio of the quantity of the IR light to the light included in a captured image of the capturing area, and selects and performs any one of a first focusing processing to change the focal position of the lens corresponding to the IR light, a second focusing processing to change the focal position of the lens corresponding to the visible light, and an IR light quantity adjustment determination processing to determine whether or not to adjust the quantity of the IR light, based on the IR light ratio.

  • Patent number: 7012708
    Abstract: An IFAX on a transmitting end gains access to an ISP on the transmitting end by dialup. The IFAX on the transmitting end transmits mail transmission notice to an IFAX on a receiving end via a PSTN after transmitting e-mail to the ISP on the transmitting end. Thereafter, the IFAX on the receiving end gains access to an ISP on the receiving end by dialup in accordance with mail transmission notice and receives e-mail stored in its own postbox. The mail transmission notice is performed using a facsimile communication protocol. The mail transmission notice includes at least one of transmission finished notice information, sent data information, and receiving information. This eliminates the unavailing mail check connection and reduces access charge at a dialup IFAX of the Internet facsimile.

  • Patent number: 6339684
    Abstract: The recording apparatus of the present invention acquires time data from a clock built in the main body of the apparatus, and generates first calculation data by calculating the time data with a predetermined calculation method. Meanwhile, in the cartridge attached to the main body, the time data is acquired from the main body, and second calculation data is generated by calculating the time data with the same calculation method as the above-mentioned predetermined calculation method. As a result of comparing the first calculation data to the second calculation data, it is judged that the attached cartridge is proper when both of the data match, and it is judged that the attached cartridge is not proper when both of the data do not match. It is thereby possible to judge whether or not the cartridge attached to the main body is proper.
