  • Patent number: 11962972
    Abstract: To enhance a sound image localization effect and to ensure a good viewing state in which an image or video and audio have a sense of unity. Provided is a display in which an image is displayed in a display surface, a rear cover disposed on a rear side of the display, a first speaker disposed between the display and the rear cover, and a second speaker disposed between the display and the rear cover and positioned higher than the first speaker. The second speaker outputs audio according to operation of a piezoelectric element, and has a higher audio output band than the first speaker. This enables a user to feel as if the audio is being output from the display being viewed, which enhances the sound image localization effect and ensures a good viewing state in which an image or video and audio have a sense of unity.

  • Publication number: 20220286069
    Abstract: To provide a generator control device that, even when communication with an external control device is interrupted, evaluates independently, and can increase an amount of power generated so that a drop in DC voltage can be restricted preemptively, while restricting a fluctuation of rotational speed. A generator control device determines that a voltage drop prediction time control is executed when it is predicted that a drop of the DC voltage will be large; generates a rectangular pulse wave such that a duty ratio increases gradually during the excitation time when determining that the excitation control rotational speed condition was fulfilled, and the voltage drop prediction time control is executed; and changes the duty ratio so that the detected value of the DC voltage nears the increased target voltage when determining that the excitation control rotational speed condition was not fulfilled, and the voltage drop prediction time control is executed.

  • Patent number: 10924045
    Abstract: Power generation control devices (4) of respective power generators (1) transmit conduction rates of field coils (101) of the respective power generators (1) to an external control device (5), while the external control device (5) obtains an average value of the conduction rates, obtains a field duty limiting command value for limiting the conduction rate of the field coil (101) determined by the power generation control device (4) based on the average value, and transmits the field duty limiting command value to the power generation control device (4). With this operation, the power generation control device (4) limits power generation amounts of the respective power generators (1) based on the command value, to thereby equalize the power generation amounts of the respective power generators (1).
