  • Patent number: 11951383
    Abstract: Using output of an inertial sensor, whether an operation device is in a swing state of being swung is determined. Whether the operation device is rotated in a first direction about a predetermined axis of the inertial sensor or a second direction opposite to the first direction, is determined. Whether the operation device is swung in an upward direction or a downward direction is determined. First processing is executed in at least either a case where the operation device is rotated in the first direction about the predetermined axis or a case where the operation device is swung in the upward direction, during the swing state. Second processing is executed in at least either a case where the operation device is rotated in the second direction about the predetermined axis or a case where the operation device is swung in the downward direction, during the swing state.

  • Publication number: 20230249068
    Abstract: During execution of a game, first-type processing is executed if it is determined that an input device has been moved in a first direction at a timing when a predetermined condition is satisfied during execution of the game, on the basis of operation data including at least data based on an output of an inertial sensor. In a case where, on the basis of the operation data, it is determined that the input device has been moved in a second direction at a timing when the predetermined condition is satisfied, if it is further determined that the input device has been moved in the first direction during a predetermined suspension period, the first-type processing is executed. If it is determined that the input device has not been moved in the first direction during the predetermined suspension period, second-type processing is executed after the predetermined suspension period has elapsed.

  • Publication number: 20230138154
    Abstract: An electronic component includes conductor layers and insulating resin layers which are alternately stacked on a substrate. One of the insulating resin layers positioned in the lowermost layer is smaller in thickness than the insulating resin layers, and the insulating resin layers are smaller in thermal expansion coefficient than the one of the insulating resin layers. Thus, an element that requires high processing accuracy, such as a capacitor, can be embedded in the insulating resin layer positioned in the lowermost layer and having a small thickness, and an element that requires a sufficient conductor thickness, such as an inductor, can be embedded in the insulating resin layers having a large thickness. In addition, since the insulating resin layers each have a small thermal expansion coefficient, the occurrence of warpage and peeling can be suppressed.

  • Publication number: 20230005667
    Abstract: An electronic component includes: a conductive pattern provided on the main surface of a substrate and constituting a lower electrode; a dielectric film that covers top and side surfaces of the conductive pattern; and a conductive pattern stacked on the top surface of the conductive pattern through the dielectric film and constituting an upper electrode. A part of the dielectric film that is parallel to the main surface of the substrate is removed at least partly. Partially removing a part of the dielectric film that is parallel to the main surface of the substrate allows stress relaxation. This prevents peeling at the interface between the lower electrode and the dielectric film.
