  • Patent number: 11595562
    Abstract: An autofocus (AF) frame integration unit generates at least two groups, each group including at least one focus detection area based on a comparison between a plurality of focus detection results, the plurality of focus detection results to be obtained corresponding to a specific time. A movement determination unit determines whether an object corresponding to a first group and a second group is moving, based on a focus detection result corresponding to the first group, generated based on a focus detection result corresponding to a first time, and a focus detection result corresponding to the second group, generated based on a focus detection result corresponding to a second time later than the first time.

  • Patent number: 11437881
    Abstract: A motor includes a sheet-metal cover accommodating a stator and a substrate and a wiring assembly electrically connected to the substrate. The cover includes a wiring lead port, which is open to a wall of the cover and communicates with an outside and an inside of the cover. The wiring assembly includes cables connected to the substrate and extending from the inside of the cover to the outside through the wiring lead port, a sleeve with a tubular shape into which the cables are inserted, the sleeve having an elastic modulus smaller than an elastic modulus of a coated portion of the cable, and a binder that bundles the cables through the sleeve. The sleeve is opposed to the wiring lead port from the inside of the cover, and an outer diameter of the sleeve is larger than an inner diameter of the wiring lead port.

  • Patent number: 5071090
    Abstract: An airship having improved controllability which comprises: an axial fluid pathway penetrating through a body of the airship in an axial direction, at least one radial fluid pathway crossing the axial fluid pathway and penetrating through the body in a radial direction, the axial fluid pathway and the radial fluid pathway forming a ventilating-thrusting tube having a rigid framework construction, propulsion means, thrust generating direction of which is adjustable, arranged in a crossing region of the axial fluid pathway and the radial fluid pathway, and a lift balloon arranged beside the ventilating-thrusting tube in such a manner that a gap is formed between the ventilating-thrusting tube and the lift balloon to allow air to flow through. This arrangement lowers a tendency of yawing due to a transverse wind. The airship has a semi-rigid and semi-flexible construction capable of making up for drawbacks of both rigid type and flexible type.
