  • Patent number: 11955600
    Abstract: A solid-state battery is provided that allows the exterior can to be sufficiently crimped onto the seal can without leading to improper crimping, thus preventing entry of water from the outside. The solid-state battery 1 includes an exterior can 2, a seal can 3, facing the exterior can 2 and a power generation element 4 contained in the space between the exterior can 2 and seal can 3. The seal can 3 includes a flat portion 31 and a peripheral wall 32 that are contiguous to each other with a curved-surface portion 33 provided therebetween. A first clearance g1 is defined between the upper edge of the outer peripheral surface of the power generation element 4 and the border 10 between the inner surface of the flat portion 31 and the inner surface of the curved-surface portion 33, the first clearance having a radial dimension not larger than 2.0 mm at a position where its dimension is at its largest.

  • Patent number: 11602333
    Abstract: An ultrasound diagnostic apparatus includes: a transmitter; a receiver; a Doppler processor that detects a Doppler shift frequency resulting from a blood flow in a subject, based on a reception signal corresponding to a reflected wave from a sample gate position in the subject; and a velocity scale adjuster that adjusts a velocity scale determining a pulse repetition frequency, based on a Doppler waveform corresponding to the Doppler shift frequency during an observation target period. In a case where a recommendation value of the velocity scale calculated based on the Doppler waveform is larger than a critical value of the velocity scale at which a measurement state calculated based on the sample gate position transitions from a non-high-pulse-repetition-frequency state to a high-pulse-repetition-frequency state, the velocity scale adjuster sets the critical value as the velocity scale to be used in measurement.

  • Patent number: 11576656
    Abstract: An ultrasound diagnostic device generates a frame reception signal by compounding sub-frame reception signals acquired from a subject body through an ultrasound probe. The sub-frame reception signals are generated through sub-scans composing an ultrasound scan. Between the sub-scans, a range in the scanned subject body differs due to a different ultrasound beam steering angle used. The diagnostic device includes a control circuit with a reception signal acquirer acquiring sub-frame reception signals, and a map creator creating sub-frame enhancement maps corresponding to the sub-frame reception signals, the maps created by calculating, for a pixel region reception signal, an enhancement amount according to a characteristic value calculated based on the pixel region reception signal.

    Abstract: The present invention provides a technique to accurately recognize a position of a vehicle even in a vicinity of a branch road or a junction road, neither of which is included in map data. The present invention provides a vehicle control device. When a vehicle is traveling on a road that is not described in map data, the vehicle control device is configured to determine whether or not the vehicle is traveling on a junction road or a branch road, based on a positional relationship between a position of the vehicle and a starting point of the junction road or a starting point of the branch road.

  • Patent number: 11484295
    Abstract: An ultrasound diagnostic apparatus transmits ultrasound toward a subject by driving an ultrasound probe in which multiple transducers are arranged in an array, receives a reception signal that is based on waves reflected within the subject from the ultrasound probe, and generates an ultrasound image. The ultrasound diagnostic apparatus includes: a scan control section that sets scan conditions so that trapezoidal scanning is performed by the ultrasound probe; and a transmission section that controls driving of the ultrasound probe based on the scan conditions. The scan control section sets the scan conditions so that the inter-acoustic line angles in or around the center of the ultrasound probe are smaller than the inter-acoustic line angles near the edges when viewed along the scan direction.
