  • Publication number: 20220249062
    Abstract: An image having high resolution in the short axis direction is obtained with a simple configuration. A first transmit aperture, and a second transmit aperture whose aperture size in the short axis direction is larger than the first transmit aperture, are sequentially set in a probe where transducers are arranged in each of the long axis direction and the short axis direction, and the first transmission beam and the second transmission beam are transmitted therefrom respectively. These transmissions generate the first received beam signal and the second received beam signal which are weighted in the depth direction and synthesized. In the first region with a shallow depth, the weight of the first received beam signal is increased, whereas in the second region deeper than the first region, the weight of the second received beam signal is increased.

  • Publication number: 20210270180
    Abstract: A thermostat is provided at a connection portion between a cooling water supply passage and a bypass passage. When the temperature of the cooling water lies in a low temperature range lower than a first reference temperature, the thermostat allows introduction of the cooling water from the cooling water discharge passage into the cooling water supply passage via the bypass passage and also prevents introduction of the cooling water from the radiator into the engine via the cooling water supply passage. When the temperature of the cooling water lies in a high temperature range equal to or higher than a second reference temperature which is higher than the first reference temperature, the thermostat allows introduction of the cooling water from the radiator into the engine via the cooling water supply passage and also prevents introduction of the cooling water from the cooling water discharge passage into the cooling water supply passage via the bypass passage.

  • Patent number: 10980559
    Abstract: In a treatment instrument, one of a pair of jaws is supported by a supporter while being pivot able around the supporter with respect to the supporter. A drive member moves along a longitudinal axis so that the pair of the jaws are closed with respect to each other, thereby applying an axial force onto an elongated member from the drive member by way of the one of the jaws and the supporter in a direction along the longitudinal axis. A contact surface of the elongated member abuts on a housing when the elongated member moves with respect to the housing under the axial force, thereby suppressing rotation of the elongated member around the longitudinal axis with respect to the housing.
