  • Publication number: 20220125403
    Abstract: Provided is a technique for improving spatial resolution contrast of an ultrasonic tomogram compared with a method based on a coherence between echo signals. The present invention provides an ultrasonic tomogram generation method including: an estimation step SA100 of estimating noise in echo signals of M channels output from an ultrasonic probe, which receives echoes of ultrasonic waves emitted from M (being a natural number of 2 or more) ultrasonic transducers and outputs an echo signal, and calculating a weight coefficient for emphasizing an echo from a reception focus according to a signal-to-noise ratio in the echo signals of the M channels; and a generation step SA110 of generating a beamformer representing an ultrasonic tomogram from the echo signals of the M channels, using the weight coefficient calculated in the estimation step SA100.

  • Publication number: 20190103756
    Abstract: The charging and discharging control apparatus is an apparatus that controls charging and discharging of a power storage apparatus. The power storage apparatus is connected to an AC power line and is connectable to a specific load without involving the AC power line. The AC power line is connected to a power system, is connected to a direct-current power line through a DC/AC conversion apparatus (PV-PCS), and is connectable to a general load. The charging and discharging control apparatus includes an acquisition unit that acquires information on a direction of a current in the AC power line, and a control unit that supplies electric power to the power storage apparatus when a current is flowing from the AC power line to the power system.

  • Patent number: 10232626
    Abstract: An inkjet printer includes an ejection head that ejects an ink onto a recording medium, a passage in which an ink mist generated by the ejection head flows, a gas-liquid separator that is located in a portion of the passage and separates ink and air from the ink mist, and a blower that is located in the passage and causes the ink mist to be moved away from the ejection head to the gas-liquid separator. A downstream side of the gas-liquid separator is above an upstream side of the gas-liquid separator in a gravitational direction.

  • Patent number: 9969186
    Abstract: A printer includes an ink head, a first heater, a second heater, and a controller. The ink head includes first and second ink heads arrayed along a main scanning direction. The first heater is upstream of the platen in a sub-scanning direction, and heats the recording medium. The second heater is below the platen, and heats the recording medium placed on the platen. The controller includes a heater controller that controls the first and second heaters so that the surface temperature of a first region in which a first ink ejected from a first upstream nozzle array lands becomes higher than the surface temperature of a second region in which a second ink ejected from the second downstream nozzle array lands.
