  • 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.

  • 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.

  • Patent number: 8638842
    Abstract: Provided is an equalization device which receives a signal transmitted from a transmission side of the signal as an input signal, and equalizes the deterioration of a wave shape of the received input signal, wherein a bit value indicated by the input signal is judged in accordance with a clock on the basis of the wave shape of the input signal. From judged signals which result from the judgment and which are composed of a plurality of bits, a two-bit transition signal is detected so that the two-bit transition signal has two adjacent bit values having the same value, and bit values located before and after the two adjacent bit values are different from the bit value of the two adjacent bit values, and the phase of the clock is synchronized with the phase of the detected two-bit transition signal.
