Abstract: An ultrasound image apparatus irradiates a bonded wafer in which two or more wafers are bonded with an ultrasonic wave to generate an image of the bonded surface between the wafers. An ultrasonic probe irradiates the bonded wafer with the ultrasonic wave on a lower side of the bonded wafer.

Abstract: An automatic analysis device improves the uniformity of a mixed liquid by noise agitation by a dispensing mechanism. The dispensing mechanism agitates a mixed liquid by suctioning the mixed liquid into a reaction vessel by a nozzle and then re-discharging the suctioned mixed liquid into the reaction vessel. When the mixed liquid is re-discharged into the reaction vessel, the nozzle is moved upward at a speed higher than a speed at which the liquid surface of the mixed liquid rises due to the re-discharging of the mixed liquid from the nozzle during a first period and lowers the speed of moving the nozzle upward than the speed during the first period while maintaining or reducing the speed at which the liquid surface of the mixed liquid rises due to re-discharging of the mixed liquid from the nozzle during a second period following the first period.
