Abstract: An ultrasound diagnostic apparatus includes the following. A deflection controller generates delay time information to make phases of reception signals input to channels uniform according to a deflection angle. A channel selector selects a channel in which the reception signal is turned on or off so that the phases of the reception signals input to channels are different and which generates channel selection information. A reception delay interrupter provides the delay amount to the reception signal and which turns on or off the reception signal. An adder adds the plurality of reception signals which are provided with the delay amount and turned on.

Abstract: An assembling apparatus assembles beads different in particle size from each other. The assembling apparatus includes a substrate and a photothermal light source. The substrate is constructed to be able to hold a sample in which the beads are dispersed. The photothermal light source irradiates the substrate or the sample with laser beams to thereby produce a temperature difference in the sample.
