Abstract: A liquid mixture obtained by mixing a bolus and an adjusting agent is poured into a tray-shaped container, and during spreading of bolus particles constituting the bolus along the bottom surface, the tray-shaped container is placed in a first inclined state in which the bottom surface is inclined by increasing the height of one edge side in the left-right direction of the tray-shaped container relative to the other edge side thereof, and the liquid mixture in the tray-shaped container is moved toward the other edge side, after which the tray-shaped container is placed in a second inclined state in which the bottom surface is inclined in the reverse direction by reducing the height of one edge side of the tray-shaped container relative to the other edge side thereof, after which the bottom surface is placed in a horizontal state, and the bolus particles are thereby spread.

Abstract: A coherent laser radar system includes a pulsed laser oscillating a pulsed laser beam which is split into two parts by an optical divider. A first part of the two is transmitted as a transmitted beam via a beam splitter. A second part is supplied to a delay line via a coupling optics and others to be delayed by a predetermined time as a local beam, and is incident onto an optical coupler. The received beam from the target is incident onto the optical coupler via a scanning optics and so on. A photodetector carries out the coherent detection of the light beam coupled by the optical coupler. A signal processor computes a target velocity and the like from a signal generated by the detection and converted into a digital signal by an A/D converter. This makes it possible to solve a problem of a conventional system in that the system configuration is complicated and expensive.
