Abstract: An unmanned drifting substance monitoring buoy (10) is thrown into a water area where a drifting substance is present, thereby tracking and monitoring the drifting substance. The unmanned drifting substance monitoring buoy (10) detects, by a detecting section, a relative location of the drifting substance on the water surface with respect to the unmanned drifting substance monitoring buoy (10), and measures, by a measuring section, directions and strengths of a wind and a tidal current. Then, the unmanned drifting substance monitoring buoy (10) tracks the drifting substance by adjusting, based on the relative location of the drifting substance detected by the detecting section and on the directions and the strengths of the wind and the tidal current measured by the measuring section, a surface area and a direction of a sail (13) by an adjusting section.

Abstract: A recording material processing apparatus includes: a stacker stacking recording materials to form a bundle; a pressing member including blade sections arranged at intervals to press portions of the bundle, where folds are to be formed, to move the portions in a recording material transport direction; a pair of first fold-forming rolls, each of which includes plural rolls arranged at intervals to enter between the blade sections when the blade sections press the portions, the pair of first fold-forming rolls forming the folds at intervals by nipping the portions pressed by the blade sections; and a pair of second fold-forming rolls, each of which includes plural rolls arranged at intervals to correspond to the blade sections, the pair of second fold-forming rolls further forming the folds on the bundle by nipping portions of the bundle, which exist between the folds formed by the pair of first fold-forming rolls.
