The reinforcing flange includes a circumferential portion formed upright along the circumference and a notch portion formed upright near the orientation notch, and a width of the circumferential portion as viewed parallel to a major surface of the wafer is smaller than a depth of the orientation notch as viewed parallel to the major surface. In one embodiment, an automated dispensing device dispenser a predetermined portion of food from a bulk storage container or food dispensing magazine. Other rollers are formed from a relatively soft material and are convex to provide a light frictional resistance to movement of the carriage along the tracks that inhibits drift, over-travel and other inadvertent movement of the carriage, while reducing noise. A multi-cycle modulator circuit is coupled to the output of the comparator. The invention relates to the seeds of soybean cultivar 0487681, to the plants of soybean 0487681 and to methods for producing a soybean plant produced by crossing the cultivar 0487681 with itself or another soybean variety.
