    摘要： A finely structured grooved gate transistor of which the threshold voltage does not decrease in spite of the small size and of which the threshold voltage of the transistor can be adjusted by shape. The shape of a groove corner of the transistor as a semiconductor device is contained in a concentric circle having a radius of curvature r.+-.L/5 (L: channel length) and the radius of curvature r, i.e., the geometric parameter has a relationship with the doping concentration as shown in FIG. 1B. Alternatively, the average (a+b)/2 (geometric parameter) of the sum of the two sides opposite the right angle of a right triangle formed of a straight line in contact with the gate bottom in parallel to the substrate surface of a grooved gate transistor, a perpendicular line to the substrate bottom surface from the source and drain ends at a portion formed with a channel and a straight line in contact with the groove corner has a relationship with the doping concentration as shown in FIG. 1B. The threshold voltage is not reduced even when the channel length is decreased by adjusting the groove shape and the doping concentration.

    摘要： The configuration comprises a carrier equipping an ejection plate on the front for ejecting the bundled-paper sheet material P and equipping a plurality of cutout parts, which are open in their top parts, at a predetermined interval on both the left and right sides; and a drive transmission unit being equipped by a plurality of drive rollers, each of which comprises a plurality of bosses in a predetermined interval on a single circumference around the rotation center thereof, in a predetermined interval on both the left and right sides of the bundled-paper sheet material transport path, wherein a drive force is transmitted by allowing bosses of each drive roller, which rotates by receiving a drive force from a drive source, engage in the respective cutout parts of the carrier sequentially, thereby allowing the carrier travel in the front and back directions of the bundle transport path.
