Abstract: A commercially mass-produced, integrated circuit including: a solid substrate of one conductivity type; at least one solid material pocket of a different conductivity type having a side surface and positioned on a selected top surface of the substrate to thereby form a signal-translating, electronic rectifying barrier between the at least one solid material pocket and the selected top surface of the substrate; and a solid state material region adjoining the substrate, the electronic rectifying barrier, and the side surface of the at least one solid material pocket; wherein next to the electronic rectifying barrier the solid state material region has a lateral dimensional accuracy of better than a few hundred atomic layers.

Abstract: An automatic card cutter capable of continuously cutting paper material of various amounts and sizes comprises a feeding unit, a transport unit, a transverse cutting unit, a longitudinal cutting unit, a waste material collector, a card collector and a shell body. The feeding unit has two spacing-adjustable side plates. Each of the side plates is provided with a flexible plate, an impression wheel against the flexible plate and drive set for driving the impression wheel, whereby paper materials of various amounts can be fed into the cutter smoothly. The longitudinal cutting unit comprises a plurality of slidable wheel knife sets, so that the cutting width of the paper material can be easily set.
