Abstract: Scrap bars of extruded goods are reclaimed as billets for extrusion. An external force is applied to an aggregate of scraps, in which the scraps are piled in the form of a bundle having a predetermined length, so as to reduce its size in directions perpendicular to the longitudinal axes of the scrap bars, thereby forming a billet. The extruded goods produced from the billet have almost no pores and are not inferior to those produced from cast billets.

The flat member is disposed parallel to the enclosure opening and spaced from the enclosure by the lead. The flat member is substantially coextensive with the enclosure opening.

Abstract: The invention relates to a semiconductor component element, in particular a Schottky field-effect transistor with a low series resistance, as well as a process for the production thereof.By means of a novel masking technique, it is possible for the channel region to be implanted as well as the source and drain regions, in a single implantation step. Only one photomask is necessary. By a novel masking arrangement, only a small fraction of the radiated ions get through to the region of the substrate where the channel is to be formed. This enables the formation of a Schottky contact where the channel will be formed. The source and drain regions are formed by allowing a much higher portion of the ions to reach such regions. This allows ohmic contacts to be formed on the source and drain. Thus, in the implantation of the dopant particles, regions are formed with different layer resistances in the semiconductor substrate.

Abstract: Excess signal charge generated in response to optical overload of a charge-coupled sensing region is removed from that region by an antiblooming drain implanted in the substrate of the sensing array. The antiblooming drain is separated from the row of sensing regions by a potential barrier produced by a gate electrode associated with the drain. In fabricating the charge-coupled optical imager, the antiblooming drain is self-aligned with the antiblooming gate electrodes by first providing a pair of spaced-apart antiblooming gate electrodes and implanting the drain region into the substrate using the gate electrodes as a mask.

Abstract: Paper containing three module staffs of contiguous, distinctly shaded bands of equal width are printed with non-photographically reproducible ink on a planar sheet. The bands of each module are spaced from a similar module by a band of non-color and an uncolored area is provided about the periphery of the sheet.
