Abstract: TSV devices with p-n junctions that are planar have superior performance in breakdown and current handling. Junction diode assembly formed in enclosed trenches occupies less chip area compared with junction-isolation diode assembly in the known art. Diode assembly fabricated with trenches formed after the junction formation reduces fabrication cost and masking steps increase process flexibility and enable asymmetrical TSV and uni-directional TSV functions.

Abstract: A clamp 10 for holding two elongate members 23a, 23b so that they extend at a preset angle from each other, comprising: two clamp portions 12, 14 each having co-operating engaging surfaces 16a, 16b, each clamp portion having an axial bore 18a, 18b extending perpendicularly to the engaging surfaces and a receiving portion for holding one of the elongate members; a stem or rod 19, passing through the bore of the clamp portions and attached at one end to a lever or handle 20 for rotating the stem in the bore, and a cam acting between the stem and at least one of the clamp portions so that the clamp portions can be moved from a position in which the engaging surfaces are not engaged to a position in which the engaging surfaces co-operatively engage by rotating the lever by approximately 90°.

Abstract: A light reflector includes a plurality of opaque, generally triangular panels connected together to form a three dimensional geometric figure surrounding an inside space. Each panel has a reflective surface facing the inside space and each corner of each of the panels is adjacent a corner of an adjacent panel. The panels are spaced apart from each other by rectangular, open areas. An artifical light source is placed inside the inside space. The reflective surfaces relect light from the artificial light source and direct reflected light toward the rectangular open areas. Plants are situated adjacent the rectangular open areas and receive light emanating therefrom.
