Filter tube making
Patent 8,142,598
A hollow filter tube is produced with a longitudinal seam and a fixed diameter. In the formation of the hollow tube glue is applied along a longitudinal side edge portion of an endless strip, and the strip is then formed into a tubular shape with an unglued longitudinal edge portion tucked directly under and against the glued side edge portion. The hollow tube is then heated to drive moisture from the glue and size and shape the hollow tube. Ultimately the formed hollow tube is cut into specific lengths.[private]

Castellated gate MOSFET tetrode capable of fully-depleted operation
Patent 8,138,544
A castellated-gate MOSFET tetrode device capable of fully depleted operation is disclosed. The device includes a semiconductor substrate region having an upper portion with a top surface and a lower portion with a bottom surface. A source region and a drain region are formed in the semiconductor substrate region, with adjoined primary and secondary channel-forming regions also disposed therein between the source and drain regions, thereby forming an integrated cascade structure. Trench isolation insulator islands, having upper and lower surfaces, surround the source and drain regions as well as the channel-forming regions. Both the primary and secondary channel-forming regions include pluralities of thin, spaced, vertically-orientated semiconductor channel elements that span longitudinally along the device between the source and drain regions. First and second gate structures are provided in the form of pluralities of spaced, castellated first and second gate elements interposed between the primary and secondary channel elements, respectively, with first and second top gate members interconnecting the first and second gate elements at their upper vertical ends to cover the primary and secondary channel elements. The adjoined primary and secondary channel elements are super-self-aligned from the first and second gate elements to the source and drain regions. Finally, first and second dielectric layers separate the primary and secondary channel elements from their respective gate structures.
