A parallel bit correlator for recognizing a predetermined bit pattern including a predefined number m of bits in a stream of data bits including identifying successive sets of m bits in a stream of data bits and simultaneously comparing each of the sets of m bits to the predetermined bit pattern for detecting the presence of the predetermined bit pattern in the stream of data. A second hand lever, which consists of steel and is joined to the casing so as to pivot on a shaft, bears a pinion sector surrounding the shaft. Some embodiments include methods of titanium deposition in which a semiconductor material surface and an electrically insulative surface are both exposed to titanium-containing material, and in which a titanium-containing film is uniformly deposited across both surfaces. As the combine becomes laterally inclined on a hillside, the weighted member changes its angular position relative to the combine. In one embodiment, a source of RF power is coupled to a lid of the chamber, while a switch is used to couple a showerhead to ground terminals or the source of RF power. At least one helical electrode is fitted over the distal portion of the insertion tube.
