    摘要: A semiconductor device, such as a metal-oxide semiconductor field-effect transistor, includes a semiconductor substrate, a drift layer formed on the substrate, a first and a second source region, and a JFET region defined between the first and the second source regions. The JFET region may have a short width and/or a higher concentration of impurities than the drift layer. The semiconductor device may also include a current spreading layer formed on the drift layer. The current spreading layer may also have a higher concentration of impurities than the drift layer.

    摘要: A splitter valve for splitting an inlet stream into a plurality of outlet streams. The valve comprising an inlet (31) and a plurality of outlets, one for each outlet stream. An outer sleeve (20) has a plurality of first outlet orifices (32, 33), one for each stream. An inner element (30) is moveably retained within the outer sleeve and has an inlet and a plurality of second outlet orifices (32, 33), one for each stream. The relative proportion of the inlet stream fed to each outlet is determined by the relative position of the inner element and outer sleeve. The first and second outlet orifices are shaped such that the flow through each outlet varies substantially linearly with the relative position of the inner element and outer sleeve.

    摘要: A drive assembly, particularly for driving arms around a compartment in a waste material digester, comprises a rotatable hub having an inner drive plate and a ratchet plate secured thereto for rotation therewith. Positionally opposed, parallel piston and cylinder drive means recipocatably drive an outer drive plate, drive arms pivotally carried on the outer drive plate engaging with drive pins on the inner drive plate to drive the hub in one direction. Movement of the hub in the opposite direction is prevented by latches engaging with respective shoulders of the ratchet plate when the outer drive plate moves in said opposite direction.
