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.

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.

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.

A multi-staged gas turbine engine fuel supply system includes a plurality of fuel injectors and at least first and second staged fuel injection circuits in each of the fuel injectors. Each of the first and second staged fuel injection circuits includes first and second fuel injection points and at least first and second fuel nozzle valves operable to open at different first and second crack open pressures and controllably connected to the first and second staged fuel injection circuits, respectively. A single fuel supply manifold is connected to all of the fuel nozzle valves. A single fuel signal manifold is controllably connected to all of the first and second fuel nozzle valves. The fuel injector may have a valve housing with one of the first fuel nozzle valves and one of the second fuel nozzle valves contained therein.

An electric oven which has a plurality of heating positions for controllably heating foodstuff thereon includes temperature selection means for locally and remotely selecting the heating temperature, and timing means for locally and remotely setting the heating duration of each of the heating positions, respectively. Display means are provided for selectively showing the remaining heating duration locally and remotely following setting of the timing means for the heating duration of the cooking positions, respectively, and switching means are employed for selectively turning the heating positions on and off in response to the respective preset heating durations.

The present invention is directed to composition for straightening or relaxing hair containing: (a) at least one hydroxide-containing active ingredient; (b) at least one polyhydric alcohol having 4 or more carbon atoms and two hydroxyl groups; (c) optionally, at least one nonionic surfactant having an HLB of from about 8 to about 20; (d) optionally, at least one amphoteric and/or zwitterionic surfactant; and (e) remainder, to 100%, of a cosmetically suitable medium.
摘要:
A method representing an object appearing in still or video image for use in searching, wherein the object appears in the image with a first two-dimensional outline, by processing signals corresponding to the image, comprises deriving a view descriptor of the first outline of the object and deriving at least one additional view descriptor of the outline of the object in a different view, and associating the two or more view descriptors to form an object descriptor.
