IPC: F04C2/10

Abstract: The invention provides a variable output pump of the gerotor type in which one rotor (16) meshes in two side by side annulii (14, 12) which can be aligned for maximum output and turned in opposite directions to be non-aligned for minimum output. The movement is effected by a gear train (20, 24, 29) displaced by a rack (40) which is hydraulically operated by pump pressure. Hence high pressure displaces the rack to result in lower output against lower pressure. A variation is described in which a control spool diverts fluid to either side of the piston according to need and this is displaced in one direction by the derived fluid pressure and in the other direction additionally by spring pressure transferred from the piston position by a lever system. This can give desired pump output/speed results at reduced power consumption.

Abstract: An ion beam neutralizer (10). High energy electrons (40) are directed through an ion beam neutralizing zone or region containing an ionizable gas. As the high energy electrons collide with the gas molecules, they ionize the gas molecules and produce low energy electrons which are trapped by a positively charged ion beam (14). As high energy electrons pass out of the neutralizing zone they are deflected back to the neutralizing zone by a cylindrical conductor (30) biased to deflect the high energy electrons and an accelerating grid (50) for accelerating the electrons back through the beam neutralizing zone.

Abstract: A semiconductor photodetector has a simple structure consisting of a semiconductor substrate, first and second Schottky electrodes formed on the substrate with a predetermined distance therebetween. A substrate surface between the first and second Schottky electrodes is made a light-receiving surface. An internal amplification function can be realized with a low bias voltage, by determining the distance between the Schottky electrodes so that an internal amplification factor G ( = τ/t ) becomes not less than 1.0, where τ and t represent a carrier lifetime and a carrier traveling time between the Schottky electrodes. The photodetector is applicable to detection of extremely weak light by virtue of its very small dark current.

Abstract: An improved contact is obtained to power devices having a raised dielectric region (18) adjacent the die contact region (22) by providing a contact dimple (32,42,52) on the otherwise flat metal lead (30,40,50) used for die contact. The dimple (32,42,52) is arranged above the die contact (22) and soldered thereto. The radius of curvature and depth of the dimple is adjusted so that the contact lead (30,40,50) is far enough away from the edge of the surrounding raised dielectric (18) at the edge (34) of the die contact (22) to provide a laterally concave outward air-solder interface in that location. This prevents solder creep onto the dielectric surface (23) and avoids die edge shorting. Several dimpole shapes (32,42,52) are described.

The generality of diagnosis is accomplished by focusing on components that make up the machine rather than individual machines as a whole. The apparatus architecture also permits diagnosis of machines based on other parameters such as amperage, torques, displacement and its derivatives, forces, pressures and temperatures. The apparatus includes an inference engine which links the rules in a backward chaining structure.

IPC: A61B17/06
Filed: 1989-08-23
Abstract: A molded two-piece (12, 14) suture package is disclosed which encloses and defines an oval channel (30) in which sutures (60) may be wound. The oval channel (30) has two semicircular end sections (32, 33) connected by straight side sections (34). An opening (38) in the channel (30) is provided at the juncture of a straight section (34) and an end section (33), permitting sutures (60) to be withdrawn from the channel (30) at the end of a straight section (34). In a preferred embodiment the interior wall of the channel (30) is formed by alternating engaging sections (32-36) formed in the respective package pieces (12, 14). To prevent the wrapped suture (60) from becoming entrapped when the two pieces (12, 14) are engaged, the top and bottom of the channel (30) is alternately raised (26', 30') and lowered (26'', 30'') in alignment with the alternating wall sections, causing the wound suture (60) to bridge those areas where it may become entrapped between the mating package pieces (12, 14). Entrapment of the suture (60) end at the outside of the channel (30) is prevented by alternately recessing the outer wall of the channel (30). Flexible molded needle (70) parks are also disclosed for the package.

Abstract: A process for manufacturing selectively doped heterostructure field-­effect transistors (SDHTs), a desired wafer structure for SDHT fabrication and a method for isolating SDHTs on the wafer are disclosed herein. The wafer has epitaxial layers grown on a substrate. The layers are: a buffer layer of GaAs, a first spacer layer of AlGaAs, a donor layer of AlGaAs, a second spacer layer of AlGaAs, a first cap layer of GaAs, an etch-stop layer of AlGaAs and a second cap layer of GaAs. A protective layer of AlGaAs may then be grown on the second cap layer to protect the second cap layer from contamination or damage. Also a superlattice may first be grown on the substrate. Openings are made in the protective layer and then in the second cap layer where enhancement type SDHTs are to be formed. The remaining protective layer is then etched along with the exposed etch-stop layer with a selective etch to expose the first cap layer and the second cap layer where respective enhancement-type SDHTs and depletion-type SDHTs are to be formed. Gate electrodes for corresponding SDHTs are then formed on the exposed first and second cap layers and a subsequent selective dopant implant forms self-aligned SDHT structures. Multiple layers of dielectric and metal are then deposited to interconnect the SDHTs. The selective etch of the AlGaAs protective layer and the etch-stop layer results in consistent threshold voltages of the SDHTs across the wafer. The isolation of SDHTs is accomplished in a two step isolation involving implanting isolation dopant (e.g., oxygen) into the epitaxial layers.

Abstract: In a method and apparatus for reducing frequency burst noise and noise spikes accompanying a random pulse signal, pulses with an amplitude above a high threshold or below a low threshold are eliminated, with the remaining pulses of intermediate amplitude being statisti­cally filtered. The statistical filter compares the current pulse count rate signal to maximum and minimum statistical limits generated from the recent average value of the pulse count rate using Poisson statistics, and clamps the output to the limit which is exceeded. If the pulse count rate is between the statistical limits, it is used as the output pulse count rate signal. If the statistical limits are exceeded for a designated interval indicative of a true change in the pulse count rate, clamping of the output signal is overridden so that the true change in pulse count rate can be tracked. Statis­tical filtering is resumed when the current pulse count rate is again within the statistical limits.

Abstract: Knitted joins are made in double jersey knitted articles using a method which minimises the effect of hole formation at the join. Single jersey edges (14, 18) are knitted along the edges (8, 9) to be joined, being knitted on from one to six needles in each of the courses of knitting which form part of the edge of the join. The edgings (14, 18) need not extend along the whole length of the join. In a further embodiment superimposed strips (15) of single jersey knitting are knitted between the edgings (14, 18) so as to split hole formation into two smaller series which are less noticeable. With this embodiment, one or both edgings (14, 18) can be omitted. The method is useful for upholstery fabric joins, par­ticularly for vehicle seat covers, where exposure of the padding is to be avoided.
