Abstract: A multitasking data processing system is provided with a hardware-configured operating system kernel. The system includes a processor queue (20) that includes a plurality of word stores (52,54), each word store (52,54) storing a task name, in execution priority order, that is ready for processing. An event queue (24) in the kernel includes a plurality of word stores (52,54) for storing task names that await the occurrence of an event to be placed in the processor queue (20). When an associated processor (10) signals the occurrence of an event, matching logic (77) searches all word stores (52,54) in the event queue (24), in parallel, to find a task associated with the signalled event and then transfers the task to the processor queue (20). Shift logic (73) is also provided for simultaneously transferring a plurality of task names, in parallel, in the processor queue (20) to make room for a task name transferred from the event queue (24).

Abstract: In a testing device (PRE), with the aid of which the functional testing of circuit boards (VPL) equipped with programmable integrated circuits (PIS) is provided by means of measuring sensors (MF1...MFn) - usually in the form of needle adaptors - additional means for generating circuit-specific programming signals (ps) and at least one additional circuit-specific programming routine (PR) are arranged. As a result, a programming of programmable integrated circuits (PIS) on equipped circuit boards (VPL) is accomplished as part of functional testing. With the aid of the method according to the invention a considerable reduction in cost is achieved in the production of circuit boards (VPL) or assemblies with programmable integrated circuits (PIS) by the avoidance of separate programming on a special programming terminal and program-individual stock keeping of the programmed integrated circuits (PIS). <IMAGE>

According to the method of the present invention, the WSix film is formed in a CVD reactor operating at a low pressure and at a wafer temperature between about 300 and 550°C. In the preferred embodiment, a thin nucleation layer is deposited before the WSix film. The deposited WSix films exhibit low flourine concentrations with good within-wafer uniformity and process stability. The attached plot illustrates a comparison the growth rates (given as the weight in mg per deposition time in Min) versus the wafer temperature in °C, using DCS (curve 10), DCS + SiH₄ (curve 12) and DCS + H2 (curve 14).

Abstract: The torque converter (12), gearbox (11) and heat exchanger (14) are all connected to a common control valve (16) which regulates the fluid flow for optimum cooling. In the start-up phase, with cold fluid, the control valve isolates the torque converter circuit and the gearbox circuit to ensure rapid warming of the fluid circuits in both systems. At high temperatures both fluid flows are ducted through the heat exchanger. The system provides for intermediate temperatures in which the return flow from the torque converter is split between the heat exchanger and returning to the input side of the torque converter, with the lost fluid made up with fluid from the gearbox circuit.

Abstract: The present invention relates to the detection of errors in seismic data and in particular to apparatus for detecting errors in frames of seismic data that can be presented as images. Due to the techniques used for collecting seismic data, an image produced to represent that data will typically be expected to exhibit an inherent symmetry about an axis. The apparatus of the present invention comprises a storage device for storing a frame of seismic data which can be presented as an image, a selection device for selecting an axis within the image as the axis of symmetry, and a divider for dividing the data about the axis of symmetry to create first and second sets of data. Further it includes a comparison means for comparing the sets of data according to preselected matching criteria to determine, based on the degree of matching, whether the extent of mismatch in the frame of data is within a predetermined tolerance.

Abstract: Apparatus for constructing a complex artifact out of primitive artifacts and other complex artifacts. The apparatus has a permanent knowledge base of primitive artifacts, previously-made complex artifacts, and rules defining how complex artifacts are made from primitive artifacts. All artifacts in the permanent knowledge base have been checked for consistency. Artifacts from the permanent knowledge base are displayed in a search area as directed graphs in which the artifacts are represented by nodes. A user may search the permanent knowledge base, and the directed graphs in the search area show the results of the search. To construct a new complex artifact or to add to a complex artifact under construction, the user selects nodes of the directed graphs which represent desired component artifacts. Information about the desired artifacts is copied from the permanent knowledge base to a working knowledge base and a directed graph of the contents of the working knowledge base is displayed in a work area. When information is added to the working knowledge base, consistency checks are made using the rules and the information in the permanent knowledge base. The results of the consistency checks appear in the display in the work area. A user may store an artifact under construction in the permanent knowledge base. A mapping editor permits the user to determine how object artifacts are mapped to the displays of the directed graphs.
