Patent EP-0413133-A2 (EP)
Inventor: EVANS TIMOTHY GLENN
IPC: G06F11/25
Filed: 1990-07-11
Abstract: An apparatus automatically generates test programs to test a service processor associated with a computer. The apparatus comprises a knowledge base for mapping screens generated by the service processor, which screens are arranged in a hierarchical manner and comprise menu screens which access other screens lower in the hierarchy and end point screens which represent memory of the computer serviced by the service processor. The apparatus also includes a user interface for selecting at least one screen generated by the service processor, which screen identifies a branch of screens lower in the hierarchy for testing. A program generator is coupled to the user interface and the knowledge base, and identifies from the knowledge base the screens in the branch. The program generator also generates a program to direct the service processor to call up the screens in the branch, and test the pathing between the screens by comparing the map provided by the memory to the screens actually called up by the service processor. To reduce the testing time, the program generator can select a fraction of the paths in the branch for testing. The program generator also writes a program to direct the service processor to exercise the end point screens to determine if the service processor is able to write data into the memory of the computer.

Abstract: The continuous casting of metal strip (21) using the melt overflow process is improved by controlling the weir conditions in the nozzle (19) to provide a more uniform flow of molten metal (12) across the width of the nozzle (19) and reducing the tendency for freezing of metal along the interface with refractory surfaces. A weir design having a sloped rear wall (28) and tapered sidewalls (29) and critical gap controls beneath the weir (26) has resulted in the drastic reduction in edge tearing and a significant improvement in strip (21) uniformity. The floor (34) of the container vessel (18) is preferably sloped and the gap between the nozzle (19) and the rotating substrate (20) is critically controlled. The resulting flow patterns observed with the improved casting process have reduced thermal gradients in the bath, contained surface slag and eliminated undesirable solidification near the discharge area by increasing the flowrates at those points.

Abstract: In a multistep aluminum sputtering process aluminum is sputtered onto the surface of a semiconductor wafer (13) and low areas (14) between closely spaced apart raised portions (11, 12) on the wafer, such as closely spaced apart steps, narrow trenches, or small diameter vias, are completely filled in by the sputtered aluminum (20). This results in the formation of an aluminum layer (20) which is not thinned out in such low areas, and which has a surface which ranges from substantially planar to a positive slope, such as shown at (24') and (26') in Figure 2. The first step is carried out by sputtering from about 20 to about 200 nm (200 to about 2000 Angstroms) of aluminum while the wafer temperature is within a range of from about 50°C to about 250°C and the sputtering plasma is at a power level of from about 1 to about 16 kilowatts. The power level range is then changed to from about 14 to about 20 kilowatts, a DC or AC bias is applied to the wafer, and aluminum is then sputtered either for an additional time period of about 20 to about 45 seconds or until the wafer temperature reaches 500°C, whichever occurs first, in a second step. Then the back side of the wafer is contacted by a thermally conductive gas to control the wafer temperature while further aluminum is optionally sputtered onto the wafer for an additional 0 to 45 seconds in a third step.

Abstract: A teaching method for a recurrent neural network (10) having hidden (16), output (14) and input (12) neurons calculates weighting errors over a limited number of propagations of the network. This process permits the use of conventional teaching sets, such as are used with feedforward networks, to be used with recurrent networks. The teaching outputs are substituted for the computed activations (Z(3), Z(4)) of the output (14) neurons in the forward propagation and error correction stages. Back propagated error from the last propagation is assumed to be zero for the hidden (16) neurons. A method of reducing drift of the network with respect to a modeled process is also described and a forced cycling method to eliminate the time lag between network input and output.

Abstract: An apparatus for atomising a liquid comprises an annular housing (32) which has a radially inner curved annular Coanda surface (34). The housing (32) has an outlet (40) in its radially inner circumferentially extending side which supplies a first pressurised fluid onto the Coanda surface (34). Diametrically opposite, confronting, surface portions (31,33) of the Coanda surface (34) define a convergent/divergent passage (35,37,39). A liquid is discharged from a nozzle (42) into the convergent portion (35) of the convergent/divergent passage so that a stream of liquid is positioned between the confronting surface portions (31,33). A second fluid is entrained by the first fluid (F) flowing over the Coanda surface (34). The second fluid (G) flows between the first fluid (E) and the stream of liquid, and the liquid is atomised as it interacts with the flow field generated by the apparatus. The liquid stream is automatically centralised between the confronting surface portions (31,33) to give uniform atomisation.

According to the invention, the cache memory is segmented to operate at a selected working segmentation level, and at least two virtual cache tables (52, 54) are segmented to operate, respectively, at the working segmentation level and at least one different segmentation level. Instructions received from a host computer (4) are stored in an instruction queue (50). Then, while the storage system is in an idle state, hit ratio simulations are performed on the virtual cache tables by executing a selected number of instructions stored in the instruction queue. The working segmentation level is subsequently adjusted to equal the segmentation level of the virtual cache table having the highest hit ratio.

Abstract: Described is an optical disk drive apparatus including an optical disk employing spiral tracks. The spiral tracks are delimited by a track boundary which extends radially across the disk. An optical head is movable over the disk surface and a track crossing signal is generated for every track crossed by the head. When commencing a seek operation from a current track to a target track, control means of the apparatus calculates the number of track crossing signals to be counted during the seek. This calculation takes account of any crossing of the track boundary during the seek and thus the calculated number of track crossings does not necessarily correspond to the track to track distance between current and target track.

Abstract: Bandwidth balancing is accomplisbed in DQDB networks that handle multi-priority traffic by causing each node to throttle its own rate of transmission in accordance with the priority of the data that the node transmits. In accordance with one approach, each node limits (24,37) its throughput to the product of a bandwidth balancing factor (which is a fraction that varies according to the priority level of data) and the unused bus capacity. When parcels of different priorities are received within each node, the parcels are processed in priority order. In accordance with another approach, all active parcels within a node are handled concurrently and receive some bandwidth. The throughput of each parcel in a node is limited to the product of the bandwidth balancing factor and the unused bus capacity. In accordance with still another approach, each traffic parcel limits its throughput to the product of the bandwidth balancing factor and the bus capacity unused by parcels of equal or higher priority. This scheme allocates bandwidth first to the higher-priority parcels, then allocates the leftovers to the lower-priority parcels. Lower-priority parcels have no effect on The steady-state throughputs of higher-priority parcels.
