Abstract: An axial flow carbon black reactor (10) for producing carbon black particles having a relatively narrow particle size distribution. Feedstock oil is introduced into the reactor by a spray nozzle (12) located coaxial with the longitudinal center line of the reactor. The oil spray flows either in the countercurrent or the concurrent direction relative to the flow of hot gas through the reactor and produces an oil spray pattern covering either substantially the entire frontal area of the hot gas flow or substantially less than the frontal area. Countercurrent feedstock flow from (23) increases coverage of the gas flow area by the oil spray and narrows the particle size distribution of carbon black produced by the reactor, and concurrent feedstock flow produces the opposite result.

Abstract: A color printing system for color-printing images or characters on a surface of a writing sheet. The color printing system comprises a plurality of printing heads (A→D) which are successively arranged in parallel to each other and a feeding device for moving the writing sheet in a direction perpendicular to the head-reciprocating directions. Each of the printing heads linearly reciprocates so as to go and return in directions along the surface of the writing sheet for the color printing and has a plurality of ink-discharging nozzles (I→N). The plurality of ink-discharging nozzles are successively arranged with a pitch which is equal to or greater than the twice pitch of lines to be finally printed by the printing heads so as to write the images or characters on the writing sheet. The feeding device moves the writting sheet in a direction perpendicular to the head-reciprocating directions. When each of the printing heads (A→D) performs the going-direction printing operation, the feeding device moves the writting sheet by a distance corresponding to M times of the line-printing pitch where M is a predetermined number, and when the same printing head performs the returning-direction printing operation, the feeding device moves the writting sheet by 2N - M where N is the number of the ink-discharging nozzles (I→N).

Abstract: A communications receiver for a code division multiple access (CDMA) satellite communication system is disclosed in which a plurality of data carriers share the same band. A pilot carrier transmits a timing reference used by all receivers to acquire the clock used in timing the code generators, and used as a frequency and phase reference for data detection. This receiver employs a digital signal processor that detects a spread pilot carrier and uses the phase noise on the pilot carrier to subtract the communication link phase noise from the data carriers, thus allowing communication at lower signal-­to-noise ratios.

Abstract: In a device for atomising at least one jet of a liquid or solid material, preferably molten metal, the atomising process takes place in a stationary ultrasonic field which is produced between at least one pair of ultrasonic vibrators. In order to increase performance, a plurality of atomising fluid jets, and in a complementary fashion thereto additional fluid jets (e.g. gas) are introduced from nozzles in each node point area of the stationary ultrasonic wave. In this way, the atomisation fluid mass throughput is very greatly increased and thus the atomisation power raised. In addition, special sonotrode shapes are proposed in order to increase the performance further. <IMAGE>

Abstract: A semiconductor body (100) has a first device region (20) of one conductivity type forming with a second device region (13) of the opposite conductivity type provided adjacent one major surfacee (11) of the semiconductor body (100) a first pn junction (40) which is reverse-biassed in at least one mode of operation. A floating further region (50) of the opposite conductivity type is provided within the first device region (20) remote from the major surfaces (11 and 12) of the semiconductor body (100) and spaced from the second device region (13) so that, in the one mode, the depletion region of the first pn junction (40) reaches the floating further region (50) before the first pn junction (40) breaks down. The floating further region (50) forms a further pn junction (51) with a highly doped capping region (60) of the one conductivity type which is provided within the first device region (20) between the floating further region (50) and the second device region (13) and spaced from the second device region (13) and which enables a high electric field to exist between the first pn junction (40) and the further floating region (50) with less risk of the device breaking down.

Abstract: An analogue circuit or unit under test (34) is tested utilising automatic test equipment (30) and an interface unit (35) to apply stimuli to the circuit (34), the stimuli including supply potentials. A computer (32) analyses the circuit (34) as a network of nodes and modules to deduce a set of ranges of values at selected nodes, the ranges being determined from the set of the stimuli and a resultant set of test measurements, taken from nodes of the circuit by means of the interface (35) and automatic test equipment (30), taking into account tolerances in the stimuli, the measurements and the nominal parameters of components of the circuit. If there is inconsistency among the derived ranges the computer (32) treats as potentially faulty any module which could remove the inconsistency if the constraints imposed by that module were suspended. The computer (32) controls an iterative, hierarchical process involving repetition of the sequence of steps using different sets of stimuli and/or measurements and/or different analyses of the circuit into nodes and modules, in particular with analysis in terms of successively smaller modules. In this way, the location of faults can be progressively narrowed down and corresponding output information can be given in a device (40) such as a VDU or printer.

Abstract: Software simulators of logic design circuits run slowly but are capable of providing very finely detailed error trace analyses. On the other hand, hardware accelerators (70, 200) operating to perform similar functions are very fast in their execution but are not capable of practically isolating error states or other critical conditions. Accordingly, the present invention provides an interactive system combining software simulators and hardware accelerators (70, 200) so that when desired test results do not favorably compare with simulated results, a mechanism is provided for storing the current hardware accelerator (70, 200) state and restoring the accelerator to a previous checkpoint state which has been saved as a result of a prior periodic interruption. The hardware accelerator (70, 200) is then operated for a time sufficient to bring it up to a state that occurs just before the detected miscomparison. At this point, state information from the hardware accelerator (70, 200) is supplied to a software simulator for detailed error analysis and fault tracing. The hardware accelerator (70, 200) may then be restarted where it left off or with a different task. In this way, optimal utilization is made of expensive hardware accelerator (70, 200) resources while nonetheless providing error event isolation and the ability to generate detailed traces of simulated behavior.
