Abstract: A compiler module is disclosed which minimizes pipeline breaks by reordering object code instructions to avoid conflicts between closely grouped instructions to the extent possible. Representation of each object code instruction in a small sequential group is temporarily held in a buffer and is assigned a pair of Attribute Words. Potential conflicts which a newly called instruction may have with those instructions already in the buffer are ascertained by logically AND-ing its Attribute Words with those of the other instructions and examining the result. If a conflict does exist, an attempt is made to resolve it by determining if the conflicting instruction already in the buffer can be moved ahead of one or more other instructions in the buffer such that the conflict is eliminated or minimized. This procedure involves a comparison of the Attribute Words of the candidate instruction to be moved, I m , with the other instructions in the buffer. If movement of the conflicting instruction is possible and will resolve or minimize the conflict, the instructions in the buffer are reordered as appropriate.

Abstract: A magnetron sputtering method and apparatus employing an annular target comprising a single unitary block the thickness of which is varied to provide for a non-uniform removal of material during the sputtering process and having a concave continuously smooth surface with an inwardly facing portion close to and surround­ing the outer edge of a stepped wafer. Thus the block provides a sputtering surface with areas facing differently facing surfaces of the wafer steps. Two concentric erosion zones on the target surface are independently energized at different electrical parameter values by synchronizing the power applied to the single target with switched activation of plasmas overlying the respec­tive target regions which define the erosion zones. The electrical parameters and the geometry are established so as to uniformly coat the differently facing surfaces of the stepped wafer. During part of the duty cycle during which each target region is energized, parameters are measured. Such parameters may be those which vary with changes in geometry as for example may be due to target erosion. The operation of different target regions, such as the duty cycles or power levels for such regions, is separately varied in response to the measurements or otherwise, to maintain uniform substrate coating as the target erodes. The target has an annular pole piece embedded to reduce the space separating the target erosion regions, and includes means to cool the target and reinforce it against thermal expansion.

Abstract: Disclosed is a test system having an arbitrary waveform generator (64), a comparator (56), and a test controller (58) to analyze the arbitrary signal output (30) from a device under test (DUT) (50). The output of the device under test (50) is connected to one input of the comparator (56) and the output of the arbitrary waveform generator (64) is connected to the other input of the comparator (56). The test controller (58) stimulates the DUT (50), causing it to perform a function, and stimulates the arbitrary waveform generator (64), causing it to generate a limit envelope signal (32). The output of the comparator (56) is continuously monitored by the test controller (58) to determine whether the signal output (30) of the DUT (50) exceeds the limit envelope (32) created by the arbitrary waveform generator (64). If the output (30) of the DUT (50) exceeds the limit (32), then the DUT is in error. The test may be run twice to compare the DUT (50) output (30) to both upper (32) and lower (34) limits to determine whether the waveform output (30) of the device under test (50) fits within a limit envelope. In a second embodiment of the device, a pair of arbitrary waveform generators (128, 120) are used to create both the upper (32) and lower (34) envelope limits simultaneously, and each of these limit signals is connected to one input of a pair of comparators (104, 106). The DUT (50) output (30) is connected to both the other inputs of the comparators (104, 106). By sampling the output of both comparators (104, 106) simultaneously, a test controller (112) can determine, in a single test, whether the output (30) of the device under test (50) is within the envelope created by the waveform generators (118, 120).

Abstract: A circuit (10) provides North-South pincushion correction and gullwing compensation in a raster display of a television apparatus. A correction circuit (52,60,62,66) generates a generally parabolic, horizontal rate correction signal to correct for North-South pincushion distortion. A gullwing compensation circuit (72) is coupled to the correction circuit and forms a feedback path therein for amplitude modifying the correction signal to further correct for gullwing distortion. The gullwing compensation circuit amplitude modifies the generally parabolic signal (V OUT ) as a function of itself, achieving an equilibrium condition. A vertical deflection circuit drives a vertical deflection coil with the gullwing compensated correction signal. The correction circuit comprises a ramp waveform generator (60,62) having a controllable current source (52,54,56) generating a constant component of current (I DC ) for pincushion correction and a variable component of current (I AC ) responsive to the feedback signal for gullwing compensation. The variable component of current (I AC ) varies inversely to the feedback signal, which is coupled in the feedback path to the controllable current source through an inverting amplifier (72). The output of the inverting amplifier modulates the current supply (54) to modify the resulting shape of the parabolic signal to compensate for gullwing distortion by increasing the slope of the parabola on both lateral sides.

Abstract: The invention relates to a method of disposing of dusts containing toxic heavy metals, toxic organic substances and similar compounds and preferably originating from flue gas purification from, for example, refuse incinerators. The dusts are mixed with one or more additives to give a fusible blend and thermally treated. The glass formed can be taken to a higher-value re-use, and the hot waste gases arising during the fusion process are mixed with the dedusted and cooled waste gases of the refuse incinerator directly upstream of the entry to an HCl scrubber. Cooling to temperatures of 45 DEG  to 80 DEG C is effected by injection of aqueous hydrochloric acid and/or water. The dilute hydrochloric acid formed in the HCl scrubber is separated by rectification into concentrated hydrochloric acid and a bottom fraction. The heavy metal compounds, salts and residual dusts which have remained in the dedusted flue gas and in the waste gas of the fusion process are enriched in the bottom fraction, separated off and must then be put into a landfill. <IMAGE>

Abstract: A method and apparatus of detecting knocking in an internal combustion engine having a crankshaft (4) uses a knock detecting sensor (17) to detect vibration caused by knocking. The signals from the knock detecting sensor (17) are detected between a first and a second moment of time (i.e. a measurement window) and at least one of the first and second moments of time are independently varied in dependence upon a vibration spectrum of frequencies to be detected. In a preferred embodiment a plurality of frequency spectra, each having a different first and second moment of time, are each separately analysed for determining knock intensity. The moments of time are represented by first and second angles of the crankshaft. A plurality of measurement windows are advantageously used to determine the level of knocking and if the level exceeds a predetermined level the ignition timing for the engine is retarded. The frequency of maximum amplitude is arranged in operation to be the centre frequency of a frequency spectrum determined by the measurement window.
