Patent EP-0147587-A2 (EP)
Inventor: CASTELLANO ANTHONY JOSEPH JR
IPC: G01N21/956
Filed: 1984-11-09
Abstract: Recombination center defects in an oxidized semiconductor wafer (68) are imaged by charging the oxide in a corona discharge (30, 40) and then passing the charged wafer past a stationary bifurcated electrode (70). A focused beam from a laser (60) is scanned between the arms of the bifurcated electrode and along its length as the wafer is slowly moved transversely to the direction of laser scanning. The signal from the bifurcated electrode is displayed in an imaging system (74), one axis of which is synchronized to the laser scanning and the other axis is synchronized to the movement of the wafer.

Abstract: Deactivation of silica, alumina, silica-alumina and aluminosilicate amination catalysts by coke is inhibited by carrying out the amination reaction in the presence of hydrogen. Alternatively, the coked catalysts may be regenerated in the presence of a stream of hydrogen or of hydrogen and ammonia at somewhat lower temperatures than those commonly used in processes for coke removal by oxidation, thereby reducing the risk of structural damage to the catalyst.

Abstract: An aqueous starch composition is hydrolysed to give a dextrose-containing product. The dextrose is separated from the product by passing the product through a chromatographic column or bed to absorb the dextrose and to produce an aqueous raffinate. The dextrose is then eluted from the chromatographic column or bed using an eluant which at least partly comprises an aqueous dextrose-containing solution formed by treating the aqueous raffinate produced above with an immobilised glucoamylase enzyme.

Abstract: A sense amplifier for a circuit having a complementary output, such as a static MOS memory device, has a clamping means (0 7 , Q 8 ) connected between the output terminals (OUT1, OUT2) of the sense amplifier. The clamping means clamps the differential output voltage to a value which is sufficiently low to reduce the time delay of the output signal, in order to obtain a high switching rate of the sense amplifier, but still sufficient to keep the output voltage at the level necessary to operate a subsequent circuit of the device.

Abstract: In a control valve (15) for a power-assisted rack-and-pinion steering apparatus having a slidable member (16) adapted to sense the axial movement of a helical tooth pinion (5), pre-stressed spring means (21) ensure the return of the slidable member (16) of the valve into its central neutral position, against the friction forces existing in the whole apparatus. These means also avoid intervention of power-assistance below a predetermined value of the torque onto the pinion. In one embodiment of the control valve which operates in connection with a closed center air circuit, means are provided to minimize the friction forces allowing at the same time the use of a simple and inexpensive structure.

Abstract: A closed-cycle gas scrubbing or purification system is described for noble gas and fluorine mixtures, such as are typically used in rare-gas fluoride (excimer) lasers (10). In a first reaction zone (14), the fluorine in the gas mixture is converted to titanium tetrafluoride vapor by reaction with titanium at a temperature above 150 degrees C, preferably at about 300 degrees C. The TiF 4  vapor is then removed without passivating the titanium by condensing the TiF 4  vapor in a separate condensation zone (20) held at a temperature below the temperature of the first reaction zone, preferably at about room temperature. After condensing the TiF 4  from the gas mixture, any silicon tetrafluoride in the mixture is chemically removed by contacting the gas mixture with an alkaline earth oxide (preferably either CaO or MgO) in a second reaction zone (36). Residual contaminants (i.e. contaminants other than SiF 4 ) are removed from the gas mixture by contacting the gas mixture with a metal getter (prefarably titanium of zirconium) at a temperature above 600 degrees C, preferably about 900 degrees C or more. The hotmetal gettering preferably is done in the second reaction zone by mixing or layering the metal getter with the alkaline earth oxide and heating the second reaction zone to a temperature above 600 degrees C. Fresh halogen gas is added to the purified rare-gas mixture before it goes back to the laser. Since SiF 4  is specifically removed, it is acceptable to use industrial grade titanium to remove the fluorine and as a hot metal getter for residual contaminants.

Abstract: This apparatus uses as transmission medium the lines of electricity supply systems and allows simultaneous communication between a multiplicity of transmitters 1, 2, 3 and receivers 4, 5, 6, 7 without mutual interference. This multiple access apparatus is resistant against interference inherent in the mains, particularly against interference or attenuation which only relates to a part of the transmission frequency band. To achieve this, a multiplicity of discrete frequencies is used from a set of frequencies preferably above the audio frequency range. From this set, the instantaneous transmitting frequency of each transmitter is selected in accordance with a predetermined plan and in accordance with a timing pattern, common to all transmitters 1, 2, 3 and receivers 4, 5, 6, 7, which is preferably derived from the mains voltage frequency, and is varied in hops. Each transmitter 1, 2, 3 has its own pattern of variation, with the aid of which it can be selectively received by the receiver(s) 4, 5, 6, 7. <IMAGE>

Abstract: A computer (100) having a cache memory (112) and a main memory (14) is provided with a transformation unit between the main memory and the cache memory so that at least a portion of an information unit retrieved from the main memory (14) may be transformed during retrieval of the information (fetch) from the main memory and prior to storage in the cache memory (cache). In a specific embodiment, an in­struction may be predecoded prior to storage in the cache memory (112). In another embodiment involving a branch instruction, the address of the target of the branch is calculated prior to storing in the instruction cache. The invention has advantages where a particular instruction is repetitively executed since a needed decode operation which has been partially performed previously need not be repeated with each execution of an instruction. Consequently, the latency time of each machine cycle may be reduced, and the overall efficiency of the computing system can be improved. If the architecture defines delayed branch instructions, such branch instructions may be executed in effectively zero machine cycles. This requires a wider bus and an additional register in the processor (116) to allow the fetching of two instructions from the cache memory (112) in the same cycle.
