Abstract: A bipolar transistor (134) and two field-effect transistors (130, 132) are connected in a BiCMOS pull-down configuration to pull-down to a (first) predetermined potential level the potential developed on an output line when a high logic level potential is developed on an input line. To maximize switching speed and to minimize ground bounce (transients), the bipolar transistor is not permitted to go into saturation. A pair of transistors, connected in an inverter configuration, develop a signal which indicates when the bipolar transistor pulls-down the level of the potential on the output line below a (second) predetermined potential level. From a signal developed from the input line signal and a signal developed from the inverter developed signal, a gate develops a signal which drives a transistor (176) that pulls-down from the (first) predetermined potential level to a low logic level potential the output line potential three gate delay times after the output line potential level falls below the (second) predetermined potential level.

Abstract: First, a steel wire (1) is continuously dipping in molten copper or molten copper alloy so that copper or copper alloy builds up and solidifies on the peripheral surface of said steel wire, thereby obtaining an initial copper-clad steel wire (2). Then, the initial copper-­clad steel wire (2) is subjected a first cycle of hot rolling by a caliber roll. The hot-rolled wire is dipped in molten copper or molten copper-alloy (21) at least once so that copper or copper alloy builds up and solidifies thereon, thereby obtaining a final copper-­clad steel wire. 
     The final copper-clad steel wire is hot-rolled at a temperature of 750 to 850°C and with a rolling ratio of 10 to 40%. Then, the hot-rolled wire is cold-rolled with a reduction of area of 20% or more. 
     Thus, 75 to 90% of the cross sectional area of the obtained copper-clad steel trolley wire is occupied by the copper or copper alloy covering layer (3) so that the electric conductivity of the trolley wire is very high as 80% IACS or more. Moreover, the cast rod (2) is hot-rolled so that the core (1) and the covering layer (3) are metallurgically bonded to each other, thereby obtaining a copper-clad steel trolley wire whose core and covering layer are firmly bonded. Also, the hot-­rolled wire is cold-rolled so that the trolley wire with a high strength is obtained.

Abstract: The present invention relates to a method for determining at least one dynamic flow characteristic of a multiphase flow circulating in a pipe, said flow being composed of at least a lighter dispersed-phase and a heavier continuous-phase. A tracer is discharged (or activated) into the flow at a chosen first location in the pipe by mixing (or activating) at least a portion of the tracer with the continuous-phase therein. The tracer concentration at at least a chosen second location in the pipe is measured with a detector as a function of time t, so as to obtain at least one signal S(t). Then a relationship is fitted to the signal S(t) so as to derive the values of the velocity U of the continuous phase and/or of a dispersion coefficient k. The slip velocity v s  of the dispersed phase relative to the velocity of the continuous phase is also advantageously determined. 
     From the values of velocities U and v s  and from the volume fraction y l  of the continuous phase in the pipe (obtained by an ancillary measurement), the volumetric flow rates of the continuous and dispsersed phases are determined.

Abstract: The invention relates to an armour-piercing projectile of the type which comprises a nose cone (1) with a rein­forced tip (2) for mechanical penetration of reactive armour and an impact contact member (5), placed in the nose cone, for triggering the actuation part of the projectile upon impact against a target. The casing of the nose cone has a weak point (12) where the casing is designed to be deformed and make electrical contact with the contact member (5) upon impact of the projectile against a target. In order to prevent undesired particles in the form of metal shavings or the like from coming in between the casing and the inner shell of the contact member, a sealing ring (14) is inserted between the casing and the inner shell (5) at the rear part of the nose cone. This reduces the risk of unintentional contact function caused by such shavings or flakes situated between the shells in those parts where the contact distance is small.

Abstract: In a road surfacing for areas able to bear traffic, principally in the region of filling stations, directly below the road surface (3), for example of composite paving stones (4), there is an impervious course (2) of a mixture of clay minerals, for example montmorillonite, and other mineral substances. This mixture is made up of fractions of different grain sizes in such a way that the volume of the finer grain size is in each case greater than the pore volume of the respectively coarser grain size and the greatest grain of the finer grain size is equal to or less than about 1/10 of the smallest grain of the coarser grain size. The mixture is laid in the dry, cohesionless state and, once the paving stones (4) have been put in place, is compacted by vibrating the latter by means of a surface vibrator. During this process, the finer grains respectively fill the pore spaces of the coarser grain size; excess fines rise upwards and fill from the bottom the joints (6) between the individual components (4). The moisture required for the effectiveness of the mixture as an impervious course is supplied after laying. <IMAGE>

Abstract: A semiconductor device of multilevel wiring construction where a plurality of wiring layers (103,203) are deposited so as to contain an interlevel insulating layers therebetween. The interlevel insulating layers of a semiconductor device according to the present invention have sandwich-like constructions, in which the lowermost film is the first silicon oxide film (104) deposited by plasma vapor deposition method, the intermediate spin-coated film (105) fabricated by means of spin-coating and curing method, and the uppermost film is the second silicon oxide film (106) made by means of plasma vapor deposition method. The first silicon oxide film has high film density, while the second oxide film has low film density. 
     In the semiconductor device according to the present invention, the outgas generated at sputtering of the second wiring layers from the spin-coated film is released through the second silicon oxide film and does not concentrate in the through holes. Therefore, no corrosion of the wiring layers and no degradation of the step coverage occur; with the result that the disconnection of the second wiring layers in the through-holes are prevented. 
     According to the present invention, no disconnection of wire in the through-holes occurs even in the through-holes of diameter less than 1 micrometer, while in the prior art the disconnections of wires are indispensable for such small through-hole.

Abstract: A proximity effect correction method for electron beam lithography suitable for high voltages and/or very dense patterns applies both backscatter and forward scatter dose corrections. Backscatter dose corrections are determined by computing two matrices, a "Proximity Matrix" P and a "Fractional Density Matrix" F. The Proximity Matrix P is computed using known algorithms. The elements of the Fractional Density Matrix are the fractional shape coverage in a mesh of square cells which is superimposed on a pattern of interest. Then, a Dose Correction Matrix D is computed by convolving the P and F matrices. The final backscatter dose corrections are assigned to each shape either as area-weighted averages of the D matrix elements for all cells spanned by the shape, or by polynomial or other interpolation of the dose correction field defined by the D matrix. The D matrix also provides a basis for automatic shape fracturing for optimal proximity correction. Optionally, forward scattering correction may be included in the correction process. Forward scattering correction consists of boosting the dose applied to shape i by a factor b i . These boost factors are computed in a separate and independent step which considers only forward scattering. They are combined with those resulting from the backscatter correction scheme either by simple multiplication to form the final correction factors, or by inputting them to the backscatter correction scheme as numerical weights for each shape.
