摘要： A turbomolecular vacuum pump utilizes a virtually zero power magnetic bearing assembly with a single axis sevo control and has an optimized L/D ratio and an optimized number of pole faces. In such a structure, radial stiffness is low and radial damping is high so that single axis control is possible. A frusto-conical mechanical bearing structure is shown as a fail-safe back-up for the magnetic suspension system taught.

摘要： A CONDUCTIVE METAL STRIP FOR ALKALINE BATTERIES CARRIES AN EFFECTIVELY ORDERED ARRAY OF EXTREMELY THIN, SQUARE NICKEL (OR NICKEL PLATED IRON) FLAKES STACKED APPROXIMATELY NORMAL TO AND TRANSVERSELY OF THE STRIP WITH THEIR EDGES APPROXIMATELY PARALLEL, AND WITH ONE EDGE OF EACH FLAKE CONDUCTIVELY JOINED TO THE STRIP BY A SINTERED NICKEL FILLET. THE FLAKES ARE SLIGHTLY SEPARATED BY THE MODE OF FABRICATION AND BY DEVIATIONS FROM EXACTLY NORMAL AND TRANSVERSE POSITION ON THE STRIP, AND FROM EXACT FLATNESS. THESE DEVIATIONS ARE SO SMALL AS COMPARED TO THE GENERALLY NORMAL AND TRANSVERSE POSITIONS AND THE FLATNESS OF THE FLAKES, THAT THEY PROVIDE ESSENTIALLY REGULAR INTERSTICES WITH OPTIMAL SURFACE AREA OF ACTIVE MATERIAL AND ACCESSIBILITY THEREOF TO ELECTROLYTE, AND MINIMAL VOLUME AND CONDUCTIVE LENGTH OF SUPPORTING MATERIAL. A SUITABLE TECHNIQUE OF FABRICATING A FLOCKED STRIP BY WAY OF MAGNETIC STACKING OF FLAKES ON BELTS AND FINALLY ON THE STRIP, TRAVELING AT DIFFERENT SPEEDS, IS DESCRIBED.

摘要： Electronic circuits containing an admittance element produce at a pair of input terminals an equivalent impedance having an admittance term inversely related to the admittance element. The circuits are suitable for miniaturization techniques, and permit electronically simulated inductances of large values to be created with capacitive elements. The admittance inverting circuits are of two kinds: one produces an equivalent impedance which appears as a resistance paralleling said inverted admittance; the other has an equivalent impedance which appears as a resistance in series with said inverted admittance. Both circuits have the admittance element connected in circuit with first and second resistances and with isolating amplifier means causing one of the parameters of current or voltage in one of said resistances to appear at the circuit''s input terminals. In the circuit having a parallel equivalent impedance, the first resistance is in series with the admittance element, and these two are paralleled by said second resistance. An operational amplifier has the admittance element connected between input and output, so that the circuit''s input terminals see the voltage developed across the first resistance. In the circuit producing a series equivalent impedance, the admittance element is paralleled by the second resistance, and the two are in series with the first resistance. Two or more emitter follower amplifiers are connected to cause the current through the second resistance to be the current through the input terminals.
