    摘要: An interface circuit to the output of a programmable voltage ramp generator for decreasing the minimum voltage step of such a generator having two voltage channels and a minimum voltage step greater than 1 millivolt. The interface circuit receives an input from each of the two voltage channels (V.sub.2, V.sub.3), along with an inserted voltage (V.sub.1). The circuit includes a summing amplifier for (i) compressing the minimum voltage step from one voltage channel (V.sub.2) by a factor equal to or greater than such minimum voltage step, (ii) adding the voltage from the other channel (V.sub.3) to the compressed voltage, and (iii) subtracting the inserted voltage (V.sub.1) (or adding an inserted voltage which is negative). The inserted voltage (V.sub.1) is equal in magnitude to the maximum output value from the voltage channel that has the voltage compressed (V.sub.2). The output of the summing amplifier (V.sub.out) may be represented by:V.sub.out =(V.sub.3 /X)+(V.sub.2 /Y)+(V.sub.1 /Z)where X, Y, Z=attenuation or amplication factors. The interface circuit decreases the minimum voltage step at channel V.sub.2 by a factor Y down to a minimum voltage step of 1 millivolt or less.

    摘要: A register is disclosed in which an applied data signal D or its complement D is used to set or reset an output RS flip-flop under control of an applied load control signal L. The load control signal is applied to a switching circuit which controls application of the data signal D or D to the set or reset input of the output flip-flop such that the data signal is only applied for a time period sufficient to cause a change in state of the output flip-flop.

    摘要: Electronic components are welded or soldered or bonded to a support by arranging said components on the surface of the support and/or in holes piercing the support, in the presence of soldering materials having binding properties, and by then putting the thus-obtained assembly in contact with a perfluoropolyether in the liquid state, said perfluoropolyether having a temperature at least equal to that at which the soldering material develops its binding properties.
