Abstract: Miniaturized variable resistors of the circular type having a drive wheel rotatable in a housing and an arcuate resistance element slidably engaged by a contact driven by the drive wheel. The drive wheel has a rim thicker than the web of the wheel and substantial portions of the resistance element are located within the rim to provide an ultrathin potentiometer.

Abstract: AN ILLUSTRATIVE EMBODIMENT OF THE DISCLOSURE DISCLOSES A PHANO-CONCAVE WAFER OF CHANNEL ELECTRON MULTIPLIERS IN AN ELECTRON-OPTICAL SYSTEM THAT PRODUCES INVERTED AND INTENSIFIED IMAGES OF FAINTLY ILLUMINATED OBJECTS. THE INDIVIDUAL CHANNELS ARE RELATIVELY SHORT AT THE CENTER OF THE WAFER AND GRADUALLY INCREASE LENGTH TOWARD THE PERIPHERY IN ORDER TO PRODUCE THE CONCAVE EQUIPOTENTIAL

SURFACE NEEDED FOR ELECTRON IMAGE INVERSION. THE RESPECTIVE CHANNEL DIAMETERS AND VARIED IN ACCORDANCE WITH EACH CHANNEL LENGTH TO MAINTAIN A GENERALLY CONSTANT RATIO OF LENGTH TO DIAMETER AND THE ASSOCIATED ELECTRON GAIN FOR ALL OF THE CHANNELS IN THE WAFER.
