In this mechanism the tape passes under six sensors that register electric contacts as the perforations pass.
In 1962 the British physicist Brian D. Josephson predicted that two superconducting objects placed in electric contact would display certain remarkable electromagnetic properties.
When two metals are placed in electric contact, electrons flow out of the one in which the electrons are less bound and into the other.
Owing to this unique combination of properties, it is used extensively as filaments for incandescent lamps, as electric contacts, and as electron emitters for electronic devices.
He suggests they continue their discussion, which they do during regular evening meetings characterized by theological discussions and increasingly electric contact — a fleeting touch, two hands roughly grasping shoulders, a garment grazing a breast.
In accordance with the combination of electric contacts thus established, relays control the action of the keys or of the bar that causes the spacebands to drop and, at the end of each line, the starting of the casting cycle.
But this would have been little more than a photocopier with re-usable paper an idea that had been tried before and had failed.Instead, Xerox is expected to pursue the idea of printing on Gyricon with a "magic wand"—a tool covered with an array of electric contacts and memory devices.
Modern multiple-units are increasingly fitted with automatic couplers that combine a draft function with connection of all power, braking, and other control circuits between two train-sets; this is achieved by automatic engagement, when couplers interlock, of a nest of electric contacts built into each coupler head.
The electric resistance per each electric contact is measured as 0.64 ± 0.29 Ω.
The bottom of the electrode rod is polished for best electric contact at every experiment.
In actual graphene-based electronic devices, gold is commonly used for electric contacts [6].
