Exempel på hur man kan använda COLD-CATHODE i en mening

• 1958, a few hundred subscribers received dial service from June 1960 through January 1962 from the first mostly electronic system, that used cold-cathode electron tubes, instead of mechanical relays and switches.
• A cold-cathode vacuum tube does not rely on external heating of an electrode to provide thermionic emission of electrons.
• in Britain, and marketed through its Sumlock Comptometer division, they used vacuum tubes and cold-cathode switching tubes in their logic circuits and nixie tubes for their numerical displays.
• The krytron is a cold-cathode gas-filled tube intended for use as a very high-speed switch, somewhat similar to the thyratron.
• Three cold-cathode magnetron type density gauges (Redhead ionization gauges), each with its own high voltage supply and output electrometer, were flown to measure the density of the neutral atmosphere as a function of altitude, time, latitude, and solar and geomagnetic activity.
• Emitters are either of cold-cathode type, usually made of single crystal tungsten sharpened to a tip radius of about 100 nm, or of the Schottky type, in which thermionic emission is enhanced by barrier lowering in the presence of a high electric field.
