| 21. | Cold cathode lamps are generally less efficient than thermionic emission lamps because the cathode fall voltage is much higher.
|
| 22. | A "'Nixie tube "'( ), or cold cathode display, is an displaying numerals or other information using glow discharge.
|
| 23. | As for the inverter circuit of a cold cathode fluorescent lamp, a resonance type circuit has been widely used.
|
| 24. | Hot cathodes typically achieve much higher power density than cold cathodes, emitting significantly more electrons from the same surface area.
|
| 25. | I am planning to make a smallish breadboard-mounted mechanism which can be used to power a cold cathode florescent backlight.
|
| 26. | Cold cathodes rely on field electron emission or secondary electron emission from positive ion bombardment and do not require heating.
|
| 27. | The first electronic ignition ( a cold cathode type ) was tested in 1948 by hemis in 1963 and 1964.
|
| 28. | The principle behind cold cathode version is the same, except that electrons are produced in the discharge of a high voltage.
|
| 29. | The Cold Cathode Gauge Experiment ( CCGE ) which was part of the ALSEP on Apollo 13 was never flown again.
|
| 30. | A "'CCFL inverter "'is an electrical inverter that supplies alternating current power to a cold cathode fluorescent lamp ( CCFL ).
