.~.~> Electrode spacing related to mean free path length
DEFINITION
Classification: 313/605
Mean free-path spacing of envelope portions or content parts:
(under subclass 567) Subject matter wherein one envelope portion or a part of the device is spaced from another envelope portion or part of the device a distance which is less than the mean free-path length distance.
(1) Note. The mean free-path distance of an electron is the average distance an electron may travel in the gas or vapor without producing ionization of the gas or vapor. As the mean free-path length depends upon a number of factors, not all of which involve structure of the device, this and the indented subclass include patents which claim the parts as being within the mean free-path distance and include as cross references patents that disclose that the parts are within the mean free-path distance.
