Class Information
Number: 315/39.3
Name: Electric lamp and discharge devices: systems > Combined load device or load device temperature modifying means and electrical circuit device structure > Discharge device load with distributed parameter-type transmission line (e.g., wave-guide, coaxial cable) > Traveling wave type with delay-type transmission line
Description: Subject matter in which the transmission line with distributed parameters incorporated in the tube structure is arranged to propagate a traveling electro-magnetic wave and is constructed and arranged to have a wave component the velocity of which is reduced in comparison with the wave velocity in free space; and in conjunction therewith are means for generating an electron stream whose path is in proximity to the path of said traveling wave component so as to permit an exchange of energy between the electron stream and the traveling wave propagated along the transmission path.
