Abstract

PURPOSE:To enable a metal cylinder to absorb sufficiently and relieve thermal strain, by separating the electrical connection part from the airtight sealing part as to the airtight window for vacuum-sealing the input-output waveguide of electron tubes of microwave and milliwave bands. CONSTITUTION:Ceramic disc 2 is brazed to flange 1a for brazing the ceramic disc of thin metal cylinder 1, and tip part 14 of metal cylinder 1 is set into and brazed to the external circumference of protruding square waveguide part 10 through shrinkage fitting. Then, rectangular conversion flange 11 is composed of protruding rectangular waveguide part 10, reinforcing culinder part 9a, and sideboard 9.
