MICROWAVE DEVICE FREQUENCY-CONTROL GEAR Russian patent published in 2007 - IPC H01J23/00 

Abstract SU 1840430 A1

FIELD: radio engineering; microwave devices, such as magnetrons, operating in several definite frequency channels.

SUBSTANCE: proposed microwave-device frequency control gear that has case, shaft with rod elastically attached thereto and coupled with control elements, and locking unit is characterized in that shaft is mounted within case for displacement along rod axis and is provided with two peripheral sections, each mounting disks whose butt-end surfaces are in contact with case and cylindrical ones, with one of two rods disposed within case in parallel with shaft axis on its either side; they protrude in opposite sides relative to case. One of disks mounts at least two stops disposed along shaft axis and provided with eccentric which can be set in rotary motion by section protruding relative to cylindrical surface of disk and engage one of rods at locking moment. Opposing disk whose cylindrical surface has at least two slots can be used as locking unit for engaging respective rod mounted within case.

EFFECT: simplified design, enhanced precision of adjustment to definite frequencies.
