Title:
マグネトロン
Document Type and Number:
Japanese Patent JP5201711
Kind Code:
B2
Abstract:
A gap is provided between a cooling block 22 and a magnetic yoke 20. A cushioning material 25 is interposed in the gap to fix the cooling block 22 relatively to the magnetic yoke 20 by screws. Thus, even when metals having a large difference in tendency of ionization are used in the cooling block 22 and the magnetic yoke 20, the corrosion of the metals hardly arises. Further, the cushioning material 25 is provided in the gap between the cooling block 22 and the magnetic yoke 20, so that an impact or vibration to an anode tubular member 10 can be mitigated and the disconnection and deficiency of the filament of a cathode structural member can be reduced. Further, since a dimensional unevenness of the cooling block 22 or the magnetic yoke 20 can be absorbed by the cushioning material 25, the dimensional accuracy of parts does not need to be improved to make an assembly easy.
