Title: Manufacture of cathode structure of magnetron
Inventor: SAWACHI KAZUICHI
IPC: H01J9/04
Filed: 1990-02-09
Abstract: PURPOSE:To improve the coupling strength of an end shield and a cathode supporting bar by fitting a cathode supporting bar, made of a wire drawing material, in a press molding, and filling molybdenum powder,m to be formed into an end shield, for press molding, and thereafter, sintering them to be unified. CONSTITUTION:A cathode supporting bar 5 is made of a wire drawing material. This cathode supporting bar 5 is installed to a press metal mold not shown by a figure, and the molybdenum powder to be formed into an end shield 2 is filled in the press metal mold, and press molding is performed so that the tip 5a of the cathode supporting bar 5 is buried, and thereafter, they are sintered to be unified. Consequently, the tip 5a of the cathode supporting bar 5 is buried thoroughly in the end shield 2 without recrystallization of the molybdenum, and a passing area of the current is increased remarkably in comparison with the conventional weldment. Furthermore, since the cathode supporting bar 5 is buried in the end shield 2, the secure strength can be kept after the assembly into magnetron. Fragility to be caused by recrystallization of members is thereby prevented, and the coupling strength of the end shield and the cathode supporting bar is improved remarkably.

IPC: G03C3/00
Filed: 1999-02-05
Abstract: PROBLEM TO BE SOLVED: To provide a waterproof case equipped with a reliable pressure adjusting valve while realizing space saving and cost reduction. SOLUTION: In this waterproof case, an aperture 70 is formed on a case main body 48 and a projection 71 projecting toward the outside of the main body 48 is arranged in the aperture 70. A vent hole 12 is formed at a position where elastomer 49 laminated on the outside of the main body 48 abuts on the projection 71. When pressure gets high in the waterproof case, the thin part 74 of the elastomer 49 is pressed through the aperture 70 and deformed to be swollen outward. Thus, the aperture 70 communicates with the vent hole 12 so that contained gas is discharged.
