HERMETIC HOUSING FOR HIGH-VACUUM PRECISE INSTRUMENT AND METHOD FOR ITS MANUFACTURING Russian patent published in 2009 - IPC H01L21/48 

FIELD: electricity.

SUBSTANCE: invention is attributed to radio and electric engineering and can be used in design and manufacture of precise high-vacuum instruments in air-cosmic and radio engineering industries. Hermetic housing for high-vacuum precise instrument contains casing, ring ceramic socket with single and coaxial sealed lead-outs impermeably connected along perimetre with casing and exhaust tabulation impermeably connected with socket. In this device socket contains along its diametre the compensating ring made of "68НХВТЮ-ВИ" alloy, which ring is tacked using laser bonding and connected with casing and socket. Exhaust tabulation contains two equalising subs made of "68НХВТЮ-ВИ" alloy and "12Х18Н10Т-ИД" stainless steel mounted at its butt ends and tacked using laser bonding and impermeably connected with tabulation. Also the method for above mentioned device execution is suggested.

EFFECT: improvement of manufacturing quality and providing high technological and operation properties of hermetic housing, application field expansion.
