Claims Analysis
Total Claims: 5
Claim 1
Independent Claim
54 words
A method of introducing getter material into a cavity in a ring laser gyro comprising steps; evacuating said cavity flashing the getter material outside the evacuated cavity; forming a beam of getter atoms from said flashed getter material directed toward a predetermined region in said evacuated cavity; depositing said getter atoms on said region.
Claim 2
Independent Claim
54 words
A method of introducing getter material into a cavity in a ring laser gyro comprising steps; evacuating said cavity flashing the getter material outside the evacuated cavity; forming a beam of getter atoms from said flashed getter material directed toward a predetermined region in said evacuated cavity; depositing said getter atoms on said region.
Claim 3
Dependent Claim
23 words
The method of introducing getter material as in claim 1 including the further step of reflashing said getter material deposited on said region.
Claim 4
Independent Claim
52 words
A method of introducing getter material into a cavity comprising steps: evacuating said cavity; flashing the getter material outside of said evacuated cavity; forming a beam of getter atoms from said flashed getter material; directing said beam toward a predetermined region in said evacuated cavity; depositing said getter atoms on said region.
Claim 5
Independent Claim
52 words
A method of introducing getter material into a cavity comprising steps: evacuating said cavity; flashing the getter material outside of said evacuated cavity; forming a beam of getter atoms from said flashed getter material; directing said beam toward a predetermined region in said evacuated cavity; depositing said getter atoms on said region.
