METHOD OF DETERMINATION OF RESIDUAL SERVICE LIFE OF CATHODE-RAY TUBE Russian patent published in 1995 - IPC

Abstract RU 2028686 C1

FIELD: electronic devices. SUBSTANCE: at initial stage cathode is head to 900-1000 C for the course of half-time of cathode readiness. Then pressure of residual gases is found and after 30-50 s value of residual service life of cathode-ray tube is determined from relation given in description of invention. EFFECT: improved authenticity of prediction of service life of CRTs. 1 tbl
