Claims Analysis
Total Claims: 4
Claim 1
Independent Claim
69 words
A METHOD OF MANUFACTURING A PHOTOSENSITIVE DEVICE COMPRISING THE STEPS, APPLYING TO PROTIONS OF A SUPPORT A LAYER CONSISTING ESSENTIALLY OF LEAD MONOXIDE, BIASING SELECTED AREAS OF SAID LAYER OF LEAD MONOXIDE NEGATIVELY TO EFFECT AN ELECTRICAL DISCHARGE THROUGH AN ATMOSPHERE CONTAINING OXYGEN AT A PRESSURE OF ABOUT 4000 TO 600X10-**5MM. HG TO FORM OXYGEN IONS WHICH BOMBARD SAID AREAS AND INTRODUCE OXYGEN INTO THE LAYER AT SAID AREAS.
