Claims Analysis
Total Claims: 4
Claim 1
Independent Claim
82 words
A VACUUM FLUORESCENT READOUT DEVICE COMPRISING; A SEALED ENVELOPE INCLUDING A CATHODE, AN ANODE, AND A PLURALITY OF CONTROL ELECTRODES; A FLAT INSULATOR POSITIONED BETWEEN THE CATHODE AND THE ANODE, SAID INSULATOR FORMED WITH A PLURALITY OF APERTURES FOR THE PASSAGE OF ELECTRONS FROM THE CATHODE TO THE ANODE; AND A FLUORESCENT MATERIAL DEPOSITED ON THE ANODE FOR GENERATION OF LIGHT WHEN ACTUATED BY ELECTRONS; SAID CONTROL ELECTRODES RESPECTIVELY POSITIONED ADJACENT TO SAID APERTURES FOR SELECTIVELY CONTROLLING THE PASSAGE OF ELECTRONS THERETHROUGH.
Claim 2
Dependent Claim
82 words
A VACUUM FLUORESCENT READOUT DEVICE COMPRISING; A SEALED ENVELOPE INCLUDING A CATHODE, AN ANODE, AND A PLURALITY OF CONTROL ELECTRODES; A FLAT INSULATOR POSITIONED BETWEEN THE CATHODE AND THE ANODE, SAID INSULATOR FORMED WITH A PLURALITY OF APERTURES FOR THE PASSAGE OF ELECTRONS FROM THE CATHODE TO THE ANODE; AND A FLUORESCENT MATERIAL DEPOSITED ON THE ANODE FOR GENERATION OF LIGHT WHEN ACTUATED BY ELECTRONS; SAID CONTROL ELECTRODES RESPECTIVELY POSITIONED ADJACENT TO SAID APERTURES FOR SELECTIVELY CONTROLLING THE PASSAGE OF ELECTRONS THERETHROUGH.
Claim 3
Dependent Claim
160 words
AN " AND" CIRCUIT COMPONENT FOR THE TRANSMISSION OF SIGNALS FROM A PLURALITY OF INPUT CIRCUITS TO AN OUTPUT CIRCUIT COMPRISING; A FIRST TRANSDUCER FOR CONVERTING ELECTRIC ENERGY INTO LIGHT ENERGY; A SECOND TRANSDUCER FOR CONVERTING LIGHT ENERGY INTO ELECTRIC ENERGY; SAID FIRST TRANSDUCER INCLUDING AN EVACUATED ENVELOPE CONTAINING AN ANODE, A CATHODE AND A PLURALITY OF CONTROL ELECTRODES; SAID ANODE COMPRISING A FLAT CONDUCTOR HAVING A PLURALITY OF SPACED OPENINGS FOR THE PASSAGE OF ELECTRONS; A FLUORESCENT MATERIAL DEPOSITED ON THE ANODE FOR GENERATION OF LIGHT WHEN ACTIVATED BY ELECTRONS; A FLAT INSULATOR POSITIONED BETWEEN THE CATHODE AND THE ANODE FORMED WITH A PLURALITY OF APERTURES FOR THE PASSAGE OF ELECTRONS FROM THE CATHODE TO THE ANODE; SAID CONTROL ELECTRODES RESPECTIVELY POSITIONED ADJACENT TO SAID APERTURES FOR SELECTIVELY CONTROLLING THE PASSAGE OF ELECTRONS THERETHROUGH; SAID INPUT TERMINALS CONNECTED TO SAID CONTROL ELECTRONS FOR THE APPLICATION OF CONTROL VOLTAGE PULSES; AND CONNECTIONS BETWEEN SAID SECOND TRANSDUCER AND THE OUTPUT TERMINALS.
