Abstract
Abstract The hybrid rectifier includes a structurally parallel arrangement of field effect emitters and collector surfaces. Each respective emitter-collector section may be spaced apart a preselected distance to control the current density in that section. Current density in each section is also a function of the individual emitter pin sizes and geometry. This results in a device which may contain many individual sections having separate and distinct characteristics and thereby providing a multifunction hybrid rectifier.

Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
139 words
A hybrid rectifier comprising: plural parallel collector plates, plural parallel electron emitter plates disposed respectively between said plural collector plates and parallel therewith, voltage means coupled to respective of said emitter and collector plates for coupling a potential thereacross and thereby developing an electric field therebetween, said emitter plates having first and second emitting surfaces for conducting electrons simultaneously from opposing faces thereof toward respective first and second collectors in response to an electric field developed therebetween, each of said emitter plates comprise a conductive sheet sandwiched between said emitting surfaces for electrically coupling said potential thereto, and each of said emitting surfaces comprises a field-effect electron emitter having a plurality of uniformly spaced parallel emitting pins disposed normal to said conductive sheet and an oxide metal insulator disposed between adjacent pins for insulating, encompassing, and supporting said pins.
Claim 2
Dependent Claim
139 words

Claim 3
Dependent Claim
35 words
A hybrid rectifier as set forth in claim 1 wherein respective collector plates are spatially disposed separate and distinct distances from emitting surfaces of said emitter plates for operating in electric fields of differing strengths.
Claim 4
Dependent Claim
35 words

Claim 5
Dependent Claim
56 words
A hybrid rectifier as set forth in claim 1 wherein each of said field-effect electron emitter surfaces have different emitting pin density per unit area with respect to other emitter surfaces providing selectable voltage ranges of field-effect emission, said emitting pins having a minimum density of one million emitting pins per square centimeter of surface area.
Claim 6
Dependent Claim
30 words
A hybrid rectifier as set forth in claim 4 wherein insulator spacers are disposed between adjacent emitter and collector plates for providing selected spatial separation therebetween to control field-effect emission.
Claim 7
Dependent Claim
29 words
A hybrid rectifier as set forth in claim 1 wherein insulator spacers are disposed between adjacent emitter and collector plates for providing selected separation therebetween to control field-effect emission.
