Abstract

An improved method for manufacturing a field emission structure is provided that involves receiving magnets from a magnet supplying device and placing each one of the magnets at a corresponding location of a plurality of location of the field emission structure. The corresponding location and a corresponding orientation of each of the magnets relative to each other are defined in accordance with a code.

Claims

1. A method for manufacturing a field emission structure, comprising the steps of:

receiving a plurality of magnets from a magnet supplying device;

placing each one of said plurality of magnets at a corresponding location of a plurality of locations of said field emission structure, said corresponding location and a corresponding polarity orientation of each of said plurality of magnets relative to each other being defined in accordance with a code that specifies at least one magnet of said plurality of magnets having a first polarity orientation and at least one magnet of said plurality of magnets having a second polarity orientation, said second polarity orientation being different from said first polarity orientation, wherein adjacent magnets of said plurality of magnets that have been placed at two adjacent locations of said plurality of locations of said field emission structure both have said first polarity orientation and produce a repel force, said repel force requiring a holding force to maintain said first polarity orientation of said adjacent magnets and

applying the holding force to said field emission structure.

2. The method of claim 1, wherein said code has correlation properties corresponding to a spatial force function.

3. The method of claim 1, further comprising the step of:

putting the field emission structure under pressure to provide the holding force to maintain said polarity orientations of said plurality of magnets.

4. The method of claim 1, wherein each of said plurality of magnets is received from said magnet supplying device are placed at a corresponding location individually.

5. The method of claim 1, wherein two or more of said plurality of magnets are received from said magnet supplying device and placed at corresponding locations as a group.

6. A method for manufacturing a field emission structure, comprising the steps of:

receiving a plurality of magnets from a magnet supplying device; and

placing each one of said plurality of magnets at a corresponding location of a plurality of locations of said field emission structure, said corresponding location and a corresponding orientation of each of said plurality of magnets relative to each other being defined in accordance with a code wherein said plurality of locations of said field emission structure corresponds to the locations of a plurality of holes in one of a support frame or a substrate.

7. The method of claim 6, further comprises affixing at least one of said plurality of magnets to said frame using a bolt and nut.

8. The method of claim 6, wherein the step of placing comprises screwing said at least one magnet of said plurality of magnets into one of said plurality of holes in said support frame.

9. The method of claim 6, wherein the step of placing comprise heating said substrate to fuse said plurality of magnets to said substrate.

10. The method of claim 6, wherein said plurality of magnets is affixed using one of a bolt, a nut, a screw, an adhesive, or a fixative.

11. A method for manufacturing a field emission structure, comprising the steps of:

receiving a magnet from a magnet supplying device; and

affixing the magnet at a corresponding location of a plurality locations of said field emission structure, said corresponding location and a corresponding polarity orientation being defined in accordance with a code, said magnet having a first polarity orientation and at least one other magnet affixed at another location of said plurality of locations of said field emission structure having a second polarity orientation that is different from said first polarity orientation, wherein adjacent magnets both have said first polarity orientation and produce a repel force, said repel force requiring a holding force to maintain said first polarity orientation of said adjacent magnets.

12. The method of claim 11, wherein said code has correlation properties corresponding to a spatial force function.
