PROCESS FOR MAKING PYROLYTIC GRAPHITE GRID ELECTRODES FOR ELECTRON TUBES |
| 摘要 |
A flat grid of pyrolytic graphite is obtained by cutting a disc from a cylindrical blank followed by deformation under pressure and by means of a partial vacuum. The grid is then machined and stretched within a stressing frame which also serves to mount the grid within the electron tube. |
