Abstract
The internal "feed-back" from plate to grid of a pliotron is prevented by electrostatically shielding the two from each other. Specially designed tubes, thus shielded, are described. The capacity between plate and control grid was found to be only.006μμF in the best models. These tubes may, therefore, be expected to behave as strictly unidirectional devices at all frequencies, which was found to be true. Plate-resistance characteristics are given, and it is shown that the internal plate conductance is negligible compared with the conductance of practical circuits. The plate current thus depends on grid voltage only, i.e., in place of the seven parameters of the three element tube there is but one, mutual conductance.
