[Class 37] In a stacked metal rectifier, pressure is only applied to elements at points where the counter electrode is not in contact with the active layer,-e.g. selenium. In the example, Fig. 2, the counterelectrode 4 is applied to the selenium-coated base-plate 1 over an apertured washer 3, the effective part of the element being the central part. In Fig. 4, the selenium layer 2 is not present at the centre where insulating washers 5, 7 take the pressure. |
