Abstract
877,421. Crystal diodes; assemblies of components. PHILIPS ELECTRICAL INDUSTRIES Ltd. April 28, 1958 [May 1, 1957], No. 13395/58. Class 37. A diode in a vacuum-tight envelope is provided with a shunt resistor on or in the envelope itself so as to equalize the back voltage across each of a number of the diodes connected in series. The resistance may take the form as shown in Fig. 1 of a resistive layer 13 across the insulator 10 forming part of the envelope of the diode comprising N-type germanium plate 7 and indium electrode 8, the remainder of the envelope being formed by metallic base 1 and cover 2. In the embodiment shown in Fig. 2 the resistive layer 22 is formed over the surface of an insulating material 21 in which the diode similar to that in Fig. 1 is embedded. In Fig. 3 the insulating material incorporated in the envelope to isolate the connections to the diode forms the resistance either by virtue of a slight conductivity imparted to the material itself e.g. by the addition of carbon to a ceramic material, or by a resistance layer on the surface.
