<p>930,704. Circuit assemblies. SONY CORPORATION. Aug. 25, 1961 [Sept. 5, 1960], No. 30713/61. Class 37. An Esaki diode pair comprises a pair of conductive strips 2a, 2b insulated from each other and a pair of Esaki diodes 4a, 4b disposed, with opposite polarities, one on each of the conductive strips and having one set of terminals electrically connected therewith, a bridging conductive plate 5 connecting the other set of terminals of the diode pair, an insulating layer 8 laid on the conductive strips 2a, 2b and a second conductive plate 7 electrically connected to the bridging conductive plate 5 so as to form two variable capacitors 12a, 12b, the capacitances of which may be varied by sliding the conductive plate 7 in order to alter the area of the plates. The equivalent circuit of the diode pair is as shown in Fig. 2 wherein the conductive strips 2a, 2b form terminals 10a, 10b, a conductive strip 1, upon which the strips 2a, 2b are mounted but insulated therefrom, an earth point 13 and the bridging plate 5, terminal 11, capacitors 12a, 12b being formed between conductive strips 2a, 2b and plate 7. The conductive plate 7 is held in position by an elastic tongue 9 projecting from the plate 5. A plurality of Esaki diode pairs may be mounted on the plate 1, Fig. 3 (not shown), and also pairs may be mounted on opposite surfaces of this plate, Fig. 4 (not shown). The conductive plate 7 may be dispensed with and in its place tongue 9 or plate 5 may form one of the capacitor plates.</p> |
