732,605. Semiconductor rectifiers. STANDARD TELEPHONES & CABLES, Ltd. May 15, 1953 [June 27, 1952], No. 13660/53. Class 37. In a crystal diode, the element and electrode are mounted on plugs of polygonal cross-section which are held in an insulated tube by their sharp edges engaging rings attached to the tube. In Fig. 1, the brass rings 2, 2<1> are pushed into the open ends of ceramic tube 1 and rods 3, 3<1> of square cross-section are driven through the centres of rings 2. 2<1>. Rods 3, 3<1> carry the crystal 5 of germanium, silicon or other semiconductor and the whisker electrode 4. Sealing is effected by moulding compound or cement 9, 91. The spaces 6 between rods 3 and tubes 2 enables the crystal cavity to be filled with a suitable compound to render the electrode assembly shock-proof. A large wafer of germanium may be soldered in one operation to the end surfaces of a bunch of rods 3, and then cut so that the rods may be separated, each bearing its portion of germanium. |
