Abstract

708,054. Semi-conductor devices. STANDARD TELEPHONES & CABLES, Ltd: June 8, 1951, Nos. 14736/50 and 20501/50. Class 37. The point contact electrode and semi-conductor body in a crystal rectifier device are embedded in a block of insulating thermosetting compound of the type claimed in one or more of the Specifications 518,057, 579,698, [both in Group IV], 629,111, 630,647, and 630,663, [all in Group IV(a)]. The insulating material is known as "Araldite" (Registered Trade Mark) adhesive resin or "Araldite" casting resin. In Fig. I, metal wires 3 and 4 penetrating ceramic discs 1 and 2, are fixed respectively to a tungsten, phosphor bronze or platinum alloy wire 7 and a germanium crystal 6. 'Araldite' casting resin is moulded around the whole, embedding the electrodes and forming a solid body or casing II. The assembly is then heated to harden the material. The ceramic discs may be replaced by metal discs, or the two wires may be formed with heads and no discs used, as shown in Fig. 5 . Identifying caps may be added. In Fig. 7 , an aluminium or nickel cup 23 is used to contain the 'Araldife' material. A disc or button contruction may also be used in which the two lead wires emerge from the same side of the disc. In Fig. 12, one lead wire 32 is provided with a spade portion to hold the crystal, and metal rings 35 and 3 6 are secured to the two lead wires to support the solid body 37 of 'Araldite' adhesive resin which is moulded around these elements, and then heated. The invention may also be applied to transistors. Specification 632,419, [Group XL(c)], also is referred to.
