A semi-conductor device comprises a body of P-type conductivity comprising binary compounds having elements selected one from each of columns III and V of the Periodic Table, e.g. the phosphides, arsenides and antimonides of aluminium, gallium and indium, and a rectifying electrode consisting of tin telluride or a mixture of tin telluride and tin. The excess of tin may be increased up to a mixture containing 3 mols. of tin to each mol. of tin telluride, a preferred mixture, which melts at about 700 C., containing 40% by weight tin telluride and 60% by weight tin. In one example, a diode is formed by alloying a pellet of tin telluride with the surface of a wafer of P-type indium phosphide. The alloying is carried out in an inert atmosphere within a temperature range varying from the melting-point of the pellet to just below the melting-point of the wafer, a preferred temperature being 800 C. The surface of the wafer is afterwards cleaned in a mixture of concentrated nitric and hydrochloric acids. An ohmic electrode may be formed by alloying zinc or cadmium into the surface of the body. In a further example a transistor is formed by alloying to opposite surfaces of a wafer of P-type gallium arsenide pellets consisting of the preferred mixture referred to above. The alloying is carried out at 800 C. in a reducing atmosphere. The junctions formed are of unequal size. A base tab consisting of, e.g., nickel or nickel alloys such as fernico or " Kovar " (Registered Trade Mark) is soldered to the wafer with, e.g. cadmium. The wafer is then etched as before.

Title: Speed control system for centrifuge motors and the like
IPC: H02P25/14
Filed: 1964-09-22
Abstract: 1,079,525. Automatic speed control. IVAN SORVALL, Inc. Sept. 22, 1964 [Sept. 23, 1963], No.38678/64. Heading G3R. [Also in Division H2] A series motor 33, which drives a centrifuge, is energized through saturable reactor 44, a thyratron T being fully conductive when the motor is first switched on so that the impedance of reactor 44 is at a minimum. When the rectified voltage across resistor R5 approaches equality with the reference potential selected by potentiometer R6 the impedance of reactor 44 is increased to limit the motor speed to the preselected value. A closed feedback loop circuit is formed comprising tachometer generator 56, control unit 29, and the reactor. The motor is braked by supplying field windings L3, L4, with direct-current and connecting resistor R1 across armature 34. Zener diodes D6, D8, fix the potentials at the ends of potentiometer R6 despite changes in the supply voltage. The thyratron T is fully conductive until the potential at line 86 becomes negative due to the tachometer signal exceeding the reference signal. Diode D9 then conducts and overcomes the positive bias supplied through resistor R7. A switch S1 is positioned in accordance with the high or low value of the supply voltage. When the switch S1 is in the low-voltage position, an autotransformer 24 steps up the potential at line 18 for the motor drive. Tachometer 56 is connected to speed-indicating voltmeter 62 associated with over-speed relay L12 controlling contacts S7 in circuit with main contactor 36. Automatic time programming is provided by contacts 63 of control clock 64. The thyratron T may be replaced by a silicon controlled rectifier. A transistor conducts in response to an error signal and delivers a positive pulse to a capacitor which charges to a voltage determined by the breakdown value of a diode. When this diode breaks down, the gate of the silicon controlled rectifier is triggered. As the motor speed approaches the desired value, the time required for charging the capacitor to the point of breakdown of the diode is increased, Fig.6 (not shown).
