Title: Improvements in or relating to semiconductor devices
IPC: H01L45/00
Filed: 1965-03-23
Abstract: 1,060,505. Semi-conductor devices. NIPPON TELEGRAPH & TELEPHONE PUBLIC CORPORATION. March 23, 1965 [March 25, 1964], No. 12198/65. Heading H1K. A layer less than 10Á thick of a semi-conductor having a resistivity between l0<SP>3</SP> and 10<SP>10</SP> Q cm.-e.g. pure gallium arsenide, cadmium selenide or silicon-has a symmetrical but non- linear voltage-current characteristic, exhibiting negative resistance for both positive and negative voltages. The characteristic (Fig. 1, not shown) has the same general form as that of a discharge tube, but with the ratio of the breakdown voltage to the discharge-sustaining voltage being of the order of 100 : 1. The speed of transition between the discharging and non- discharging states is high, switching times being less than 10-8 sec. The effect is little dependent on temperature and is exhibited at room temperatures. The value of the breakdown voltage is, however, affected by illuminating the device so that it can be used as a light-operated switch. It can also have divided electrodes, thus constituting a plurality of switching devices in a single body suitable for integrated circuitry. The preferred form consists of a molybdenum electrode on which gallium arsenide is deposited from the vapour phase and then surmounted by a counter electrode of tellurium also deposited by evaporation. Alternative electrode materials specified are platinum, titanium, tungsten and degenerate semi-conductors. It is also possible to use non-bonded plate electrodes or point contact electrodes, bonded or unbonded.

Title: Improvements in or relating to systems for energizing electrical precipitators
IPC: H02M1/20
Filed: 1951-05-28
Abstract: 693,404. A.C. motors. RESEARCH CORPORATION. May 28, 1951 [June 14, 1950], No. 12459/51. Class 35. A squirrel-cage motor for driving a rotary rectifying switch for electrostatic precipitators is rendered synchronous by means of permanent magnets on the squirrel cage member. In one form, Fig. 2, the squirrel cage rotor 31 has longitudinal salient poles 56, 57, 58, 59 on its periphery, each of these poles carrying permanent magnets 49, 52. In an alternative form, the rotor is wound and the squirrel cage stator carries the salient poles and permanent magnets. In a modification, Fig. 3, the squirrel cage rotor carries polepieces 56, 57, 58, 59 without permanent magnets, the correctlyphased synchronization being ensured by a permanent magnet rotor 60 influenced by the same stator. In a further modification separate stators with separate windings are used for the squirrel cage and permanently magnetized rotors. Alternatively either or both of the squirrel cage or permanent magnet members may be stationary while the armature windings rotate. Circuits are described for energizing the squirrel-cage section independently of the permanently magnetized section which may be connected to the supply manually or automatically after a time interval, in response to a predetermined voltage generated by the permanent magnet section, or by a centrifugal switch. The permanent magnet section may be de-energized when the motor is synchronized.

Abstract: 284,903. Betz, P., and Wulf, H. May 10, 1927. Cased forms; tubes.-Paper, tarred cardboard, or like tubes are encased by metal tubes to form electric insulating tubes &c. by drawing a flat metal strip together with the paper &c. through a die by means of driven rollers so as to bend the strip to U-form, the rollers serving also to bend the edges of the strip to form a lock seam. The paper &c. tube is inserted in a two-part die 4 through which it is drawn by rolls a, b, together with the metal strip 2 from a reel 1. The die bends the strip into the form shown at 6, the upper portion of the die being shaped as shown in Fig. 13 and the lower part as shown in Fig. 12. The rolls a, b compress the casing on the paper &c. tube and co-operate with a fixed die 7 or roller to bend over one edge of the metal at 8. This edge is further bent at 10 by a roller 9. Rolls c, d then compress the edges as shown at 11 and rollers e - - h bend over the seam as shown at 12 and 13, the seam being finally pressed down as shown at 14 by rollers i<1>. The rolls a, b and c, d, are driven by worm gearing and the rolls e h may be freely rotatable or may be driven. Tubes other than those of circular cross-section may also be encased in this manner.

A bolt D is passed centrally through the cups to lock the parts together in a detachable manner. This arrangement relieves the bolt of the shear strains due to the longitudinal stresses in the members of the framework. To prevent rotation of the jointed members about the bolt D, they may each be provided with two depressions, as shown in Fig. 4. Strengthening liners are preferably inserted in the tube ends prior to flattening.

Abstract: 130,771. Marks, E. C. R., (Rockwood Sprinkler Co.). Aug. 8, 1918. Capsules, caps, and like cupped articles.-Hol- .low metal articles such as containers or caps, are formed with cylindrical insides and with conical exteriors which thicken towards the upper open ends of the shells, flanges being formed in their upper ends if desired by upsetting the conically formed member in a conical die 71, Fig. 9, which is shaped to receive the formed cup a<6>. The blanks a to be formed are first shaped by a series of plungers as 12 - - 52, and corresponding dies 10, 50, of decreasing sizes, which form a cup as a<4>, Fig. 6, having a slightly thickened upper part. The cup a<4> is then treated in a drawing press, Fig. 7, being forced by a plunger 57 formed with a thickened lower end, and with a recess 58 which forms a shoulder on the cup a<5>, which is stripped from the plunger by a stripper 64 carried by a plate 62 acted on by springs 61 which move the plate 62 over guide bolts 60 until arrested by nuts 63. As the plunger 57 ascends, it draws out the metal and forms a true cylindrical surface inside the cup a<5>. The final shaping of the cup is effected in a die 71, Fig. 9, which is conical, and is formed with an annular recess 72 in its upper part. The metal is pressed into this recess by a die 77 which upsets the metal in a longitudinal direction. The plunger 73 is arranged in a recess in the press head, and is normally pressed downwards by a strong spring 81 acting on a plate 79 which abuts on a shoulder on the plunger 73. Vent holes 66, 84, 85, 86 are formed in the plungers and dies. A screw thread may be formed on the top flange of the finished article.
