Filed: 1973-03-07
Abstract: 1421222 Transistors WESTERN ELECTRIC CO Inc 7 March 1973 [13 March 1972] 11055/73 Heading H1K In a bipolar transistor comprising a base zone extending inward from one surface of a semiconductor body and within it an emitter zone, the graph of base dopant concentration versus depth exhibits two peaks with a minimum between them and the emitter junction is located between the peaks and preferably between the minimum and the deeper peak. The base zone doping may be effected before or after that of the emitter zone and is done in two stages, each of which creates one of the peaks. Though diffusion steps may be used to create the shallower peak and emitter zone it is preferred to use ion implantation for all doping steps. Typically, starting with an N type silicon wafer of not more than 0À01 ohm cm. resistivity carrying a 7 Á epitaxial layer of 0À1-10 ohm cm. resistivity an ion pervious silica layer is grown or deposited on the layer and an ion impervious photoresist mask apertured at the base zone site provided. Then in either order low and high energy boron ions are implanted to provide the base doping, the photoresist removed, and the wafer heated at 900‹ C. for ¢ hour to density the insulation and anneal bombardment damage. Then a window is formed in the insulation by photolithography and arsenic, antimony, or phosphorus implanted through it. A subsequent annealing at 1000‹ C. for ¢ hour relocates the emitter junction in the required position, and electrodes are provided by conventional methods. Details of ion energies and dosages are given. The transistors may form part of a batch or part of an integrated circuit in the wafer.

Title: Improvements relating to hydraulic-control valves
IPC: F15B9/09
Filed: 1950-05-05
Abstract: 694,315. Fluid-pressure servomotor-control systems. SPERRY CORPORATION. May 5, 1950 [May 11, 1949], No. 11178/50. Class 135 In a hydraulic control valve having a landed plunger slidable in a ported cylinder to control the supply and exhaust of high pressure liquid to or from a servomotor, the plunger is formed with unequal pressure areas at its ends, the smaller end being continuously supplied with low pressure liquid and the larger end alternatively connected to the low pressure supply and exhaust by the movement of a pilot piston valve slidable in a cylinder movable with the plunger to produce a pressure difference on the two ends to move the plunger. As shown for use in an electro-hydraulic servomotor control system for controlling a ship's rudder 3, Fig. 1, the valve 20 comprises a casing 25, Fig. 2, having connections 31, 32 to opposite ends of a servomotor 2, connections 34, 35 to a sump 17 and a connection 33 to a supply pump 18. A liner 26 having ports 36-40 communicating with the connections is secured in the casing and slidably mounts a plunger 30 having lands 41-44 and formed at one end with an extension 51 having an axial bore 52 slidably mounting a pilot piston valve 61 whose rod 16 is connected to an armature 14 mounted on spring supports 15. The armature 14 co-operates with a three-legged, servo-actuator 10, the outer legs 11, 12 of which are excited by an alternating current and the inner leg 13 connected through an amplifier 8 to the receiving rotor of a selsyn 4, 5 operable by a knob 1. The extension 51 is formed with a bore 57 communicating through a passage 59 and a pressure regulator 65 with the supply connection 33' to permit a constant supply of low pressure oil to the right-hand end of the plunger, a bore 56 communicating through a passage 54 with the left-hand end of the plunger, and a bore 60 communicating with the atmosphere. On rotation of the knob 1 to move the pilot valve 61 to the right, low pressure oil is supplied from the passage 59 to the left-hand end of the plunger 30 which thence moves to follow-up the movement of the piston valve and connect opposite ends of the servomotor to pump and sump respectively. On rotation of the knob 1 to move the pilot valve 61 to the left pressure oil acting on the left-hand end of the plunger is exhausted through the passage 54 and bores 56, 60 to move the plunger to the left to follow-up the movement of the piston valve and reverse the supply and exhaust connections to the servomotor. The pilot valve and plunger may if desired be operated by separate pressure fluids and the plunger 30 and its extension 51 continuously rotated to prevent sticking of the main and pilot valves.

IPC: H02K3/51
Filed: 1916-08-12
Abstract: 101,158. Allgemeine Elektricitõts- Ges. Aug. 6, 1915, [Convention date]. Coils and conductors; field magnets, dampers on poles of.-The bindings which secure the end connexions against centrifugal forces are not rigidly connected to the rotor body or associated parts, but are so mounted that the end connexions can move axially as a result of expansion of the windings due to heating. As shown in Figs. 2 and 4, the binding e is mounted on an annular metal support f with flanged rims; the support f bears upon the end connexions d, layers of insulation g and sheet metal h being interposed. The support f is slit at one or more places e<1>, so that it may contract on the end connexions, and gaps are left between the sides of the support and the rotor body b and fan-ring k. The support f may be constituted by a large number of segments with bent-up ends, and perforations for the passage of cooling-air may be formed in the support and in the layers g, h. For the purpose of damping or of asynchronous starting, the bindings may be utilized to short-circuit the slotclosing wedges at the ends, and the connecting- pieces l, Fig. 5, are made resilient to allow of axial movement of the binding. The connecting- pieces l may be formed as rings or as annular segments, the resiliency being increased by incisions.

Title: Apparatus for tensioning strip material such as a binding strap, wire or the like for binding boxes, bales, crates and other bodies
IPC: B65B13/30
Filed: 1938-04-13
Abstract: 514,625. Wire strainers. ABBOTT, G. J., and PACKERS SUPPLY CO. April 13, 1938, No. 11436. [Class 45] Relates to apparatus for tensioning strip material, which may be wire of elliptical cross section, for tensioning strapping such as used for binding barrels, bales &c. the tensioning being effected by members which grip the material during tensioning and separate after a given movement. The free end of the binding strip is inserted under clamps 9 and 10 and is then passed round the packet, under clamp 10 again and finally between the tensioning jaws 33 and 29. The clamps are then lowered to grip the strip against the base member 1 by rocking levers 11 and 12. The tensioning jaw 29 is formed in a member 24 pivoted at 23 to the body 2 of the apparatus, whilst the jaw 32 is formed at the end of an operating lever 36 pivoted at 31 to the member 24 carrying the jaw 29. The normal position of the parts is that shown in Figs. 1 and 5, the jaws opening under gravity for insertion of the strip. In operation, lever 32 is swung counterclockwise to cause the jaws to travel from left to right along the strip. The movement of the lever 32 is then reversed so that the jaws close on the strip (Fig. 10) and tension it until finally the lever engages a fixed abutment 37 on the body 2 which acts as a fulcrum so that with slight further movement the jaws open to release the strip. The operation is then repeated until the required tension is produced. The clamp 10 allows the strip to pass freely in the tensioning direction but prevents movement in the reverse direction when the grip of the tensioning jaws is relaxed. The short tensioning stroke of the jaws, limited by the engagement of the lever 32 with the fulcrum 37, prevents undue bending of the unused end 21 of the strip. The face of jaw 33 is smooth and is given a large radius of curvature to which the length of the strip is tangential, for the same reason. The cutting of the strip and joining of the overlapping ends is effected by depressing a handle 55. The shaft of this handle carries a cam 53 which lowers a sliding die 44 against a fixed die 4 formed in a channel 3 in the base 1. The co-operating faces of the dies are so shaped as to pass a V-ridge 38, Fig. 16, upwardly out of the overlapping ends 18, 19 of the strap. At the same time eccentric portion 54 in the handle shaft lowers sliding frames 57 carrying punches 60 which press out tongues 41 from the overlapping ends of the straps to join them together. The punches 60 are arranged in two rows and their extent of projection increases along the rows so that the tongues are pressed out in succession along the joint. The die 44 has a cutting edge at one end co-operating with a fixed cutting edge 51 to sever the strip.
