Abstract: 1,249,317. Semi-conductor resistors. MULLARD Ltd. 19 Nov., 1968, No. 54878/68. Headings H1K and H1S. In a semi-conductor resistor comprising a body containing electrically active impurities to provide free charge carriers and electrically inactive impurities to reduce the temperature coefficient, the inactive impurities consist for a substantial part of neutral impurities. The neutral impurities may be elements such as Pb or Sn in Si, Ge or a mixed crystal of Si or Ge, or Al in GaAs. Alternatively the semi-conductor may contain a normally active impurity introduced in such a concentration and in such a way that a proportion of the atoms act as neutral impurities. Crystal dislocations produced by electron bombardment may also be used as neutral impurities. The resistor may be integrated in a wafer together with other devices such as transistors. In a first method an N-type Si wafer is provided with an oxide mask exposing a strip which is to form the resistor with an enlarged contact region at each end. Sn is diffused into the exposed area from the gas phase followed by a drive-in step. Boron is then diffused-in to form a P-type region. The wafer is then reoxidized, the contact regions are exposed and are provided with Al contacts to which conductors may be connected. In a second method an N-type Si wafer is provided with an oxide mask exposing contact areas for the resistor. B is diffused-in to form the contact regions and the resistor strip is exposed. Al is vapour deposited and processed to form contacts to the major portions of the contact regions. Ga<SP>69</SP> is then introduced into the resistor strip and also the non-contacted parts of the contact regions by ion implantation. The wafer is then annealed. A proportion of the implanted ions act as active impurities to provide the current carriers and the remainder act as neutral impurities. In a modification, after deposition of the Al layer the resistor strip is exposed by etching away the Al and oxide layers. Ga is then ion-implanted and the excess Al is etched away leaving the contact lands. In a further method an N-type Si wafer is provided with an oxide mask exposing contact lands for the resistor. B is diffused-in to form the contact regions, the oxide layer is removed and the wafer is reoxidized. Smaller apertures are formed in the oxide layer over the contact regions, Al is vapour deposited and the resistor strip is etched in the Al layer only. B<SP>11</SP> ions are then implanted through the oxide layer to form the resistor, the Al layer acting as a mask. The excess Al is then etched away leaving contact lands and the wafer is annealed.

Title: Aircraft control systems
IPC: G06G7/78
Filed: 1971-11-30
Abstract: 1374101 Aircraft indicators SPERRY RAND CORP 30 Nov 1971 [10 Dec 1970] 55442/71 Heading B7W [Also in Division G3] A system by means of which an aircraft can be controlled manually or automatically during take-off comprises means for producing a signal CL REF  corresponding to a reference coefficient of lift (which is related to flap angle, thrust to weight ratio and operating regulations), a signal CL corresponding to actual coefficient of lift, and a signal #V TC  corresponding to the acceleration of the aircraft along its flight path, and means 108 for algebraically summing the three signals. As shown, the system is used to operate an indicator 11 which the pilot centralizes by controlling pitch, angle, but the system may provide a signal for an autopilot. The signal CL REF  is computed by network 18, the inputs to which are flap position SF measured by a transducer and thrust/weight ratio T/W calculated by a further computer (Fig. 11, not shown). A further input E.O. is supplied if one engine (e.g. of three), fails, and this varies the gain of devices G to produce a different value for CL REF . The actual coefficient of lift CL is computed (Fig. 11), from measurements of acceleration along and normal to the longitudinal axis of the aircraft and of pitch angle from a vertical gyroscope; also from a deduction of air speed from a dynamic pressure measuring device and from a computation of vertical speed and Mach number which together are used to produce a flight path angle signal. From the same information the computer of Fig. 11, also produces the acceleration signal #V TC . The CL REF  signal is limited at 106 by an amount depending upon the potential flight path angle which is equal to "thrust minus drag over weight" (computed in Fig. 11). This value may be displayed at 113 as it represents the flight path angle that will be attained when the acceleration is zero. At a certain point ("push over") a constant signal appropriate to a speed of 250 KTS is substituted by switch 105 for the signal CL REF . The sum signal from 108 is limited at 109 to a maximum pitch angle and is combined at 111 with a pitch angle rate term to improve stability.  The Specification also describes a system for indicating a target air speed, or for automatically maintaining it; also for eliminating dynamic errors in a computer (for aircraft weight) and a computer for calculating the angle of attack, and these form the subjects of Divisional Specifications. Formulae for deriving the various required values are given, which the computers solve; details of the computer circuits elements are not given.

Abstract: 1318979 Semi-conductor devices SIEMENS AG 4 Dec 1970 [5 Dec 1969] 57669/70 Heading H1K In a semi-conductor device surrounded by an isolating region the distance between a region of the device of the same conductivity type as the isolating region and the underlying part of the isolating region is 5 to 10 Á. This reduces the effect of the parasitic transistor formed by the isolating region and the adjacent device regions. As shown, Fig. 1, P<SP>+</SP>-type regions 3, 4, 5 are formed by diffusing an impurity such as B into an N-type substrate 1 and are surrounded by channel stopper regions 7. An N-type epitaxial layer 6 is then deposited during which process the regions 3, 4, 5 and 7 spread upwards and a P--type layer 8 is formed at the substrate/  epitaxial layer interface due to rapid lateral diffusion and vaporization of impurities from regions 3, 4 and 5. P<SP>+</SP>-type regions 9, 10 and 11 are then diffused into the top surface of the wafer and a pair of complementary transistors are formed by diffusing a P-type base region 17 17 and an N<SP>+</SP>-type emitter region 16 into the N-type collector region 18 isolated by regions 10, 11, 4, 5 and 8, and by diffusing a P<SP>+</SP>-type emitter region 13 into the N-type base region 14 surrounded by P<SP>+</SP>-type collector region 9, 3. If the isolation regions 4, 5, 8 had been replaced by a single buried layer as indicated by dotted line 20 the base region 18 of the parasitic PNP transistor defined by regions 17, 18 and the buried isolation layer (20) would have been of the same order of thickness as the base region 14 of the PNP transistor shown on the left-hand side of the drawing and would therefore have had a high current gain. The actual construction used, however, provides a much thicker base region for the parasitic transistor and thus reduces its current gain to negligible proportions. The invention may also be applied to single diffused or double diffused (pinch) resistors. The substrate and epitaxial layer may alternatively by of P-type conductivity and phosphorus may be utilized to form N-type isolation regions.

Abstract: 577,202. Fatty oils. STEVENS, A. H. (Raybestos-Manhattan, Inc.). May 11, 1943, No. 7478. [Class 91] Blown oil which can be heat-bodied without development of red colour is obtained from a mechanically refined drying or semi-drying oil which has had little or no chemical refining and which has an ash content of less than 0.01 per cent. In the blowing treatment, which is conducted according to the method of U.S.A. Specification 2,178,604, an oxygen-containing gas is passed through the oil at a temperature of 25- 70‹C. until the oil, while remaining fluid, becomes soluble in a cresylic acid-formaldehyde resin at room temperature. Oils which may be used are linseed, hempseed, perilla, pilchard, menhaden and soya bean and the permissible chemical refining is the addition of a small amount of sulphuric acid to flocculate mucilaginous impurities. In an example, linseed oil is mechanically refined by filtering it through fuller's earth till it has an ash content of less than 0.01 per cent. and then blown with humid air. The blown linseed oil may be heatbodied to produce a varnish oil.
