Title: Process for Batchwise Enzymatic Degradation of Highly Concentrated Starch Suspensions
IPC: C08B30/18
Filed: 1966-12-23
Abstract: 1,160,917. Enzymatic starch degradation. SCHWEIZERISCHE FERMENT A.G. 23 Dec., 1966 [28 Dec., 1965], No. 57632/66. Heading C3U. Dextrin solutions are made by enzymatic degradation of a starch suspension, e.g. using alpha-amylase, below the glutinization temperature, to such an extent that upon subsequently heating to above the glutinization point the increase in viscosity is low enough to permit stirring of the suspension at all times, degradation being continued at this second temperature to the desired end viscosity. Starch suspensions of up to 40% concentration may be hydrolysed in this way. Maize or potato starch may be used, and the viscosity and temperature monitored by programme.

Filed: 1969-12-16
Abstract: 1299890 Programmed control of machine tools SAAB-SCANIA AB 16 Dec 1969 [16 Dec 1968] 61292/69 Heading G3N A workpiece is machined, in response to numerical information, by an automatically controlled machine tool; the information being derived from control paths defined by the intersection of an arcuate generatrix part of a rotary tool with parallel spaced planes extending through the workpiece in the feed direction. As shown, Fig.2, a workpiece 3 from which an object 2 is to be machined by co-ordinate movement in the Z, Y plane and incremental movement along the X axis by an arcuate-edged cutter, not shown, rotating about an axis maintained parallel with the Z axis. The workpiece is positioned on a machine table by dowels 6 and the cutter is mounted on a numerically controlled machine, responsive to a prepared programme representative of the desired movement of the centre of the arc generating the cutting surface. The programme is prepared by considering the locus of the cutter centre when moving around the surface in an inter-secting plane 4', 4". The position of the cutter centre is adjusted for the curvature of the body in the Z, X plane, Fig. 3 by calculating the normal 12 to the surface, erecting a perpendicular at a distance equal to the cutter radius r, the intercept with the plane 4 being the programmed position 13 of the cutter centre. Alternatively, a circle is calculated concentric with the surface at inter-section 5 having a difference in radius of r, or, a surface calculated parallel to Z and displaced by a distance r. The specification also discusses the derivation of a programme for a cutter having a centre for the generatrix of the cutting edge which does not lie on the axis of rotation of the tool.

Title: Method for producing semiconductor device utilizing ion implantation
IPC: H01L29/00
Filed: 1969-12-24
Abstract: 1280199 Ion implantation in semi-conductors HITACHI Ltd 24 Dec 1969 [27 Dec 1968] 62898/69 Heading H1K The double ion-implantation process of the invention may be applied to the manufacture of the planar transistor shown. A silicon body consists of a 0À01 ohm. cm. substrate 1 bearing an epitaxial layer of 10 ohm. cm. resistivity and 1-3 Á thickness. The N-type base region is formed by ion-implantation of phosphorus through an apertured silicon oxide mask formed by oxidative decomposition of silane or by thermal oxidation of the semi-conductor surface and shaped by etching or by ion-beam or electron-beam machining. Implantation is carried out at a temperature in the range 600- 700‹ C. so that the impurity diffuses rapidly via the lattice defects caused by the process (though these defects are annealed out during the process because of the high temperature used). The diffusion ensures a relatively uniform impurity distribution in the base region. A further silicon oxide layer is formed by oxidative decomposition of silane at 700-800‹ C. and an emitter aperture is formed therein. Ion implantation of boron is then carried out at a temperature in the range 400-600‹ C. Temperatures in this range are sufficiently low to prevent diffusion of impurity via the lattice defects formed but are sufficiently high to anneal out the defects during implantation. The oxide layers are etched off with hydrofluoric acid and replaced by a passivating layer of silicon oxide, silicon nitride or alumina and emitter and base electrodes provided. The collector electrode 16 is formed by nickel plating. The temperature ranges (T 1 >600‹C., 400‹ C.#T 2 #600‹ C.) are applicable to other impurities and semi-conductors. Temperatures of all processing stages (including coating) may be kept below 800‹ C. to avoid displacement of impurities by normal thermal diffusion. In general the area of impingement of the ion beam may be restricted by a metal mask in the beam or by a coating, on the semi-conductor body, of silicon oxide, silicon nitride, alumina, combinations of these, or of such a coating overcoated with chromium, tantalum or nickel.

Abstract: 758,710. Electric measuring apparatus. PHILIPS ELECTRICAL INDUSTRIES, Ltd. Dec. 31, 1954 [Jan. 4, 1954], No. 37826/54. Class 40(1) The unbalance voltage of a bridge circuit is automatically balanced by a voltage from two potentiometers in cascade adjusted simultaneously so that in the balance condition the position of the sliders is proportional to the square of the unbalance sector of the bridge. As shown (Fig. 4), a measuring bridge R<SP>1</SP>-R<SP>4</SP> compris ing one or more strain gauges, has its unbalance voltage opposed by a voltage from a potentiometer 10 forming two arms of a further bridge fed from a second potentiometer 4. The difference voltage is amplified at V to feed a reversible motor M which drives the mechanically coupled sliders 9, 5 of potentiometers 10, 4 to balance position so that a square law relationship exists between the unbalance voltage of the first bridge and the balance position of the potentiometer sliders. The amplifier V may also be fed with a first derivative component from a tacho-generator G (Fig. 5), to effect damping. The first bridge may be one for measuring temperature mechanical pressure or fluid flow.

Title: A process for the production of a semiconductor storage cell
IPC: H01L27/10
Filed: 1978-08-02
Abstract: A storage cell comprising an MOS field-effect transistor having a high storage capacitance provided by one of its two p-n junctions, is produced in the surface of a semiconductor crystal by at least three diffusion or implantation steps. In a preliminary masked doping step at a surface area E of crystal (1), a region (7) is produced of the same conductivity type as the crystal (1) but more strongly doped. Within region (7), the one zone (2) of the field-effect transistor forming the storage capacitance is produced in two redoping steps. In the first step, employing a mask exposing an area A of the semiconductor surface there is produced a region (2) of the opposite conductivity type to that of crystal (1) defining a p-n junction lying within region (7). In the second step, employing a mask exposing only a sub-area B of area A, a dopant producing the same conductivity type as that of region (7) is introduced until the remaining part of redoped region (2) acquires the L-shaped profile shown. <IMAGE>
