Filed: 1970-04-20
Abstract: 1287353 Data storage SIEMENS AG 20 April 1970 [21 April 1969] 18706/70 Heading G4C [Also in Division H1] A storage IGFET has multilayer gate insulation at least one of the layers being photoconductive and another of the layers being non-photoconductive and of higher breakdown voltage than the remaining layer(s). The transistor shown has a silicon body 21 bearing a thermally grown oxide coating 24. A photoconductive second layer of insulation 27 may consist of cadmium sulphide, selenium, polycrystalline intrinsic silicon or germanium, photoconductive glass, or of doped silicon nitride. The opaque gate electrodes 28 may be replaced by a single transparent electrode. When suitable pulses are applied to the gate from source 22 (used in conjunction with "speed-up" radiation from source 29) avalanche breakdown occurs in the photo-conductive layer (only) and charges are depicted at the interface between the two insulating layers. A floating electrode may optionally be placed at this interface to prevent radiation from reaching the lower insulation layer 24 of high breakdown voltage. In a variant the order of the insulating layers may be reversed. An electronic fixed-value store may be based on a two dimensional co-ordinate matrix system built up from many transistors in a common body. Stored charge may be removed from the IGFET by the application of a corresponding pulse of reverse polarity under conditions of illumination, or by intense illumination alone.

Title: Improvements in electric incandescent lamps
IPC: H01K1/32
Filed: 1935-07-01
Abstract: 459,362. Electric incandescent lamps. NAAMLOOZE VENNOOTSCHAP PHILIPS GLOEILAMPENFABRIEKEN, Emmasingel, Eindhoven, Holland. July 1, 1935, No. 18783. Convention date, July 26, 1934. [Class 39 (ii)] An electric incandescent lamp of the kind wherein a portion of the internal or external surface of the bulb acts as, or is provided with, a mirror, is so shaped that it emits a beam of elongated shape and of such proportion that the apica angle of the sectior measured in the principal plane has a value of 160 at the most, whereas the apical angle of the section in the by-plane, that is, the plane normal to the principal plane and extending through the centre of the bulb, has a value of 75 at the most. The shape of the basic curve K of the beam upon the plane V is elongated, and the intensity of the radiation in the principal plane increases towards the extreme parts of the beam, the intensity of the rays in the by-plane being substantially constant. In one form of construction the bulb 1, Figs. 4 and 5, is provided with a reflecting portion 3 extending over the arc B E D. The cross-section is such that the parts AB, CD consist of parts of parabolas extending over a sector angle of 20-40 and having the lines AD, CB as axes. The portion AC between these parabolic parts deviates from a circle having a centre M and radius MB, in that the distance from the centre to the bulb increases as the by-plane is approached more closely, so that ME is greater than MB. Preferably the incandescent body is located at the centre of the bulb, and may be rectilinear or V-shaped. In the example the filament is V-shaped, with the limbs coinciding with the axes of the parabolic portions of the bulb. The filament is supported by leading-in wires 4, 5, and a wire 8 connected to its apex is secured to a supporting-wire 6. The position of the neck and cap of the bulb is immaterial, for example, the neck could be provided in the centre of the reflecting portion.

Abstract: 1,186,169. Fingerprint recognition. C.I.T.- COMPAGNIE INDUSTRIELLE DES TELECOMMUNICATIONS. 26 April, 1967 [18 May, 1966], No. 19240/67. Heading G4R. A fingerprint-identification device compares data relating to characteristic points (intermp. tions and branches) of the unknown fingerprint with stored data of reference fingerprints. Digitized video signals from a horizontal raster scan of the fingerprint are entered into a 3-bit shift register, the majority value of the contents of which, every 2 bit times, is entered into the first column of a 3-column shift register arranged serially and having 15 bit positions per column. Every 30 bit times the majority value of each of the 15 triples of bit positions in this register (each triple consisting of a correspondinglypositioned bit from each column) is entered into the corresponding position in the first column of an 8-column shift register arranged serially except that there is provision for cyclic shift (returning to the starting position) of the 8 bit positions surrounding a particular position in the second column. Logic circuitry detects characteristic points from the 8-column shift register, their positions being stored, and determines the slopes of the tangents to the print lines at these points. Groups of characteristic points are selected, each group having a predetermined number of points all within a predetermined distance of one of them which are = then arranged in the order of increasing angle between their tangents and the tangent associated with a certain one of them. The groups have as few points as possible in common. In each group, the points are joined by straight lines (notional) in the arranged order and for each such line, its length and the angle it makes with the tangent (to the print line) at each end, are determined and stored for comparison with similar data for reference prints to identify the print.
