Title: Improvements in or relating to erasing stored information
IPC: G03G16/00
Filed: 1963-12-02
Abstract: 998,449. Electrophotographic processes. INTERNATIONAL BUSINESS MACHINES CORPORATION. Dec. 2, 1963 [Dec. 31, 1962], No. 47383/63. Heading G2H. [Also in Division G5] A method of erasing all or part of information stored as deformation of one surface of a thermoplastic material, comprises applying a uniform charge to at least a portion of the deformed surface and heating the surface to render it plastic. In Fig. 2 information is stored as. deformations 34, 36 in a thermoplastic layer 18 on a dielectric base 14. The area 42 is charged uniformly by a corona discharge device 50 comprising a high voltage electrode 56 and a control grid 62 within an insulator housing 58, electrodes 56 and 62 being maintained, for example, at 6000 volts and 1200 volts respectively. The base 14 is earthed at 64 and the area 36 which is not to be erased is shielded by a foil 66 which is earthed via switch 68 after the charging process is completed. In a modification the record is inverted, as shown in Fig. 3, and arranged between earth 64 and corona discharge device 50 which has its polarities charged to produce a charge of opposite sign on the base 14. During this process the part of the base opposite area 36 may but need not be shielded by the foil 66. The surface 18 is then heated e.g. by hot air, to render it plastic, and the deformation 34 disappears. Erasure requires the combination of charging and heating, and one but not both of these processes may be applied to other areas from which deformations are not to be erased. The charge applied is preferably of opposite sign to that used when recording, since in this case a lower temperature suffices for erasure.

Title: An optical scanner
IPC: H01S3/101
Filed: 1966-11-02
Abstract: 1,111,058. Lasers. INTERNATIONAL BUSINESS MACHINES CORPORATION. 2 Nov., 1966 [29 Dec., 1965], No. 49049/66. Heading H1C. [Also in Division G2] An optical scanner providing a circular scan comprises a source 10 of linearly polarized light, Fig. 1, a polarization rotator 26, and an analyser 50 receiving the rotator output and passing only that filament 58 of the polarized light beam which is polarized in a given direction, the rotator being electrically controlled so as to produce a variable polarization rotation and thus enable different light filaments to become effective in turn along the scanning path. In the arrangement shown the linear polarization 62 of each light filament emitted by a laser light source is tangential to a circumference about the geometric axis, and the rotator comprises a quarter wave plate 28 and two vertically-spaced and independently energized electro-optic crystals 30, 32 with transparent electrodes 34, 36, 42, 44. The use of two electro-optic crystals is necessary to enable the analyser 50 to differentiate between diametrically-opposed light filaments which have parallel linear polarizations. The light source, Fig. 2, comprises a frusto-conical bi-refringent crystal having its optic axis 16 parallel to the geometric axis 18, the centre of the crystal being formed with two conical cavities 20, 24. This crystal totally reflects linearly polarized ordinary rays 58 of incident light 54 and disperses the extraordinary rays 56. The reflecting laser crystal and a partially transmitting mirror 52 together form the laser resonator. In an alternative arrangement, Fig. 4, a laser comprises a right circular cylindrical crystal rod 80 having its optic axis 84 inclined at 60 degrees to the geometric axis 82, the resonator being formed by separate mirrors 86, 88. As all the light emitted by the crystal is linearly polarized in the same direction, selection of a required light filament after rotation by a rotator 90 comprising an electro-optic crystal 92 and a quarter wave plate 102 is effected by an analyser formed of several analyser segments 106-118 radially oriented with respect to the geometric axis. The crystal 92 may be divided. In a modification laser action is not used, the crystal of Fig. 1, being illuminated from a narrow-band light source 72, Fig. 3, through a collimating lens 74 and a beam splitter 76. End illumination of the crystal 80 is used in the modified Fig. 4 arrangement, Fig. 5 (not shown). In both cases the resonator components are omitted.

Abstract: 1421069 Making porous metal tubes EUROPEAN ATOMIC ENERGY COMMUNITY 23 Oct 1973 [26 Oct 1972] 49294/73 Heading B3A [Also in Division F2] A method of making porous tubes comprises helically winding one or more strips of metal cloth with its or their edges overlapping to form a tube, bringing either the inner or outer surface of the tube into contact with a support member and sintering the cloth. The support member may be a mandrel, preferably of ceramic, or the wound tube may be located in a member formed of half-shells, in which case ceramic beads are placed inside the tube to ensure that it bears uniformly against the halfshells and the beads may be compressed. To ensure further uniformity of pressure against the half-shells, the tube may be vibrated during sintering. The cloth may be wetted, e.g. with acetone, alcohol or water, and rolled prior to being wound to produce pores of required size. The wound tubes are cleaned by annealing in high vacuum and sintering is performed in a shielding atmosphere, e.g. in high purity hydrogen or in rare gases.

Abstract: 1,126,587. Transistors. SIEMENS AG. 30 Nov., 1965 [1 Dec., 1964], No. 50688/65. Heading H1K. In a transistor for use in high-frequency amplifiers where reduction of cross-modulation is important at least the uniformly doped part of the collector zone adjacent the collector junction is of high resistivity and has a doping concentration No such that at a collector current less than 10 mA the collector current density is >VgrNcq, where Vgr is the limiting velocity in the base zone of minority carriers injected by the emitter and q the elementary charge, and the ratio of doping density on opposite sides of the emitter junction is non- uniform over the emitter area. In such a device the effective base width varies markedly in accordance with collector current. A typical device of mesa type, which can be made in multiple, comprises a low resistivity P-type germanium collector wafer carrying a high resistivity P layer formed by epitaxial deposition. The base region is formed by diffusion and the emitter by vapour depositing aluminium-gold through a mask and alloying. Non-uniformity of the emitter junction is achieved by varying the base doping adjacent the emitter junction along a line parallel to the junction with or without a corresponding variation in base zone thickness. A periodic variation of base doping can be produced by forming the base zone in two diffusion steps in one of which spaced areas are oxide masked. An effective lateral variation of base doping can alternatively or additionally be produced by alloying the emitter to a non-uniform depth in the graded base zone formed by diffusion. This may be done by cutting the surface on which the emitter is to be formed at an angle to a 111 crystallographic plane. The resulting emitter is wedge-shaped (Fig. 4, not shown) for an angle of 1À5 to 2 degrees, of sawtooth form for an angle of just over 4 degrees and convex (Fig. 6, not shown) if the surface lies in a 110 or 100 plane.
