Abstract: 1,052,216. Electron beam apparatus; semiconductor devices. STANDARD TELEPHONES & CABLES Ltd. Nov. 19, 1963, No. 45599/63. Headings H1C, H1D and H1K. In a semi-conductor laser excitation is by means of an electron beam. A slice of semiconductor material 1 such as gallium arsenide has its two main faces 2, 3 made parallel and reflecting either by polishing or the deposition of multi-layer dielectric or metallic coatings so as to form a resonant cavity. The slice 1 is sealed in the end of a vacuum tube 4 containing an electron gun so that a beam 5 of high-voltage electrons is directed on to the spot 6 so as to excite the semi-conductor material and stimulate electromagnetic radiation therein. Due to the resonant cavity formed by faces 2, 3 a beam 8 of coherent and collimated light emerges from the face 2. The whole apparatus is cooled to a low temperature. The selectron beam may be scanned across the slice 1 by deflector plates or coils and the beam 5 may also be modulated in intensity so that the emergent radiation 8 is a modulated beam of light emanating from a fixed or variable position. The slice may form part of a hollow sphere.

Abstract: 1,052,943. Cathode-ray tube circuits. ELECTRIC & MUSICAL INDUSTRIES Ltd. Aug. 30, 1963 [June 2, 1962], No. 21353/62 Heading H4T. Damage to the luminescent coating carried by the anode 3 of an image intensifier tube 1 and caused by the flow of excessive electron current from the photocathode 2 when the latter is subjected to high illumination is prevented by reducing the operating potential from source 8 when the current exceeds a predetermined value. This source, in addition to supplying the multiplication and accelerating electrodes 4, 5, also supplies the focusing electrodes 9 so that, when the potential across the resistor chain R1 . . . R18 is reduced the luminous image on anode 3 remains in focus. In the arrangement shown the potential across anode resistor R19 is taken as a measure of the tube electron current and this potential is converted into a fluctuating unidirectional control signal by intermittently short-circuiting R19 by means of contacts RL1/1 operated by a 50 c.p.s. relay RL1, the D.C. component being then removed by C1 and after amplification in A1 and rectification by RV1 utilized to control the source 8. In alternative arrangements the control signal may be produced by means of a television camera, photo-cell or photomultiplier " viewing " the anode 3. Instead of electrostatic focusing the image intensifier may employ magnetic focusing in which case the current fed to the focusing coils is varied appropriately to maintain correct focus as the voltage applied to the anode and accelerator electrodes is varied. The image intensifier may be associated with the pick-up tube of a television camera to increase the sensitivity of the latter the optical coupling being provided by means of a lens or a fibre optical device.

Attachment of contacts to the base zone of a PNP (NPN) transistor sandwich is facilitated by diffusing of donor (acceptor) impurity into the entire surface of the base zone and adjacent parts of the other zones only to form an extension of the base zone. One or more contacts are then attached to the extended zone. In one embodiment the sandwich is coated with silica, by vapour deposition if the semi-conductor is germanium or by oxidation if it is silicon. After removing the silica overlying the base zone and adjacent parts of the outer zones by etching through wax masking the PNP sandwich is subjected to arsenic vapour at 800‹ C. for an hour to extend the base zone. If desired when the emitter zone is more heavily doped than the collector conversion of the exposed part of the emitter to N type can be avoided by a suitable choice of the concentration of arsenic in the vapour.

[Also in Division C3] A process for the chemical metallization, and optional electro-plating, of plastics comprises mixing the plastics material (A) with a filler (B) which contains functional groups capable of combining with metals which catalyse metallization or is able to develop such groups through suitable pre-treatment and one or more polymers (C) of softening point lower than material (A), e.g. in the range 30 to 100‹C., and which can be oxidized in conventional conditioning baths; chemically depositing metal from a solution of a salt thereof containing a reducing agent in the presence of a metal which catalyses the deposition, and optionally electro-plating the product. Examples describe the electro-plating in a copper plating bath of articles moulded from compositions comprising (1) polypropylene, ethylene/vinyl acetate copolymers and silica or calcium silicate, and (2) polyethylene, polyisobutylene and silica or sodium aluminium silicate, which have been treated with chromosulphuric acid, ammoniacal silver nitrate and a chemical plating bath comprising copper sulphate, Rochelle salt, sodium hydroxide, sodium carbonate and formaldehyde. In a further example (3) articles as in (2) are additionally treated with sodium hydroxide solution after the chromosulphuric acid treatment.
