A continuous casting mould 10 comprises a liner 11 supported by a bolted on back-up structure 13 having water inlet and outlet pipes 31, (32), (Fig. 2, not shown), the liner being formed of high heat conducting, e.g. copper, members 16, 17 welded together along adjacent edges 18 to form a polygonal mould cavity 12 having no welds at corners. The rectangular mould cavity 12 described is formed by channel section members 16, 17 made from rolled copper sheets to form side walls 14 and end walls 15, which may be closer together at the bottom than at the top to produce a longitudinally tapering mould. The mould surfaces are machine finished and water cooling grooves 20 are machined on their outer faces, the thickness of copper between the mould surface and the ends of the grooves being sufficient to allow re-machining of the mould surface after scratching and erosion in use. Grooves 29 are provided at the top and bottom of plates 21, 22 forming the back-up structure 13 to allow passage of cooling water, seals 33, 35 also being provided. A vertical line of thermocouples (45) may be provided to monitor the temperature along the mould and ascertain the level of molten metal therein. The copper members 16, 17 may be welded together using a copper wire electrode with a mixture of helium and argon to form an inert gas shield. A continuous weld is formed by a succession of weld beads.

Abstract: 990,119. Semi-conductors. MERCK & CO. Inc. Nov. 23, 1961 [Nov. 29, 1960], No. 41983/61. Heading H1K. A semi-conductor body comprising a single mono-crystalline structure is made by the epitaxial deposition of semi-conductor material containing active impurities on to asubstrate of the material having a surface which conforms to within half a degree to a crystal growth plane. The substrate is cut from a zone refined single crystal to expose a large area growth plane. With silicon the (211) growth plane may be located in a (111) oriented zone refined rod by etching a characteristic vibration line on the rod with KOH and using the etched line to reflect a light beam back along its path. The rod may then be cut perpendicularly to the light beam and along the length of the rod to expose the (211) growth plane. A (111) growth plane may be similarly exposed in a (211) oriented rod. The exposed surface of the rod is lapped with 600 mesh alundum powder, is etched in a solution of nitric and hydrofluoric acids and is washed and dried. A single crystal 0À006 inch thick silicon layer forming an extension of the single crystal substrate lattice may be deposited on the (211) growth plane of an N- type silicon substrate by heating the substrate to between 1150‹ C. and 1250‹ C. and exposing the growth plane to a gas flow of 240 gms./hour silico-chloroform entrained in 330 litres/hour of hydrogen containing sufficient boron trichloride to provide 10<SP>18</SP> carriers/c.c. of silicon. Deposition is allowed to take place for 30 minutes.

Title: Semiconductor arrangements for generating electromagnetic radiation in the range consisting of the infra-red and visible spectral ranges
IPC: H01L33/00
Filed: 1965-10-04
Abstract: Infra-red or visible light is generated by a device comprising a body of semi-conductor material having within it elongated pointed parallel aligned inclusions of a second phase of comparatively good electrical conductivity there being a rectifying action between the inclusions and the body, and said light being generated when the device is disposed in an electric field parallel to said inclusions. The inclusions are not more than 20 degrees out of parallel and preferably not more than 10 degrees.  The inclusions are preferably accicular and may be made from quasi-binary systems wherein an element or a compound in accicular form is precipitated out of melt on solidification of the melt.  The preferred semi-conductor materials are AIIIBV or AIIBVI compounds o In, Ga, P, Sb, As, Zn, Cd and S, with inclusions of Ni, Cr, Mo, Fe, Mn, Co, As and Sb compounds. It may be necessary to cool the solidified bodies to liquid air temperature to produce the inclusions. The inclusions may not be distributed evenly throughout the body, they may be situated towards one end or form two sets one at either end of the body. Contact may be made between the electrodes and the inclusions by cutting the body perpendicularly to the inclusions, etching to expose the inclusions and applying the electrode to the body.  The electrodes are capacitative and when a field is applied across them, charge carriers are injected into the body from the inclusions.  On reversal of the field, charge carriers of opposite sign are injected and combine with the first carriers to give electroluminescence. Even without field reversal, recombination takes place.  The body may be thin (e.g. 100 to 300 m ) to prevent absorption of emitted light and may have portions of different dopant level.  The inclusions may be aligned in parallel by unidirectional freezing or zone-melting. There may be a potential barrier between the body and one or both of the contacts, but where the contacts touch the inclusions then an ohmic connection is made to the inclusions.  Specification 1,045,978 is referred to.
