Title: Improvements in the production of aluminium fluoride
IPC: C01F7/50
Filed: 1949-01-10
Abstract: Aluminium fluoride is prepared by reacting alumina, aluminium hydroxide or a mixture thereof with hydrogen fluoride gas at 350-650 DEG  C., using a fluidized solids technique.  The hydrogen fluoride may be diluted with inert gases such as air or recirculated spent gas.  The operation may be effected in two or more stages, batchwise or continuously.  The aluminium hydroxide may be partially dehydrated in a first stage at 200-500 DEG  C. by the rising hot gases, aided by the heat from a pulverized coal, oil or gas burner.  Heat may alternatively be supplied through tubes carrying hot gases, or by removing and returning the bed continuously, and heating it externally.  In the second stage, dehydration is completed and the reaction partially so; the temperature is suitably controlled by regulation of the moisture content of the incoming material, this regulation being effected by adjustment of the fuel burnt in the previous zone.  Reaction is completed and cooling effected in the lower zones.  Temperature may also be controlled by recycling aluminium fluoride fines, collected in the usual cyclone and filter or precipitator, equivalent, say, to 10 per cent of the product, or by the use of cooling water tubes in the bed.  Two forms of apparatus are shown, one consisting of a single reactor having three superposed beds with a fuel burner under the top and bottom beds, and the other of three separate reactors.  In each case, the cross-sectional area of the top or first reaction zone increases upwardly so as to reduce the gas velocity.

Title: Semiconductor laser element
Inventor: YOSHIDA ICHIRO
IPC: H01S5/00
Filed: 1990-01-05
Abstract: PURPOSE:To prevent an active layer from rising in temperature by a method wherein either of two clad layers is formed thick protruding in the direction opposed to the active layer, and a light dispersion layer formed of material whose refractive index is larger than that of the clad layer and band gap energy is larger than energy correspondent to laser oscillation wavelength is provided on the part where the clad layer is formed thin. CONSTITUTION:A current injected through a plating layer 9 and a P-type electrode 8 is injected into the stripe-like protrusion of a protrudent clad layer 5 through the intermediary of a P-type contact layer 7. A light dispersion layer 6 is formed opposite to the protrudent clad layer 5 in conductivity type, whereby a drive current can be efficiently injected into a stripe region. The injected current flows through an active layer 4 enabling it to emit light and then is discharge outside through an N-type electrode 1 passing through an N-type substrate 2 via a substrate side N-type clad layer 3. As the photo-luminescence of the light dispersion layer 6 is shorter than that of the active layer in wavelength, the layer 6 hardly absorbs laser oscillation light rays. Therefore, the light dispersion layer 6 scarcely releases heat.
