Abstract: 1529562 Integrated injection logic device TOKYO SHIBAURA ELECTRIC CO Ltd 29 Dec 1975 53009/75 Heading H1K An integrated injection logic device, as shown in Fig. 1A for example, comprises a substrate 11 of one conductivity type carrying a layer 12 of the opposite type through which extends an isolating ring 14 of the one type in which is formed an opposite type zone 15 which with the ring and the isolated region 12A defines a lateral injection transistor. The substrate and layer define with further zone 17 of the one conductivity type a complementary inverted vertical transistor the collector zone 17 of which is contacted by a Schottky-diode forming electrode while its base is contacted by an ohmic or, as shown, a Schottky-diode forming electrode 19E. In the Fig. 1A embodiment the vertical transistor has two identical collector zones and its base is contacted by three Schottky-diode forming input electrodes to provide with the connections shown, a multi-input and output NAND circuit. One variant of this has only a single collector zone provided with a pair of Schottky-diode forming output electrodes. In a modification of either for use as a multioutput inverter the input diodes on the base zone are replaced by a single input electrode making ohmic contact with the base via a P + diffusion and additional collectors and/or output diodes provided. To reduce minority carrier accumulation in the base an additional N+ collector zone may be provided overlapping the P+ diffusion and connected to the input electrode.

Patent GB-1326829-A (GB)
Title: Manufacture of luminescent screens
IPC: H01J9/22
Filed: 1971-12-02
Abstract: 1326829 Luminescent screens FERNSEH GmbH 2 Dec 1971 [2 Dec 1970] 55995/71 Heading C4S A method of manufacturing luminescent screens comprises coating luminescent particles 2 individually with an organic binding agent which can be removed by heating, then forming a suspension of the coated particles in a liquid, allowing the particles to settle as a cohesive layer on a carrier (e.g. glass) by sedimentation from the liquid and subsequently heating the layer to remove the binding agent. The liquid in which the coated particles are suspended is one which acts as swelling agent for the binding agent without readily dissolving the binding agent. The particles are formed tightly packed and may be scanned by a cathode-ray. Particles 2a may be coated with a colloidal organic binding agent 3 by stirring in a binding agent solution, decanting, evaporating or filtering off the excess solution and drying, the coating being a colloidal skin a few molecules thick. Whatever the particle crystal form, the coating should preferably be uniform. The coating may be p.v.a., nitro-cellulose, methyl cellulose or another organic substance or mixture capable of swelling. Screens caked together during storage may be ground. The sedimentation liquid should not readily dissolve the binding agent but should activate the adhesive properties by swelling. The suspending and sedimentation liquids are preferably the same (e.g. water or alcohol). Swelling of the coating, and so bonding, may occur over hours after precipitation. A conventional lacquer coating is not required prior to Al evaporation, the luminescent layer allowing no metal seepage. After baking, adhesion is by molecular forces. In examples, dilute binder solutions are used, e.g. 1 to 0.05% nitro cellulose in butyl acetate or acetone, a solution with specified luminescent particle concentration being ultrasonically mixed; a 2% solution of cellulose methyl ether in water with specified ZnS cone.; 0.8 to 3% PVA in water with CaMgSiO 4 . After a short precipitation, the initial sediment is discarded. In further examples, zinc silicate is coated with nitro-cellulose, ethyl alcohol, methyl alcohol, water, a mixture of water and alcohols or another which will not dissolve nitro-cellulose is poured over the luminescent substance, the solution ultrasonically agitated, the initial sediment discarded, and final sedimentation being 7 to 24 hours or more for instance. Water purified by permutite as sedimentation liquid requires 5% alcohol for example to effect nitrocellulose hardening. Alternatively yttrium silicate coated with PVA may be suspended in butyl acetate with alcohol, or a hydrocarbon. After drying at 80‹ to 150‹ C. for example, tempering to remove the binder is at >300‹ C., e.g. > 350‹ C. or preferably 400‹ C. or higher.

The compound B may comprise a group which alkylates or acylates the macromolecular compound and as the polymerizable group a carbon-carbon or carbon-oxygen double bond. The coupling function may be an oxirane, ethyleneimine, halide, acid halide, azide or anhydride group and may, for example have the formula in which R 1  is a mono- or polyunsaturated aliphatic hydrocarbon radical optionally containing one oxo group adjacent to a double bond and R 2  is a hydrogen atom or a lower alkyl radical. Compound B is preferably acryloyl chloride, allyl bromide, maleic anhydride, maleic acid azide, 1-allyloxy-3-(N-ethyleneimine) - propan - 2 - ol, acrylic acid 2,3 - epoxypropyl ester, but-2,3-ene oxide, methacrylic acid-2,3-epoxypropyl ester, maleic acid 2,3- epoxypropyl monoester, fumaric acid epoxy-(2, 3-epoxypropyl ester), fumaric acid epoxy-(2,3- epoxypropyl diester), fumaric acid epoxy-(2,3- epoxypropyl diester) or 1-allyloxy-2,3-epoxybutane. The molecular sieve material is advantageously cross-linked dextran, cross-linked polyacrylamide or cross-linked agar. In the examples glucose oxidase is coupled to an acrylamide/N,N<SP>1</SP>-methylene bis-acrylamide copolymer obtained by polymerization thereof using ammonium peroxydisulphate or to a cyanogen bromide activated cross-linked dextran gel. Poly A is attached to a polyacrylamide/N,N<SP>1</SP>- methylene bis-acrylamide copolymer.

Abstract: 1,191,310. Methanol, purification by distillation. CHEMICAL CONSTRUCTION CORP. 12 Dec., 1967 [16 Dec., 1966], No. 56488/67. Heading B1B. [Also in Division C2] Crude methanol, such as that produced by catalytic synthesis from carbon monoxide and hydrogen, or by partial oxidation of hydrocarbons, is purified by introducing the crude methanol through line 3 and heater 4 into zone 6 where the crude is subjected to water extractive distillation so that low boiling ethers, ketones and aldehydes, are removed in overhead vapour stream 9, and submitting the partially purified aqueous methanol, withdrawn from the bottom of zone 6 through line 17, to rectification in column 18 from the side of which two purge streams are withdrawn. One purge stream 28, which contains ethanol, is withdrawn above the point of introduction of the aqueous methanol; and the second purge stream 29, which contains higher alcohols, is withdrawn from a vapour phase in the lower section of column 18. The required purified methanol is withdrawn in the liquid state from the upper section of column 18 through line 23. Water, discharged from the base of column 18, may be in part recycled through line 21 to zone 6. The water used in zone 6 is preferably made slightly alkaline, e.g. with NaOH introduced through line 8. Vapour stream 9 is passed to cooler 10, from which part of the condensate is refluxed to zone 6, while the remainder is discarded through line 15. The vapour leaving the top of column 18 is passed to cooler 25, part of the condensate is refluxed to column 18, and the remainder is recycled through line 2 to zone 6. Methanol may be recovered from purge stream 28, via an auxiliary distillation, and recycled to the middle or upper section of column 18. Vapour purge stream 29 flows to cooler 30, and the condensate passes to vessel 32 where it separates into a heavy alcohols-rich phase and a water-rich phase. The feed stream to zone 6 may be split and introduced at two or more points, and the same applies to the stream 17 fed to column 18.
