IPC: H01L27/00
Filed: 1967-07-20
Abstract: 1,153,949. Semi-conductor devices; image pick-up tubes. HUGHES AIRCRAFT CO. 20 July, 1967 [21 Sept., 1966], No. 33321/67. Headings H1D and H1K. A vidicon camera tube 10 has a target 12 made up of a mosaic array of silicon semiconductor diodes which in use is scanned by an electron beam. The diodes comprise a series of PN junctions formed between a layer 28 of N- type material and an array of mutually insulated and spaced apart areas 30 of P-type material. A transparent film 22 of conductive material forming an electrode is coated on the surface of the silicon layer and is in contact with the glass faceplate 32 of the tube. The dark charge-storing time of the PN junctions is greater than the raster scan time of the electron beam and the semi-conductor material is designed to have a resistivity to produce this effect, that is in the case of silicon between 0À01 and 0À1 ohm-cm. In order to attain a 500 lines/in. television resolution the dimensions of the individual elements are 0À0015 inch by 0À0015 inch and so that the resolution is not degraded by lateral diffusion the thickness of the semi-conductor material is less than 0À0025 inch. To eliminate an undesirable signal due to the electron beam scanning the areas between the diodes these areas are covered with an oxide layer of resistivity greater than 10<SP>12</SP> ohm-cm.

Title: Production of sugar ester-borate complexes and sugar esters
IPC: C11C3/00
Filed: 1962-08-31
Abstract: A laundry detergent composition comprises at least one sugar ester-borate complex or sugar ester in admixture with a detergent synergizing aid.  Examples of these aids are the molecularly dehydrated phosphates, the alkali metal phosphates, alkali-metal silicates, sulphates, carbonates and carboxymethylcellulose.  The complex and/or ester may be present in an amount ranging from 7.5 to 30% by weight of the composition.  Examples are given in which the sugar derivatives are glucose caprate borate complex, glucose laurate borate complex or glucose myristate borate complex and the detergent aids are sodium tripolyphosphate, sodium metasilicate, carboxymethyl cellulose, dense ash with or without sodium lauryl sulphate.ALSO:Sugar ester-borate complexes are made by reacting in the presence of glacial acetic acid as the solvent reaction medium a sugar with orthoboric or metaboric acid or boron oxide to form a reaction product soluble in glacial acetic acid, reacting a fatty acid halide with said reaction product to form a fatty acid ester of the sugar boron reaction product, and removing glacial acetic acid from said fatty acid ester of the sugar-boron reaction product.  The reaction of the sugar and boron compound is preferably effected at temperatures from 85 DEG  to 115 DEG  C. for periods ranging from 15 minutes to 60 minutes.  The sugar employed may be a mono-, di-, tri- or tetra-saccharide, preferably glucose or sucrose.  The fatty acid halide is preferably one containing 6 to 24 carbon atoms. The reaction with the sugar-boron product preferably takes place at 25 DEG -50 DEG  C. and the hydrogen halide liberated is removed by distillation. The glacial acetic acid is likewise distilled off. Fatty acid sugar esters are obtained by heating the sugar ester-boron complex with a monohydric alcohol of 1-4 carbon atoms and removing a borate ester of the alcohol from the reaction mixture by distillation. Examples describe the preparation of a glucose caprate ester and borate complex, glucose laurate borate complex, glucose laurate, glucose myristate and borate complex, sucrose myristate and borate complex.  The esters and complexes possess excellent detergent, wetting and dispersing properties.
