Title: Improved spindle for x-ray goniometers
IPC: G01N23/20
Filed: 1965-05-21
Abstract: 1,078,967. X-ray goniometers. CHIRANA PRAHA NARODNI PODNIK. May 21, 1965 [May 23, 1964], No. 21585/65. Heading H5R. In an X-ray goniometer, the spindle comprises two shafts, an inner one 3 carrying a specimen or crystal mount and an outer one 1, moving around the inner one, carrying a goniometer arm 2 on which is fixed a detector, a gearing link being provided between the shafts. The outer shaft 2 has rigidily attached to it a dish-shaped helical gear wheel 4 which can if required be driven through a worm 6. The inner shaft 3 has mounted on it a fitting 10 provided with a rotatable crank shaft 8 with a bevel gear 7. A gear-wheel 12 similar to that 4 is mounted displaceably around the fitting 10. A clamp 16 is provided to fix either gear-wheel 12 or the fitting 10 (and bevel gear 7) in position by compression of platens 11, 15 respectively, or the clamp may be released to free both these units. When the platen 15 is clamped, fixing the wheel 12, rotation of the wheel 4 by worm 6 causes rotation of the bevel gear around the axis of the spindle and between the wheels 4 and 12, causing rotation of the inner shaft 3 about its own axis, at half the speed of rotation of the outer shaft, rotated by virtue of its connection to the wheel 4. By clamping the other platen 11, the inner shaft can be fixed in position and the outer shaft driven to rotate around it. Other clamping and driving arrangements are possible so that the spindle can be used for goniometers in transmission diffractions, operation on the tangential focusing principle and in crystal analysis.

Filed: 1976-05-25
Abstract: 1487547 Dielectric isolation in integrated circuits INTERNATIONAL BUSINESS MACHINES CORP 25 May 1976 [30 June 1975] 21633/76 Heading H1K In a method of forming a dielectric isolation region in a silicon integrated circuit, after providing an opening (17), Fig. 2 (not shown), in a silicon dioxide masking layer 13, Fig. 4, larger than an opening (15) in a silicon nitride masking layer 14 by etching, a recess (18), Fig. 3 (not shown), is etched in the silicon body through the openings, blocking material, typically in the form of a layer 20 of silicon oxynitride and a layer 22 of silicon dioxide, to protect the silicon in the recess against oxidation and covering the undercut portion of the silicon nitride layer 14 is then deposited in the recess, at least a portion of the blocking material in the recess and not under the silicon nitride layer is etched to expose the silicon body, the lateral etching of the blocking material being controlled so as not to expose the silicon dioxide layer, and lastly the exposed silicon in the recess is thermally oxidized to provide the dielectric isolation region 25. A P+ guard ring 19 may be provided in the recess prior to the deposition of the layer 20, and a P+ isolation region 24, Fig. 8, may be introduced prior to the thermal oxidation of the silicon. In a modified method, only a thick layer (26), Fig. 5<SP>1</SP> (not shown), of silicon oxynitride, instead of a thin layer 20 and a thick layer 22 of silicon dioxide, is provided. The silicon dioxide layer 22 is selectively removed either by sputter etching or using a buffered HF solution, and the underlying silicon oxynitride layer 20 having a comparatively slow rate of etching, is not affected by either of the two etching methods. As shown in Fig. 8, lateral etching of the layer 22 is controlled to leave a portion 22a intact. Using buffered HF solution which etches the silicon oxynitride layer 20 at a faster rate than silicon nitride layer 14, the layer 20 is removed. The layer 20 is formed by the reaction of silane, ammonia, and CO 2  and the refractive index of the layer is controlled so as not to exceed 1À74 beyond which etch rates of silicon oxynitride and silicon nitride are almost the same.

Abstract: 922,226. Annealing steel wires. LE FOUR INDUSTRIEL BELGE. June 26, 1959 [June 27, 1958], No. 22091/59. Classes 72 and 82. A process for the heat treatment of steel wires in which the wires are continuously passed into a furnace where the wire is heated by hot gases, first in an oxidizing atmosphere and then in a non-oxidizing atmosphere to a temperature of at least 700‹ C. comprises entraining the furnace gases transversely across the furnace at a minimum speed of three metres per second by means of gas burners, maintaining the zone in which the temperature is above 500‹ C. free from oxygen, and subjecting the hot wire to rapid cooling out of contact with oxygen. As shown, wires 5 enter the furnace through an inlet 2 and are heated by gases from burners 8. In the first part of the furnace, i.e. that shown in Fig. 1, the gases are oxidizing to burn off any soap or other lubricant on the wire, and in the second part, i.e. that shown in Fig. 2, the gases are non-oxidizing and the temperature of the wire may be raised to above 700‹ C. The burners adjacent the outlet 7 may be adjusted to give a carburizing atmosphere to give some case-hardening to the wire which is then passed out of contact with the air into a cooling bath 15 which may be of molten lead maintained at 500‹ C. by cooling air from a fan 25. The wire may be cooled by a transverse flow of furnace gases cooled to the desired temperature, Fig. 8 (not shown).
