Patent EP-0020936-A1 (EP)
Inventor: MCGOUEY RICHARD PETER
IPC: G11C11/14
Filed: 1980-04-25
Abstract: A thin magnetoresistive layer (34), such as permalloy, is blanket deposited over a substrate (10) including a bubble domain film (30), and is then selectively "poisoned» to destroy its magnetization except in those areas where thin sensors (22) are to be provided. The poisoned portions of the magnetoresistive layer serve as a plating base for conductor metallurgy which can be used as an ion implantation mask, and for carrying electrical current. This eliminates some process steps which had been required in the prior art, and does not leave magnetic permalloy in those areas of the bubble domain chip where they would adversely affect propagation of domains by ion implanted contiguous propagation elements. This technique can also be used to make bubble domain devices having gapped propagation elements.

Abstract: A semiconductor integrated circuit using charged coupled device (CCD) technology for performing demodulation of time-varying signals which have been phase or amplitude modulated. The CCD circuit performs a sampling of the time-varying signal at a suitable sampling frequency depending upon the frequency of the phase or amplitude modulation of the carrier. The CCD device (12) converts the sample into an equivalent charge packet which is used to control the control electrode (31) of a field effect transistor (13) in an amplifier circuit. The magnitude of the sample is representative of the amplitude of the carrier so that the output of the field effect transistor (13) represents a demodulated signal. The circuit is a braod spectrum device, operable with a signal frequency from the audio into the gigaHertz (GHz) frequency range.

Abstract: Die Erfindung betrifft die Herstellung von wasserverdünnbaren Bindemitteln, die durch Umsetzung von Monoaddukten aus N-hydroxyalkyl-oxazolidinen mit aromatischen, cycloaliphatischen und aliphatischen Diisocyanaten mit den Hydroxylgruppen eines Polykonensationsharzes, Polymerisationsharzes oder Polyadditionsharzes erhalten werden. Das Endprodukt weist eine Aminzahl zwischen 30 und 100 mg KOH/g auf und wird durch vollständige oder teilweise Neutralisation der Aminogruppen mit Säuren wasserverdünnbar gemacht. Die Produkte eignen sich insbesondere als Bindemittel für Lacke, die kathodisch abgeschieden werden. Durch ihre Zusammensetzung geben sie beim Einbrennen viel weniger Spaltprodukte ab, wodurch sich die Korrosion der Anlagen wesentlich verringert.

Abstract: A process for coating flexible photographic record carriers with liquid, highly viscous photographic coating compositions. The record carrier (6) to be coated is transported between two rollers (7 and 8), one (8) of which has a flexible surface and the other (7) a highly polished surface. The two rollers are pressed together with a pressure of approximately 5 to 50 kg per cm of roller width. One of the rollers (7) can be motor-driven and effects the transport of the record carrier, the other roller (6) being free running. The photographic coating composition is applied by means of an extruder (1) in the form of a liquid film, oriented transversely to the record carrier, in the inlet section of the roller nip to the side of the record carrier situated opposite the highly polished roller surface and then immediately pressed onto the record carrier in the roller nip. The surface of the highly polished roller is cooled to at least 20 DEG C, preferably 0 to 10 DEG C, so that the coating composition does not adhere to the highly polished roller and spontaneously solidifies on the record carrier. The chosen transport speed of the record carrier (6) is 2 to 50 times higher than the speed at which the coating composition emerges from the extruder slot. The considerable stretching of the highly viscous coating composition thereby produced yields a corresponding reduction in the layer thickness, so that dry layer thicknesses of only 2  mu m can be achieved with great precision, for example, with slot widths of  200 to 300  mu m. <IMAGE>

Abstract: An annular vane (20) having a truncated hyperboloid configuration is disposed in a portion of a turbo compressor induction passage (22) having a similar curvature. The vane (20) defines inner and an outer sub-passages (28.30) the cross sectional area of the inlets (32,36) of which may be varied by moving the vane axially with respect to the compressor wheel while the outlets (34,38) of the two passages remain substantially unchanged. As the surge limit is approached the vane is moved away from the compressor wheel to increase the flow passing through the outer passage (30) while reducing that which passes through the inner one (28). The resulting increased flow velocity through the outer sub-passage (30) reduces the angle of incidence of the air impinging on the compressor wheel blades (18) suppressing the surge tendency.

Abstract: The stove for a hot air heating system has a cylindrical fire grate in metal with the lower part lined with refractory material. The base of the fire grate forms a grid and the grate has a top cover with four holes. The hot gases from combustion flow through the holes into tubes and into a metal chamber. Baffles inside this chamber deflect the hot gases to an outlet leading to a chimney. The grate is surrounded by an outer casing with air inlets in its base. Air flowing into these inlets flows upwards over the external surfaces of the grate and around the chamber with a continuously rising temperature. The heated air then flows through outlets in the top of the housing to heat the room. Fuel is supplied through a door and ash is removed by the tray.
