Abstract: Bei einem Flüssigphasenepitaxie-Verfahren wird zur Herstellung der die Halbleiterstrukturen (10, 11a, 11b) enthaltenden epitaktisch abzuscheidenden Siliziumschicht (8) als Lösungsmittel eine Schmelze aus einem Metall verwendet, welches mit Silizium gesättigte Lösungen unterhalb von 900°C bildet und in den Schichten keine Dotierung erzeugt, die einer Konzentration von größer 10¹<7> Dotieratome/cm³ entspricht. Vorzugsweise wird wegen des bei 370°C liegenden Schmelzpunktes des Eutektikums Gold/Silizium eine Goldschmelze verwendet. Durch die Erfindung ist die Möglichkeit gegeben, die Flüssigphasenepitaxie bei sehr niedrigen Temperaturen durchzuführen und auf diese Weise einkristalline Siliziumschichten (8) auf mit Isolationsschichten (5, 6) versehenen Substraten (1, 2, 3) zu erzeugen, wie sie für die dreidimensionale Integration in der Mikroelektronik erforderlich sind.

Abstract: Direct digital measurement makes it possible to determine the parameter of any object to be measured (for example a capacitor) with little expenditure and with high accuracy by deliberately using digital technology, eliminating, in particular, measurement inaccuracies such as originate from, for example, measuring circuit tolerances and unavoidable interfering variables such as offset influences, drifts and the like and making it possible directly to analyse and display the measurement result determined, in connection with which it is possible, at the same time, to miniaturise the measuring device and thus integrate it into the sensors because of the small amount of components required. …<??>In this method, an auxiliary variable with digital pseudo-random time variation, predetermined by a microprocessor, is applied to the object to be measured - this time variation being interrupted for a predeterminable period of time after each measuring interval. …<??>The analog measurement signal is supplied to the processor via an analog/digital converter. The components of the measurement signal resulting from the known auxiliary variable are filtered out and only the components resulting from the auxiliary variable are used for determining the measurement variable. For this purpose, the control signal to be output by the processor is processed with the measurement signal to form a cross-correlation-like function.

The plastic worked product has a coating of the lubricating oil on its surface which provides an excellent anticorrosive effect for steel stocks. 
     The oil may also contain at least one extreme-pressure additive selected from:
     (1) condensed phosphoric acid,   (2) phosphite and phosphate esters,   (3) organic sulfur compounds, and   (4) organic chlorine compounds.

Abstract: The transmission ratio of an automotive continuously variable transmission is controlled on the basis of the difference between a target rotational speed of the engine which is preset according to an indication of the driver's intention of acceler-a-tion or deleration and a detected rotational speed of the engine. The gain of the rate of change of the transmission ratio is reduced as the detected rotational speed of the engine becomes higher, and the gain of the rate of change of the transmission ratio is increased as the detected rotational speed of the engine becomes lower. Alternatively, the gain of the rate of change of the transmission ratio is of a relatively small value when the detected rotational speed of the engine is equal to or higher than a preset speed, and the gain of the rate of change of the transmission ratio is of a relatively large value when the detected rotational speed of the engine is lower than said preset speed.

Abstract: The invention relates to the making of a voluminous yarn and an arrangement for carrying out the process on texturing machines, making it possible to produce a wide range of diverse voluminous yarns. A synthetic filament yarn passes from the supply bobbin via a pair of feed rollers through a heater, where it is set, from there into the texturing station, where it is false twisted, and on to a second pair of feed rollers and is then, between the second and third pair of feed rollers, air-bulked and from there passes to the take-up package or first to a further heater and then to the take-up package. According to a further feature, the yarn is post-set in a further heater between the second and third pairs of feed rollers and then air-bulked between the third and a fourth pair of feed rollers before being wound up on a dyeing package. The air-bulking and winding are each performed with a defined yarn tension. <IMAGE>

Abstract: The invention provides a method of forming a dispersion of base degradable hydrophobic component for a photographic system. The invention is accomplished by mixing the component, solvent, and surfactant, at an elevated temperature if necessary, metering the mixture of solvent, surfactant, and hydrophobic component to an excess of water with agitation so as to precipitate from the water solvent solution small particles of the hydrophobic component. The small particles then form a stable dispersion, after washing by dialysis or diafiltration, that will not agglomerate during storage prior to use. The preferred photographic component for use in the system of the invention is an ester terminated photographic coupler that would decompose if subjected to the high pH treatment of prior art procedures.
