Abstract: A process for depositing silicon dioxide on silicon wafers at low pressure from tetraethoxysilane includes a step of introducing a constant flow of nitrogen into a vacuum pump (18) in parallel with exhaust flows from a deposition tube (16) containing the silicon wafers. Tetraethoxysilane is vapourised and flowed into the deposition tube (16) containing the silicon wafers. Tetraethoxysilane is vapourised and flowed into the deposition tube (16) where is pyrolyzes on the silicon wafers to deposit silicon dioxide thereon. Product gases and unexpended tetraethoxysilane are drawn out of the deposition tube (16) by the vacuum pump (18). The constant flow of nitrogen provides a ballast effect to regulate the flow of tetraethoxysilane.

Abstract: A multibeam photometric measuring device includes a light assembly (12) comprising a single modulated light source along with a filter assembly (19) for passing only a desired band of wavelengths and an optical system for suitably focusing light from the light source. A fiber rotor arrangement (24) is provided for sequentially connecting the collimated light source to each of the plurality of fibers (34) disposed in a distributor (32). 
     Light passing through the wells of the sample plate (40) is captured by discrete photodetector cells (44) disposed on a one-to-one correspondence opposite the wells of the plate. A reference fiber links (52) light from the light source to a separate photodetector (45) to provide a reference light signal with which the sensed photodetector signals are compared. The sensed signals are suitably multiplexed and processed by circuitry which allows control over the accuracy with which the signals are processed on the basis of their instantaneous strengths as well as reference readings taken during system initialization. 
     Enhancement of colour distribution resulting from chromogenic reactions is provided by automatic agitation by mechanism (54) of the reacting agents within the sample wells before a reading is taken at each of the sampling intervals of a kinetic measurement sequence.

Abstract: The method determines for a predetermined set of characters the hypothesis which most probably caused this set of characters. Starting with the set of permitted hypotheses, a characterising set of characters is allocated to each of these hypotheses, two arbitrary characterising sets of characters generally intersecting. The permitted hypotheses do not have to be mutually exclusive, the characters may occur stochastically dependently and in an uncertainly determined manner. For calculating the probability of a hypothesis, the so-called L theorem is used. The product or compound probabilities required for this must be obtained from sufficiently large representative samples. To facilitate this task, the L theorem can be reformed in such a manner that essentially only conditional probabilities are needed. Apart from an error calculation, the method additionally mainly provides the possibility of excluding falsely determined characters or character-like observations which have no further relevance from the character set present for assessment. The final determination of the most probable hypothesis is made possible by a graphic representation, the hypotheses being arranged in a priority order on the basis of their probability value achieved and on the basis of their spacing from one another.

Abstract: The present invention relates to an optical upconverting or downconverting gain or loss modulating mixer and a receiver for subcarrier optical communication systems using the mixer. The optical mixer can be formed, for example, from an optical amplifier (10) including a semiconductor laser chip comprising p-n junction with an active region channel formed along the junction. An optical signal (L(t)) received from the communication system is directed into one end of the channel, and a combination of a D-C bias signal (25) and a local oscillator signal (27) is concurrently impressed on the chip to gain-modulate the received optical signal and produce an upconverted or downconverted output signal. In the receiver (11), the upconverted or downconverted output signal from the gain-modulated optical amplifier is detected by a photodetector (12), amplified if necessary, filtered and then demodulated before transmission to the output utilization device. A loss modulator (30) provides similar optical mixing but does not provide a gain to the output signal.

Abstract: The method involves co-extruding two differently coloured melt streams. For this purpose, the first melt stream is spread out transversely to the conveying direction, i.e. in the width direction, and united at a number of points with the second melt stream, which has previously been divided into a number of individual melt streams. From the unifying points, irregularly shaped manifolds and/or spiders extend, which have the effect of inhomogeneous mixing of the differently coloured melts at the surface of the unified melt stream. By surging or pulsating control of one of the melt streams, a wood grain effect very similar to natural wood is achieved. Preferred field of application of the invention is the surface coating of window sections by co-extrusion. <IMAGE>
