Patent EP-0141207-A2 (EP)
Inventor: WERNER WOLFGANG DR-ING
IPC: H01L29/45
Filed: 1984-09-17
Abstract: An npn silicon transistor which can be used either in the upward mode or in the downward mode and which, despite small dimensions, results in a very low base resistance. The n-type region forming its emitter in the downward mode of the transistor is provided with an electrical terminal consisting of two layers. In this connection, the lower layer adjoining the n-type region is provided by an n<+>-doped polycrystalline silicon layer and the upper layer by a connection to one of the metals tantalum, titanium, molybdenum or tungsten. At the same time, the emitter region to be contacted has been produced using the polycrystalline silicon layer of the electrical terminal at a time subsequent to its formation from the two layers, for which purpose the polycrystalline layer of the electrical terminal has been used as a diffusion source. This measure results in very small emitter dimensions, while the metal silicide layer covering the polycrystalline silicon part of the terminal contact ensures a very low resistance Rs. <IMAGE>

Abstract: It is based on sulphonated chlorination products of natural or synthetic higher fatty acid triglycerides in the form of the alkali metal, ammonium or amine salts. The starting materials are products obtained by chlorosulphonation of advantageously fully chlorine-presaturated mixtures of higher C12-24-fatty acid triglycerides and C6-20-fatty acid esters of monohydric C1-3-alcohols or mineral oils and subsequent hydrolysis. The reaction temperature is 20-90 DEG C. By irradiation with UV it is possible to achieve addition of 5-30% by weight of chlorine and 1-20% by weight of SO2Cl groups (ratio Cl<->:SO2Cl<-> = from 0.7:1 to 70:1).

Abstract: An improved apparatus is disclosed which employs hydrostatic bearings for measuring varying density of a fluid, usually of a slurry of coal or minerals, flowing in a transport pipeline. A first pipe section is fixedly interposed in the fluid carrying pipeline. A second or centre pipe section is horizontally mounted within the first pipe section substantially coaxially therewith and to be in fluid communication with the fluid or slurry transporting pipeline whereby the transported fluid flows through the second or centre pipe section. Ends of the second or centre pipe section and adjacent ends of the transport pipe, or of intermediate pipe pieces conventionally coupled to the transport pipe, are machined and configured to be capable of functioning as hydrostatic bearing surfaces in a direction normal to the longitudinal axis of the centre pipe section. A substantially ring-shaped chamber is disposed between the first and second pipe sections into which hydrostatic fluid is pumped under pressure through an inlet port provided in the first pipe section. The hydrostatic fluid flows through suitable ducts inwardly to the hydrostatic bearing surfaces, whereby motion of the centre pipe section is substantially frictionless in the vertical direction. Weight of the centre pipe section and of the fluid contained therein is measured by load cells, or strain gauges or the like. Preferably, the weight is obtained by accurately measuring vertical displacement of the centre pipe section against the force of preloaded tension rods which mount the centre pipe section to the enveloping first pipe section.

Abstract: CO2 and H2CO3 can be added to the drinking water and water for other usage in the household and for small establishments on the one hand and to any irrigation water for house plants floods or hobby gardens on the other hand, in a simple and purposeful manner and in different concentrations. This makes it possible, on the one hand, to use relatively large, commercially available normal compressed CO2 gas cylinders even in the household and small establishments and to supply the various CO2 users in the household from this compressed gas cylinder. These users can also include domestic appliances for the direct preparation of CO2-containing beverages, the carboniser thereof being connected to the compressed gas cylinder. For the addition of different quantities of CO2, a plurality of mutually independent devices for impregnation of the water with CO2 can also be provided directly before the removal point or the user. The impregnation devices can supply the various lines or appliances in the household in different concentrations via separately controllable devices. As a result, depositions of mineral substances in domestic appliances and machines can be greatly reduced, with economical usage of CO2, and large proportions of the mineral substances present in the drinking water can be utilised for direct absorption by the organism, for example with the drinking water.

Abstract: Before the signals from a number of input lines can be combined into a time-division multiplex, the signals from the input lines generally have to be processed so that for each input line it is necessary to have a circuit, which requires space, and a fairly large number of input lines are thus spatially separated. If the signals from the input lines are immediately combined by appropriately controlled sampling into a time-division multiplex signal of high bit frequency, this signal has to be looped through from input circuit to input circuit, which requires expensive wiring (generally coaxial cable) and very high-speed sampling switches. In accordance with the invention it is proposed to connect a parallel-series converter upstream of the TDM signal output and to pass to this a plurality of bits in parallel from each of the individual inputs, which can be done at an appropriately lower frequency. For this purpose, in each case one bit can be transmitted from a plurality of input lines or each input line is connected to a series-parallel converter, the contents of which are transmitted in parallel to the parallel-series converter. Partial combinations of this are also possible. When a plurality of input lines are combined to one multiplex stage, it is possible to achieve therein a simple address control by means of an appropriate decoder. <IMAGE>
