Title: Process for producing a semiconductor component having patterns produced by reactive etching
Inventor: KATZSCHNER WERNER DIPL ING
IPC: H01L21/306
Filed: 1983-12-06
Abstract: The patterns are to be produced in III-V material, for example InP, GaAs and their ternary and quaternary compounds. For this purpose, dry etching using accelerated ions is of particular importance, in particular for the micrometer and submicrometer range (RIE = reactive ion etching; RIBE = reactive ion beam etching). Mirror quality is required for the etched areas. For this purpose, according to the invention, a gas mixture composed only of argon and oxygen is used as etching gas. The selectivity with respect to normal photoresists does not in this case require additional metal masking. Aggressive deposits which may result in subsequent corrosion are also avoided. Normal systems are readily suitable; requirements relating to safety, environmental pollution and the like are reduced.

Title: Method of determining the gas content of metals and metal alloys and device for carrying out the method
Inventor: KUNIN LEV LAZAREVIC
IPC: G01N27/26
Filed: 1983-12-29
Abstract: In a method of determining the gas content of metals and metal alloys, the reduction melting is carried out using an electrochemical cell made of a solid electrolyte having an ion conductivity in relation to the gas to be determined. The reducing agent used is an electrical current which flows through the cell and whose steady-state value is measured before reduction melting starts. The sample of the material to be examined is then introduced, the change in the magnitude of the electrical current flowing through the cell is registered until it reaches the original steady-state value, and the gas content of the sample is assessed from the current curve. The appropriate device comprises a hermetically sealed working chamber containing a melting crucible (40), a lock (5) for introducing the samples (6) to be analysed into the crucible (40), a heater and a unit for registering the content of the gas in the sample to be analysed. The working chamber accommodates an electrochemical cell formed as a vessel (30) made of a solid electrolyte. <IMAGE>

Title: Process for printing with reactive and disperse dyes
Inventor: ROTH KURT
IPC: D06P5/28
Filed: 1984-08-16
Abstract: Difficulties occurring in practice in the direct printing of blended materials composed of keratin and cellulose fibres with reactive dyes and of blended materials composed of polyester and keratin fibres with mixtures of disperse and reactive dyes, which hitherto stood in the way of a satisfactory shade-in-shade dyeing of the two fibre components, are eliminated by addition of ethoxylated fatty acid amides to the printing paste or appropriate preparation of the material before printing. In an analogous manner, the colouring of a discharge article on blended materials composed of polyester and keratin fibres is favoured by the fatty acid amide ethoxylates.

Title: Constant-voltage asynchronous generator
Inventor: NAGY ISTVAN
IPC: H02P9/30
Filed: 1984-08-16
Abstract: The invention relates to the maintenance of a constant output voltage in the case of capacitor-energised single-phase and three-phase asynchronous generators having a variable magnetic reluctance in the stator laminate stack, by means of a voltage regulator which consists of controllable semiconductors. The voltage regulator is supplied with the alternating current from the main winding of the generator stator. After conversion, the direct current is used for supplying the annular harness regulating winding which is fitted in the stator yoke. Variable loads on the generator, accompanied by voltage fluctuations, are detected by the regulator amplifier and zener diode which is fitted in a suitable manner. Triggering-pulse shifts are derived from the comparison of the actual voltages and desired voltages. These shifts are used for controlling the DC voltage and hence the current and flux-density changes in the harness regulating winding. This solution leads to conformity with a tolerance band of +/- 0.5%, with respect to the adjustable output voltage. The voltage peaks at the output of the generator, caused by the controllable semiconductors, are suppressed by the connection of the voltage regulator being derived from the interior of the main winding of the generator. Possibilities for the structural laying of the harness regulating winding, for example in Protection Type IP 23 and IP 44, are likewise given. Shorts between windings are eliminated by the use of the harness regulating winding. As a result of the correct selection of the ... Original abstract incomplete.

Title: Process for liquefying coal
Inventor: WUERFEL HELMUT DIPL ING DR ING
IPC: C10G1/00
Filed: 1984-10-19
Abstract: In a process for liquefying coal under elevated pressure and at elevated temperature in a reaction zone, it is proposed to feed the reaction product leaving the reaction zone to a coking zone and to cool the gases and vapours arising there, predominantly distillate oil vapours, preferably in direct exchange with the fresh coal paste. The gases and vapours not condensed in this heat exchange are taken off from the plant as end product. By means of the proposed procedure, the oil production is partially displaced from the reaction zone to the coking zone, so that the reaction zone can be operated under a low pressure. Furthermore, a major part of the quantity of exothermic heat generated in the liquefaction reactions can be recycled to the process by the direct heat exchange of the product vapours with the fresh coal paste.

Patent DE-3445963-A1 (DE)
Inventor: HERB ARMIN
IPC: F16B13/10
Filed: 1984-12-17
Abstract: A metal expansion dowel is made up of an axially elongated cylindrically shaped expansion sleeve and an expansion element formed monolithically with the sleeve. The expansion sleeve has a leading end and a trailing end. The sleeve has an opening with the opposite edge surfaces extending in the axial direction converging toward the leading end. The expansion element is located in the opening and is secured to the sleeve by a separable web. The expansion element is wedge-shaped and narrows in the leading end direction. An inwardly projecting stop is formed in the expansion element. When an axial force is directed toward the leading end against the stop, the web is separated from the sleeve and the expansion element is displaced axially toward the leading end of the sleeve moving along the opposite edge surfaces of the opening and widening the sleeve. Due to the converging arrangement of the opposite edge surfaces of the recess, the dowel has a post-expansion characteristic during subsequent axial loading of the expansion sleeve after it is anchored in place.
Patent DE-3446318-A1 (DE)
Title: Elastomer clamping technology
Inventor: MENKHOFF KARLHEINZ
IPC: B25B5/06
Filed: 1984-12-19
Abstract: The invention relates to a clamping system in which a thrust or pull piston is prestressed under high pressure by a compressible elastomer and retains the clamping force under this high pressure over a relatively long re-tightening displacement. The prestressing pressure can be produced, for example, via a pressure screw to be operated mechanically or else with a high-pressure pump. In clamping elements which are to constantly clamp and release, the clamping pressure, which is produced by the prestressed compressible elastomer, can be eased hydraulically, for example, and can come into full effect again after the hydraulic pressure drops. These clamping elements have the advantage that the clamping force caused by the prestressed compressible elastomer is constantly available and keeps a clamped tool or rope, for example, clamped until the clamping force is neutralised mechanically or, for example, by oil pressure.
