Abstract: The invention relates to fine-particled alkaline-earth titanates and to a method for the production thereof by reacting alkaline-earth metal compounds with titanium dioxide particles. The titanium dioxide particles have a BET-surface greater than 50 m2/g. The titanium dioxide particles can have a very low sulphate, chloride and carbon content. The reaction can take place at a temperature below 700° C. The alkaline-earth titanate can have a BET-surface of 5-100 m2/g. Advantageously, it does not contain any hydroxyl groups in the crystal lattice. The alkaline-earth titanate can be used in the production of microelectronic components.

Abstract: A material which has a high removal rate with a simultaneously gentle polishing behavior is to be made available with a composition in the form of a dispersion or a slurry for the chemical-mechanical polishing (CMP) in the production of electronic or microelectronic components, in particular, semiconductor elements, and/or a mechanical component, in particular, a microelectromechanical component or semiconductor element (MEMS).

Abstract: The invention relates to a heading gas injection system (HGIS) direct injection system. The invention makes it possible to atomize fuel mixtures and fuels of all types and to directly inject them into the combustion chamber of a mixture-compressing, spark-ignition internal combustion engine of all designs. This is achieved by means of a heating element (10), a fuel injection nozzle (1) a temperature probe (5), electrical heating resistors (diodes) (2), an electromagnetic valve (3) and a pressure gauge (14). The control unit (8) is provided for controlling these individual components. This control unit (8) also has the task of ensuring that the inlet valve (4), with the flow meter (6), ensures an optimal pollutant-free and low-pollutant operation. A pollutant-free operation of an internal combustion engine can be ensured when using methanol, ethanol, water mixture, hereby signifying a zero pollutant emission.

Abstract: A table with a movable working surface is supported on a table frame with legs. A running rail arrangement is provided on the table frame and cooperates in a form fitting relationship with a pair of edge rails extending from the working surface. The running rail arrangement is divided into two running rail elements. A first running rail element is rigidly fixed to the table frame. A second running rail element is rotatably mounted to the table frame at a location adjacent to the first running rail element. The first running rail element has a sloped bearing surface on which the second running rail element is supported when the working surface is in a horizontal position. Each edge rail includes a holding and sliding element for supporting the second rail running element. During usage of the work surface, the holding and sliding element is located either under the first running rail element or is supported on the sloped bearing surface of the first running rail element.
