A component for the transmission of electromagnetic waves and a method for producing such a component is provided, whereby conductors of a coplanar waveguide system are embedded in a membrane such that they are at least partially suspended across a back-etched area of the substrate for the decoupling of the conductors from the substrate (1). An additional substrate is connected to the bottom side of the back-etched area of the substrate in such a way that a hollow cavity is formed.

A device and a method for producing such a device is provided, whereby the windings of a spiral inductance are embedded in a membrane such that they are freely suspended over a completely back-etched area of the substrate for a decoupling of the windings from the substrate. An additional substrate is connected to the bottom side of the back-etched area of the processed substrate such that a hollow cavity is formed for a decoupling of the windings from the substrate.

A tire sensor module having a circuit carrier, on or in which at least one sensor element is attached for measuring a measured variable, an antenna for transmitting sensor signals to a receiving unit of the vehicle, and a housing, in whose housing inner chamber the circuit carrier is received, the antenna being provided in the housing material of the housing or on a housing side of the housing.

A permanent magnet rotor having a shaft, a hollow cylindrical permanent magnet and an elastic connecting medium between the shaft and the permanent magnet. The permanent magnet is arranged co-axially around the shaft to ensure that the permanent magnet is mounted securely, that it is not damaged during large temperature fluctuations, and that it is not deflected impermissibly from the axis of rotation in case of heavy radial load. A simple installation process uses a mechanical connection between the shaft and the permanent magnet. This task is performed by virtue of the fact that an elastic connecting medium is arranged along the periphery of the shaft at several first areas in which the distance between the shaft and the permanent magnet is enlarged. These first areas are separated from the second areas in which the distance between the shaft and the permanent magnet is minimized but not zero.

A process for preparation of ceftiofur of formula (I)having purity greater than 97% is disclosed. The process comprises reacting [2-(2-aminothiazol-4-yl)]-2-syn-methoxyimino acetic acid-2-benzothiazolyl thioester of formula (II),with 7-amino-3-(2-furanylcarbonylthiomethyl)-3-cephem-4-carboxylic acid of formula (III)in the presence of a mixture of an water-immiscible inert organic solvent and water and in the presence of a organic base and isolating ceftiofur of formula (I) substantially free of impurities by,a) adding water to the reaction mixture and selectively partitioning the impurities in the organic phase and ceftiofur (I) in the form of a salt with the base in the aqueous phase,b) acidifying the aqueous phase containing ceftiofur (I) in the form of a salt with the base in the presence of a mixture containing a water-miscible and a water-immiscible organic solvent and in the presence of a saturated aqueous solution of an alkali or alkaline earth containing salt, to partition ceftiofur (I) in the organic phase, andc) isolating ceftiofur (I) of high purity and substantially free of impurities by evaporation of the organic solvent or precipitation by addition of a anti-solvent.

A component having a robust, but acoustically sensitive microphone structure is provided and a simple and cost-effective method for its production. This microphone structure includes an acoustically active diaphragm, which functions as deflectable electrode of a microphone capacitor, a stationary, acoustically permeable counter element, which functions as counter electrode of the microphone capacitor, and an arrangement for detecting and analyzing the capacitance changes of the microphone capacitor. The diaphragm is realized in a diaphragm layer above the semiconductor substrate of the component and covers a sound opening in the substrate rear. The counter element is developed in a further layer above the diaphragm. This further layer generally extends across the entire component surface and compensates level differences, so that the entire component surface is largely planar according to this additional layer. This allows a foil to be applied on the layer configuration of the microphone structures exposed in the wafer composite, which makes it possible to dice up the components in a standard sawing process.

A mask is used to make an article having two or more layers. The layers are formed from either a paint or polyurethane elastomer composition. The article is made in a mold including a surface defining a mold cavity and having a first and second effect region. For the method, a mask is placed into the mold cavity adjacent the first effect region. Pressure is applied to the mask to retain the mask adjacent the first effect region. A first composition is applied into the mold cavity to form a first layer adjacent the second effect region. The mask is removed from the first effect region. A second composition is applied into the mold cavity to form a second layer adjacent the first effect region. Benefits of pressure applied to a mask are also realized when making the article from a preformed part using the mask outside of a mold.

An interior space of the at least one housing of a force-measuring device is filled with a gas composition that is distinguishable in at least one parameter from the ambient atmosphere. A sensor that is arranged in the interior space, or on the housing, measures this distinguishable parameter. A processing unit of the force-measuring device compares signals obtained from the sensor to monitor and determine the condition of the force-measuring device.
