In a method for producing a protective cover for a device which is formed in a substrate, a first cover layer is initially deposited on the substrate, the first cover layer covering an area of the substrate which includes the device. Subsequently, an opening is formed in the first cover layer, the opening exposing that area of the substrate which includes the device. Then the opening formed in the first cover layer is filled up using a filling material. Subsequently, a second cover layer is deposited on the first cover layer and in the opening of the first cover layer which is filled up with the filling material. Thereafter, an opening is formed in the second cover layer to expose an area of the filling material. Finally, the filling material covering that area of the substrate which includes the device is removed, and the opening formed in the second cover layer is closed.

In an SOI substrate, an active zone is completely surrounded by a trench filled with insulating material. Disposed adjacent to the trench is a first doped zone which is formed, in particular, by out-diffusion from a doped layer disposed on the wall of the trench. The first doped zone and a second doped zone form a p-n junction of a photodiode.

Laser light of different wavelength can be produced by exciting sparingly water soluble fluorescent compounds of which the .alpha..alpha. m value is less than 0,300 and of which the molecular symmetry is either of symmetry group C.sub.s or of a higher symmetry group than this, the fluorophor having to form a rigid system if the compound belongs to symmetry group C.sub.s, the compounds being present in concentrations of between 10.sup..sup.-1 and 10.sup..sup.-5 mol/l in organic solvents.

Apparatus for housing a micromechanical structure, and a method for producing the housing. The apparatus has a substrate having a main side on which the micromechanical structure is formed, a photo-resist material structure surrounding the micromechanical structure to form a cavity together with the substrate between the substrate and the photo-resist material structure, wherein the cavity separates the micromechanical structure and the photo-resist material structure and has an opening, and a closure for closing the opening to close the cavity.

In a method for generating a protective cover for a device, where a substrate is provided, which comprises the device, first, a sacrificial pattern is generated on the substrate. The sacrificial pattern covers at least an area of the substrate, which comprises the device. Then, a polymer layer is deposited, which comprises at least on sacrificial pattern. Then, an opening will be formed in the polymer layer to expose a portion of the sacrificial pattern. Then, the sacrificial pattern will be removed and the formed opening in the polymer layer is closed.

A method of mounting an electronic power component to a cooling element includes finishing at least a bonding area of the cooling element with a finish for use during soldering, forming an indentation in the bonding area of the cooling element, placing adhesive in the indentation, attaching the power component to the cooling element using the adhesive, and thereafter soldering the power component to the cooling element. The finishing melts during soldering and the adhesive prevents shifting of the power component on the cooling element during soldering. Alternatively, the power component is attached to a printed circuit board by adhesive bonding prior to soldering.

The invention relates to a two-chamber bearing, in particular for motor vehicles, which has hydraulic damping, the liquid-filled chambers of which have rubber elastic peripheral walls and are connected to each other by a line which is provided in a rigid intermediate plate. According to the present invention, a so-called active bearing is provided which can be rapidly adapted to the operational conditions in each case by filling the chambers with an electroviscous liquid, the viscosity of which may be controlled by applying an electrical field in the area of the line which passes through the intermediate plate.

The electroviscous suspension is based on a mixture of aqueous silica gel with silicone oil as the liquid phase to which a dispersant is added. The dispersant consists of amino functional or silicon-functional polysiloxanes having a molecular weight above 800. The concentration of the dispersant is from 1 to 30% by weight and preferably from 5 to 20% by weight, based on the silica gel particles. Electroviscous suspensions such as these are distinguished by the fact that they are highly compatible with elastomeric materials, non-sedimenting, non-inflammable and physiologically acceptable. In addition, they are heat- and freeze-resistant over a wide temperature range and are largely unaffected by temperature and pressure in their viscosity.

A multipurpose kitchen machine is proposed which, in order to increase its usefulness, in addition to its working container has at least one inner container insertable into said working container, said inner container increasing the efficiency of food processing, especially for small batches, by adjustment to individual tool shapes, and facilitates separate processing of different food batches. A special lid can be used to seal both the inner container when placed in the working container and both containers individually.

In a method for producing a protective cover for a device formed in a substrate, at first a sacrificial structure is produced on the substrate, wherein the sacrificial structure comprises a first portion covering a first area of the substrate including the device and a second portion extending from the first portion into a second area of the substrate including no device. Then a first cover layer is deposited that encloses the sacrificial structure such that the second portion of the sacrificial structure is at least partially exposed. Then the sacrificial structure is removed, and the structure formed by the removal of the sacrificial structure is closed.
