摘要:
A method for producing a semiconductor circuit with several interconnected active and/or passive elements on a substrate having at least one p area and one n area, characterized by the following steps: a) at least one p conducting layered area or an n conducting layered area is produced and another area made of an n conducting or p conducting material is produced thereon; b) metal contacts are applied to the bare surface of the other area, optionally after the structuring of the thus produced structure, according to a selected pattern; c) the surface of the thus produced structure provided with metal contacts is applied to an auxiliary substrate by means of an adhesive; and d) other metal contacts are applied to the thus produced structure on the side of the former substrate after removal of areas of the structure as far as the former metal contacts, according to another selected pattern.
摘要:
The invention relates to thin, flat, porous gas diffusion electrodes comprised of carbon which have a smooth surface and whose porosity can be adjusted according to choice. The inventive electrodes are obtained by pyrolysis of a composite out of an organic aerogel or xerogel and a reinforcing skeleton which is completely or partially comprised of organic material.

摘要:
Die Erfindung betrifft ein Vakuumdämmelement (10) aus einer mit einer ersten Umhüllung (18) gasdicht umhüllten inneren Füllkammer (12) und einer zweiten, äußeren gasdichten Umhüllung (28) die eine oder zwei äußere Füllkammern (32) ausbildet. Die innere Füllkammer (12) enthält ein grobporöses oder grob strukturiertes Dämmmaterial (14), Wasserstoffgas und ein mit Gettermaterial gefülltes Heizelement (16) zur Absorption und Desorption von Wasserstoff und weist eine schaltbare Wärmeleitfähigkeit auf.
摘要:
The invention relates to a method for growing a crystalline structure on a substrate (16) that has an at least partially crystalline surface (40), using a source material (18) that contains at least one element that can be applied to the crystalline surface to from a crystalline structure, whereby the source material is provided in a solid state while the method is carried out and also has a surface extension that corresponds at least substantially to that of the substrate (16), being arranged in an opposite, parallel position thereto, whereby the source material (18) has a larger, effective surface on account of its porosity and/or surface structure than that of the substrate and whereby at least the source material is heated to a temperature below the melting point thereof.
