The present invention comprises a processed thin film substrate () and a method therefore, in order to produce a flexible printed circuit card, having a plurality of microvias going or passing through the thin film substrate and electrically connected along faced-away surfaces, in order to form an electric circuit. A first a number of real nano-tracks are filled with a first material (M), having good electric properties, for the formation of a first number of, here denominated, first vias (V, V, V), that a second number of real nano-tracks are filled with a second material (M), having good electric properties, for the formation of a second number of, here denominated, second vias (V, V, V). The first material (M) and the second material (M) of said first and second vias (V&#x2013;V) are chosen having mutually different thermoelectric properties. A material surface-applied to the thin film substrate, coated on both sides () of the thin film substrate (), is distributed and/or adapted in order to allow the electrical interconnection of first vias, allocated the first material (M), with second vias, allocated the second material (M), and that a first via (V) included in a series connection and a last via (V) included in the series connection are serially co-ordinated in order to form an electric thermocouple () or other circuit arrangement.

A miniaturized X-ray source is disclosed. It comprises an anode structure () and a cathode structure (), each having an essentially pointed portion (), wherein at least the pointed portions being directed towards each other and enclosed in a vacuum cavity (). The anode structure has an essentially dome shaped structure having a first essentially flat part () surrounded by a second essentially flat part (), connected by a wall section (), such that said first and second parts are located at different levels. The pointed portion is provided on said first flat portion and having an extension such that the apex of said pointed portion does not extend beyond the level of said second essentially flat part. A method of making an X-ray source is also disclosed.

The present invention relates to a method for the manufacture of a matrix and to a matrix ( ) thus manufactured, at least one surface section ( ) displaying a microstructure, which matrix ( ) is suitable for inclusion as a mould insert in a mould cavity or in a cavity, in a unit producing plastic components, in order to assign said plastic components an opposing micostructure in a corresponding surface section. An original ( ) with a surface section ( ) displaying a microstructure less than 500 &mgr;m is used in order to apply on this original layer upon layer of a material ( ) and/or mixtures of material producing a matrix, and thereafter the matrix ( ) is removed from said original ( ) or the material in the original is removed. A first layer of material ( ) applied on the original ( ) so that together with a number of additional layers of material, said matrix is formed, is selected having exceptionally good properties as regards the ability of the plastic component to release from the matrix after moulding, curing or polymerisation of the plastic material used, and exceptionally good properties as regards retaining the pattern on the microstructured surface section.

An X-ray source includes a first support member and a second support member joined together so as to form a cavity between them and such that they are electrically insulated from each other. A cathode and an anode are located inside the cavity and opposite each other. The cathode is suitably made of diamond or diamond like material, and includes at least one pointed element.
