A method of selectively metallizing a thermoplastic substrate using a hot foil embossing technique, a patterned metal layer being transferred to the substrate from a metal foil by a cutting and pressing procedure including steps (a) and (b). In step (a) the patterned metal layer is first cut from the foil using a punch-press at a selected pressure p.sub.a. In step (b) the cut patterned metal layer is then attached to the substrate using a press at a pressure p.sub.b which is .ltoreq.10 N/mm.sup.2 and also &lt;p.sub.a, and a temperature T.sub.b .gtoreq.100.degree. C. This avoids concurrent application of high pressure and high temperature, which could cause formation of upset edges at the surface of the substrate.

A method of selectively metallising an inner, electrically insulating surface S.sub.i of an open body (3), comprising the following steps:

Method of selectively metallising an inner, electrically insulating

A superconductive thin layer of an oxidic material is manufactured by contacting at least two starting substtances with each other, after which diffusion and a chemical reaction in the solid state occur by means of increasing the temperature, while forming the superconductive thin layer.

Method of forming oxide superconducting layers by solid state diffusion

A method of manufacturing a wire of superconducting oxidic material, in which a preform is used, which includes dispersions of a superconducting material and of a non-superconducting material in a binder or which includes dispersions of non-superconducting materials in a binder, in which latter case the materials can react while forming a superconducting compound, in which the preform is extruded to a wire, the binder is baked out and the wire is sintered.

Method of manufacturing a superconducting wire

A temperature sensor comprises a thin layer of material the composition of which varies gradually over the layer thickness. The material is superconductive below a critical temperature the value of which depends on the composition of the material. The layer is connected, by means of electrodes to an electronic circuit for supplying current to the sensor and processing a temperature-dependent signal produced by the sensor.
