  • Method of producing a wall, particularly a wall of a micro heat exchanger, and micro heat exchanger comprising, in particular, nanotubes
    Publication number: 20100018686
    Abstract: Method of producing a wall, in particular a micro heat exchanger for semiconductor devices or microsystems, and micro heat exchanger, in which particles are embedded in a layer, some of which have a part anchored into a wall of said layer and a part projecting from this wall after removal of material.

  • Superconductive device including a supercooled first body heated by electromagnetic radiation at a first frequency and a supercooled second body heated at a second frequency greater than the the first for measuring a magnetic field
    Patent number: 5473249
    Abstract: The device includes a first body (1) of superconducting material placed in the magnetic field to be measured, an arrangement (7) suitable for successively changing the temperature of this first body above and below its transition temperature, at a first frequency, so as to generate field variations in the vicinity of the body, and an arrangement for determining the field from these variations. The arrangement includes a second body (4) of superconducting material, placed in the vicinity of the first body (1), an optical fiber (8) suitable for changing the temperature of at least one portion of this second body, above and below its transition temperature, at a second frequency greater than the first frequency, in order to generate, in this second body, current variations proportional to the field variations. These current variations are then measured and the field is determined from these variations.
