摘要:
The invention relates to an electronic device including electric connections extending along at least two different directions, said connections being essentially formed by means of bundles of carbon nanotubes (CNT) (8), Where at least two CNT bundles comprise a portion (8a) having its axis directed along a first direction and a portion (8b) having its axis redirected along a second direction, the connections between CNT bundles being achieved by overlapping of the portions (8b) of said at least two bundles to form a connection line (4).

A microfluidic component comprises at least one channel (2) delineated by a top wall (6) and a bottom wall (3) and two opposite side walls (4, 5). The distance (P) between the top wall (6) and the bottom wall (3) of the channel (2) is greater than or equal to 25 micrometers and first and second sets of nanotubes (9a, 9b) are respectively borne by the two opposite side walls (4, 5) for the component to present a particularly high ratio between the contact surface and the available volume and a limited overall surface size. In addition, the distance between the two opposite side walls (4, 5) is about a few micrometers and preferably comprised between 3 and 5 micrometers.

The data recording device comprises a network of carbon nanotubes formed on a flat substrate and constituting microtips operating in conjunction with a substantially flat storage medium. The carbon nanotubes are initially inclined by a predetermined angle comprised between 5° and 40° with respect to the plane of the substrate. The nanotubes flex when they come into contact with the storage medium, parallel to the substrate. The substrate preferably comprises a raised structure designed to act as support for the free ends of the nanotubes to bear on.

Device and method for testing an optical element (E) to determine ability to withstand heating by a high-energy luminous beam. The contact of a point (11) is applied to the optical element and is heated to a specific temperature to simulate radiation. The contact point includes a dog point having a sectional configuration similar to a track of a simulated radiation beam. The heat can be adjusted and the temperature sensed.

Ferroelectric liquid crystal screen with opacified electrodes in the non-switchable area of the screen and processes for obtaining spacers and treating said screen.On each part of each row or column electrode of the screen, facing a gap separating two column or row electrodes is arranged an element (40,50) preventing the passage through the screen of light reaching the latter in the direction of the element. The elements located on the row electrodes (32) or those located on the column electrodes (34) also permit the spacing, without electrical connection, of the screen plates and the localization of the zigzag defects which the liquid crystal may have, in or in the vicinity of the non-switchable area of the screen. The screen is appropriately heated and an alternating voltage is applied between the electrodes in order to localize the zigzag defects of the liquid crystal in the vicinity of the spacing elements. In order to obtain the latter, it is possible to irradiate a positive resin layer through the plate intended to carry these elements and previously provided with opaque layers on the parts corresponding thereto.
