Title: Procede de placage par morceaux de cellules de microvaisseaux sur greffon vasculaire synthetique et appareil correspondant
Inventor: HU CAN B
IPC: C12N5/08
Filed: 1996-02-01
Abstract: La présente invention concerne un appareil permettant de plaquer par morceaux sur la surface interne de la lumière d'un greffon synthétique des cellules endothéliales de microvaisseaux récoltées et concentrées provenant de tissus adipeux obtenus par liposuccion, ces cellules récoltées étant rassemblées sous forme de 'pastille' de cellules endothéliales isolées en agrégats lâches. Cet appareil comporte un tube de placage pourvu d'une unique paroi externe rigide délimitant une enceinte de placage. Un ensemble filtre permet de mettre en contact avec le greffon la pastille de cellules provenant d'un récipient de traitement. Cet ensemble filtre comporte une série de filtres de finesse croissante qui définissent ensemble une série d'enceintes à écoulement turbulent dans lesquelles les agrégats de cellules trop gros pour passer à travers un filtre donné sont exposés à une turbulence de flux liquide qui est assez efficace pour casser les agrégats. Un ensemble à clapet de non-retour assure un écoulement unidirectionnel du liquide de façon à ce que le placage par morceaux des cellules sur la surface interne du greffon ne soit pas entravé par un éventuel reflux de liquide, et de façon à ce que les cellules plaquées ne soient pas de même délogées du greffon par ce reflux de liquide.

Abstract: Cette invention concerne un dispositif de génération de plasma pouvant être utilisé dans la fabrication de semi-conducteurs. Ce dispositif comporte une première source d'excitation radiofréquence émettant un premier courant d'excitation possédant une première phase et une première amplitude. Le dispositif comporte également une seconde source d'excitation radiofréquence, laquelle émet un second courant d'excitation possédant une seconde phase et une seconde amplitude, ainsi qu'un élément générateur de plasma dont les première et seconde extrémités reçoivent respectivement les premier et second courants d'excitation. Le dispositif décrit dans cette invention comprend, en outre, un circuit de commande possédant une entrée de commande qui reçoit un signal pouvant être modifié par l'utilisateur et indiquant la différence de phase voulue entre la première et la seconde phase. Le circuit de commande réagit à l'entrée de commande et envoie un signal de commande vers la première ou la seconde source d'excitation radiofréquence afin de commander, respectivement, la première ou la seconde phase, ce qui va créer une différence de phase réelle entre les première et seconde phases représentant une approximation sensible de la différence de phase voulue. Ce dispositif se transforme ainsi en un dispositif de couplage essentiellement inducteur lorsque les première et seconde phases sont en phase opposée, tandis qu'il se transforme en un dispositif de couplage essentiellement capacitif lorsque les première et seconde phases sont en phase. Enfin, lorsque les première et seconde phases diffèrent par un angle compris entre les états de phase et de phase opposée, le dispositif se transforme en un dispositif de couplage combiné inducteur et capacitif.

Abstract: A technique for compensating for bias errors that are inevitably introduced in an N-port analog modeformer (14) of the Butler matrix type, used to transform antenna arm signals obtained from a cylindrically symmetrical or spiral antenna (10), to an equal number of more useful mode signals. Corrupted mode signals from the analog modeformer (14) are downshifted in frequency in a coherent receiver processor (18), converted to digital corrupted mode signals in an analog-to-digital converter (22), and then further processed in a bias error reduction processor (26) to produce output signals that are a close approximation of true, uncorrupted mode signals. The bias error reduction processor 26 uses a memory (28) to store matrix quantities obtained from measurements previously made of the analog modeformer (14), and performs an error reduction function by simple matrix manipulations of the digital corrupted mode signals and the matrix quantities stored in the memory (28). The processor (26) may perform the matrix manipulations by calculation or may make use of a look-up table for faster processing.

Abstract: A welding torch which combines features of both laser and plasma-arc
welding torches. A laser beam (114) is directed by an objective lens (112) so that it is co-linear
with the central axis (41) of a plasma-arc torch. The laser beam (114) passes through a planar or
conical cathode electrode (116) placed at the bottom orifice of the torch. A coaxial aperture (117)
having a diameter less than that of the laser beam is drilled into the cathode (116) to allow
the laser beam to pass through the cathode. A constricting nozzle (130) placed under the
cathode (116), with the laser beam passing through the axis of the nozzle. As with standard
plasma-arc torch, a gas is forced through a chamber having the cathode (116) and nozzle (130)
at its bottom end. As the cathode (116) is heated by the laser radiation, the gas is ionized
and a plasma-arc is formed. As the laser beam passes through the nozzle (130), it
comes to a focus and interacts with the plasma-arc formed between the cathode and a
workpiece. The resulting interactions between the plasma-arc and laser beam form a
plasma-laser discharge which acts to additionally constrict the laser beam and plasma-arc
and increase the energy density of the welding spot formed on the workpiece.
