20110011129 | METHOD FOR RECYCLING SILANE (SiH4) - The invention relates to a method for recycling silane that comprises the following consecutive steps: a) injecting a mixture of pure silane/pure hydrogen (SiH4/H2) in a reaction chamber for making silicon-containing thin layers; b) extracting from the mixture the excess of silane not used during step a)/hydrogen (SiH4/H2) via a pump using a supply gas; c) discharging from said pump, at a pressure close to the atmospheric pressure, a mixture containing at least silane (SiH4), hydrogen (H2) and an amount different from zero of said supply gas; d) separating the silane (SiH4) from the hydrogen/supply gas mixture resulting from the mixture from step c), the silane thus obtained containing less than 100 ppm of supply gas, preferably less than 10 ppm of supply gas and more preferably less than 1 ppm of supply gas; characterised in that at least 50%, preferably 70%, and more preferably 80% of the silane (SiH4) from step b) is reused after step d) for a new step a). | 01-20-2011 |
20130000332 | Method and Equipment for Pulsed Charge Refrigeration - The invention relates to a method and device for pulsed charge refrigeration of a member from a Tokamak. The method uses a refrigeration device that subjects a working fluid such as helium to a work cycle comprising: compression, cooling, and decompression, as well as heat exchange with the member and heating. The refrigeration power produced by the refrigeration device is increased to a relatively high level when the Tokamak is in a plasma generation phase, and the refrigeration power produced by the refrigeration device is decreased to a relatively low level when the Tokamak is no longer in a plasma generation phase. Said method is characterized in that the increase in refrigeration power produced by the refrigeration device is automatically triggered in response to a signal produced during a step for starting plasma in the Tokamak. | 01-03-2013 |
20130014518 | Refrigeration Method and Apparatus with a Pulsating LoadAANM Aigouy; GeraldAACI La Croix De La RochetteAACO FRAAGP Aigouy; Gerald La Croix De La Rochette FRAANM Briend; PierreAACI SeyssinetAACO FRAAGP Briend; Pierre Seyssinet FRAANM Deschildre; CindyAACI SassenageAACO FRAAGP Deschildre; Cindy Sassenage FRAANM Fauve; EricAACI BolleneAACO FRAAGP Fauve; Eric Bollene FRAANM Bernhardt; Jean-MarcAACI La BuisseAACO FRAAGP Bernhardt; Jean-Marc La Buisse FRAANM Delcayre; FranckAACI River Sur FureAACO FRAAGP Delcayre; Franck River Sur Fure FR - A method for the pulsating load refrigeration of a component of a Tokamak, said method using a refrigeration device subjecting a working fluid such as helium to a working cycle, the Tokamak comprising at least one operating mode called “periodic and symmetrical,” according to the method, the refrigerating power produced by the refrigeration device being increased to a relatively high level when the Tokamak is in a plasma generating phase (Dp) whereas the refrigerating power produced by the refrigeration device is reduced to a relatively low level when the Tokamak is no longer in a plasma generating phase (Dnp), characterized in that during the “periodic and symmetrical” operating phase of the Tokamak, the refrigerating power of the refrigeration device is regulated according to a forced variation also of the “periodic and symmetrical” type, that is one wherein the respective durations of generation of a high level of refrigeration and of generation of a low level of refrigerating power differ at most by 30%, and in that the variation in refrigerating power brings about gradual increases and reductions in refrigerating power, and in that the increase in refrigerating power produced by the refrigeration device is triggered in advance, in response to a signal (S) generated during a plasma starting step in the Tokamak, that is before the thermal load on the component increases. | 01-17-2013 |
