  • Publication number: 20120312035
    Abstract: An air conditioning system (10) using a refrigerant fluid (102) and a cooling liquid, the air conditioning system (10) comprising: a first compartment (22) defining a first air inlet (31) and a first air outlet (33) and a first ventilator (28) for creating a first air flow (35) through the first compartment (22) from the first air inlet (31) to the first air outlet (33); a first heat exchange unit (16) provided in the first compartment (22) for allowing heat exchange between the refrigerant fluid (102) and the first air flow (35) when the refrigerant fluid (102) is circulated through the first heat exchange unit (16); a second heat exchange unit (14) also provided in the first compartment (22) for allowing heat exchange between the refrigerant fluid (102) and the first air flow (35) when the refrigerant fluid (102) is circulated through the second heat exchange unit (14), the second heat exchange unit (14) being provided downstream from the first heat exchange unit (16) relatively to the first air flow (35),

  • Patent number: 3979235
    Abstract: A method of providing doped material on a substrate by chemical vapour deposition using a reactive gas.Variations in the doping level are obtained by displacing the doping source along a flow of non-reactive gas having a constant supply in order to vary the amounts of dopant converted to the vapour phase due to retrodiffusion of reactive vapours towards the doping source.Application to semiconductor devices in particular of the III-V type, especially for high-frequency devices.
