Abstract: A method includes circulating a heat transferring fluid in a substantially closed system including an interstice between a wafer and a chuck at a first pressure. The method further includes pumping the fluid out of the interstice and increasing the pressure of the fluid to a second pressure. The method further includes reducing the pressure of the fluid to the first pressure and returning the fluid to the interstice. In the system, the fluid in the interstice transfers heat from the wafer to the chuck, or vice versa, by conduction. The presence of a conducting fluid in the interstice thereby decreases the resistivity of the interface, and enables more efficient heat transfer from the wafer to the chuck.

Abstract: An air-conditioning system allows adjustment of the vented air temperature of a rear seat evaporator. An electronic control system judges whether the surface of the rear seat evaporator is frosting up when 1) a target blowing rate of the rear seat blower is lower than a predetermined value, 2) a detected temperature of evaporator vented air is lower than a specified temperature TEa, and 3) a detected temperature of the outside air is lower than a specified temperature TAMa. A target temperature TEO is raised at this time, so that an electric motor of an electric compressor is stopped and refrigerant no longer flows into the rear seat evaporator. The surface temperature of the rear seat evaporator rises so that the rear seat evaporator can be defrosted.

Abstract: At least one model is associated with one or more manipulated variables and one or more controlled variables, which are associated with a cascade liquefied natural gas facility. Adjustments to the one or more manipulated variables are made using the at least one model to maintain the one or more controlled variables within defined limits. For example, a controlled variable may identify an overall load placed on multiple refrigeration systems in the facility. The one or more manipulated variables may be adjusted to increase the overall load placed on the refrigeration systems. The overall load can be determined by identifying a maximum of: a projected feed gas rate to operate a propane refrigeration system at maximum load, a projected feed gas rate to operate an ethylene or ethane refrigeration system at maximum load, and a projected feed gas rate to operate a methane refrigeration system at maximum load.
