Abstract: A foam air duct for transferring heated or cooled air throughout an automotive vehicle. Material for the foam air duct may be a closed-cell polyolefin foam blend that creates several advantages in automotive HVAC design including reduction in the weight of the foam air duct, flexibility, and reduction in noise, vibrations and harshness (NVH) during operation.

Abstract: A method for applying a flame for depositing a doped layer to a wafer and chuck particularly adapted for suspending the wafer over the flame. The chuck includes a frame having an opening defined by an inner wall for receiving a wafer and a ledge surrounding at least a portion of a lower end of the opening for retaining a wafer placed into an upper end of the opening, and a suspension assembly for suspending the frame over a dopant-depositing flame such that the ledge is disposed between the flame and peripheral portions of the wafer. The inner wall and the ledge may be formed from a material having substantially the same thermal conduction and expansion characteristics as the wafer. The suspension assembly may be rotatable with respect to a dopant-depositing flame. The frame may have a plurality of openings, each for receiving a wafer. The suspension assembly may include a suspension member, and a support post connecting the suspension member to the frame.
