A method for making a piece of figured veneer comprises softening lignin in a sheet of veneer, and advancing the sheet of veneer between a first roller having a semi-flexible outer surface and a second roller. Once formed, the films, fibres, foams or adhesives are treated to modify the properties of the materials, in particular to improve the wet strength of the materials. At least a part of the surface constituting the exhaust port is formed with a curved surface. A predefined pattern is generated for a write burst to the SDRAM.
