A method and apparatus for creating andor using a stamp sheet is described. The control circuit is selectively operable in a working mode in which data in the plurality of SRAM cells can be accessed and a shutdown mode in which the source line is allowed to float to a level that is substantially equal to the first voltage. In particular, a portable vacuum insulated bottle is provide which makes hot water using liquid propane gas as a possible heat source. The present invention comprises a porous plate technique never associated with torpedo design.
