Abstract

A gasifer comprising the size of an opening of the furnace less than the size of a bottom of the furnace, representing the narrow top and wide bottom furnace, with a heating system surrounding around the outer peripheral of the furnace. A heating is performed on the solid ion source. As continuously reducing the solid ion source during the heating, the surface area of the solid/ gaseous interface effectively offsets the reduction of the total amount obtained by the ion implater due to the reduction of the solid ion source.

Claims

exact text as granted — not AI-modified
1 . A gasifier, comprising: 
 a furnace; and    a heating system surrounding around the outer peripheral of the furnace;    characterized by: a size of an opening of the furnace less than a size of a bottom of the furnace.    
   
   
       2 . The gasifier of  claim 1 , wherein the furnace is shaped of a cone.  
   
   
       3 . The gasifier of  claim 1 , wherein the furnace is shaped of an angle cone.
