Patent CA-1317202-C (CA)
Inventor: KAWASAKI AKIHISA
IPC: H01L21/208
Filed: 1986-11-19
Granted: 1993-05-04
Abstract: ABSTRACT OF THE DISCLOSURE A method and apparatus for drawing up a single crystal using a double-crucible apparatus and a liquid capsule process.  The inner crucible of the double-crucible apparatus is attached to the outer crucible.  The presence of through holes in the lower portions of the inner crucible allow communication between the molten raw material in the inner and outer crucibles.  Through holes in the upper portion of the inner crucible allow communication between the liquid sealing agent covering the molten raw material in the inner and outer crucibles.  Single crystals having uniform impurity concentration and few defects are rapidly grown because the interface between the liquid sealing agent and molten raw material in the inner crucible is even with the same interface in the outer crucible.

Title: Method for operating a fuel cell on carbon monoxide containing fuel gas
Inventor: WATKINS DAVID S
IPC: H01M8/1039
Filed: 1988-06-09
Granted: 1992-07-14
Abstract: ABSTRACT           The invention disclosed relates to a method for operating a low-temperature fuel cell on a fuel gas mixture containing carbon monoxide.  The gas mixture is mixed with an oxygen-containing gas, such as air, in a molar ratio of oxygen to carbon monoxide of about 0.5 to 3:1.  The resulting gas mixture is then contacted with a catalyst, such as platinum, at a reaction temperature of about 10 to 160°C and pressure of about atmospheric to 500 psig.  Under these conditions selective oxidation of the carbon monoxide occurs.  This novel method permits the use of carbon monoxide-containing fuel gases in low temperature fuel cells employing platinum group metal electrodes without poisoning the electrodes.
