An automatic phase detection circuit for generating an internal synchronization signal when two clock input signals achieve a certain phase relationship. The hydride-based solid material is mechanically processed in the presence of a catalyst to obtain pure gaseous hydrogen. A molded handle insert is attached to the ends of the tray to provide the multiple utility of reducing the number of handles required, maximizing space utilization, providing a comfortable gripping surface on the outside and inside of the tray, and providing stackability.
