Abstract: The present invention is an apparatus for the synthesis and growth of single crystals of phosphorus compounds starting with the elemental materials in a single furnace without external exposure. The apparatus of the present invention is a crystal growth furnace heated by RF coils. Inside the furnace is a susceptor heated by a lower coil device for holding a crucible. Above the crucible is selectively positioned a phosphorus improved injector. The improved injector is further surrounded by a susceptor which is heated by an upper coil device. The non-phosphorus materials are placed in the crucible and melted to a desired temperature. The phosphorus material previously placed within the injector is heated by the radiant heat from both crucible and the upper susceptor to drive the phosphorus vapor into the melt through a tube. This is closely controlled by noting the temperature within the injector and adjusting the height of the injector above the melt to control the temperature within the phosphorus material.

Abstract: A method and apparatus for printing multiple pages written in page description format on a single sheet. The invention prints the multiple pages onto the single sheet by dynamically fitting the pages into the usable surface area of the sheet. To achieve the best fit, the invention determines a maximum scale factor for the multiple pages printed onto the sheet. This maximum scale factor is approximated by calculating a sheet layout which occupies the greatest percentage of the usable surface area of the sheet. Additionally, the invention provides for printing multiple pages on successive sheets while allowing the user to specify that margins be located on opposite edges of alternate sheets.
