Patent number: 6637379Abstract: A liquid to gas converter to convert liquids (1) to gas (2) that can include a liquid pressurization element (3), a liquid preheating element (5), and a nozzle (10) to disperse liquids into energy (7) generated by an energy source (8). The gas to liquid converter can be located inside an enclosure (17) and substances dissolved in the liquid can accumulate as solids (13) on deposition surface (12) of the enclosure as the liquid (1) converts to gas Cis (2). Condensation of a portion of the gas (2) generated can be combined with the solids (13) for continuous removal of such solids (13) from the enclosure (17). A gas expansion compensator can generate a pressure gradient (24) to move the volume of gas generated from the liquid from the enclosure (17).Type: GrantFiled: October 24, 2002Date of Patent: October 28, 2003Assignee: A.

Patent number: 6612250Abstract: Method of controlling the temperatures of an exothermic process carried out in a suspension of solids in a reactor system formed by a wind box (2), a vertical riser (5), which is essentially not cooled, a particle separator (6), at least one set of recycling channels (9), which are not cooled, and at least one cooled set of recycling channels (12). According to the invention, the flow of solids travelling through the recycling channel (9), which is no cooled, as adjusted based on the temperature difference (T2−T1) between the upper and lower parts of a riser (5), which is not cooled, and the flow of solids travelling through the heat exchanger (12) is adjusted based on the temperature (T1) of the lower part or the temperature (T2) of the upper part of the riser tube. The control of the riser temperature is thus exclusively based on the regenerative heat transfer of the solids returned from the heat exchangers.Type: GrantFiled: April 2, 2002Date of Patent: September 2, 2003Assignee: Einco OyInventors: Seppo Kalervo Ruottu, Lauri Tapio Ruottu

Patent number: 6604493Abstract: A liquid vaporizing and feeding apparatus, having high heat transfer efficiency and capable of producing a large flow of vaporized gas from a small amount of liquid, utilizes an inclined vaporization plate which is held at a set temperature by a heater. Liquid, discharged by a nozzle in the vicinity of the upper end of the vaporization plate, is vaporized as it flows down an inclined upper face of the vaporization plate. When the volume of the liquid collected on the vaporization plate 20 reaches a designated amount, a level sensor 40 stops the inflow of liquid through the nozzle. Then, as vaporization continues, and the liquid level falls, the sensor causes inflow of liquid to resume. The cycle of stopping and resuming flow of liquid is repeated to maintain a constant liquid level.Type: GrantFiled: October 8, 2002Date of Patent: August 12, 2003Assignee: Aera Japan Ltd.Inventor: Ikuo Toki

Patent number: 6572707Abstract: A vaporizer is provided for vaporizing sensitive liquid precursors in semiconductor processing applications. The vaporizer uses high flow conductance with large flow area to avoid precursor decomposition. The vaporizer also uses efficient heat conduction to avoid local cold spots due to the heat loss because of the transformation from the liquid to gas phase. The vaporizer convex surface configuration also allow a more uniform distribution of the vaporized liquid precursor. In some aspects of the invention, the vaporizer distributes the precursor to a larger area, thus eliminating the need for a showerhead.Type: GrantFiled: June 14, 2000Date of Patent: June 3, 2003Assignee: Simplus Systems CorporationInventor: Tue Nguyen
