20090032062 | Method for precision cleaning and drying flat objects - Cleaning and drying of semiconductor wafers is carried out in a single-chamber type cleaning/drying apparatus for flat objects such as semiconductor wafer, where cleaning is carried out by impinging both sides of the wafer which rotates at a relatively low speed with jets of a washing liquid and where subsequent drying is carried out in the same chamber by increasing the rotation speed of the wafer and supplying an isopropyl-alcohol (IPA) mist onto the wafer from the top of the chamber. After the IPA forms a solution with the residue of water on the wafer, the drying process is accelerated by supplying gaseous nitrogen through nozzles arranged on both side of the coaxial with the wafer center. As a result, the IPA-water solution quickly evaporates without leaving traces of water drops on the dried surface. | 02-05-2009 |
20090032070 | Single-chamber apparatus for precision cleaning and drying of flat objects - A single-chamber type cleaning-drying apparatus for flat objects, such as semiconductor wafers, wherein cleaning is carried out by impinging both sides of the wafer, which rotates at a relatively low speed, with jets of a washing liquid and wherein subsequent drying is carried out in the same chamber by increasing the rotation speed of the wafer and supplying isopropyl-alcohol (IPA) mist onto the wafer from the top of the chamber. After the IPA forms a solution with the residue of water on the wafer, the drying process is accelerated by supplying gaseous nitrogen through nozzles arranged on both sides of the wafer he coaxially with the wafer center. As a result, the IPA-water solution quickly evaporates without leaving traces of water drops on the dried surface. | 02-05-2009 |
20100037932 | SYSTEM FOR SIMULTANEOUS TABBING AND STRINGING OF SOLAR CELLS - A method for stringing photovoltaic (PV) cells together and a system for the combined tabbing and stringing of photovoltaic (PV) cells for assembly into solar cell arrays. Multiple ribbons are first soldered simultaneously (or nearly so) to the front and back surfaces of individual PV cells (tabbing). After tabbing, PV cells are then loaded into a stringer subsystem which solders the front side ribbons of a first PV cell to the back side ribbons of the neighboring PV cell to form strings of PV cells wired in series. The tabber stringer system then loads completed strings into a frame containing a solar cell array being manufactured. The dual-ribbon method of PV cell interconnection reduces the electrical resistance between the cells in a string, thereby raising the solar cell array output power. | 02-18-2010 |
20100319754 | PHOTOVOLTAIC MODULE CONFIGURATION - Improvements for a photovoltaic module (PVM) include the use of a micro-embossed, reflective optical film located in areas of the PVM not covered by the solar cells. The optical film is configured to reflect light incident upon the PVM onto the solar cells and may be formed from a polymeric material. Further enhancements include the use of a compliant heat conducting polymeric film on back sides of the solar cells and a heat conductive polymeric film deposited on an aluminum foil to form a composite film, which effects heat transfer from the solar cell junctions and improves cell efficiency. A top glass with selective frequency and anti-reflective coatings may also be used. Further, improved interconnects for the solar cells eliminate sharp edges, helping to avoid any potential for encapsulant tearing or tab “push-through” and resultant shorting during lamination. | 12-23-2010 |
20110206453 | Kinematic Mount - A kinematic mount is described in which mobile spheroid bodies belonging to one component mate with conical depressions in a second component. The mobility of the spheroid bodies is achieved using round shafts and tight-fitting holes. | 08-25-2011 |
20110247679 | SOLAR RECEIVER - A lightweight reflector with a load bearing structure based on a tensile spoke-wheel. The spoke structure is especially compatible with dish parabolic mirrors, but has utility as a carrier structure for any round functional surface, including flat or slightly-curved mirrors used in central tower solar systems, parabolic dishes for radio telescopes and antennas, and for non-concentrating thin film solar panels. There are no radial members loaded in compression. All the spokes pull the rim inwards, and the rim is compressed in the circumferential direction. The imbalance in spoke tension results from the application of load provides the rigidity of the rim in respect to the hub, both for in-plane and out-of-plane forces. Ribs stiffen the spokes to resist wind and gravity, but are not structurally supported by either the hub or the rim. Lightweight reflector tiles match the wheel structure and create the reflective surface. | 10-13-2011 |
20110290445 | Heat Conveyance and Storage System - A heat conveyance system particularly suitable for solar applications is described, based on the mechanical conveyance of heat-storage solid bodies containing a bulk that is capable of undergoing phase change. | 12-01-2011 |
20120046140 | PLANETARY HARMONIC DIFFERENTIAL TRANSMISSION - Described is a planetary harmonic differential transmission, comprised of a rigid externally-toothed inner sprocket, a rigid internally-toothed outer sprocket, a deformable belt that is toothed on both its internal and external faces, and a set of free-rotating planetary sprockets that are mounted on a rotating carrier cage and cause the belt to progressively engage and disengage from successive portions of the rigid sprockets. The input to the transmission is the relative motion between the carrier cage and the inner sprocket, and the output is the relative motion between the outer sprocket and the inner sprocket, resulting in a differential transmission. | 02-23-2012 |
