Single Axis Solar Tracking System
ActiveUS20080308091A1Maximize economic performancePerformance maximizationPhotovoltaic supportsSolar heating energyTerrainWind force
A solar tracking system with a torque tube supporting solar panels. Columns support the system and have bearings for rotation of the torque tube. A drive is coupled to the torque tube and is driven by a gearbox, such as a worm gear assembly, for rotating the array of solar panels to follow the sun's diurnal motion. The array can rotate in an opposite direction, or backtrack, to prevent shadowing from one module row to another. Multiple gearboxes can be mechanically linked by drive shafts and driven by a single motor. The drive shafts may incorporate universal joints for uneven terrain or staggered configurations. Harmonic dampers can be affixed to the solar panels to decouple wind forces which allows the use of larger solar panels.

A semiconductor display device with an interlayer insulating film in which surface levelness is ensured with a limited film formation time, heat treatment for removing moisture does not take long, and moisture in the interlayer insulating film is prevented from escaping into a film or electrode adjacent to the interlayer insulating film. A TFT is formed and then a nitrogen-containing inorganic insulating film that transmits less moisture compared to organic resin film is formed so as to cover the TFT. Next, organic resin including photosensitive acrylic resin is applied and an opening is formed by partially exposing the organic resin film to light. The organic resin film where the opening is formed, is then covered with a nitrogen-containing inorganic insulating film which transmits less moisture than organic resin film does. Thereafter, the gate insulating film and the two layers of the nitrogen-containing inorganic insulating films are partially etched away in the opening of the organic resin film to expose the active layer of the TFT.

A pumping machine, that can serve a system as the sole main pump for pressurizing a primary liquid flow, incorporates, in a single machine, a rotor-drum type AP (axial piston) pump and a PX (pressure exchanger) that recovers energy from a secondary liquid flow such as the brine discharge from an RO seawater desalination system, with benefits including fewer moving parts and small machine size along with lower capital and operating costs. A single rotor-drum containing the cylinders and pistons is located between two end blocks, one or both configured with manifold passageways, ports and sliding valves. A swash-plate at one end reciprocates the pistons axially when the rotor-drum is rotated. Two working chambers, primary and secondary, are formed at opposite ends of a single piston in each cylinder, thus enabling the single rotor-drum to function as a primary liquid-pressurizing axial pump (AP) with sliding valves at the primary end enabling primary liquid pumping, and as a secondary outflow-driven pressure exchanger (PX) recovering energy from pressure drop in the secondary liquid flow and thus contributing work to primary pumping, saving energy and reducing operating costs.
