摘要:
Screen-printable metallization pastes for forming thin oxide tunnel junctions on the back-side surface of solar cells are disclosed. Interdigitated metal contacts can be deposited on the oxide tunnel junctions to provide all-back metal contact to a solar cell.

Vaporizable material is supported within a vessel to promote contact of an introduced gas with the vaporizable material, and produce a product gas including vaporized material. A heating element supplies heat to a wall of the vessel to heat vaporizable material disposed therein. The vessel may comprise an ampoule having a removable top. Multiple containers defining multiple material support surfaces may be stacked disposed within a vessel in thermal communication with the vessel. A tube may be disposed within the vessel and coupled to a gas inlet. Filters, flow meters, and level sensors may be further provided. Product gas resulting from contact of introduced gas with vaporized material may be delivered to atomic layer deposition (ALD) or similar process equipment. At least a portion of source material including a solid may be dissolved in a solvent, followed by removal of solvent to yield source material (e.g., a metal complex) disposed within the vaporizer.

A system, method, and apparatus for managing a water supply in a water tank are presented herein. A submersible pump is placed inside the water tank. The thrust of the pump causes a considerable increase in water circulation about the water tank, thereby resulting in a more consistent water supply. Chemical disinfectants are added directly in front of the pump, thereby resulting in better mixing. Additionally an outlet from the pump provides a testable sample for measurement of the concentration of the chemical disinfectant. The measurements of the concentration of the chemical disinfectant are provided to a programmable logic controller which makes real time adjustments to the chemical disinfectants that are added.

A chiller tank system for containment of chilled liquids comprises a first tank and a second tank position within the first tank. The first tank is spaced apart from the second tank so that insulation material can be positioned between them The second tank defines a chamber for receiving the liquid to be chilled. A straight-lined, chiller barrel is positioned vertically within the chamber, the chiller barrel defining a bore connected to a flexible, dual hose. The straight-lined chiller barrel extends downward into the tank thereby evenly chilling the liquid to avoid thermal stratification that causes vaporization by creating warm spots within the liquid. A refrigeration unit supplies inert refrigerant to the tank. The dual hose circulates refrigerant between the refrigeration unit and the chiller barrel, the dual hose comprising an inner hose within an outer hose, the outer hose concentric to and spaced apart from the inner hose thereby creating two channels, one for transporting the refrigerant to the chiller barrel and the other for transporting the refrigerant away from the chiller barrel.
摘要:
A method and apparatus for controlling water impurity level and temperature uniformity within large water-containing reservoirs including a pump located in the body of water, the pump ejecting a jet of water therefrom and ingesting water at a point remote from said ejecting and an eductor positioned in the jet of water for pulling in low pressure water and flowing a stream of water therefrom providing mixing and circulation of water within the reservoir to remove temperature gradients. Water purity is controlled by a controller.
摘要:
Coolant (3) whose boiling point is higher than the temperature of cooled SQUID elements (2) as cooled objects is poured into an inner container (37) for containing SQUID elements. The SQUID elements (2) are soaked in the coolant (3). Before the inner container (37) for containing SQUID elements is used, the coolant (3) is cooled and solidified by a refrigerator (7).
摘要:
Provided is a method for charging a powdery heat insulator into a thermally insulated, double-shelled tank between its inner vessel and outer vessel. The method comprises causing a powdery heat insulator to flow together with water into a space between the inner vessel and outer vessel of a thermally insulated, double-shelled tank, discharging the water in said space, and then drying the powdery heat insulator. The pressure in the space is then also reduced. The drying of the powdery heat insulator can be carried out by heating either the inner vessel or outer vessel, or both of these vessels, or by inert gas flow, such as nitrogen gas.
