摘要： A positive displacement inductive pump includes a central piston formed of a ferromagnetic material having non-ferromagnetic end pistons that extend from each of its opposite ends. Stationary end walls are mounted to opposite ends of a housing and are centrally bored. First and second inductive coils are alternately energized, causing the central piston and the end pistons to conjointly reciprocate within an axial bore and the end wall central bores, respectively. First and second check valves are positioned outboard of each end wall and allow valve-controlled ingress and egress of material into and out of the axial and central bores. The relative diameters of the central piston and the end pistons are changed to control the relationship between the magnetic force applied and the output pressure for a given volume of fluid.

摘要： Flat, insulated, metallic strips ("applicators"), are fixed to the wider sides of each permanent magnet assembly in the channel array of a Magnetohydrodynamic (MHD) Vacuum Pump. Electromagnetic power from an external rf/microwave generator is delivered by an appropriate transmission line to each pair of applicators, providing an rf/microwave electric field, generally parallel to the magnetic field of the magnets, across each channel in the array. As the plasma ions and electrons formed by the rf/microwave field lose energy by collisions with the channel surfaces and by collisions with neutral molecules in the channel, the microwave electric field reheats the plasma throughout its passage through the length of the channel array, increasing plasma density and enabling the use of much longer channels, thus increasing the throughput and compression ratio in the MHD Vacuum Pump.

摘要： A chip device for manipulating an object component is described, in which multiple liquid substances such as reagents required for a series of manipulations on a sample are stably secured in separated states throughout the manipulations within the device. The chip device includes a manipulation chip, magnetic particles, and a magnetic field application means. The manipulation chip includes a substrate, a groove formed in the surface of the substrate, and a manipulation medium accommodated in the groove such that gel phases and aqueous liquid phases are alternately disposed in the longitudinal direction of the groove and are in contact with each other. The magnetic particles are for capturing and carrying the object component. The magnetic field application means is capable of moving the magnetic particles in the longitudinal direction of the groove in the substrate by the application of a magnetic field to the substrate.

摘要： An electrohydrodynamic (EHD) pump increases refrigerant flow rate and the resulting pressure in a vapor compression based cooling system for permitting reduced compressor sizes and power demands. The EHD pump disposes electrodes in a liquid path of the refrigerant flow, and increases fluid flow and resulting pressure by an induced liquid flow between a pair of asymmetric electrodes. Voltage applied to these electrodes results in a conduction pumping mechanism associated with heterocharge layers in the vicinity of the electrodes based on disassociation of a neutral electrolyte species in the refrigerant fluid and recombination of the generated ions. The induced flow draws the liquid due to a net fluid flow toward one of the electrodes based on the asymmetry of the electrode pair. Electrodes are disposed on an inner surface of a refrigerant vessel, in communication with an annular liquid film that forms around the inner circumference in two-phase fluid systems.
