Abstract: Described herein is an ion pump system implementing an electronic ratchet mechanism produced by modulating a spatially varying electric potential distribution that can result in a net ionic current and voltage. The ion pumping membrane system includes an ion-permeable layer integrated with ion-selective membranes. The electric potential distribution within the ion-permeable layer is modulated through external stimuli. When immersed in solution, ions within the ion-permeable layer experience a time varying, spatially asymmetric electric field distribution resulting in ratchet-driven direction pumping, which can be used in applications such as desalination.

Abstract: A vacuum cell is described. The vacuum cell includes an inner chamber, a buffer channel, and a buffer ion pump. The buffer channel is fluidically isolated from the inner chamber and fluidically isolated from an ambient external to the vacuum cell. The buffer ion pump is fluidically coupled to the buffer channel and fluidically isolated from the ambient and the inner chamber.

Abstract: Within an ion pump, accelerated ions leave the center portion of an anode tube due to the anode tube symmetry and the generally symmetrical electric fields present. The apparent symmetry within the anode tube may be altered by making the anode tube longitudinally segmented and applying independent voltages to each segment. The voltages on two adjacent segments may be time varying at different rates to achieve a rasterizing process.

Abstract: An ion pump includes an evacuateable envelope having a chamber. A first and a second cathode are disposed within the chamber and spaced apart from one another. An anode is spaced apart from and between the first and second cathodes. The anode has an anode body with a textured surface that defines capture regions for fixing material sputtered from the first and second cathodes and controlling size of sputter depositions shed from the anode.

Abstract: Heat transfer devices are based on using one or more ionic pumps to circulate a dielectric working fluid around a closed circulation path, which may be contained in a conduit. The working fluid may be a liquid or a gas. The ionic pumps are disposed along the closed circulation path. The pumps include an emitter and collector. When a voltage is applied to the emitter, the working fluid is ionized at the emitter. The ionized fluid is drawn electrostatically to the lower-voltage collector, which, through collision with molecules that in turn impart their momentum, creates a flow of the working fluid. This approach may be used with either positive or negative corona devices.

Abstract: A rotary electric machine is installed such that a central axis of a rotating shaft is horizontal, and coolant suction apertures are formed at positions on a cylindrical portion of a frame that are vertically above first and second coil ends, and strip-shaped insulating papers are inserted such that a thickness direction is in a radial direction between radially adjacent conductor portions of portions of the conductor wire that constitute the first and second coil ends, and are disposed so as to extend circumferentially across positions that are vertically below the coolant suction apertures inside the first and second coil ends.

Abstract: A jet flow generation device includes: a discharge electrode; a reference electrode that is disposed away from the discharge electrode; a power supply circuit that generates an output voltage to control a potential difference between the discharge electrode and the reference electrode; a controller that switches the output voltage of the power supply circuit between a first voltage that does not induce corona discharge between the discharge electrode and the reference electrode and a second voltage that induces corona discharge between the discharge electrode and the reference electrode; and a case housing at least the reference electrode has an injection port that injects an ion wind of ions generated by the corona discharge.

Abstract: A vacuum exhaust method is for decreasing a pressure in a processing chamber in which a mounting table configured to mount thereon a substrate is provided by using a gas exhaust unit. The vacuum exhaust method includes mounting a non-evaporated getter (NEG) on the mounting table, and adsorbing an active gas in the processing chamber on the NEG mounted on the mounting table. In the adsorbing the active gas, the NEG is maintained at a predetermined temperature.
