| 20110274549 | BLADE HAVING ASYMMETRICAL MID-SPAN STRUCTURE PORTIONS AND RELATED BLADED WHEEL STRUCTURE - A blade includes a body including an airfoil section, a root at an end of the body for coupling the blade to a hub, a first mid-span structure portion extending from the body, and a second mid-span structure portion extending from the body. The first and second mid-span structure portions extend from the body in an asymmetrical manner. A structure includes a bladed wheel including a plurality of circumferentially spaced blades extending from a hub, and a set of mid-span structures coupling adjacent blades of the plurality of circumferentially spaced blades. The set of mid-span structures are positioned in a non-uniform radial position arrangement. | 11-10-2011 |

| 20090040492 | Lithographic apparatus and device manufacturing method - A source configured to generate radiation for a lithographic apparatus is disclosed. The source includes an anode, and a cathode. The cathode and the anode are configured to create a discharge in a fuel in a discharge space between the anode and the cathode so as to generate a plasma, the cathode and the anode positioned relative to each other so that, in use, current lines extending between the anode and the cathode are substantially curved so as to create a force that substantially radially compresses the plasma only in a region proximate an upper surface of the cathode or of the anode. | 02-12-2009 |

| 20100046789 | METHOD FOR CONVERTING ELECTRIC SIGNALS INTO ACOUSTIC OSCILLATIONS AND AN ELECTRIC GAS-KINETIC TRANSDUCER - The invention relates to electroacoustic engineering, in particular to methods for converting electric signals into acoustic oscillations and to electroacoustic transducers. The method for converting electric signals into acoustic oscillations comprises exposing an oscillating system that is a gas medium pre-structured by a static electric field to an electric/electromagnetic field modulated in strength by an alternating electric signal in accordance with the shape and frequency of the modulating signal, and converting the energy of the field into acoustic energy to be released thereupon into the ambient. An electric gas-kinetic transducer developed to perform this method comprises a dielectric working element and at least two current-conducting plates that can be connected to the pole terminals of a direct voltage source and to a source of alternating electric signals. The operating principle of the transducer consists in converting the energy of the electric/electromagnetic field into the kinetic energy of gas, and then the kinetic energy of gas into acoustic radiation. This work is performed by gas filling nano/micro-sized channels of the capillary pore matrix of the working element under the effect of the external electric/electromagnetic field. An electric signal is converted into acoustic oscillations without involving mechanical intermediary devices, making it possible to avoid amplitude-phase and amplitude-frequency distortions and to reach a matching between the properties of the oscillating system, or a pre-structured gas medium, and the properties of the transmitting medium, or air, thereby improving the efficiency of conversion. | 02-25-2010 |
