US6661875 B2 カテーテル先端-線ソースCatheter tip x-ray source Spire Corporation Inventor(s):Greenwald, Anton C. ;Halverson, Ward D. Application No. 10/142288, Filed 20020509, Issued 20031209 US.Class: 378119 378121 600433 600435 Int'l Class: G21G00400;   

Abstract: The present invention provides a catheter having an x-ray generator unit at its tip which generates x-ray radiation having a wavelength in a range effective for treating biological tissue. In one embodiment, the x- ray generator unit includes a miniature x-ray generator and a miniature transformer that form, in combination, a monolithic device. The transformer includes a primary winding that receives an input voltage in a range of 100 V to 4 kV from a power source, via a flexible cable that runs from the proximal end of the catheter body to its distal end. The transformer further includes a secondary winding that up-converts the input voltage to generate an output voltage in a range of 10 kV to 40 kV to be applied to a cathode of the x-ray generator. The cathode emits electrons in response to the applied voltage, and an extraction electrode guides the emitted electrons to an anode, which is preferably formed of a high-Z refractory metal. The impact of the electrons with the anode effects generation of x-ray radiation, a portion of which is transmitted via an x-ray transmissive window to the outside environment. One significant advantage of the device of the invention is that by employing a lower voltage in the body of the catheter and confining a higher voltage to a short, rigid section at the distal end of the catheter, the device provides enhanced mechanical flexibility and lowers the likelihood of electrical breakdown.

US6661643 B2 エネルギ・リカバリーをもった純水装置Deionizers with energy recovery Luxon Energy Devices Corporation Inventor(s):Shiue, Lih-Ren ;Sun, Abel ;Shiue, Chia-Chann ;Hsieh, Fei-Chen ;Hsieh, Yu-His ;Jou, Jiung-Jau Application No. 10/273747, Filed 20021018, Issued 20031209 US.Class: 361502 361503 361504 361512 361516 363131 363132 Int'l Class: H01G00900;   

Abstract: Deionizers using the electrode configurations of electrochemical capacitors are described, wherein the deionizing process is called capacitive deionization (CDI). During deionization, a DC electric field is applied to the cells and ions are adsorbed on the electrodes with a potential being developed across the electrodes. As electrosorption reaches a maximum or the cell voltage is built up to the applied voltage, the CDI electrodes are regenerated quickly and quantitatively by energy discharge to storage devices such as supercapacitors. In conjunction with a carousel or Ferris wheel design, the CDI electrodes can simultaneously and continuously undergo deionization and regeneration. By the responsive regeneration, the CDI electrodes can perform direct purification on solutions with salt content higher than seawater. More importantly, electrodes are restored, energy is recovered and contaminants are retained at regeneration, while regeneration requires no chemicals and produces no pollution.

US6660959 B2 炭素ナノチューブを使用するナノ機械加工のためのプロセスProcesses for nanomachining using carbon nanotubes University of Kentucky Research Foundation Inventor(s):Vallance, Robert Ryan ;Rao, Apparao M. ;Menguc, M. Pinar Application No. 10/301053, Filed 20021121, Issued 20031209 US.Class: 21912118 Int'l Class: B23K01500;   

Abstract: Novel methods and devices for nanomachining a desired pattern on a surface of a conductive workpiece are disclosed. In one aspect, the method comprises using an electron beam emitted from one or more nanotubes to evaporate nanoscale quantities of material from the workpiece surface. The surface of the workpiece to be machined may be excited to a threshold energy to reduce the amount of power required to be emitted by the nanotube. In another aspect, a device is described for nanomachining a desired pattern on a surface of a conductive workpiece, comprising a vessel capable of sustaining a vacuum, a leveling support, a nanopositioning stage, and a laser for heating the workpiece. A nanotool is provided comprising at least one nanotube supported on an electrically conductive base, adapted to emit an electron beam for evaporating material from an electrically conductive workpiece.
