The present invention provides a method of monitoring performance of a discharge lamp. The discharge lamp includes electrodes and a discharge vessel filled with gas and equipped with a luminescent layer, wherein the gas is intended to emit a first ultraviolet light in a first spectral range when the gas is excited by an electric field produced by the electrodes, and at least part of the first ultraviolet light is intended to be changed into a second ultraviolet light in a second spectral range of longer wavelength than the first spectral range by the luminescent layer. The method comprises the steps of finding the value of a first intensity of the first ultraviolet light; finding the value of a second intensity of the second ultraviolet light; and determining the conversion efficiency of the luminescent layer for converting the first ultraviolet light into the second ultraviolet light on the basis of the ratio of the value of the second intensity to the value of the first intensity.

The present invention is direct to a nano-probe corona tool and uses thereof. A nano-probe corona tool is disclosed having a tip with a diameter in the nano-scale, typically around 100 nm. The nano-probe corona tool is constructed of electrically conductive material. On the other end of the tool, a pulsed voltage source outputs a pulsed voltage to generated a pulsed electrical potential at the tip. The pulsed electrical potential at the tip causes a plasma discharge corona to occur. Uses of the corona discharge include, but are not limited to, optical emission spectroscopy, in the enhancement of deposition of coatings and nanoscale welding, e.g., nanotube or nanowires to a contact pad and welding two nanowires together, and in nanoscale surgery. For example, a nano-probe comprising CNTs may be inserted into cell membranes. The resulting corona discharge may be used to destroy tumors within the cell.

Control data for a main deflector is calculated based on position data that specifies the position of a region to be irradiated with the electron beam on the subfield, data on the number of all beam shots on the subfield, data on a time required for all the beam shots, and stage data that specifies the position of the stage. When the number of beam shots on one of the divided subfield sections reaches the obtained number of the beam shots on each of the divided subfield sections, a writing process proceed to a writing operation to be performed on another one of the divided subfield sections based on the direction of the movement of the stage.

A method for compensating for changes in output power or wavelength of an optical source with temperature. Many optical sources have power and/or wavelength variations with temperature which can be compensated by open- or closed-loop methods if a method of accurately measuring the optical source temperature is available. The voltage across a semiconductor junction varies with temperature. Measuring the optical source power or wavelength variation with temperature and tracking the voltage across the semiconductor junction provides a means for compensating an instrument for temperature induced optical output power or wavelength variations. An important field of application is optical density or turbidity measurements in cellular media.

(The cavity arranged between the central unit (4) and the structured steel blocks (15, 19) has at least two acceleration regions (24, 25), between which there is arranged a magnetic focussing device (17), which focuses the ion beam from one region (24) to the next region (25).)The drift tube accelerator (1) according to the invention has such a stable and massive structure that it requires no external supporting aids of any kind in order to obtain alignment, which is reliable and accurate to a few micrometers, of the acceleration components within the drift tube accelerator (1) with respect to the longitudinal axis (7) of ion beam guidance of the central unit (4). The massive structure of the drift tube accelerator (1) according to the invention can be used in general for any linear accelerator.
摘要:
A charge coupling for an electric vehicle wherein conduction is enabled from a charger to an electric vehicle battery when a supply connector to the charger is completely fitted to a vehicle inlet installed in the electric vehicle. A locking member is provided for temporarily locking the supply connector to the vehicle inlet at a half fitting position, the locking device being further provided with a spiral groove extending from the half fitting position to the complete fitting position. An engagable boss which projects from a distal end of either the vehicle inlet or supply connector is adapted to detachably engage the spiral groove and the supply connector is provided, on its outer periphery, with a handle for assisting rotation of the supply connector so that the engagable boss moves within the spiral groove from an outer end to a terminating end. A holding member is provided on either the vehicle inlet or supply connector and serves to maintain the supply connector at the complete fitting position in the vehicle inlet when the engagable boss reaches the terminating end of the spiral groove.
摘要:
A device for generating and guiding an electric discharge current including a first electrode, second electrode and a material arranged between the first and second electrode. The device uses a laser for generating photons having energies equal to the energy between two excited electronic states of the material. The photons fill a region of the material from the first electrode through the material to the second electrode ionizing the region of the material between the first and second electrodes. A voltage generating unit connected to the first and second electrodes applies a voltage between the first and second electrodes thereby generating the electric discharge which follows an ionized path in the region between the first and second electrodes.
