Arrangement for the generation of intensive short-wavelength radiation based on a gas discharge plasma

The invention is directed to an arrangement for the generation of intensive short-wavelength radiation based on a gas discharge plasma. It is the object of the invention to find a novel possibility for generating intensive short-wavelength radiation, particularly EUV radiation, based on a gas discharge plasma which achieves a long life of the electrode system along with a high total efficiency of the radiation source without substantially increasing the dimensions of the discharge unit. This object is met, according to the invention, in that exclusively suitably shaped vacuum insulation areas which have the shape of an annular gap and which are formed depending on the product of gas pressure (p) and interelectrode distance (d) between the cathode and anode are provided for insulating the cathode and anode from one another in a cylindrically symmetric electrode arrangement for reliable suppression of electron arcing.

Egr system for internal combustion engine and method for controlling the same

An EGR system includes a high-pressure EGR passage that provides communication between an exhaust pipe, at a portion upstream of a turbine of a turbocharger, and an intake pipe, at a portion downstream of a compressor; a low-pressure EGR passage that provides communication between the exhaust pipe, at a portion downstream of the turbine, and the intake passage, at a portion upstream of the compressor; and an exhaust gas catalyst provided upstream of a position at which the low-pressure EGR passage is connected to the exhaust pipe. When an internal combustion engine is in the transitional state from the low-load operating state to the high-load operating state (S303), if incomplete combustion is detected in the internal combustion engine (S304) and the bed temperature of the exhaust gas catalyst is lower than the reference temperature (S305), the high-pressure EGR gas amount is made larger than the prescribed high-pressure EGR gas amount determined based on the operating state of the internal combustion engine (S306). Thus, an excessive decrease in the intake air temperature is suppressed, and therefore occurrence of incomplete combustion is suppressed.

Method and apparatus for matching positions of images

InactiveUS6915003B2None of them can perform matchingReliable suppressionImage enhancementImage analysisComputer science
Approximate position matching processing is firstly performed with respect to entire areas of two images of a single same object. Selection is then made to find local area limited regions, between which a degree of shift is high, in the two images, whose positions have been approximately matched with each other by the approximate position matching processing. Position re-matching processing is then performed with respect to at least the local area limited regions, which have thus been selected. The approximate position matching processing may be global position matching processing, local position matching processing, or a combination of the global position matching processing and the local position matching processing.
