The method and apparatus for processing pixel output signals from column lines in an imager having an array of pixels in rows and columns uses a sigma-delta type analog-to-digital converter to convert the output signals on each column line to digital signals and feeding them to a digital signal processor. The converter is monitored to stop sampling of a pixel with the detection of pixel saturation...

A Fibre-based optical source comprises a high power laser diode stack as a pump source, the output of which is shaped into an intense beam of elongate cross-section by use of focusing and light concentrating elements. The beam is used to cladding pump a fibre having an inner cladding also with elongate cross-section, to provide high efficiency pumping. To achieve high output powers with a good mod...

The invention relates to a fluidized-bed reactor for the production of trichlorosilane by reacting silicon with silicon tetrachloride, hydrogen and optionally hydrogen chloride at a high pressure and high temperature. According to the invention, the fluidized-bed reactor, at least on the surface facing towards the reaction chamber, is made of a nickel-chrome-molybdenum-(NiCrMo)-alloy with a chrome...

A stretch film presenting controlled permeability to gases, manufactured by process of balloon co-extrusion and consisting of outer layers (S 2 ) of stretchable polmeric material and by one or two inner barrier layers (S 3 ) of a EVOH based polymeric matrix, which is made stretchable by the addition of a suitable plasticizer in such a percentage as to conciliate the stretchablity with the desired ...

Signal elements are mapped to a limited range of identifiers by emulating a "virtual" space of identifiers larger than the real limited space of identifiers. The larger virtual identifier space is implemented by an intermediate memory, which provides storage of identifiers assigned from the real space of identifiers. For each signal element to be mapped to an identifier, the intermediate memory is...

In the case of a thick light-absorbing layer 2 , a phenomenon of a decrease in the time resolution occurs. However, when the thickness of the light-absorbing layer 2 is limited, a portion of low electron concentration in one electron group is cut out, and hence overlap regions of adjacent electron concentration distributions decrease. Therefore, by shortening the transit time necessary for the pas...
