Abstract: Decorative holographic diffraction grating patterns and methods of creating the same which provide low cost computer generation of two-dimensional holographic patterns and the generation of very large holographic patterns. In accordance with the method, the desired pattern is made up of a large plurality of individual spots, each spot comprising a holographic diffraction grating of a predetermined grating spacing and angular orientation for that spot. Variation of the angular orientation and/or grating spacing between spots and/or groups of spots provide the desired holographic effect. The spot locations may vary as desired, including locations drawing out a desired pattern, and two-dimensional orthogonal matrices in which a pattern is drawn by variations between spots or group of spots as in a raster scan type image. Various embodiments and methods for creating the same are disclosed.

Abstract: In a method of producing a rotary anode of an X-ray tube having a focal track region composed of refractory metals, the focal track region is manufactured by powder-metallurgy methods or by CVD OR PVD methods. According to the invention, the focal track region is aftertreated, preferably using high-energy electrons or photons, at a depth of less than 1.5 mm by means of local superficial melting. This reduces, in particular, the residual porosity of the focal track region, which results in improved mechanical properties, higher X-ray yield and markedly improved service life of such rotary anodes.

Abstract: A high speed soft recovery diode having a large breakdown voltage is disclosed. Anode P layers (3) are selectively formed in a top portion of an N⁻ body (2). A P⁻ layer (4a) is disposed in the top portion of the N⁻ body (2) so as to be spacewise complementary to the anode P layers (3). In the N⁻ body (2), P regions (5) are selectively formed below the P⁻ layer (4a). On the N⁻ body (2), an anode electrode (6) is disposed in contact with both the P⁻ layer (4a) and the anode P layers (3). A cathode electrode (7) is disposed under the N⁻ body (2) through a cathode layer (1). When the diode is reverse-biased, a depletion layer does not have a sharply curved configuration due to the P regions (5). Hence, concentration of electric field is avoided and a breakdown voltage would not deteriorate. During forward-bias state of the diode, injection of excessive holes from the anode P layers (3) into the N⁻ body (2) is prevented, thereby reducing a recovery current.

Abstract: The invention relates to a method and a device for exactly separating a main stack from an auxiliary stack in continuous deliveries of sheet-processing printing machines. The object on which the invention is based is to develop a solution which guarantees the exact separation of the main and auxiliary stacks and which prevents sheets from slipping back in the direction of the sheet ascent during the depositing operation. Furthermore, spearing actions caused by holding-up devices are to be avoided. This is achieved by means of a corresponding method and in that the carrier 22 and a crossbar 21 are articulated vertically movably, for example by means of cranks 14, on a crossmember 10 fastened to the sheet brake 9. Lower stops 12 and wedges 13 are arranged in the direction of the stack on the carrier 22, and mountings 17 for rear sheet holding-up devices 16 are provided on the side of the carrier 22 facing away from the stack. The sheet holding-up devices 16 pivot inwards in the stack region when a stack board 2 is pushed in. <IMAGE>

Abstract: A color sequential electronic camera includes an RGB light source in which the R and G sources are activated in combination to provide a luminance light beam, and the R and B sources separately to provide separate chrominance light beams. Image light reflected by a subject is captured by an image sensor, which generates a color sequential signal comprising a sequence of luminance and chrominance image components. By activating the light sources such that chrominance light beams alternate between luminance light beams, the chrominance image components are captured at a lower temporal rate than the luminance image components. Furthermore, by binning the sensor photosites together for the chrominance image, the chrominance components are captured at a lower spatial resolution than the luminance image components.
