Patent EP-0379012-A2 (EP)
Inventor: WICHMANN ARNOLD DR
IPC: H02K3/48
Filed: 1990-01-05
Abstract: The present invention relates to stators for large electrical machines, especially turbo generators, whose conductor windings consist partially of winding rods (4) laid in slots (3), as well as a corresponding production process taking into account the methods of total impregnation of the completely assembled arrangement with curable artificial resin. In stators of large electrical machines according to the invention, which are subjected to complete impregnation with artificial resin, the extensive applications according to the prior art for fixing the position of the winding rods (4) in the slots (3) are not necessary. In the case of installation of the winding rods (4), fixing of the position is necessary only to the extent that position changes of the winding rods (4) in the further course of the production process must be prevented. The closure of the slots (3) and the fixing of the winding rods (4) take place using simple, slightly sprung slot closing strips (7) which are fitted into recesses (8) of the slots (3) in the region of the slot openings (9). After impregnation with the resin, followed by curing, the winding rods (4) are fixed into the slots (3) essentially only by the cured impregnated resin. This permits the simple and economical production of particularly robust stators of high electrical and mechanical quality. <IMAGE>

Abstract: A method and system for accurately and objectively evaluating the numismatic quality of a test coin and/or for fingerprinting the test coin for purposes of identification is disclosed. Important to both the grading and fingerprinting aspects of the invention is the exact, numerical evaluation of any detracting marks on each side of the coin. In addition, systems and methods for illuminating an object surface with light at varying angles of incidence and for optically evaluating the object surface for features and defects, etc. are disclosed. In a specific implementation of these systems and methods, the target object comprises a coin and the illumination and evaluation techniques are used to accurately objectively evaluate the numismatic quality of the coin and/or identify the coin. Important to the illumination and evaluation techniques is the ability to apply a uniform confined beam of light to the surface of the target object to be imaged.

Abstract: A bar code reader reads a bar code (7) by scanning a laser beam on a screen (6) on which the bar code (7) is displayed. The bar code reader has a beam scanning device (15) for scanning the laser beam irradiated from a laser oscillator (2). The beam scanning device (15) has a polygon mirror (4) which is rotated and driven around an axis (41). The polygon mirror (4) forms at least two kinds of flat reflecting surfaces (4a), (4b) for respectively scanning the laser beam along with the rotation of the polygon mirror (4). Scanning angles (α), (β) by the reflecting surfaces (4a) , (4b) are twice as large as opposite angles (ϑ1), (ϑ2) to which the reflecting surfaces (4a), (4b) correspond respectively. The laser beam is scanned at two or more kinds of scanning angles, that is, scanning angles (α), (β) which are respectively adapted to the long and short bar codes (7). Therefore, the bar code (7) can be accurately read irrespective of a length thereof.

Abstract: A fabrication method for applying conductive traces (50) to a substrate (12) is described. The method uses an ink which is applied to a substrate (12) by an ink jet delivery system (14). The ink includes an adhesive in combination with other additives, including one or more solvents. The ink is delivered by the ink jet system (14) in a selected pattern (20), followed by placement on the pattern (20) of a flexible film sheet (30) having a layer of metal (40) thereon. The film (30) is urged downward onto the pattern (20) with the application of heat and pressure. This causes adhesion of the layer of metal (40) to the adhesive in the ink. The film (30) is then removed, leaving a coating of metal on the pattern (20), thereby producing conductive trace patterns (50) in a rapid and efficient manner.

Abstract: According to a method and apparatus for coding a moving image signal, a change between a current frame and a previous frame is detected in units of blocks obtained by dividing a frame constituted by an input moving image signal into a plurality of pixels. A first valid block map is formed in units of frames by determining valid and invalid blocks on the basis of the detected changes. A first weighting operation of the formed first valid block map is performed. A second weighting operation of a fourth valid block map of the previous frame is performed. A weighted second valid block map is obtained by adding/synthesizing the first and fourth valid block maps respectively subjected to the first and second weighting operations. A third valid block map is obtained by performing predetermined segmentation of the second valid block map. A fourth valid block map is obtained by determining validity of an isolated invalid block in the third valid block map by referring to neighboring blocks. A valid block region of the fourth valid block map is coded.
