Granted: 1986-12-03
Abstract: The invention relates to a procedure and to equipment for generating a tomographic image of a three-dimensional object in a sectional plane (P). This procedure is of the type whereby the object is irradiated at various angles of incidence by beams converging on the sectional plane (P) and by detecting the radiation that has passed through the object for each angle of incidence in order to generate an electrical image signal. In the invention, the various image signals thus generated are processed by comparing their values at each point and by selecting for each image point that signal value which corresponds to the least radiation-attenuation; the selected values provide a synthesized signal representing the tomographic image. The procedure of the invention allows obtaining a tomographic image strictly free of the blurred traces due to the points located outside the sectional plane (P).

Abstract: A plastics sheet or laminate having the sheet as an outer layer has a surface of low friction and high gloss which is produced by extruding a layer of thermoplastic and pressing it while hot against the surface of a chill roller. The chill roller is highly polished and has minute randomly distributed superficial depressions therein of an average depth of about 5 microns, a depth standard deviation of less than 3 microns, an average frequency of about 3,000 per square centimeter, and an average area per depression of less than 1,000 square microns. The depressions are convex with rounded peripheries and are reproduced - as prominences - on the thermoplastic face material. The surface will have a coefficient of friction generally less than 1.0 with respect to itself, while nonetheless retaining a high gloss appearance. The sheet is useful as a protective outer layer of tubular containers e.g. toothpaste tubes.

Title: Adaptive misposition correcting method and apparatus for magnetic disk servo system

Filed: 1983-05-06
Granted: 1987-03-25
Abstract: A misposition correction system for correcting misposition errors due to spindle runout and other slowly varying errors in a servo positioning system of a magnetic disk storage device. The system includes means for dynamically measuring misposition error with respect to a data track centerline using an anti-aliasing analog filter, means for digitizing the measured analog signal and for removing selected harmonics of the fundamental-frequency of the resulting cyclic error signal, means for transforming the digitized error signal by a matched digital filter whose transfer function contains independently adjustable DC gain, fundamental-frequency gain, and phase lead components thereby to generate a misposition error correction signal that matches the electrical and mechanical response characteristics of the servo system. Further, the system include means to iteratively refine the correction signal by re-applying it to the servo controller when measuring misposition errors with respect to the data track centerline. The system stores separate misposition correction signals for each transducer on the disk so that one of several correction signals can be selected depending on which transducer in the device is selected. The system further includes means for generating a bias force correction signal to correct for non-linear position errors resulting from variations in bias forces acting on the transducer carriage over its range of radial displacement.
