Abstract: A perpendicular magnetic recording data storage system combines a perpendicular medium that has a thin low-magnetic-permeability or “soft” underlayer (SUL) with a recording head that has a trailing shield (TS) with a thick throat height, i.e., a thickness in a direction orthogonal to the recording layer of the medium. The SUL is thin enough and has a low enough magnetic permeability to become saturated in a region beneath the trailing gap of the head during writing, but the throat height of the TS is thick enough to prevent the TS from becoming magnetically saturated during writing. The magnetic saturation of the SUL during writing changes the magnetic reluctance such that more of the magnetic flux going through the SUL changes direction (“field undershoot”) and goes to the TS. If the permeability of the SUL is so low (e.g.

Abstract: A polishing wheel including a lower polishing surface and defining a different color from a secondary portion of the polishing wheel, so as to indicate wear of the polishing surface. The polishing surface includes a plurality of main radial flutes extending from a central passage to an outer edge. A reduced profile for the main radial flutes is provided adjacent to the outer edge. A plurality of secondary radial flutes is provided extending from the outer edge, but not in communication with either the central passage or the main radial flutes.

Abstract: A method for estimating the average intergranular exchange field using measurements of major and minor hysteresis loops. The method also facilitates deshearing hysteresis loops for analysis purposes in perpendicular media. This estimation technique is especially important for modern perpendicular media because exchange plays a critical role and process control can be difficult.

Abstract: A windowed postcard mailer intermediate is provided so that the mailer can be processed by simplex printing, printing only on a single side. The windowed mailer intermediate of the present invention is printed with customer interaction indicia which may include a negotiable instrument such as check, coupon or the like or alternatively, the indicia may include response or interest surveys, membership cards or similar mailings intended to extract some sort of indication of interest by the recipient. The address is printed on the face of the mailer intermediate and upon folding of the intermediate about a fold line, the address is visible through a window cutout.

Abstract: A resistor structure is disclosed that is constructed out of two layers of polysilicon. The intrinsic device is made using the top layer which is either a dedicated deposition, or formed as part of an existing process step such as a base epi growth in a BiCMOS flow. This poly layer can be made with a relatively high (greater than 2000 ohms per square) sheet resistance by appropriate scaling of the implant dose or by insitu doping methods. In this invention this layer is arranged to be about 1000 A or less thick. Such a resistor form with this thickness has been shown to demonstrate a better standard deviation of resistance compared to resistors made with a thicker layer. Additionally, practical resistors made in elongated forms demonstrate better standard deviations of resistance when five bends were incorporated into the form. The resistor ends are formed by the addition of a bottom poly layer in a self aligned manner with a deposition that may already be part of the process sequence.

Abstract: A focus detecting system for detecting focus state of an image forming optical system relative to an object, includes a beam splitter assembly for forming at least three coplanar two-dimensional images of a scene, each image having a different focus setting. An area array image sensor senses the images at the image forming plane. Signal processing electronics determine the sharpness of the three images and calculates an optimum focus setting for the optical system by deterring the variances of the three images and calculating a position of maximum variance corresponding to a best focus setting of the optical system.

Abstract: A method and apparatus for positioning, aligning and orienting fibers in flowing fluids, to permit fibers such as wood pulp fibers to be accurately imaged and rapidly measured with little operator involvement, utilizing a plugging resistant and fouling resistant sheath flow cell, is described. An embodiment is disclosed which simultaneously determines the distributions of shape (curl) and length of samples of wood pulp fibers. Fibers are transported in a dilute water suspension through a sheath flow cell that orients fibers normal to an imaging system that includes a two-dimensional CCD video camera. Images of fibers are analyzed rapidly by a processor, which calculates the shape and length of individual fibers. The data are displayed on a cathode ray tube screen while a pulp sample is being analyzed, and are stored in processor memory for further analysis.
