Title: Thermistor and method of making the same
Inventor: BURKE FRANCIS M
IPC: H01C17/02
Filed: 1990-06-19
Abstract: A method of making a thermistor comprising the steps of making a layer of thermistor ceramic material comprised substantially of Mn2O3, NiO, Co3O4, Al2O3, CuO, or Fe2O3, having upper and lower surfaces.  A first dielectric material comprised of low K Al2O3 or the like is placed on the upper and lower surfaces of the layer, and then is cut into a plurality of elongated strips.  The layer is created by blading a slurry of the ceramic material to create a plurality of uncured sheets; placing the sheets in superimposed position, and then making the monolithic layers from the sheets by applying heat and pressure thereto, and then firing the monolithic layer with heat of increased magnitude.  The strips are encapsulated in an envelope of the dielectric material, and terminal connections comprised of silver, Ni, Sn and Pb are imposed thereon.  A therm-istor chip or strip comprising an elongated ceramic thermistor body with an outside surface and opposite ends.  A dielectric envelope encapsulates the outer surface of the body for the ends, and conductive terminal caps are formed on the end of the body.  The thermistor is comprised of the materials outlined in the method of making the same.

Title: Multilayered leadframe with interdigitated leads
Inventor: JONES KENNETH L II
IPC: H01L23/50
Filed: 1990-10-05
Abstract: MULTILAYERED LEADFRAME WITH INTERDIGITATED LEADS    ABSTRACT OF THE DISCLOSURE        A   leadframe   for   accomplishing   electrical connection  to an electronic device is formed of two or more  segments,  each  having  a set of leads extending therefrom.

Title: Data compression system and method
Inventor: ALVES JAMES F
IPC: H04N7/30
Filed: 1991-03-26
Abstract: IMPROVED DATA COMPRESSION SYSTEM AND METHOD                        ABSTRACT Image data compression is implemented by partitioning an image into rela-tively small blocks of pixels, matching each block to an orthogonal icon, and extract-ing attributes associated with the icon. A table of these orthogonal icons and at-tributes represents a data compressed image. Each block is processed separately from all other blocks. Orthogonal processing is used to preserve orthogonal features while attenuating non-orthogonal features. An optimum set of orthogonal icons and an optimum set of attributes for each icon further improves data compression and fi-delity. The optimal set of orthogonal icons includes a flat icon, an edge icon, a rib-bon icon, a corner icon, and a spot icon. An optimal set of attributes includes aver-age intensities, intensity transition position and separation, and angle of the principal axes.
