摘要： Phosphor raw ingredients are homogeneously dispersed or dissolved in a liquid which is then spray dried to form particles having a predetermined particle size range, each particle containing substantially identical proportions of the raw materials. The particles are then passed through a fluidizing bed within a heated chamber, the chamber being maintained at a temperature high enough to react the particles to form phosphor matrices.

摘要： A photoflash lamp of the percussive type in which the primer thereof comprises a metal tube and a charge of fulminating material on a wire anvil supported therein. The wire anvil is an alloy of iron, nickel and chromium and it is chemically etched to promote better adhesion and reduce flaking of the coating of fulminating material thereon and it is flame or hot air passivated so that long term stability of the fulminating material is realized.

摘要： A support wire, having a bend near one end, is inserted into the coiled leg of a tungsten filament having a coiled body. The coiled leg is flexible enough to permit complete insertion of the support wire therein and to adapt the shape of the leg to that of the wire. The filament and wire assembly is then heat treated to modify the tungsten microstructure and stabilize the filament.

摘要： A multilayer magnetostatically coupled thin-film magnetic memory device comprising, in succession, a first magnetic film, a chromium-copper alloy conducting layer having a reasonably low resistivity, a smoothing layer, and a second magnetic film. Due to the presence of chromium in the chromium-copper alloy forming the conducting layer, when the second magnetic film is subsequently formed on the smoothing layer at an elevated temperature, the resulting grain growth and surface roughness of the chromium-copper alloy conducting layer are less severe than with other known metals having reasonably low resistivity values (e.g., copper, silver, gold, and aluminum) previously suggested for use as conducting layers in magnetostatically coupled thinfilm magnetic memory devices. Consequently, the effects of grain growth and surface roughness of the chromium-copper alloy conducting layer on the static magnetic properties of the second magnetic film are less severe than heretofore, and a smaller combined thickness of the conducting layer and smoothing layer is required to make the values of the static magnetic properties of the first and second magnetic films nearly equal. As a further result of the smaller combined thickness of the conducting and smoothing layers made possible by the use of chromium in the chromium-copper alloy, an improved magnetostatic coupling between the two magnetic films is obtained. An alternative multiplayer magnetostatically coupled thin-film magnetic memory device having no smoothing layer is also disclosed for use in less stringent applications where very close matching of the values of the static magnetic properties of the two magnetic films is not required.

摘要： Apparatus and method for measuring and computing velocity and acceleration of a pen point and the pen-paper contacts during writing of a signature and comparing derived data with reference data obtained from several prior signatures to determine whether the real time and reference signatures were made by the same person. The variations x(t) and y(t) of pen point coordinates with time and pen-paper contact intervals are obtained from a graphic tablet. Differentiator circuit means derive x and y velocity and acceleration components which are converted from analog to digital form for processing in a digital moment computer. Contact interval and end of signature computers receive pen point contact signals and compute the total time duration of the signature as well as the time duration of each of the first five pen-paper contact intervals normalized to the duration of the entire signature. The outputs of the moment, contact interval, and end of signature computers are sixteen components of a real time signature vector. A reference signature vector comprised of the mean values of sixteen similar components is predetermined from a plurality of prior true signatures, the deviation of each of those mean component values from the corresponding component value in a real time signature is compared with a variation limit value for that component to determine a correlation, and an authentication decision is made based on a minimum number of such correlations.

摘要： METHOD FOR FABRICATING MULTILAYER MAGNETOSTATICALLYCOUPLED THIN-FILM MAGNETIC MEMORY DEVICES. A PLURALITY OF LAYERS ARE DEPOSITED IN SUCCESSION ON A GLASS OR QUARTZ SUBSTRATE. THE LAYERS INCLUDE A FIRST PERMALLOY MAGNETIC FILM, A CHROMIUM BARRIER LAYER, A CHROMIUM-COPPER ALLOY SECOND PERMALLOY MAGNETIC FILM, A SILICON MONOXIDE PROTECTIVE LAYERS, A CHROMIUM MASKING LAYER, AND A PHOTOSENSITIVE RESISTANT MATERIAL MASKING LAYER. OPENINGS DELINEATING THE BOUNDARIES OF THE DESIRED MAGNETIC MEMORY DEVICES ARE THEN FORMED IN THE MASKING LAYER OF PHOTOSENSITIVE RESISTANT MATERIAL. SELECTIVE ETCHING MATERIALS ARE THEN USED, IN FOUR SUCCESSIVE ETCHING OPERATIONS, TO INITIALLY FORM AN OPENING IN THE CHROMIUM MASKING LAYER (FIRST ETCHING OPERATION), FOLLOWED BY OPENINGS IN THE SILICON MONOXIDE PROTECTIVE LAYER, THE SECOND PERMALLOY MAGNETIC FILM, THE SILICON MONOXIDE SMOOTHING LAYER, AND THE CHROMIUM-COPPER ALLOY CONDUCTING LAYER (SECOND ETCHING OPERATION), AN OPENING IN THE CHROMIUM BARRIER LAYER (THIRD ETCHING OPERATION), AND AN OPENING IN THE FIRST PERMALLOY MAGNETIC FILM (FOURTH ETCHING OPERATION).
