    摘要： A stabilized storage phosphor is disclosed intended to be exposed to X-radiation and subsequently stimulated to emit light is disclosed. The storage phosphor is the product of firing a combination of species characterized by the relationship:MFX.sub.1-z I.sub.z.uM.sup.a X.sup.a :yA:eQ:tDwherein M is an alkaline earth; X is selected from the group consisting of Cl and Br; M.sup.a is an alkali; X.sup.a is a halide; A is selected from the rare earths Eu, Ce, Sm and Tb; Q is selected from among metal oxides; D is selected from elements 23 to 28 of the periodic table; z is from 1.times.10.sup.-4 to 1; u is from 0 to 1; y is from 1.times.10.sup.-4 to 0.1; e is from 0 to 1; and t is from 0 to 10.sup.-2. The storage phosphor is stabilized against decline of photostimulated luminescence intensities by the inclusion of a monocyclic compound having a molecular weight of less than 350, exhibiting both acid and base dissociation constants of less than 10.sup.-5 at 25.degree. C. and containing the following ring atoms: ##STR1## where N.sup.T represents a tertiary amine nitrogen atom, C.sup.1/2 represents primary or secondary carbon atom, O represents an oxy linkage, and Z represents a linking group providing two ring carbon atoms to complete a five-membered ring, An oxysulfur reducing can be employed in combination. The stabilized storage phosphor is useful in storage phosphor screens used to record imagewise exposures to X-radiation.

    摘要： A programmable logic circuit comprises a Programmable Array Logic (PAL) circuit in which individual product terms may be shared simultaneously by one or more of the circuit outputs. The product terms are selectively connected to the circuit outputs by programmable elements (such as a fusible link) to increase design flexibility. Isolating devices are provided in series with the programmable elements to allow for the simultaneous product term sharing.

    摘要： A process of preparing a high bromide tabular grain emulsion comprising a dispersion medium and silver halide grains including tabular grains having {111} major faces and an aspect ratio of at least 2, which contain greater than 50 mole percent bromide, based on silver, and which account for greater than 50 percent of total grain projected area, where such tabular grains have an average aspect ratio of at least 5, the process comprising (i) in a grain nucleation step creating in a dispersing medium tabular silver halide grain nuclei containing parallel twin planes and (ii) in a grain growth step subsequently growing the tabular grain nuclei into tabular grains in a silver halide reaction vessel by adding a silver ion source and a halide ion source to the reaction vessel and precipitating silver halide onto the tabular grain nuclei, wherein thiocyanate ion is introduced into the silver halide reaction vessel prior to the addition of at least the final 10 mole percent of the total silver added to the reaction vessel, and further wherein the introduced thiocyanate ion concentration is at most 0.4 mole %, based on the total silver added to the reaction vessel. Use of thiocyanate during grain precipitation result in increased aspect ratio without degrading morphological purity.

    摘要： A programmable logic circuit of the type known as a PAL (programmable array logic) incorporates a J-K register for each of the circuit outputs. The PAL includes a programmable array for generating products of selected input terms. The product terms available at the array outputs can be programmably allocated to either or both of the J and K inputs. The provision of isolating circuitry allows for simultaneous sharing of each product term by both the J and K inputs.
