  • Patent number: 6552409
    Abstract: A memory array and some addressing circuitry therefor are formed by creating circuit elements at the crossing-points of two layers of electrode conductors that are separated by a layer of a semiconductor material. The circuit elements formed at the crossing-points function as data storage devices in the memory array, and function as connections for a permuted addressing scheme for addressing the elements in the array. In order to construct the addressing circuitry, the electrode conductors are fabricated with a controlled geometry at selected crossing-points such that selected circuit elements have increased or decreased cross-sectional area. By applying a programming electrical signal to the electrodes, the electrical characteristics (e.g. resistance) of selected circuit elements can be changed according to the controlled electrode geometry.

  • Publication number: 20020191434
    Abstract: A memory circuit includes a cross-point memory array having first and second sets of transverse electrodes with respective memory elements formed at the crossing-points of the first and second set electrodes. Each of the memory elements is formed to include, in at least one of its binary states, a diode element. The memory circuit also includes an addressing circuit coupled to the memory array. The addressing circuit has a first set of address lines with first diode connections between the first set address lines and the first set memory array electrodes, with the first diode connections coupling each memory array electrode in the first set to a respective unique subset of the first set address lines.

  • Publication number: 20020184459
    Abstract: A data storage system that is adapted for storing image data in digital cameras comprises a temporary data storage circuit coupled, in use, to receive image data from the camera, and a permanent data storage circuit coupled, in use, to receive image data from the temporary data storage circuit. A control circuit is coupled to the temporary data storage circuit and the permanent data storage circuit to effect transfer of image data from the temporary data storage circuit to the permanent data storage circuit upon occurrence of a predetermined event. The permanent data storage circuit may be in the form of a write-once non-volatile memory module, which is replaceable in the storage system. The temporary data storage circuit can be a RAM or Flash memory that temporarily stores a image data from the camera when a picture is taken. Then, the user may review the picture before it is permanently stored upon the occurrence of the predetermined event.

  • Patent number: 5855790
    Abstract: Magnetic particles which comprise a core of a magnetic material surrounded by a mixture of a fibrous material and a solid binding agent. The particles may be embedded in a polymer resin which incorporates sites, which are selective for particular ions, to form composite magnetic resin particles. The composite magnetic resin particles may be used for the removal of pollutant ions from an aqueous solution in which they are contained.

  • Patent number: 5852786
    Abstract: A process for the decontamination of radioactive materials which process comprises the steps of: i) contacting the material to be decontaminated with a dilute carbonate containing solution in the presence of ion exchange particles which either contains or have a chelating function bond to them; and ii) separating the ion exchange particles from the dilute carbonate containing solution. The radioactive materials which are treated may be natural materials, such as soil, or man-made materials such as concrete or steel, which have been subjected to contamination.

  • Patent number: 5805654
    Abstract: A method for operating the LOMI decontamination process in a regenerative manner. The method incorporates an initial injection of a dilute LOMI solution (vanadous formate, picolinic acid and sodium hydroxide) into a decontamination circuit followed by operation of a small cluster of cation exchange columns during the decontamination process. The cation exchange resin is used to remove metals in the same manner as in prior decontamination processes but operation of the cation exchange resin is continued to allow picolinic acid initially bound to the cation exchange resin to be released and recycled to the LOMI solution. Operation of the cation exchange columns ceases after the picolinic acid has been released but before the metals (e.g. sodium, iron and vanadium) are released back to the LOMI solution. The cluster of cation exchange columns are operated according to a sequence wherein one column is releasing picolinic acid while another is binding picolinic acid.

  • Patent number: 5724668
    Abstract: A process for removing undesirable material such as a radioactive contaminant from an underlying material. A solution containing fluoroboric acid and a material which affects oxidation potential (Eh) is contacted with the undesirable material to cause its removal. The material is removed from the fluoroboric acid solution by contacting the solution with a cation exchange resin and fluoroboric acid is regenerated in situ for continuous removal of undesirable material.

  • Patent number: 5225037
    Abstract: A flexible polyimide film is used to support an array of precisely located contact bumps which are used to probe die on a wafer of semiconductor circuits, or an unmounted integrated circuit die, several integrated circuits, or hybrid devices. By utilizing a standard I/O contact pattern for the flexible film and fabricating the membrane assembly of interconnects on an aluminum substrate, it is possible to produce a more reliable probe card, while reducing the fabrication time and costs for the probe card. The polyimide film must be selected to have a CTE of 3 to 5, which is only about 1/5 to 1/7 as great as the CTE of the aluminum substrate on which the film is formed. This produces a critical degree of compressive stress in the polyimide film, and a resulting "bow" of the film when the central area of the aluminum is etched away.

  • Patent number: 5205437
    Abstract: A single article dispensing apparatus adapted for newspaper vending captures a bundle of newspapers between opposing support plates with one movable plate being spring biased toward the stationary plate. Newspaper engaging pins extend beyond the stationary support plate and into the space between the opposing support plates to engage the back edge of a newspaper of the bundle. Upon deposit of the necessary coins and pulling of a dispensing handle, the newspaper engaging pins slide the newspaper from the bundle and out through an output door of the vending machine. When all newspapers in the bundle are dispensed and the support plates come to direct face-to-face opposition, a last copy of the newspaper held behind a display window is automatically dispensed upon the next actuation of the dispensing handle. The vending machine restricts access to the inventory of newspapers and allows a purchaser but one copy of the newspaper for payment of one copy.
