  • Patent number: 11289153
    Abstract: A memory device is disclosed, in which node contacts extend into a substrate, where they are come into electrical connection with active areas. This allows greater contact areas between the node contacts and the active areas and electrical connection of the node contacts with high ion concentration portions of the active areas. As a result, even when voids are formed in the node contacts, the node contacts can still possess desired connection performance. For node contacts allowed to contain voids, this enables them to be fabricated faster with lower difficulty, thus increasing manufacturing throughput of the memory device.

  • Patent number: 11155376
    Abstract: A cigarette filter rod boxing machine, including a cigarette filter rod holding mechanism and a cigarette filter rod pushing mechanism. The cigarette filter rod holding mechanism includes a lifting groove and a lifting power mechanism. The cigarette filter rod pushing mechanism includes a bottom plate, a middle push plate, a middle push vertical plate, an upper push plate, and an upper push plate limiting mechanism. The middle push vertical plate is vertically fixed on one side of the middle push plate, and the other side of the middle push vertical plate is precisely opposite to the other side of the U-shaped groove body. The first power mechanism used for controlling the middle push plate and the components on the middle push plate to advance to or return from the inside of the lifting groove is arranged between the bottom plate and the middle push plate.

  • Patent number: 10656169
    Abstract: A method of reducing carryover of liquids, such as reagent and/or samples, in analytical or immunoassay testing. The method includes providing an incubation member including a plurality of reaction vessels thereon, pre-assigning certain ones of the reaction vessels in the incubation member for only first test types or certain reagent types for all test lots; and pre-assigning other ones of a second subset of reaction vessels in the incubation member for only second test types for all test lots. By ensuring no mixing of potentially interfering test types or reagent types from test lot to test lot, sample and/or reagent carryover is mitigated. Testing apparatus adapted to carry out the methods are provided, as are other aspects.

  • Patent number: 9601647
    Abstract: The present invention includes upconversion materials such as lanthanide-sensitized oxides that are useful for converting low-energy photons into high-energy photons. Because silicon-based solar cells have an intrinsic optical band-gap of 1.1 eV, low-energy photons having a wavelength longer than 1100 nm, e.g., infrared photons, cannot be absorbed by the solar cell and used for photovoltaic energy conversion. Only those photons that have an energy equal to or greater than the solar cell's band gap, e.g., visible photons, can be absorbed and used for photovoltaic energy conversion. The oxides described herein transform photons having an energy less than the energy of a solar cell's band gap into photons having an energy equal to or greater than the energy of the band gap. When these oxides are incorporated into a solar cell, they provide more photons for photovoltaic energy conversion than otherwise would be available in their absence.

  • Publication number: 20100155698
    Abstract: The present invention relates generally to sub-microelectronic circuitry, and more particularly to nanometer-scale articles, including nanoscale wires which can be selectively doped at various locations and at various levels. In some cases, the articles may be single crystals. The nanoscale wires can be doped, for example, differentially along their length, or radially, and either in terms of identity of dopant, concentration of dopant, or both. This may be used to provide both n-type and p-type conductivity in a single item, or in different items in close proximity to each other, such as in a crossbar array. The fabrication and growth of such articles is described, and the arrangement of such articles to fabricate electronic, optoelectronic, or spintronic devices and components.
