  • Patent number: 10914006
    Abstract: A nanoparticle continuous-coating device based on spatial atomic layer deposition. A first-stage pipeline unit, a second-stage pipeline unit, a third-stage pipeline unit and a fourth-stage pipeline unit which are connected sequentially. The first-stage pipeline unit is used for providing a first precursor and enabling the first precursor to be adsorbed on surfaces of nanoparticles. The third-stage pipeline unit is used for providing a second precursor and enabling the second precursor to react with the first precursor on the surfaces of the nanoparticles, so that a monomolecular thin film layer is generated on the surfaces of the nanoparticles. The second-stage and fourth-stage pipeline units are used for cleaning the nanoparticles and discharging the redundant first precursor, the redundant second precursor or reaction by-products.

  • Publication number: 20180081192
    Abstract: The present invention creates a new way of arranging harsh marks on a reticle that is to have the 2/10th and the 4/10th hash mark placed either above or below the horizontal base sighting line (See FIG. 2. Line 26) or on the left or right side of the vertical sighting base line (See FIG. 2. Line 27) at any unit of measurement of a segment and have the 6/10th and the 8/10th hash mark placed at the opposite side of the horizontal base sighting line (See FIG. 2. Line 26) and the vertical sighting lines (See FIG. 2. Line 27) compared with the 2/10th and the 4/10th marks. This new way of placing hash marks at every 2/10th of the unit of measurement allows a user to quickly identify and discern which numerical value a hash mark represents on the horizontal base sighting line and vertical sighting line without physically counting the numerical value of a hash mark in a linear way.
