  • Publication number: 20190244998
    Abstract: An imaging device includes an image sensor chip. The image sensor chip includes a photosensitive surface and, opposite to the photosensitive surface, a bottom surface. The photosensitive surface includes a sensitive region, a peripheral transition region surrounding the photosensitive region, and an input/output wiring region surrounding the peripheral transition region. At least one input/output wiring pad is disposed in the input/output wiring region. The imaging device also includes a selective filter cover, disposed above the photosensitive region; and a retaining wall, disposed in the peripheral transition region and bonded to the selective filter cover. The retaining wall and the selective filter cover together form a closed cavity above the photosensitive region. The imaging device further includes a plurality of outgoing wires. A terminal of each outgoing wire is connected to an input/output wiring pad, and another terminal of the outgoing wire extends out from the image sensor chip.

  • Publication number: 20180305530
    Abstract: This disclosure relates to a continuous solution three reactor polymerization process. Process solvent, ethylene, optional comonomers, optional hydrogen and a single site catalyst system are injected into a first and second reactor configured in parallel to one another. A third reactor receives effluent from the first reactor, the second reactor, or a combination of the first and second reactors. Fresh monomer is feed to the third reactor for further polymerization and to give a final polyethylene product.

  • Publication number: 20180305532
    Abstract: A continuous solution polymerization process is disclosed wherein at least two homogeneous catalyst formulations are employed. A first homogeneous catalyst formulation is employed in a first reactor to produce a first ethylene interpolymer and a second homogeneous catalyst formulation is employed in a second reactor to produce a second ethylene interpolymer. Optionally a third ethylene interpolymer is formed in a third reactor. The resulting ethylene interpolymer products possess desirable properties in a variety of end use applications, for example in film applications. A means for increasing the molecular weight of the first ethylene interpolymer is disclosed and/or a means for increasing the temperature of the first reactor, relative to the third homogeneous catalyst formulation. A means for reducing the (?-olefin/ethylene) weight ratio in the first reactor is disclosed and/or reducing the density of the first ethylene interpolymer, relative to the third homogeneous catalyst formulation.

  • Patent number: 10093780
    Abstract: Shrink film having a desirable balance of properties is manufactured from a polyethylene blend composition having a fractional melt index and a molecular weight distribution of from about 2.5 to about 7. The blend composition comprises a first blend component that is made with a single site catalyst and has a molecular weight of greater than about 140,000 and a first density, d1. The blend composition also contains a second blend component having a lower molecular weight and a second density, d2, that is greater than the density of d1 in an amount of from about 0.018 to about 0.032 g/cc. The films of this disclosure may be used, for example, as an overwrap or pallet wrap to protect goods during shipping and in food packaging applications (such as shrink wrap for frozen poultry).
