  • Patent number: 10811256
    Abstract: Methods for etching a carbon-containing feature are provided. The methods may include: providing a substrate having a carbon-containing feature formed thereon in a reaction space; supplying helium gas and an oxidizing to the reaction space; generating a plasma within the reaction space from a gas mixture comprising helium gas and the oxidizing gas; and anisotropically etching the carbon-containing feature utilizing the plasma to cause lateral etching of the carbon-containing feature.

  • Publication number: 20200222290
    Abstract: The problem to be solved by the present invention is to provide a water-in-oil-type solid cosmetic which contains an ultraviolet ray absorber, can be solidified with a wax, rarely undergoes a sweating phenomenon, and has excellent sensation upon use. A water-in-oil-type solid cosmetic is capable of being solidified with a wax, the solid cosmetic contains a continuous-phase oil that contains an organic modified silicone and can form a continuous oily phase, a wax that is compatible with the continuous-phase oil, an ultraviolet ray absorber and an aqueous phase, wherein oily phase droplets each contain the ultraviolet ray absorber and aqueous phase droplets are dispersed separately in the continuous phase oil having the wax dissolved therein.

  • Patent number: 10712540
    Abstract: An imaging lens includes a first lens; a second lens; a third lens; a fourth lens; a fifth lens; a sixth lens; and a seventh lens, arranged in this order from an object side to an image plane side. The imaging lens has a total of seven lenses. The first to seventh lenses are arranged respectively with a space in between. The second lens is formed in a meniscus shape near an optical axis. The third lens is formed in a meniscus shape so that a surface on the object side is convex near an optical axis. The sixth lens is formed in a meniscus shape near an optical axis. The seventh lens is formed in a shape so that a surface on the image plane side has at least one inflexion point. The first lens and the second lens have specific Abbe's numbers.

  • Patent number: 10658181
    Abstract: A method of spacer-defined direct patterning in semiconductor fabrication includes: providing a photoresist structure having a target width of lines; trimming the photoresist structures such that a width of each trimmed photoresist structure is smaller than the target width; depositing an oxide film on the template, thereby entirely covering with the oxide film an exposed top surface of the template and the trimmed photoresist structures; etching the oxide film-covered template to remove an unwanted portion of the oxide film without removing the trimmed photoresist structures so as to form vertical spacers isolated from each other, each spacer substantially maintaining the target width and being constituted by the trimmed photoresist structures and a vertical portion of the oxide film covering sidewalls of the trimmed photoresist structures; and etching the spacer-formed template to transfer a pattern constituted by the spacers to the template.

  • Patent number: 10636976
    Abstract: A novel compound in which a delayed fluorescence component due to TTA accounts for a high proportion of emissive components is provided. The organic compound includes an anthracene skeleton, an arylene group, and a substituted or unsubstituted heterocyclic group including a carbazole skeleton. The anthracene skeleton and the substituted or unsubstituted heterocyclic group including the carbazole skeleton are bonded to each other through the arylene group. The anthracene skeleton includes an aryl group at the 2-position or the 3-position.

  • Publication number: 20200125005
    Abstract: The developer container includes a rotator that is rotated in the container body, a sequence of gears disposed outside the developer container that transmits a torque to the rotator, and a container guiding portion that fits with a main body side guiding portion and guides the developer container in a direction in which the developer container is attached to a mounting portion of an image forming device main body. A first gear included in the sequence of the gears is movable between an operating position where the first gear engages with a second gear and a retracted position where the first gear is retracted. On a surface on which the container guiding portion is disposed, a part of the container guiding portion is disposed within a projected area of the first gear being disposed at the operating position.
