  • Publication number: 20170037178
    Abstract: A block copolymer useful in electron beam and extreme ultraviolet photolithography includes a first block with units derived from a base-solubility-enhancing monomer and an out-of-band absorbing monomer, and a second block having a low surface energy. Repeat units derived from the out-of-ban absorbing monomer allow the copolymer to absorb significantly in the wavelength range 150 to 400 nanometers. When incorporated into a photoresist composition with a photoresist random polymer, the block copolymer self-segregates to form a top layer that effectively screens out-of-band radiation.

  • Publication number: 20160017615
    Abstract: Methods, systems and apparatuses for providing high electrical resistance for an upper control assembly (including control handles) of an aerial lift are provided through an isolation member that is integral to the upper control assembly and interposed between fluid lines in the control assembly and a set of fluid conduits that extend from the control assembly towards other portions of the aerial lift. The isolation member is a dielectric element that comprises a manifold that is made of material that is substantially electrically non-conductive, and that has a plurality of through-holes or hoses configured to allow hydraulic fluid to flow through the isolation member into and out of the fluid lines and conduits. These methods, systems and apparatuses are preferably used in upper control assemblies of aerial platforms that can carry one or more operators in order to prevent such operators from electrocution when controlling the lift.

  • Publication number: 20150298336
    Abstract: A sheet processing apparatus and methods of utilizing the same. The sheet processing apparatus includes a punch mechanism disposed along a media path at a punch point at which a hole is to be punched through a punch location on a media sheet advancing along the media path. The punch mechanism includes a rotatable punch arm having a punch head, and a punch motor for rotating the punch arm. As the punch location on the advancing media sheet approaches the punch point, speed of the punch motor is controlled to adjust a rotational speed of the punch arm based on feedback signals associated with each of the punch motor and a media path motor used to advance the media sheet such that the punch head arrives at the punch point at substantially the same time as when the punch location on the media sheet arrives at the punch point.
