  • Patent number: 7935765
    Abstract: The present invention is a composition useful as an impact modifier for polyamide compositions. In one embodiment, impact modifiers of the present invention are ethylene maleic anhydride copolymers having at least 3% maleic anhydride functionality. Compositions comprising copolymers of ethylene and maleic anhydride or its functional equivalents and ethylene copolymers with polar comonomers are disclosed. The compositions provide miscible blends and exhibit improved properties, such as increased temperature resistance and mechanical strength, compared to pure ethylene copolymers with polar comonomers.

  • Patent number: 7936527
    Abstract: An auto focus lens module with a piezoelectric actuator having a piezoelectric actuator, a tangent thrust element, a sliding fixture, a metal member, a guiding fixture, and a lens barrel is revealed. By a thrust in the tangent direction generated from the tangent thrust element toward the outer edge of the lens barrel, a friction is generated between the lens barrel and the piezoelectric actuator. When the piezoelectric actuator is applied with a voltage, the lens barrel driven by the piezoelectric actuator moves along an optical axis for focusing with the auxiliary of the guiding fixture. Due to fewer elements, light weight and compact volume, the design is applied to miniature auto focus lens modules so as to achieve effects of fast movement, stable focusing and reduced tilting.

  • Publication number: 20110094505
    Abstract: The present invention relates to an enhanced process for sugar production through the acid hydrolysis of cellulosic and lignocellulosic materials characterized by the treatment of these materials in three steps. In the first step, it is made a digestion of the lignocellulosic material using a solvent capable of partially dissolving the lignin, which constitutes part of the lignocellulosic material. In the second step, the cellulosic material resulting from the treatment with the solvent is subjected to an acid treatment in such conditions that mainly hemicellulose is hydrolyzed to form a sugar solution rich with pentose monomers and oligomers. In the third step, the cellulosic material from the second step is subjected to an acid treatment in such conditions that the major part of the cellulose is hydrolyzed to form a sugar solution rich with hexose monomers and oligomers.
