  • Publication number: 20100177082
    Abstract: A gate driving circuit includes a shift register in which the stages are connected to each other one after another. An m-th stage includes a pull-up section outputting a high voltage of a first clock signal as a gate signal in response to a voltage of a first node, a pull-down section pulling down the gate signal to an off voltage in response to the first clock signal or the second clock signal, a driving section turning on and turning off the pull-up section and a holding section maintaining a voltage of the first node at the off voltage in response to the first clock signal, and a voltage maintenance section blocking a leakage current through the pull-up driving section and the holding section during an output interval of the gate signal to delay a voltage drop of the first node.

  • Publication number: 20020022746
    Abstract: Disclosed is the crystallization of Iopamidol using a mixture of an alcohol and water as a crystallization solvent. The ratios of water:Iopamidol from 1:10 to 1:1 (v/w) and alcohol:Iopamidol from 1:1 to 1:10 (v/w) allow Iopamidol to be crystallized to an anhydrous pure form with industrially valuable yields without producing monohydrates and pentahydrates.
