    摘要: An image display is provided with a display area including pixels, each including illuminating means. A control circuit turns the illuminating means of the pixels on and off. A first terminal of a capacitor is connected to an input terminal of the control circuit. An image signal voltage generation circuit generates image signal voltages and a pixel drive voltage generation circuit generates pixel drive voltages for the pixels. A connector is provided for connecting either one of the image signal voltages or the pixel drive voltages to a second terminal of the capacitor. As such, an amount of drive current for the pixels is controlled in accordance with both the pixel drive voltage and the image signal voltage.

    摘要: Disclosed is a method for synthesizing t-butyl (meth)acrylate at low cost. Specifically, disclosed is a method for synthesizing a carboxylic acid ester by performing an addition reaction between isobutylene and (meth)acrylic acid in the presence of an acidic catalyst. This method includes the steps of: (A) performing a dehydration decomposition reaction of t-butyl alcohol in the presence of a first acidic catalyst; (B) obtaining crude isobutylene gas by separating at least water from a produced gas obtained in the step A; (C) absorbing the crude isobutylene gas in an absorption solvent containing (meth)acrylic acid; and (D) producing t-butyl (meth)acrylate by performing the addition reaction by bringing the absorption solvent which has absorbed the crude isobutylene gas into contact with a second acidic catalyst.
