  • Publication number: 20100265269
    Abstract: A portable terminal includes: a display unit configured to display data on a screen; a rotation detecting unit configured to detect rotation of the portable terminal; a touch detecting unit configured to detect touch of the screen of the display unit; and a display control unit configured to, when rotation is detected by the rotation detecting unit and touch is detected by the touch detecting unit, revolve display content displayed on the screen in conformity with the rotation of the portable terminal. According to the portable terminal, by allowing the user to specify an axis of rotation when changing the screen display direction, it is possible to prevent a change that is against the intention of the user, and also to change the display direction in a state in which a portion that the user wants to display among the display contents remains displayed.

  • Publication number: 20060251819
    Abstract: The copolymer latex for non-contact coating of the present invention is obtained by emulsion polymerization of a monomer containing from 23 to 58% by mass of an aliphatic conjugated diene monomer, from 0.1 to 7% by mass of an ethylenic unsaturated carboxylic acid monomer, from 5 to 40% by mass of a vinyl cyanide compound, and from 0 to 71.9% by mass of other monomer capable of being copolymerized with the other monomers (provided that the total amount of the monomers is 100% by mass), and polymer particles contained in the latex have an average particle diameter of from 50 to 150 nm. A coating composition for paper containing the latex, a pigment and the like is suitable for a non-contact coating method, such as a curtain coater and a spray, to obtain coated paper excellent in surface strength, printing gloss and the like with good runnability.
