  • Publication number: 20160379300
    Abstract: A prediction device according to the present application includes an acquisition unit and a prediction unit. The acquisition unit acquires information on a current price at which a target product is bid at an auction. The prediction unit predicts a price difference between the current price and a future price at which the target product is assumed to be bid after bidding at the current price based on the information on the current price acquired by the acquisition unit and a bid history at the auction. For example, the prediction unit predicts a price difference between the current price and the future price at which the target product is assumed to be bid immediately after bidding at the current price.

  • Publication number: 20060289191
    Abstract: The invention provides a shield case of a disk device for shielding electromagnetic noises irradiated from a circuit board of a disk device, which can be downsized. A shield case 15 is divided into two parts, a first shield case 15A and a second shield case 15B. While enclosing the whole body of the circuit board 6 therein, the shield case 15 is fixed horizontally to the upper surface of the frame 7. The electromagnetic noises irradiated from the circuit board 6 are shielded by the shield case 15. By covering the circuit board 6 with the shield case 15 for shielding electromagnetic noises, the shield case 15 can be downsized as a compact component, and thus a disk device 1 to which the shield case 15 is assembled can also be downsized.
