  • Patent number: 9280120
    Abstract: A decolorizing apparatus includes first and second heating units, first and second heat source units, and a controller. The first and second heating units decolorize an image using decolorable colorants which are decolorized if heated. The first heating unit heats one surface of a sheet. The second heating unit heats a remaining surface which is opposite to the one surface of the sheet heated by the first heating unit. The first heat source unit heats the first heating unit. The second heat source unit heats the second heating unit. The controller includes a first mode and a second mode. In the first mode, the controller performs a decolorizing process on both the surfaces of the sheet by heating the first and second heating units using the first and second heat source units.

    Abstract: An apparatus for processing messages input from a plurality of clients. The apparatus includes an acquisition unit configured to obtain a first message input from a first client, a second message input from a second client, and a user selection input from the second client. The user selection is of a first portion of the first message and indicates that the second message is a comment on the first portion of the first message. The apparatus also includes a control unit in communication with the acquisition unit. The control unit is configured to perform a first control action in response to the acquisition unit obtaining the first message, the second message, and the user selection. The first control action results in the first message, the second message, and a first link connecting the first portion of the first message and the second message being displayed on the plurality of clients.

  • Publication number: 20160004676
    Abstract: A data processing unit extracts identification information which identifies contents of displayed dynamic content from a Web page displayed on a display device and holds the identification information in a content information holding unit. A display control unit checks, in relation to dynamic content contained in a Web page to be newly displayed on the display device, whether or not identification information which identifies contents of the dynamic content at a specific time point is held, if the Web page is the same Web page as a currently displayed Web page or is a Web page displayed previously, and displays the dynamic content of the newly displayed Web page based on the identification information about the dynamic content contained in the newly displayed Web page if the identification information is held.

    Abstract: At least, a temperature of the surface of a heating roller 13 in a region through which paper of small width passes, and a temperature of the surface of a heating roller 13 in a region through which paper of small width does not pass where paper of large width is carried are detected. Warming up operation is continued, and when a temperature of the surface of a heating roller 13 in the either region reaches a temperature capable of fixing, a ready display is lighted. Thereafter, the surface of the heating roller 13 not having reached a temperature capable of fixing is heated by forcibly lighting a heater lamp till the fixed conditions are satisfied, and at the time of the forcible lighting operation, the surface of the heating roller 13 in a region having reached a temperature capable of fixing is not heated.
