Abstract: A niobium-titanium-based oxide includes niobium-titanium-based oxide particles, wherein an Si2p peak area and an Nb3d peak area, as measured by X-ray photoelectron spectroscopy for the niobium-titanium-based oxide particles, satisfy a ratio A of 0.40?A?1.0, provided that the ratio A is the Si2p peak area/the Nb3d peak area.

Abstract: In a display system according to the present disclosure, a server device includes an authentication processor that authenticates a user for use of a file, based on authentication information of the user input at a user terminal and an access information generator that generates first access information for accessing the file if the user is authenticated by the authentication processor for use of the file, and a display device includes a file acquirer that acquires the file from the server device, based on the first access information generated by the access information generator, and a display processor that displays the file acquired by the file acquirer, on the display.

Abstract: An electronic blackboard apparatus includes a display device and a control device. The display device includes a control unit having faster activation speed than the control device, and an input switching unit switching control of display of the display device between the control unit and the control device. The control unit controls the display of display device. Further, the control unit detects activation of the control device. When activation of the control device is detected by the control unit, the input switching unit switches control of display of display device to control by the control device. The control device controls display of the display device by an electronic blackboard application software having larger number of functions for controlling the display than the control unit.

Abstract: An image display device includes a display unit that displays images in page units and a memory which stores data, and flashes an import button displayed on the display unit upon receipt of image data, and in response to operation of the import button by a user, stores received image data on a virtual page in the memory corresponding to a blank page that is on display, stores the received image data on a virtual page in the memory corresponding to a blank page following the page on display, or stores the received image data on a virtual page in the memory secured as a new page following the page on display, after which the image display device displays the image data stored on the virtual page as an image on the display unit. This makes it possible to display the received image at a time specified by the user.

Abstract: A system for inputting label related information and for printing and applying labels to articles or the like is constituted of a self-contained label printer unit, a separate self-contained data inputting unit and a self-contained power supply unit which houses the relatively heavy power supply and other circuits which do not require to be contained in either the data input unit or in the label printer. The power supply unit requires no holding by hand and is thus suitable for being stored in the operator's pocket or attached or strapped to the operator's waist. Initially, only the data unit needs to be handled by hand for entering label related information. Thereafter, the label printer unit is manipulated by hand to cause labels to be printed and to be applied to articles. The data input unit may be connected to the power supply directly as by cable or the like or, to obtain greater mobility and ease of use, wirelessly by means involving transfer of information by light or sonic waves.
