Abstract: A heating device, an image forming apparatus, and a liquid discharge apparatus. The heating device includes a heating roller having heat sources inside to heat a sheet. The heat sources include three or more first heat sources having a same distribution of thermal intensity and a second heat source having a distribution of thermal intensity different from the distribution of the thermal intensity of the first heat sources, and the second heat source is disposed inside a polygon whose vertices are the first heat sources when viewed from one end of the heating roller in a longitudinal direction of the heating roller. The image forming apparatus includes an image forming device to form an image on a sheet, and the heating device to heat the sheet. The liquid discharge apparatus includes a liquid discharge device to discharge liquid onto a sheet, and the heating device to heat the sheet.

Abstract: There is provided an information processing apparatus including a display unit, and a plurality of sensor elements, wherein the plurality of sensor elements are provided separate from the display unit, wherein the display unit is configured to switch display between a plurality of output screens based on a user input on the plurality of sensor elements, the plurality of output screens including output screens having different hierarchical levels and output screens having a same hierarchical level, and wherein the output screens having different hierarchical levels display information on the different hierarchical levels, and the switching display is controlled to switch display directly between the output screens having different hierarchical levels based on the user input.

Abstract: The present technology relates to an antenna and electronic equipment, whereby the antenna can be downsized. One or more standard coils including an opening part of a given size and one or more small coils including an opening part smaller in size than the opening part of the standard coil are connected electrically. A standard coil layer including the standard coil and a small coil layer including the small coil are stacked such that the opening part of the small coil lies within the opening part of the standard coil. A surface layer is the standard coil layer. The present technology can be applied to an antenna performing non-contact communication, and the like, for example.
