Abstract: One aspect of the present invention relates to a recovery method of 226Ra, and the recovery method of 226Ra includes a step (A1) of immersing a solid-state 226Ra containing substance and a carrier having a function of adsorbing 226Ra ions in a processing solution, and then irradiating the processing solution with ultrasonic waves.

Abstract: An information processing terminal includes a display unit and a control unit. The display unit includes a plurality of displays. The control unit can display screens on the displays in a plurality of display modes in which display forms on the displays are different. The control unit displays a display mode change-over switch within the screens. When the display mode change-over switch is designated, the control unit displays a list of only those display modes to which a current display mode can be changed so that each display mode can be designated. Further, the control unit displays, when one display mode is designated, the screens in the designated display mode.

Abstract: A technology that realizes a browser that is highly convenient for information processing terminals provided with a plurality of displays is provided. An information processing terminal includes a display section and a control section. The display section has a plurality of displays. The control section causes a first browser screen to appear on a first display of said display section and, if the first browser screen is locked and an operation is performed on the first browser screen, causes a second browser screen to appear on a second display of said display section.

Abstract: Provided is an information processing terminal having two screens, which can accurately measure ambient brightness. The information processing terminal includes two rectangular plate-like display devices respectively having screens connected to each other at connection sides. The information processing terminal is used with the two screens arranged horizontally or vertically. Near the side that is opposite to the connection side of one of the display devices, an illuminance sensor is disposed in a position near the top from the center of the opposite side when the two screens are arranged to be used horizontally.

Abstract: Provided is an information processing terminal that includes two cases each having a touch-panel display and coupled together by a hinge unit to be openable and closable. The hinge unit is a biaxial hinge having two parallel rotary shafts respectively connected to the two cases and located outside the displays in the axial direction of the rotary shafts.
