Abstract: A storage apparatus includes plural trays each incorporating plural HDDs and a controller that controls access to the HDDs in response to an access request from a host apparatus. The controller also includes a table, in which standard power and a start-up power supply status are associated with each other for each of the trays, a table that manages total power required by the trays and present power consumed by the trays, and a table that defines maximum available power relative to the total power. The controller, when receiving a power-on setting request for a certain tray, judges whether or not the tray can be turned on based on the standard power for the tray and the present power, and the controller, upon determining that the tray can be turned on, turns on the tray.

Abstract: A radiation image capturing apparatus includes a cooling mechanism for causing cooling medium to flow from a rear surface side to a radiation detector to a front surface side of radiation detector through a narrow space formed between an end of the radiation detector and a casing for housing the radiation detector. It is therefore possible to cool the narrow space, as well as regions in the vicinity of the narrow space, with the cooling medium and to discharge the cooling medium from the front surface side of the radiation detector.

Abstract: A radiation image capturing apparatus includes a housing for housing a radiation detector. The housing has a wall inclined with respect to a detection surface of the radiation detector, and the wall defines a space inclined with respect to the detection surface. The space allows heat transfer medium such as air of relatively high temperatures (higher than that of outside air, for example) to rise along a slope defined by the space. If the region around the detection surface is heated to high temperatures, airflow is generated within the space, forcing the relatively high-temperature heat transfer medium away from the vicinity of the radiation detector, thereby allowing the whole radiation detector to be cooled in a uniform manner.
