Abstract: An information processing apparatus connected to multiple devices and a server via a network includes a number-of-licenses acquiring unit, a display controller, and an installation controller. The number-of-licenses acquiring unit acquires, from the server, number-of-licenses information indicating the number of licenses, which is the number based on which a user is capable of using application software. The display controller performs control to display information indicating the application software and information indicating the devices in a form of a list. The installation controller performs control to install the application software into at least one of the devices when an operation for dragging and dropping the information indicating the application software onto the information indicating the at least one device is received from the user.

Abstract: An information processing apparatus connected to a device and a server via a network includes a first acquiring unit that acquires information related to the device from the device; a second acquiring unit that acquires information about application software from the server; and a display controller that performs control to display image information expressing the device, the information about which is acquired by the first acquiring unit, and image information expressing the application software, the information about which is acquired by the second acquiring unit, in a form of a list. The display controller performs control to vary a display mode of at least one of the image information expressing the device and the image information expressing the application software between a case where the application software is installable into the device and a case where the application software is not installable into the device.

Abstract: The present invention aims to provide recycled fibers having a low dirt content and excellent appearance and strength properties derived from sanitary products. Recycled fibers having a superabsorbent polymer (SAP) content of less than 10% obtained by subjecting a sanitary product containing a cellulose pulp to a recycling process per se have good appearance, and moldings prepared by using the recycled fibers also have excellent appearance and strength properties. Further, the recycled fibers preferably have a dirt area fraction of 50,000 mm2/m2 or less when determined by a staining assay using cobalt (II) chloride hexahydrate, and a Canadian standard freeness of 600 ml or more.

Abstract: To definitely remove stains in a small and narrow clearance. Thread 2 is spirally wound around a wire 1 formed by material with plasticity, the two or more thread-wound wires obtained are twisted together in spirals to bring the thread 2 in close contact with the wire 1 and the overall diameter is held to be small. In addition, with the winding thread, spiral narrow-width protrusions and recesses are formed, with the thread-wound wire, spiral wide-width protrusions and recesses are formed, and by crossing these and allowing a large number of small and large protrusions and recesses to be mixed, chances to catch removed matters are increased, and a satisfactory scratching condition is achieved.
