    Abstract: A disc device of the present disclosure includes a plurality of magazine units aligned in height direction of the disc device. Each of the magazine units includes a plurality of magazine holders each storing at least one magazine, a rail that is slidable in depth direction of the disc device along a side of a housing of the disc device and has higher stiffness than the magazine holders, and a box-shaped handle mounted to a front end of the rail to extend in width direction of the disc device. The plurality of magazine holders is arranged in depth direction of the disc device. The rail holds the plurality of magazine holders at one side of the magazine holder. The handle extends from the front end of the rail toward a free-end side of the magazine holders and includes a recessed engagement portion that admits a finger in depth direction of the disc device and enables the finger to engage when each of the magazine units is pulled out in depth direction of the disc device.

    Abstract: In a radio network system containing a first radio apparatus that performs central control and a second radio apparatus, the second radio apparatus receives a first signal containing first identification information indicating a transmission source during a first reception period, receives a second signal containing second identification information indicating a transmission source during a second reception period, measures first reception information on reception of the first signal, measures second reception information on reception of the second signal, and transmits first measurement information containing the first reception information and the first identification information and second measurement information containing the second reception information and the second identification information to the first radio apparatus. When the first identification information and the second identification information are the same, the first radio apparatus compares the first reception information and the second reception information to determine whether a radio apparatus in an abnormal condition is present.

    Abstract: This position estimation system comprises a first wireless node for forming a wireless area; second wireless nodes which move within the wireless area; a plurality of third wireless nodes which are provided within the wireless area; and a position estimation device which estimates the position of the second wireless nodes on the basis of information indicating wireless reception quality at the third wireless nodes and the second wireless nodes. The position estimation device determines, for each of section areas, and on the basis of information pertaining to time resource capacity for wireless communication directed towards second wireless nodes, section areas which collect, in place of the first wireless node, information containing wireless reception quality at the second wireless nodes, and transmits, to one of third wireless nodes provided in the determined section area, and instruction to collect wireless reception quality at second wireless nodes within said section area.
