Abstract: A sputtering target that can be used for forming a buffer layer that enables magnetic crystal grains in a magnetic recording layer granular film to be well separated when the magnetic recording layer granular film is stacked above a Ru underlayer. The target contains a metal and an oxide, wherein: the contained metal becomes a nonmagnetic metal including an hcp structure if the entirety of the contained metal is made into a single metal, the lattice constant “a” of the hcp structure included in the nonmagnetic metal being 2.59 ? or more and 2.72 ? or less; the contained metal includes 4 at % or more of metallic Ru relative to the whole amount of the contained metal; and the sputtering target contains 20 vol % or more and 50 vol % or less of the oxide relative to the entire sputtering target, the melting point of the contained oxide being 1700° C. or more.

Abstract: A system enables safe and prompt communication in case of accident or fire. Detecting an emergency event, detection device 10 transmits emergency event information to each floor device 30 and to monitoring center device 40. Upon receipt of emergency event information, each of floor devices 30 and monitoring center device 40 display at least emergency event information and a point(s) of emergency contact. Each of floor devices 30 and monitoring center device 40 display image information taken by camera 20 related to the detection device which has detected the emergency event. Each of floor devices 30 and monitoring center device 40 may have call with the point(s) of emergency contact when the point(s) of emergency contact displayed is touched. In the call with the point(s) of emergency contact, each of the floor devices 30 and the monitoring center device 40 transmit the image information displayed to the point(s) of emergency contact.
