Abstract: Without carrying out an analysis process of a photographic image, to identify a type of a subject which a terminal device has photographed. Based on data of a timetable format, a specified display device 40 displays the video of the subject of a specified type for a specified display time. A terminal device 10 specifies a photography location and a photography time by a camera 14. Based on the data of a timetable format, an assessment is made as to whether the photography location belongs to the same area as the display device 40 and whether the photography time matches the display time of the video of the specified type subject upon the display device. If it is assessed that said match is true, it is determined that the video of the specified type subject has been photographed by the terminal device.

Abstract: To efficiently measure the positional relationship between a host terminal and a wireless tag in a terminal device. A terminal device 30: measures a first distance between a plurality of base stations 20 provided at individual reference positions and host terminal on the basis of wireless signals emitted by the base stations 20; specifies the position of the host terminal on the basis of the first distance; and specifies the position of a wireless tag 10 on the basis of information pertaining to a second distance between the wireless tag 10 and the base stations 20, said information being transmitted by base stations 20 that have received a wireless signal emitted by the wireless tag 10.

Abstract: Without carrying out an analysis process of a photographic image, to identify a type of a subject which a terminal device has photographed. On the basis of subject appearance information which specifies a display device 40 whereupon a subject video is to be displayed, a type of a subject to be displayed upon the display device, and a display time of the video of the subject of said type, a management device 20 causes the specified display device 40 to display the video of the subject of the specified type for the specified display time. A terminal device 10 specifies a photography location and a photography time at which photography has been taken by a photography unit 14.

Abstract: A scroll compressor for use in compressing gases includes a stationary scroll member having a top surface, a movable scroll member orbiting about the stationary scroll member for compressing gases together with the stationary scroll member as it orbits about the stationary scroll member, a muffler cavity formed in the stationary scroll member to increase the size of a muffler space in the scroll compressor, a discharge port formed in the center of the stationary scroll member for discharging the compressed gases, a release port formed in an offset position from the center of the stationary scroll member, a release cavity formed in the stationary scroll member and in communication with the released port, release guide passage passing through the stationary scroll member in parallel with the top surface of the stationary scroll member in communication with the release cavity, a sealed case for housing the stationary scroll member and the movable scroll member and a release pipe connected to the release guide pa

Abstract: In a scroll compressor enclosed in a casing and a movable scroll member is driven eccentrically by an electric motor, a thrust force created by the compression and applied to the movable scroll member is cancelled by a high pressure chamber which is provided between a surface of the movable scroll member and a frame member and supplied with a pressurized gas delivered from the scroll compressor. The high pressure chamber is formed into an annular shape defined by radially inner and outer tapered walls, and radially inner and outer seal rings having resilience to shrink and expand respectively are provided in the chamber for preventing leakage of the gas out of the high pressure chamber.
