Abstract: An annular fan case which covers an outer periphery of a fan in an aircraft engine includes: a case body including a first composite material containing a fiber and a resin; and a containment section including a second composite material containing a fiber and a resin, the containment section being formed on an outer periphery of the case body. A resin content of the containment section is set to be lower than the resin content of the case body.

Abstract: A rebroadcast content scheduling device receives reception state information and schedules rebroadcast content, where the reception state information includes content identification information for identifying content represented by the broadcast wave received by the receiving section and indicates that the reception defection occurred in the reception of the content. Thus, the rebroadcast content scheduling device can determine to rebroadcast, as the rebroadcast content, the content that was received with many reception defections.

Abstract: A portable telephone is provided with a broadcast wave receiving section, a reception state detection section for detecting a packet loss ratio (reception defection degree) in the reception of the broadcast wave received by the broadcast wave receiving section, and a reception defection notice mail section and mail process section for transmitting a reception defection notice mail to a broadcast station if the packet loss ratio detected by the reception state detection section is larger than a predetermined value (5%), the reception defection notice mail containing (a) channel information, which identifies content represented by the broadcast wave received by the broadcast wave receiving section, and (b) reception defection occurrence time (here, transmission time in lieu), and requesting rebroadcast of the content.

Abstract: A portable terminal includes: a radio frequency receiving section for receiving main broadcast data and sub broadcast data; an electric field strength measuring section for measuring an electric field strength corresponding to a receiving condition of the radio frequency receiving section; a reception quality determining section for determining reception quality based on a comparison between the electric field strength measured by the electric field strength measuring section and a predetermined threshold of required quality; a decoder, a display section, and a speaker for reproducing the main broadcast data or sub broadcast data; and a switching section for reproducing main broadcast data corresponding to a designated channel acquired by a designated channel acquiring section, when the reception quality determining section determines the reception quality to be good, and sub broadcast data corresponding to a designated channel acquired by the designated channel acquiring section, when the reception quality d
