摘要： The present invention is to allow prompt and reliable synchronization of belonging information management table even in environments where there is a possibility of receiving update notification information from a plurality of wireless base stations, without needing unnecessarily large traffic for synchronization of belonging information management table. Wireless base station stores belonging information management table, to which belonging information of a terminal belonging to the base station is associated with, to new/old judgment information for judgment of new/old of update. Belonging information update unit performs update of belonging information including the new/old judgment information thereof. Further, upon receiving update notification information from other wireless base station, the belonging information update unit updates the belonging information management table based on the update notification information. The update notification information includes at least updated portion in the belonging information and new/old judgment information.

摘要： Provided is an X-ray tube which can perform stable X-ray radiation under a desired condition in a radiation region extending in a predetermined direction. Included are a base plate having an opening portion and made of alloy 426, an X-ray transmission window made of titanium foil and arranged to close the opening portion of the base plate, a flat box-like vessel portion attached to the base plate and inside of which is in a vacuum state, an X-ray target provided at the opening portion in the vessel portion, and an electron source injecting electrons to the X-ray target in the vessel portion. The electron source includes a liner cathode, a first control electrode pulling out electrons from the cathode and a second control electrode restricting radiation range of the pulled-out electrons. At this time, X-rays emitted from the X-ray window spreads radially from opening shape of the opening portion.
