Abstract: When a transmission timing of a downlink and a reception timing of an uplink at a radio communication node 100B are aligned, a radio communication node 100A determines an alignment value of the reception timing based on timing information used to determine transmission timing of the uplink, or an offset value from the timing information. The radio communication node 100A transmits the determined alignment value or offset value to the radio communication node 100B.

Abstract: Dilator includes a hollow shaft having a tapered portion, in which an outer diameter of a distal end is smaller than a outer diameter of a proximal end, and a main body portion which has a distal end located at the proximal end of the tapered portion, extends toward a proximal end side, and has a constant outer diameter. A spirally-arranged protruding portion which is configured of a coil body formed by winding a wire is provided on an outer peripheral surface of the tapered portion and the main body portion. The spirally-arranged protruding portion has gaps between portions adjacent to each other along a longitudinal direction of the hollow shaft. The spirally-arranged protruding portion is not joined to the tapered portion, but is joined to the main body portion at a joint part.
