Abstract: A top-blowing lance nozzle is configured to freely switch an adequate expansion condition so as to control an oxygen-blowing amount and a jetting velocity independently of each other without requiring a plurality of lance nozzles or a mechanically movable part. A lance nozzle is configured to blow refining oxygen to molten iron charged in a reaction vessel while a gas is blown from a top-blowing lance to the molten iron. One or more blowing holes for blowing a working gas are on an inner wall side surface of the nozzle, at a site where the lance nozzle has a minimum cross-sectional area in a nozzle axis direction or at a neighboring site of the site.

Abstract: A wireless communication system includes a base station and a terminal station. The base station extracts paths that have a power level that exceeds a predetermined threshold value from delay profiles of the terminal station as available paths, selects a path having a maximum power or a first path from the available paths as a reference path, calculates a time difference between an arrival time of the reference path and a predetermined maximum arrival time, and transmits a result to the terminal station as a transmission timing control signal. The terminal station adjusts the transmission timing to the base station according to the time difference. The base station transmits the transmission timing control signal only when the base station detects the reference path.

Abstract: In a method for adaptive transmission timing control, the overlooking of a base path at the side of the base station that occurs when the transmission timing offset amount changes to the extent of falling outside the current delay-profile calculation range, and the side of the mobile station fails to demodulate the control information that contains the transmission timing offset amount, is prevented. A limit is put on the transmission timing offset amount applied in a single transmission timing control iteration. Together with setting the transmission timing offset value such that the main component of the delay profile calculated from the pilot signal transmitted with offset transmission timing falls within the time range of when the current delay profile was calculated, the time range for calculating the next delay profile is shifted such that a delay profile calculated from the pilot signal transmitted with offset transmission timing falls within the shifted range, starting at the earliest component.
