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 coherence indicator of received signals is calculated for pixels with a small amount of calculation, and a high-quality ultrasound image is obtained. A plurality of types of images in which a sound speed for beamforming is changed into a plurality of types are generated. By arranging, in order of the sound speed for beamforming, signal intensities of the pixels at corresponding positions between the plurality of types of images, a change in signal intensities in a direction of the sound speed for beamforming is obtained. A coherence indicator representing coherence of the received signals used for beamforming of the pixels is calculated based on the obtained change in the signal intensities.

Abstract: An ultrasonic imaging apparatus is capable of removing noise for each tissue from a received signal of a living tissue in which a plurality of tissues are intricately intertwined, and suppressing artifacts even at a tissue boundary. An evaluator receives one or more time-series ultrasonic signals obtained by receiving an ultrasonic wave from a subject by an ultrasonic probe after transmitting an ultrasonic wave, and generates a filter control signal for setting a characteristic value of a filter for removing noise contained in the ultrasonic signal, for a time-series direction of the ultrasonic signal. A filter processor removes the noise by processing the ultrasonic signal of the corresponding signal characteristic value by the filter having the characteristic value set based on the filter control signal. A smoothing processor that smooths distribution of the filter control signal is disposed between the evaluator and the filter processor.
