    • In an additional writing format optical disk library unit or the like, the processing for automatically reorganizing a volume is carried out effectively so as to intend to reuse media. Whether the number of residual blank media surfaces in a volume is small is judged. If the number is small, media surfaces each having a low data valid rate are extracted from the volume. Valid data on the extracted media surfaces is written and added to a medium surface which is currently set as a writing target, so that data relocation is carried out. Media surfaces occupied only by invalid areas are deregistered from the volume. Further, the media surfaces deregistered from the volume are formatted. The formatted media surfaces are re-registered into the volume.
    • 在附加的写入格式的光盘库单元等中,有效地执行用于自动重组卷的处理,以便重新使用介质。 判断体积中剩余空白介质表面的数量是否小。 如果数量小,则从卷中提取各自具有低数据有效速率的介质表面。 将提取的介质表面上的有效数据写入并添加到当前设置为写入目标的介质表面,从而进行数据重定位。 仅由无效区域占用的介质表面将从卷中注销。 此外,从卷中注销的媒体表面被格式化。 格式化的媒体曲面重新注册到卷中。

    • In order to provide a technology in an ultrasonic flowmeter to efficiently penetrate through both of a wedge and a fluid pipe surface so as to contribute to more accurate measurement of a flow rate. An ultrasonic flowmeter includes an ultrasonic transmitter for launching ultrasonic pulses of a predetermined frequency into the fluid to be measured in fluid pipe from an ultrasonic transducer along a measurement line; a flow velocity distribution measurement means for measuring flow velocity distribution of the fluid to be measured in a measurement region by receiving ultrasonic echoes (reflection wave A) reflected from the measurement region among the ultrasonic pulses incident into the fluid to be measured; and a flow rate operation means for operating a flow rate of the fluid to be measured in the measurement region based on the flow velocity distribution of the fluid to be measured, and a clamp-on type is adopted. A condition to make both a distance from the ultrasonic transmitter in the wedge to the outer surface of the liquid pipe and the wall width of the fluid pipe be an integral multiple of λ/2 of the frequency used should be satisfied.
