    • First 1-sound-line received signals are successively generated from an output signal of a transducer. One is selected from among the generated first 1-sound-line received signals as a 1-sound-line received signal of interest. Second 1-sound-line received signals are selected from among the generated first 1-sound-line received signals. The second 1-sound-line received signals include a 1 -sound-line received signal preceding the 1-sound-line received signal of interest and also a 1-sound-line received signal following the 1-sound-line received signal of interest. The second 1-sound-line received signals are averaged into a mean 1-sound-line received signal which corresponds to an undesired multiple-echo signal. The mean 1-sound-line received signal is subtracted from the 1-sound-line received signal of interest to remove the undesired multiple-echo signal from the 1-sound-line received signal of interest.
    • 从换能器的输出信号连续生成第一个1声线接收信号。 从所生成的第一1-声线接收信号中选择一个作为感兴趣的1-声线接收信号。 从生成的第一1声线接收信号中选择第2个1声线接收信号。 第二个1声线接收信号包括在感兴趣的1声线接收信号之前的1声线接收信号,以及跟随感兴趣的1-声线接收信号之后的1-声线接收信号 。 第二个1声线接收信号被平均为对应于不期望的多回波信号的平均1声线接收信号。 从感兴趣的1声线接收信号中减去平均1声线接收信号,以从感兴趣的1声线接收信号中去除不想要的多回波信号。

    • A DMA transfer controller for DMA transferring one page of image data without increasing a burden on a CPU is provided with address holders for holding addresses for each of a plurality of DMA channels. An address selector selects an address for an operating DMA channel and an address adding value prescriber prescribes an address adding value at an arbitrary value. An address adding value selector selects an address adding value between prescribed address adding values and a fixed adding value and an address adder adds such an address adding value to an output address value. A latch address selector selects an initial address value when initializing a DMA transfer and an address value produced after an address adding value has been added for providing such an address to address holders when DMA transfer is started.
    • 用于DMA传送一页图像数据而不增加CPU负担的DMA传送控制器提供有用于保持多个DMA通道中的每一个的地址的地址持有者。 地址选择器选择用于操作DMA通道的地址,并且地址添加值处方者规定了任意值的地址添加值。 地址添加值选择器在规定的地址相加值和固定相加值之间选择地址相加值,地址加法器将这样的地址相加值与输出地址值相加。 锁存地址选择器在初始化DMA传输时选择初始地址值,并且在DMA传输开始之后添加地址添加值之后产生的地址值来提供这样的地址给地址持有者。

    • An apparatus for diluting a solution comprises a preparation vessel for mixing a solution with a diluent to dilute the solution, a solution supply unit, a diluent supply unit, and a controller. The controller controls the solution supply unit and the diluent supply units to supply the solution and diluent into the preparation vessel in such quantity that the concentration of the diluted solution is higher than a desired concentration. The controller also calculates an additional quantity of the diluent necessary for diluting the solution in the preparation vessel to the desired concentration based on a difference between the concentration of the solution in the preparation vessel and the desired concentration, and controls the diluent supply unit to add the diluent into the preparation vessel in smaller quantity than the calculated additional quantity and repeats the calculation and addition until the solution concentration in the preparation vessel reaches the desired concentration.
    • 用于稀释溶液的装置包括用于将溶液与稀释剂混合以稀释溶液的制备容器,溶液供应单元,稀释剂供应单元和控制器。 控制器控制溶液供应单元和稀释剂供应单元以将稀释溶液的浓度高于期望浓度的量将溶液和稀释剂供应到制备容器中。 控制器还基于制剂容器中的溶液浓度与所需浓度之间的差异,计算将制剂容器中的溶液稀释至所需浓度所需的稀释剂的附加量,并控制稀释剂供应单元加入 稀释剂进入制剂容器中的量小于计算的附加量,并重复计算和添加,直到制备容器中的溶液浓度达到所需浓度。
