    • A method for producing deionized water by self-regenerating type electrodialysis deionization, which comprises (i) using a deionized water-producing apparatus containing an electrodialyzer comprising cation exchange membranes and anion exchange membranes alternately arranged between an anode compartment provided with an anode and a cathode compartment provided with a cathode, demineralizing compartments compartmentalized with anion exchange membranes on the anode side and compartmentalized with cation exchange membranes on the cathode side, and concentrating compartments compartmentalized with cation exchange membranes on the anode side and compartmentalized with anion exchange membranes on the cathode side, the electrodialyzer having ion exchangers accommodated in the demineralizing compartments, and (ii) applying a voltage while supplying water to be treated to the demineralizing compartments to remove impurity ions in the water to be treated, wherein at least a part of the untreated water or already treated water is withdrawn to be added to a concentrating water for recycle, a flow amount of untreated water to be introduced into the demineralizing compartments being from 2 to 5.5 to a flow amount of a concentrating water to be introduced into the concentrating compartments, a linear velocity of untreated water in the demineralizing compartments being from 0.5 to 7.0 cm/sec, and a linear velocity of a concentrating water in the concentrating compartments being from 1.2 to 20 times to the linear velocity in the demineralizing compartments.
    • 一种通过自再生型电渗析去离子体制造去离子水的方法,其包括:(i)使用含有阳离子交换膜和阴离子交换膜的电渗析器的去离子水生产装置,所述阴离子交换膜交替布置在设置有阳极和阴极的阳极室之间 隔室设有阴极,在阳极侧隔着阴离子交换膜分隔并在阳极侧隔开阳离子交换膜的脱盐室,以及在阳极侧与阴离子交换膜分隔的浓缩室,并在阴极侧隔着阴离子交换膜 所述电渗析器具有容纳在所述软化室中的离子交换器,以及(ii)在将待处理的水供应到所述去矿质隔间以施加电压以除去待处理水中的杂质离子,其中至少一部分未处理 将水或已经处理的水取出以加入到浓缩水中进行再循环,待引入脱盐室的未处理水的流量为2至5.5,以引入浓缩室中的浓缩水的流量 软化室中的未处理水的线速度为0.5-7.0cm / sec,浓缩室中浓缩水的线速度为脱盐室中的线速度的1.2〜20倍。

    • A portable information terminal including a self-positioning measuring device is provided to make reservations and obtain status information of available services from a plurality of reservation centers and a plurality of status information providers, via a communication network. Such a portable information terminal may comprise a reserving unit for accessing to a reservation center, and reservation storage for storing a reservation content of a reservation; a status information collecting and judging unit for collecting status information relating to execution of the reservation content from the status information providers via the communications network and deciding, based on collected information and position information obtained by the self-positioning device, whether to move to a location for execution of the reservation content, deciding whether the reservation content is to be changed; an alternative reservation generating unit for collecting, in the case where the status information collecting and judging unit judges that the reservation content is to be changed, information relating to an alternative reservation to show the alternative reservation; and a reservation change execution unit for canceling the current reservation and storing the alternative reservation into the reservation storage.
    • 提供一种包括自定位测量装置的便携式信息终端,经由通信网络进行预约并从多个预约中心和多个状态信息提供者获取可用服务的状态信息。 这样的便携式信息终端可以包括用于访问预约中心的预约单元和用于存储预约的预约内容的预约存储器; 状态信息收集和判断单元,用于经由通信网络从状态信息提供者处收集与预约内容的执行有关的状态信息,并且基于由所述自定位装置获取的所收集的信息和位置信息来确定是否移动到 用于执行预约内容的位置,决定是否改变预约内容; 一种备用预约生成单元,用于在状态信息收集和判断单元判断为要改变预约内容的情况下,收集与替代预约相关的信息以显示替代预约; 以及预约变更执行单元,用于取消当前预约并将备选预约存储到预约存储器中。
