    • A data storage device for storing data strings each including units of data has a plurality of memory sections each for storing therein a table, a plurality of processor elements one provided for each of the tables and a controlling unit having an internal memory in which data strings are stored. The table contains a plurality of records each including a unit of data, a first index data representative of the number of units of data of a data string which the unit of data constitutes and a second index data unique to each individual data string. The processor elements access in parallel their associated tables under control of the control unit for data storage and data retrieval. The first and index data are generated by the controller for the purpose of data storage. For retrieval of data strings: a key data string is divided into units of data; retrieval keys are produced each from a combination of one of the divided units of data and a third index data representing the number of units of data of the key data string; second index data are retrieved in parallel in the tables of the data storage device with the retrieval keys so that a single second index data common to all of the retrieved second index data is found among them; and a data string corresponding to the found common second index data is outputted from the internal memory of the storage device.
    • 一种用于存储包括数据单元的数据串的数据存储装置具有多个存储部分,每个存储部分用于在其中存储表格,为每个表格提供多个处理器元件,以及具有内部存储器的控制单元,其中数据串 被存储。 该表包含多个记录,每个记录包括数据单元,表示数据单元构成的数据串的数据单元数的第一索引数据和每个单独数据串唯一的第二索引数据。 处理器元件在用于数据存储和数据检索的控制单元的控制下并行访问其相关联的表。 第一和索引数据由控制器生成,用于数据存储。 用于检索数据串:一个关键数据串被分为数据单元; 从分割的数据单元之一的组合和表示密钥数据串的数据单元数的第三索引数据产生检索密钥; 在具有检索关键字的数据存储装置的表中并行地检索第二索引数据,使得在其中找到所有检索到的第二索引数据共同的单个第二索引数据; 并且从存储装置的内部存储器输出与所找到的公共第二索引数据相对应的数据串。

    • An instrument for measuring a refractive power includes a target, a target projecting unit, a measurement light projecting unit, a light receiving unit, a unit for performing a normal refractive power measurement, a judgment unit, and a unit for performing a high-speed refractive power measurement. The unit for performing a normal refractive power measurement measures a normal refractive power of an examined eye based on received light data. The judgment unit judges reliability of the received light data or the refractive power measurement. The unit for performing a high-speed refractive power measurement measures a refractive power of the examined eye faster than the unit for performing a normal refractive power measurement in response to a judgment result of the judgment unit.
    • 用于测量屈光度的仪器包括目标,目标投影单元,测量光投射单元,光接收单元,用于执行正常屈光力测量的单元,判断单元和用于执行高速 屈光度测量。 用于执行正常屈光力测量的单元基于接收到的光数据测量被检眼的正常屈光度。 判断单元判断所接收的光数据的屈光力测量的可靠性。 用于执行高速屈光力测量的单元响应于判断单元的判断结果,比用于执行正常屈光力测量的单元更快地测量检查眼睛的屈光度。
