    • PURPOSE: To improve efficiency of a storage pump in the stage of filtration and working efficiency of filtration by executing filtration while stirring and moving circulatory filtration sand charged in a central cylinder having many small perforations for passing water on the surface and in the longitudinal direction of the cylinder.
      CONSTITUTION: Many small perforations 1c for passing water are provided on the surface of a central cylinder 1 perforated with a breadth equal to the diameter of a water passing hole 2A down to the bottom of the cylinder 1, and a revolvable central shaft 1A attached with blades 1B is provided to the center of the cylinder 1. Filtration sand is charged in the cylinder 1, and effective filtration is performed by moving the sand circulatory and stirring. A central cover cylinder 2 having obliquely perforated water passing holes 2A on the surface is combined lightly slidably to the external side of the cylinder 1. Further, projections 2B for guiding a floating ring 5 and an adjusting weight 5A are provided parallely above the cylinder 1. A storage pump or an air pump, etc. is connected with a mouth piece for pipe 4C of the cylinder 1, and water is sucked from a water passing small perforations 4B. The water is circulated to the upper part repeatedly, continuing until the water is washed clean.

    • A searchable encryption resistant to frequency analysis. A conversion rule management device generates a conversion rule table associating a search keyword with a conversion keyword group. Based on the conversion rule table, a data registration device generates registration data associating encrypted data with an encrypted keyword, and registers the registration data in a server device. An information processing device obtains from the conversion rule table a conversion keyword group associated with a specified search keyword, generates an encrypted keyword group, and requests a data search by specifying the encrypted keyword group. Using as a search key an encrypted keyword included in the encrypted keyword group, the server device searches for encrypted data associated with the search key, and returns searched encrypted data. The information processing device decrypts the searched encrypted data, and outputs as a search result search data obtained by decryption.
    • 可搜索的加密功能可抵抗频率分析。 转换规则管理装置生成将搜索关键字与转换关键字组关联的转换规则表。 基于转换规则表,数据登记装置生成将加密数据与加密关键词相关联的登记数据,并将注册数据登记在服务器装置中。 信息处理装置从转换规则表获得与指定搜索关键字相关联的转换关键字组,生成加密关键字组,并通过指定加密的关键字组来请求数据搜索。 使用包括在加密关键字组中的加密关键字作为搜索关键字,服务器设备搜索与搜索关键字相关联的加密数据,并返回搜索到的加密数据。 信息处理装置对所搜索的加密数据进行解密,并输出作为通过解密得到的搜索结果的搜索结果。
