    • A software copying system which enables copyrighted software recorded in a master storage medium to be copied to a user's target storage medium in a legitimate manner. A contents identifier reading unit reads out a software identifier from the master storage medium, while a storage medium identifier reading unit reads out a storage medium identifier from the target storage medium., The two identifiers are then sent to a central site which manages licenses for the right to copy software products. At the central site, a signature generating unit produces a first signature from those identifiers and sends it back to the user's site, where a signature writing unit writes the received signature into the target storage medium. A signature generating/comparing unit produces a second signature out of the same identifiers as those sent to the central site, and compares it with the first signature stored in the target storage medium. A data copying unit copies the subject software data file from the master storage medium to the target storage medium, only when the first and second signatures coincide with each other.
    • 一种软件复制系统,其使记录在主存储介质中的版权软件以合法方式复制到用户的目标存储介质。 内容标识符读取单元从主存储介质读出软件标识符,而存储介质标识符读取单元从目标存储介质读出存储介质标识符,然后将两个标识符发送到管理许可证的中心站点 复制软件产品的权利。 在中心站点,签名生成单元从这些标识符生成第一个签名,并将其发送回用户的站点,其中签名写入单元将接收到的签名写入目标存储介质。 签名生成/比较单元产生与发送到中心站点的标识符相同的标识符,并将其与存储在目标存储介质中的第一签名进行比较。 只有当第一和第二签名彼此一致时,数据复制单元将主体软件数据文件从主存储介质复制到目标存储介质。

    • An apparatus for automatically controlling tunnel face hydraulic pressure in a hydraulic chamber defined by a rotary cutter head and bulkhead in a shield type excavator used in hydraulic tunnel boring system including a pipe for feeding a hydraulic material with a feeding pump from a reservoir to the chamber and a pipe for discharging a mixture of the fed hydraulic material with ground formations excavated by the cutter head from the chamber to the reservoir with a discharging pump. The apparatus substantially comprises a pressure gauge for measuring actual hydraulic pressure in the chamber, a pressure regulating valve in the feeding pipe as disposed close to the chamber, a first pressure regulator in which a predetermined feeding pressure is preset for comparing the actual pressure measured by the gauge with the predetermined feeding pressure and controllably operating the valve responsive to any difference between the pressures compared in the first regulator, and a second pressure regulator in which a predetermined pumping pressure is preset for comparing the actual pressure with the predetermined pumping pressure and controlling pumping rate of the feeding pump responsive to any difference between the pressures compared in the second regulator. The predetermined pumping pressure preset in the second regulator is preferrably made slightly higher than the predetermined feeding pressure preset in the first regulator.

    • An optical switching device comprising a plurality of mechanical optical switching structures having one to several movable optical fibers and one to several fixed optical fibers installed in a housing in which a refractive index matching oil is filled up and immerses the structures. Each of the structures has an electromagnetic actuator to reciprocate open ends of the movable optical fibers relatively to open ends of the fixed optical fibers and to connect/disconnect optical paths. Ends opposite to the open ends of the movable optical fibers and the fixed optical fibers are drawn out through ports located on the housing so that a certain number of optical fibers among the optical fibers drawn out serve as input optical fibers, while a certain number of optical fibers among the other optical fibers drawn out serve as output optical fibers, to constitute the optical switching device of m×n type, in which m is the number of input paths and n is the number of output paths, providing a small-sized optical switching device having variable numbers of input/output paths.
    • 一种光学开关装置,包括多个机械光学开关结构,其具有一个至几个可移动光纤和一个至几个固定的光纤,该光纤安装在壳体中,其中折射率匹配油被填充并浸没在该结构中。 每个结构具有电磁致动器,以相对于固定光纤的开口端往复移动可动光纤的开口端并连接/断开光路。 可移动光纤和固定光纤的开口端的相反端部通过位于壳体上的端口被抽出,使得被拉出的光纤中的一定数量的光纤用作输入光纤,而一定数量的 引出的其他光纤中的光纤作为输出光纤,构成mxn型光开关器件,其中m为输入通路数,n为输出路径数,提供小尺寸光开关 设备具有可变数量的输入/输出路径。
