    • A biometrics authentication device which detects body characteristics, performs verification against registered biometrics data, and performs individual authentication, by which confidentiality is improved even when biometrics data is separated, distributed and stored. A biometrics information key is created from biometrics data detected by a detection device, the biometrics data is divided into a plurality of portions, and the portions are stored on different media. The biometrics information key is stored on one media, and at the time of authentication, the separated biometrics data portions are combined and a biometrics information key is created and is compared with the biometrics information key, to judge the linked relationship. Hence confidentiality of the association of the individual separated data portions can be improved even when the biometrics data is separated, distributed and stored, contributing to prevent illicit use resulting from leakage or theft of biometrics data.
    • 一种检测身体特征的生物体认证装置,对登记的生物特征数据执行验证,并且执行个体认证,即使生物特征数据被分离,分发和存储,机密性也得到改善。 生物特征信息密钥由检测装置检测的生物特征数据创建,生物统计数据被分成多个部分,并且部分存储在不同的媒体上。 将生物识别信息密钥存储在一个媒体上,并且在认证时将分离的生物统计数据部分组合起来,生成生物统计信息密钥并与生物特征信息密钥进行比较,以判断链接关系。 因此,即使分离,分发和存储生物特征数据,也可以提高各个分离的数据部分的关联的机密性,有助于防止由于生物特征数据的泄漏或盗窃而导致的非法使用。

    • A connecting rod is formed using a method that includes providing a connecting rod blank. The connecting rod blank has a rod section disposed between a big end and a small end. The big end has a first hole generally sized to receive a crankpin of a crankshaft and at least one second hole generally sized to receive a bolt, wherein the axes of the first and second holes are generally normal to each other. The big end of the connecting rod has a dividing plane that extends through both the first and second holes. The connecting rod blank is processed by hardening at least the big end to a sufficient depth such that a first region of the big end lying between the first and second holes at the dividing plane is hardened, while leaving a substantial second region of the big end at the dividing plane generally unhardened. The connecting rod blank is further processed by splitting the big end along the dividing plane to produce a rod part fracture surface and a cap part fracture surface.
    • 使用包括提供连杆坯件的方法形成连杆。 连杆坯件具有设置在大端和小端之间的杆部。 大端具有通常尺寸适于容纳曲轴的曲柄销的第一孔,以及通常尺寸设置成容纳螺栓的至少一个第二孔,其中第一孔和第二孔的轴线大体上彼此正交。 连杆的大端具有延伸穿过第一孔和第二孔的分隔平面。 连杆坯料通过将至少大端硬化至足够的深度进行加工,使得位于分割平面处的第一和第二孔之间的大端的第一区域硬化,同时留下大端的实质的第二区域 在分界线上一般没有硬化。 通过沿分割平面分割大端进一步处理连杆坯料,以产生杆部断裂面和帽部断裂面。
