    • A color cathode-ray tube is disclosed, which has a shadow mask facing the face plate inner surface and having slit apertures formed in a predetermined arrangement. The center-to-center distance or interval Px of the slit apertures on the horizontal axis increases as a first function along the horizontal axis from the center of the shadow mask to the periphery region thereof. The center-to-center distance or interval Sx in peripheral regions of the shadow mask remotest from the horizontal axis increases as a second function different from the first function along the horizontal axis from the vertical axis to the periphery region thereof. The first and second functions representing the respective slit aperture intervals Px and Sx are given as ##EQU1## where X is 1, 2, 3, . . . , and .alpha. and .beta. are .alpha.

    • A network relay apparatus is provided, wherein data accompanied by additional information is relayed among plural networks through input ports and output ports. In the apparatus, a deciding unit decides, from the output ports, an objective output port to which the data inputted via any one of the input ports is to be inputted, on the basis of the additional information of the data inputted. An output unit outputs the inputted data through the decided objective output port. A producing unit produces diagnostic data to which the additional information including information indicating the decided objective output port is added, and a providing unit provides the deciding unit with the produced diagnostic data. Further, a fault diagnostic unit is provided to determine whether a fault has occurred in the network relay apparatus on the basis of information concerning with the diagnostic data and the decided objective output port.
    • 提供一种网络中继装置,其中伴随附加信息的数据通过输入端口和输出端口在多个网络之间中继。 在该装置中,决定单元根据输入的数据的附加信息,从输出端口决定要输入通过输入端口输入的数据的目标输出端口。 输出单元通过确定的目标输出端口输出输入的数据。 生产单元产生诊断数据,附加信息包括指示所确定的目标输出端口的信息,并且提供单元向所述判定单元提供所产生的诊断数据。 此外,提供故障诊断单元,以基于与诊断数据和所确定的目标输出端口有关的信息来确定网络中继装置中是否发生故障。

    • A personal identification system includes local computer systems to be operated by authorized users, a remote computer system having common resources (data, hardware, etc.) to be accessed from the local computer systems, and a personal verification system having a database section which stores passwords of each authorized user and physical characteristics data corresponding to each password. When a user made a request to a local computer system for the use of the common resources of the remote computer system, physical characteristics (a fingerprint etc.) of the user is scanned by a scanning section of the local computer system, and characteristics data generated based on the scanned physical characteristics is sent to the personal verification system. The personal verification system searches the database section for a password using the received characteristics data as a key, and sends the searched password to the local computer system. The local computer system which received the password sends the password to the remote computer system for personal identification of the user. Passwords of the authorized users are managed solely by the personal verification system, thereby the user is allowed to make access to the common resources of the remote computer system easily and freely without the need of memorizing and inputting a complicated password.
    • 个人识别系统包括由授权用户操作的本地计算机系统,具有要从本地计算机系统访问的共同资源(数据,硬件等)的远程计算机系统,以及具有数据库部分的个人验证系统,该数据库部分存储 每个授权用户的密码和与每个密码对应的物理特征数据。 当用户向本地计算机系统请求使用远程计算机系统的公共资源时,用户的物理特征(指纹等)由本地计算机系统的扫描部分扫描,特征数据 基于扫描的物理特征生成的物理特征被发送到个人验证系统。 个人验证系统使用接收到的特征数据作为密钥,在数据库部分中搜索密码,并将搜索到的密码发送到本地计算机系统。 接收密码的本地计算机系统将密码发送到远程计算机系统,用于用户的个人识别。 授权用户的密码仅由个人验证系统管理,允许用户轻松自由地访问远程计算机系统的公共资源,而不需要记忆和输入复杂的密码。
