    • A method of generating access-control lists executable by a system and derived from access-control rules supplied for insuring security of an operation system is presented. The method includes the steps of inputting access-manager-type-group information, access-target-type-group information, and organizational-structure information, inputting access-control rules each comprised of an access-manager type, an access-target type, and an action in order to represent security guidelines of the system, inputting constraint conditions relating to the organizational structure of the system, extracting access managers and access targets from the access-manager-type-group information and the access-target-type-group information, respectively, with respect to the access-manager type and the access-target type included in each of the access-control rules, checking the constraint conditions with regard to all the combinations between the extracted access managers and the extracted access targets, and generating access-control lists comprised of such an access manager, an access target, and an action as to satisfy the constraint conditions.
    • 提出了一种生成可由系统执行并且从为操作系统的安全性提供的访问控制规则派生的访问控制列表的方法。 该方法包括以下步骤:输入访问管理器类型组信息,访问目标类型组信息和组织结构信息,输入访问控制规则,每个访问控制规则由访问管理器类型,访问目标类型 以及为了表示系统的安全准则,输入与系统的组织结构相关的约束条件,从访问管理器类型组信息和访问目标类型组信息中提取访问管理器和访问目标的动作, 组信息分别针对包括在每个访问控制规则中的访问管理器类型和访问目标类型,检查关于所提取的访问管理器和提取的访问目标之间的所有组合的约束条件, 以及生成由这样的访问管理器,访问目标和用于满足约束条件的动作组成的访问控制列表。

    • A polyester elastomer composition comprising a polyester block copolymer and a compound having, in one molecule, not less than two functional groups capable of reacting with a terminal group of the polyester block copolymer, and showing (A) a weight loss (volatility) at 150.degree. C., 2 hours of not more than 0.4% and (B) a gelation degree (gel fraction) at 250.degree. C., 4 hours of not more than 50%; and a polyester elastomer composition comprising a polyester block copolymer, a compound having, in one molecule, not less than two functional groups capable of reacting with a terminal group of the polyester block copolymer and a chain extender heating loss percentage satisfying the formula: (W1-W2)/W1.ltoreq.0.1, and a stabilizer comprising a tertiary amine as a part of its skeleton. From such composition, an elastomer molded product having fine mechanical strength, heat resistance and resistance to hydrolysis, which shows less volatility during heating and less gel and bleed out, can be obtained.
    • 一种聚酯弹性体组合物,其包含聚酯嵌段共聚物和在一个分子中具有不少于两个能够与聚酯嵌段共聚物的末端基反应的官能团的化合物,并且显示(A)150重量份的挥发性 ℃,2小时不超过0.4%,(B)凝胶化程度(凝胶分数)在250℃,4小时不大于50%; 以及聚酯弹性体组合物,其包含聚酯嵌段共聚物,在一个分子中具有不少于两个能够与聚酯嵌段共聚物的末端基反应的官能团的化合物和满足以下式的扩链剂加热损失百分比:(W1 -W2)/ W1 <0.1,以及包含作为其骨架的一部分的叔胺的稳定剂。 通过这样的组合物,可以获得具有机械强度,耐热性和耐水解性的弹性体成型体,其在加热过程中挥发性较差,凝胶渗出少。

    • A front loading disc player for automatically delivering a disc onto a turntable and playing back the disc includes a disc delivery mechanism for delivering the disc. The disc delivery mechanisms has two trays for carrying respective discs, juxtaposed in a direction substantially normal to the disc carrying surface of the turntable and movable into a projected position out of the player housing and a retracted position in the player housing, and a guide and driver means for guiding and moving the trays into the playback position, the retracted position, and the projected position. While one of the trays is in the playback position, the other tray is positioned in either the stored position or the projected position. While the disc delivered by one of the trays onto the turntable is being played back, therefore, the disc on the other tray can be replaced with a new disc, so that a number of discs can successively be played back.
    • 用于将光盘自动传送到转台并播放盘的前装载盘播放器包括用于传送盘的盘传送机构。 盘传送机构具有两个托盘,用于承载相应的盘,其大致垂直于转台的盘承载表面的方向并置,并且可移动到投球机壳体内的突出位置和播放器壳体中的缩回位置,以及引导件和 用于将托盘引导和移动到播放位置,缩回位置和突出位置的驱动器装置。 当其中一个托盘处于播放位置时,另一个托盘位于存储位置或投影位置。 当其中一个托盘传送到转台上的光盘正在播放时,因此,另一个托盘上的光盘可以用新的光盘替换,从而可以连续播放多个光盘。
