    • In a method for detecting invalid electronic storage media each storing therein identification information recognized as an invalid electronic storage medium, the individual identification information on the invalid electronic storage media, grouped by hash values, is registered as a list. On the other hand, the individual identification information and hash information are assigned to each of the electronic storage media. The method reads the individual identification information and the group value information in response to a usage request for the electronic storage medium and checks if the individual identification information on the electronic storage medium is registered with the group corresponding to the hash value that was read. If the individual identification information corresponding to the hash value is found, the method judges that the requested electronic storage medium is invalid; if the individual identification information corresponding to the hash value is not found, the method judges that the requested electronic storage medium is valid.
    • 在检测无效电子存储介质的方法中,每个存储其中识别为无效电子存储介质的识别信息,将以哈希值分组的无效电子存储介质的个人识别信息作为列表登记。 另一方面,个体识别信息和散列信息被分配给每个电子存储介质。 该方法响应于电子存储介质的使用请求读取个体识别信息和组值信息,并检查电子存储介质上的个人识别信息是否与读取的哈希值对应的组注册。 如果找到与哈希值相对应的个人识别信息,则该方法判断所请求的电子存储介质无效; 如果没有找到与哈希值对应的个人识别信息,则该方法判断所请求的电子存储介质是否有效。

    • A simple technique for introducing a hybrid alignment or a homeotropic (vertical) alignment into liquid crystal films, which, by their nature, tend to have a horizontal alignment of liquid crystal molecules. The technique does not require special alignment films. A liquid crystal composition for forming a liquid crystal film contains a polymerizable liquid crystal compound and a hydrolysate of an alkoxysilane compound. The hydrolysate of the alkoxysilane compound contains a siloxane oligomer of which degree of polymerization is from 2 to 25. Furthermore, the alkoxysilane compound is a trialkoxysilane compound having a functional group. This liquid crystal film composition can be produced by hydrolyzing an alkoxysilane compound to obtain a hydrolysate and then uniformly mixing the hydrolysate with a polymerizable liquid crystal compound. Alternatively, it can be obtained by uniformly mixing the alkoxysilane compound with the polymerizable liquid crystal compound and subsequently hydrolyzing the alkoxysilane compound in the mixture. One mole of the alkoxysilane compound is preferably hydrolyzed with 0.1d to 2.0d mol of water, given that the number of alkoxyl groups in a molecule of the alkoxysilane compound is d. An optically anisotropic film can be obtained by applying the liquid crystal film composition to a base film, causing the liquid crystal molecules in the composition to align in a nematic alignment, and curing the composition. The alignment of the liquid crystal molecules in the film is preferably a nematic hybrid or nematic homeotropic (vertical) alignment.
    • 用于将混合取向或垂直(垂直)取向引入液晶膜的简单技术,其本质上倾向于具有液晶分子的水平取向。 该技术不需要特殊的取向膜。 用于形成液晶膜的液晶组合物含有可聚合液晶化合物和烷氧基硅烷化合物的水解产物。 烷氧基硅烷化合物的水解物含有聚合度为2〜25的硅氧烷低聚物。此外,烷氧基硅烷化合物为具有官能团的三烷氧基硅烷化合物。 该液晶膜组合物可以通过水解烷氧基硅烷化合物得到水解产物,然后将水解产物与可聚合液晶化合物均匀混合来制备。 或者,可以通过将烷氧基硅烷化合物与可聚合液晶化合物均匀混合,然后水解该混合物中的烷氧基硅烷化合物而获得。 考虑到烷氧基硅烷化合物的分子中的烷氧基数为d,一摩尔烷氧基硅烷化合物优选用0.1d至2.0dmol的水进行水解。 可以通过将液晶膜组合物施加到基膜上,使组合物中的液晶分子以向列取向取向并固化该组合物来获得光学各向异性膜。 膜中液晶分子的取向优选为向列混合或向列垂面(垂直)取向。
