摘要： An information service system including a plurality of receiving stations and information service facilities. The information service facilities include a memory circuit which stores beforehand a distribution destination information set of receiving station identifiers allocated to the receiving stations, distribution destination information set being disposed in a predetermined order within the memory circuit, a memory circuit for storing a plurality of information to be supplied to receiving stations, an enciphering circuit for generating an enciphering key for optical receiving stations within a group which performs broadcast communications, and enciphering the service information with the enciphering key, and a circuit for transmitting the enciphered service information and service destination codes of service destination receiving stations encoded from the distribution destination information set, through broadcast communications. Each receiving station includes a memory circuit for storing beforehand its own identifier and the distribution destination information set of the group which performs broadcast communications, a receiver unit for receiving the enciphered service information and the service destination codes from the information service facilities, and a deciphering circuit for generating a deciphering key corresponding to the distribution destination information set in accordance with the received service destination codes and the corresponding, and previously stored distribution destination information, only when the own identifier of the receiving station is contained in the service destination codes, and the deciphering the enciphered service information with the deciphering key.
摘要翻译：一种包括多个接收站和信息服务设施的信息服务系统。信息服务设备包括预先存储分配给接收站的接收站标识符的分配目的地信息集合的存储电路，存储电路内以预定顺序设置的分发目的地信息集，存储多个信息的存储电路提供给接收站的加密电路，用于产生用于执行广播通信的组内的光接收站的加密密钥和用加密密钥加密服务信息的加密密钥，以及用于发送加密服务信息和服务目的地代码的电路通过广播通信从分发目的地信息集合编码的服务目的地接收站。每个接收站包括用于预先存储其自己的标识符和执行广播通信的组的分发目的地信息集的存储器电路，用于从信息服务设施接收加密服务信息和服务目的地代码的接收器单元，以及解密电路，用于仅当所述接收站的自身标识符包含在所述服务目的地代码中时才产生与根据所接收的服务目的地代码和所述相应的和预先存储的分发目的地信息所设定的分发目的地信息相对应的解密密钥，以及用解密密钥对加密的服务信息进行解密。

摘要： A cooling liquid conducting out device having an outlet chamber which is partially filled with cooling liquid drained from the rotor of a rotary electric machine constructed such that the strength of collision of the cooling liquid with the inner walls of the outlet chamber is made small to prevent cavitation in the discharging section of a cooling liquid supplying and draining pipe. According to another aspect of the invention, the device is provided with a cooling liquid containing member which is disposed surrounding the discharging section of the supplying and draining pipe, which is maintained filled with the cooling liquid discharged through the discharging section, and which has discharging paths communicating with the outlet chamber. In addition to the discharging paths, conducting out passages for conducting the cooling liquid out of the containing member are provided to cause the cooling liquid thus passing through the conducting out paths to collide with the cooling liquid discharged through the discharging paths. Limiting members suchs are thread seals are provided in the discharging paths to reduce the amount of cooling liquid passing through the discharging paths.
摘要翻译：一种冷却液导出装置，具有出口室，其部分地填充有从旋转电机的转子排出的冷却液体，其被构造成使得冷却液体与出口室的内壁的碰撞强度较小，以防止冷却液供给排水管的排出部的气蚀。根据本发明的另一方面，该装置设置有冷却液容纳部件，该冷却液容纳部件设置在供给排出管的排出部周围，该排出部保持充满通过排出部排出的冷却液，并具有排出与出口室连通的路径。除了排出路径之外，设置用于将冷却液导出的容纳构件的导出通路，使冷却液通过导出路径与与排出路径排出的冷却液碰撞。在排出路径上设有限位构件，螺纹密封件，以减少通过排出路径的冷却液的量。
