    • A public key cryptosystem is used for the authentication of a personal station (PS) which subscribes for a plurality of radio communication exchange systems. A public key of PS is registered into a public key DB of a public key management device. A private key is registered into PS. When PS moves into a service area of a certain radio communication exchange system, an exchange in that radio communication exchange system requests the public key management device for a public key of PS and makes a check for authentication of PS based on the public key cryptosystem by use of the received public key. Thereafter, when PS moves into a service area of another radio communication exchange system, an exchange in the other radio communication exchange system similarly requests the public key management device for a public key of PS and receives the same public key. The exchange in the other radio communication exchange system makes a check for authentication of PS based on the public key cryptosystem by use of the received public key. In the case where the authentication between each radio communication exchange system and PS results in success, each radio communication exchange system can determine a peculiar authentication key to inform PS of the peculiar authentication key so that the authentication of PS from that time onward is performed using the peculiar authentication key.
    • 公共密钥密码系统用于订阅多个无线电通信交换系统的个人站(PS)的认证。 PS的公钥被登记到公钥管理装置的公开密钥DB中。 私钥在PS中注册。 当PS移动到某个无线电通信交换系统的服务区域时,该无线电通信交换系统中的交换机向公钥管理装置请求公共密钥,并且基于公钥密码系统对PS的认证进行检查, 使用收到的公钥。 此后,当PS移动到另一无线电通信交换系统的服务区域时,另一无线电通信交换系统中的交换类似地向公钥管理装置请求PS的公开密钥并接收相同的公钥。 其他无线通信交换系统中的交换通过使用所接收的公开密钥来检查基于公钥密码系统的PS的认证。 在每个无线电通信交换系统和PS之间的认证成功的情况下,每个无线电通信交换系统可以确定特定的认证密钥以通知PS特有的认证密钥,使得从那时开始的PS的认证是使用 特有的认证密钥。

    • An intake passage is formed by connecting upper and lower cases 10, 20 of an intake manifold. The lower case 10 has a recessed portion 50 on an inner surface 17a. The recessed portion 50 has a deep surface 53 to which a negative pressure outlet port 42 opens, and an opening 51 is provided in an upper portion of the recessed portion 50. The upper case 20 has a projecting portion 60 extending further downwards towards the negative pressure outlet port 42 than mating surfaces 10a, 20a and projects into the recessed portion 50 through an opening 52. The projecting portion 60 is positioned above the negative pressure outlet port 42 and between the negative pressure outlet port 42 and the inner surface 17a. A lower end portion 63 of the projecting portion 60 is formed into an arc-like shape of which central portion 65 projects downwards.
    • 通过连接进气歧管的上壳体10和下壳体20形成进气通道。 下壳体10在内表面17a上具有凹部50。 凹部50具有负压出口42打开的深表面53,并且在凹部50的上部设置有开口51.上壳体20具有向下延伸朝向负的突出部分60 压力出口42比配合面10a,20a突出并通过开口52突出到凹部50.凸出部分60位于负压出口42的上方,负压出口42和内表面17a之间。 突出部分60的下端部分63形成为中心部分65向下突出的弧形形状。
