    • A protocol translation device realizes the merit of communications via the T/TCP protocol even if only one of devices in communication is compatible with T/TCP. The protocol translation device conducts protocol translation to relay communication packets sent and received between a TCP channel and a T/TCP channel, including a means for translating a T/TCP packet into a TCP packet by deleting a CC option and a CCnew option from the T/TCP packet, a means for translating a TCP packet into a T/TCP packet by adding CC, CCnew and/or CCecho options to the TCP packet and setting a CC value, and a means for assigning a value that is 16 bytes less than the maximum size of the packet to an MSS option for a communication device that communicates by the TCP protocol and instructing the communication device to transmit data with a packet that is 16 bytes or more smaller than the maximum size of the packet.
    • 即使只有一个通信设备与T / TCP兼容,协议转换设备通过T / TCP协议实现通信的优点。 协议翻译装置进行协议转换以中继在TCP信道和T / TCP信道之间发送和接收的通信分组,包括通过删除CC选项和CCnew选项将T / TCP分组转换成TCP分组的装置, T / TCP数据包,通过将TCP,CCnew和/或CCecho选项添加到TCP数据包并设置CC值来将TCP数据包转换为T / TCP数据包的装置,以及用于分配少于16个字节的值的装置 比通过TCP协议通信的通信设备的分组的MSS选项的最大大小,并且指示通信设备使用比分组的最大大小小16字节或更小的分组来发送数据。

    • A bush assembly includes an inner cylindrical member for supporting an elongated member, a rigid sleeve slideably fixed to the outer surface of the inner cylindrical member via a slipping member, and an outer cylindrical member fixed to the outer surface of the rigid sleeve via an elastic member. The rigid sleeve has a greater diameter portion at one end thereof so that an annular space is formed between the greater diameter portion and one end of the inner cylindrical member. The bush assembly further includes a sealing member which is disposed in the annular space for preventing muddy water or the like from getting into the interfaces between the slipping member and the inner cylindrical member and between the slipping member and the rigid sleeve. The sealing member includes an outer portion fixed to the rigid sleeve, an inner portion being brought into contact with the inner cylindrical member, and an intermediate portion arranged therebetween. The intermediate portion has an annular corrugated wall which extends between the inner and outer portions.
    • 衬套组件包括用于支撑细长构件的内圆柱形构件,通过滑动构件可滑动地固定到内圆柱构件的外表面的刚性套筒,以及通过弹性件固定到刚性套筒的外表面的外圆筒构件 会员。 刚性套筒在其一端具有较大的直径部分,使得在内圆柱形构件的较大直径部分和一端之间形成环形空间。 衬套组件还包括密封构件,其设置在环形空间中,用于防止泥水等进入滑动构件和内圆柱构件之间以及滑动构件和刚性套筒之间的界面。 密封构件包括固定到刚性套筒的外部部分,与内部圆柱形部件接触的内部部分和布置在其间的中间部分。 中间部分具有在内部和外部之间延伸的环形波纹壁。

    • A communication control apparatus that controls communication via a network between a first communication apparatus for communicating via a virtual communication channel and a second communication apparatus for transmitting a communication request with the first communication apparatus including a storage unit that stores access control policy defining allowance or denial of access to the first communication apparatus, an establishment unit that establishes the virtual communication channel with the first communication apparatus, an authentication unit that authenticates the second communication apparatus based on the communication request received from the second communication apparatus, an access control unit that refers to the access control policy and evaluates whether to allow or deny access from the authenticated second communication apparatus to the first communication apparatus, and a transfer unit that transfers the received communication request to the first communication apparatus when the access control unit evaluates that the access is allowed.
