    • In response to a request from a central processing unit (CPU) 11 (i.e., firmware) of a node 10, a transfer control unit 14a of a direct memory access (DMA) controller 14 transmits a message and data to another discretionary node 3 by way of a serial bus 1, a switch 2 or the like. In this event, the firmware stores data to be transmitted, a message, and a descriptor thereof in memory 12. In the case of requesting the transmission of the message, the descriptor contains a flag indicating “whether or not there is a need to wait for a response from the data transmission destination”. If the flag is set to ON, the transfer control unit 14a notifies the firmware of a simulated completion immediately instead of waiting for a completion response from the transmission destination node 3.
    • 响应于来自节点10的中央处理单元(CPU)11(即固件)的请求,直接存储器访问(DMA)控制器14的传送控制单元14a将消息和数据发送到另一个可选节点3 通过串行总线1,开关2等。 在这种情况下,固件将要发送的数据,消息及其描述符存储在存储器12中。 在请求发送消息的情况下,描述符包含指示“是否需要等待来自数据发送目的地的响应”的标志。 如果标志设置为ON,则传送控制单元14a立即通知固件仿真完成,而不是等待来自发送目的地节点3的完成响应。

    • A construction of a fluid-filled vibration damping device provided with an air chamber for applying an air pressure capable of increasing the pressure of a fluid in a fluid chamber is realized advantageously in industry. An air chamber is formed between a cylindrical member and a bottom member forming a second mounting member, and a seal protrusion that is caused to fall easily to the inside of the air chamber is interposed between these elements. In the state in which the air chamber is formed, the cylindrical member and the bottom member are brought close to each other and lapped on each other, by which the volume of the air chamber is decreased by an amount corresponding to the approach amount of the elements and the volume amount of the seal protrusion entering into the air chamber due to falling, and thereby the internal pressure of the air chamber is increased.
    • 在工业上有利地实现了具有用于施加能够增加流体室中的流体的压力的空气压力的空气室的流体填充减振装置的结构。 在圆柱形构件和形成第二安装构件的底部构件之间形成空气室,并且容易地落在空气室内部的密封突起插入在这些元件之间。 在形成空气室的状态下,使圆柱形构件和底部构件彼此靠近并且彼此搭接,由此使空气室的体积减小相当于空气室的接近量的量 元件和由于下落而进入空气室的密封突起的体积量,从而增加了空气室的内部压力。
