    • A flow rate detector mechanism using variable Venturi therein, comprising: a variable flow rate generator, comprising: a core 11; and a variable Venturi 12; wherein a throat (flow passage) cross-sectional area defined between the core and the venturi is able to be changed by shifting relative positions of the core and the venturi in a direction of axes thereof, and further comprising a flow rate calculation processing portion 30 for calculating a flow rate based on the relative positions in the direction of the axes thereof and for outputting the calculated flow rate, thereby continuously changing the constant flow rate, without occurrence of any disturbance therein. Further, with an exhaust gas sampling method applying the flow rate detector mechanism using variable Venturi, CVS flow rate is changed within the range of the phases of measure modes, so as to make small the difference between the peak dew point in the bag and the final dew point in the bag, as well as to causethe final dew point to approach the temperature at which the bag is kept. Therefore, the dilution ratio of the final dew point is decreased, so as to improve the accuracy in analysis.
    • 一种在其中使用可变文丘里管的流量检测器机构,包括:可变流量发生器,包括:芯11; 和可变文丘里12; 其特征在于,在所述芯体和文氏管之间形成的喉部(流路)截面积能够通过沿其轴方向移动所述芯体和文氏管的相对位置而变化,还包括流量计算处理部30 用于计算基于其轴方向上的相对位置的流量并输出所计算的流量,从而连续地改变恒定流量,而不发生任何干扰。 此外,利用使用可变文丘里管的流量检测器机构的排气采样方法,CVS流量在测量模式的相位的范围内变化,从而使袋中的峰值露点与 袋中的最终露点,以及最终露点接近保持袋的温度。 因此,最终露点的稀释比降低,从而提高分析精度。

    • Data communication is carried out between nodes each not having a global address. In a network management system in which a first network and a second network which have the different address systems are connected to each other through an address translator, each of the first and second networks has a node and a management protocol proxy; and each of the management protocol proxies includes a management protocol proxy data generating unit for treating, as management protocol proxy data, a transmission source address, a transmission destination address and data in a protocol data unit which are contained in a packet of a management protocol sent from the associated one of the nodes, and an address translation unit for translating the address information in the protocol data unit contained in the management protocol proxy data sent from the other management protocol proxy.
    • 在不具有全局地址的节点之间进行数据通信。 在具有不同地址系统的第一网络和第二网络通过地址转换器相互连接的网络管理系统中,第一和第二网络中的每一个具有节点和管理协议代理; 并且每个管理协议代理包括管理协议代理数据生成单元,用于作为管理协议代理数据处理包含在管理协议的分组中的协议数据单元中的传输源地址,发送目的地地址和数据 从相关联的一个节点发送的地址转换单元,以及用于翻译包含在从其他管理协议代理发送的管理协议代理数据中的协议数据单元中的地址信息的地址转换单元。
