    • 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。

    • A network interface unit couples a lattice communication network and at least one token ring network. The network interface unit includes a sequence controller which controls a token detector and a reception register so that message information received from the lattice communication network via a node apparatus connection port is looped back from the token ring network via a terminal connection port and output from the node apparatus connection port when an address detector detects that a destination address matches a stored source address, and absorbed when the address detector detects that the destination address does not match the stored source address. The network interface unit also includes a phantom signal part which outputs a detection signal via the terminal connection port when a phantom signal has been received, the phantom signal part including a set of resistors coupled to the terminal connection port, each of the resistors having a resistance that produces a detection signal having an appropriate level.
