    Abstract: Method and sensor for measuring accurate measurement of NOx concentration in an exhaust gas containing O2,H2O, CO2 and NOx and a NOx gas concentration sensor. A first oxygen pump cell sufficiently pumps out oxygen in a measurement gas such as not to decompose NOx. A pair of electrodes is provided on an inner side and an outer side of a second measurement chamber into which the gas is introduced from a first measurement chamber via a diffusion resistance. A voltage is impressed across the paired electrodes for decomposing NOx in the second measurement chamber to dissociate oxygen which causes the current to flow in a second oxygen ion pump cell. The NOx gas concentration is measured for this current. The voltage impressed across the paired electrodes of the second oxygen ion pump cell is set so as not to dissociate H2O and CO2 present in the second measurement chamber.

    Abstract: An ultrasonic-wave propagation time measuring method which enables determination of accurate propagation time, a gas-pressure measuring method, a gas-flow-rate measuring method, and a gas sensor. A reception wave which has been transmitted and received by an ultrasonic element 5 is shaped and integrated by an integration circuit 67 to obtain an integral value. A peak value of the integral value is held by a peak-hold circuit 39. As to detection of gas concentration, a resistance-voltage-division circuit 41 sets a reference value on the basis of the peak value, and a point in time when the integral value of the reception wave is judged by a comparator 43 to have reached the reference value is regarded as an arrival time. Subsequently, a gas concentration is detected on the basis of a period between the emission time and the arrival time. As to detection of gas pressure and flow rate, the gas pressure is detected on the basis of the peak value, and further, the gas flow rate is calculated on the basis of the gas pressure.

    Abstract: When a sensor has deteriorated, the propagation time T1′ of a first reflection wave becomes greater than the propagation time T1 of a first reflection wave as measured in a new sensor. If measurement of the concentration of a specific gas is based on the propagation time T1 of the first reflection wave as measured in the new sensor, gas concentration cannot be determined accurately. By contrast, a reflection wave other than the first reflection wave (for example, a second reflection wave) is merely reflected off the surface of the ultrasonic element and is not affected by the internal structure of the ultrasonic element. Therefore, even when the sensor is deteriorated, the propagation time T2, T2′ of the second reflection wave exhibits less variation and is less susceptible to deterioration of the sensor. Therefore, the concentration of a specific gas is determined on the basis of the propagation time of the second reflection wave, which is less susceptible to deterioration of the sensor, instead of the propagation time of the first reflection wave, which is more susceptible to deterioration of the sensor. Thus, gas concentration can be measured accurately.

    Abstract translation: 当传感器恶化时，第一反射波的传播时间T1'变得大于在新传感器中测量的第一反射波的传播时间T1。 如果特定气体的浓度的测定是基于在新传感器中测定的第一反射波的传播时间T1，则不能准确地确定气体浓度。 相反，除了第一反射波（例如，第二反射波）之外的反射波仅仅从超声波元件的表面反射，并且不受超声波元件的内部结构的影响。 因此，即使在传感器劣化的情况下，第二反射波的传播时间T2'T2'变化较小，也不易受传感器劣化的影响。 因此，特定气体的浓度基于不易受传感器劣化的第二反射波的传播时间而不是更容易劣化的第一反射波的传播时间而确定 的传感器。 因此，可以准确测量气体浓度。

    Abstract: An NOx sensor capable of accurately determining the concentration of NOx contained in a gas to be analyzed (measurement gas) using a simple circuit. The NOx sensor includes a first measurement space and a second measurement space. The first measurement space communicates with the measurement gas via a first diffusion controlling layer, and the second measurement space communicates with the first measurement space via a second diffusion controlling layer. A first pumping current IP1 is controlled such that an output from a Vs cell is used as a reference voltage VC0 to control the amount of oxygen flowing into the second measurement space at a constant level. A constant voltage is applied to the second pumping cell so as to decompose the NOx component of the measurement gas contained in the second measurement space, and to pump out the resulting oxygen from the second measurement space. Accordingly, the concentration of NOx contained in the measurement gas can be obtained from second pumping current IP2. The electrode of the Vs cell located on the side of the first measurement space is formed around the periphery of or on a portion of the diffusion controlling layer of the Vs cell. As a result, the amount of oxygen flowing from the first measurement space into the second measurement space can be accurately determined by means of the Vs cell. Also, the NOx concentration can be accurately determined without the need for compensation.

    Abstract: A blood collection device having a blood-collecting tube, a needle, a blood container connected to the needle by the blood-collecting tube. The blood container has a blood-storing space containing anticoagulant solution. Two blood-component containers and an erythrocyte-preserving solution container are connected to the blood container by a blood-component supplying tube and a tube. The containers are made of soft material. A branching member is coupled to the blood-collecting tube and located between the blood container and the needle. A tube branching from the blood-collecting tube is connected to a filter. The filter allows passage of gas but substantially prevents passage of blood, bacteria, microorganism and the like. A flow stopper connects the blood-collecting tube to the filter. The flow stopper comprises a breakable member closing the branch tube. When the breakable member is broken, the branch tube communicates with the filter.
