    • In an odor measuring apparatus, a plurality of detection outputs with respect to a sample gas is obtained by a plurality of odor sensors having different response characteristics. In an odor fractionation processing section, based on the detection outputs, it is determined which one of a plurality of predetermined odor categories the odor of the sample gas belongs to. In case of calculating an odor index from the detection outputs, the same regression line can be utilized for the same odor category. An odor index calculating section utilizes regression coefficients determined in advance for each odor category, to thereby calculate the odor index. Accordingly, without using an organoleptic test by panels, the odor index can be obtained easily and accurately.
    • 在气味测定装置中,通过具有不同响应特性的多个气味传感器获得关于取样气体的多个检测输出。 在气味分馏处理部中,基于检测输出,确定样气的气味属于多个预定气味类别中的哪一个。 在从检测输出计算气味指数的情况下,相同的回归线可用于相同的气味类别。 气味指数计算部利用针对每个气味类别预先确定的回归系数,从而计算气味指数。 因此,在不使用面板的感官试验的情况下,可以容易且准确地获得气味指数。

    • An odor measuring device has a collector tube containing an adsorbent which adsorbs sample components with odor at normal temperatures and desorbs them when heated. Flow routes for a sample gas containing sample components to be detected and an inactive gas are connected through valves to this collector tube. Initially, a sample gas containing sample components with odor is introduced into the collector tube at normal temperature such that the sample components to be detected are adsorbed to the adsorbent. Thereafter, the valves are switched such that the inactive gas is introduced into the collector tube while its temperature is increased by a heater, causing the sample components to be desorbed into the inactive gas and to be transported into an odor sensor. If odor sensors requiring oxygen for detection are used, an oxygen-containing gas such as air is mixed into the inactive gas after the latter has passed through the collector tube such that deterioration of the adsorbent by oxidation can be prevented.
    • 气味测定装置具有含有吸附剂的收集管,该吸附剂在正常温度下吸附有气味的样品成分,并在加热时解吸。 含有待检测样品组分的样品气体和非活性气体的流动路径通过阀连接到该收集管。 首先,将含有气味的样品成分的样品气体在常温下引入收集管,使待检测的样品成分吸附在吸附剂上。 此后,切换阀,使得惰性气体被引入收集管中,同时通过加热器增加其温度,使得样品组分被解吸到惰性气体中并被运送到气味传感器中。 如果使用需要用于检测的氧气的气味传感器,则在惰性气体通过集电管之后,诸如空气的含氧气体被混合到惰性气体中,从而可以防止吸附剂的氧化劣化。

    • A sheet feeding device avoiding diagonal feeding of a sheet for use in an image forming apparatus. The image forming apparatus includes a sheet cassette and a sheet supply roller unit positioned deviatedly with respect to a widthwise center of the cassette. The deviated position of the sheet supply roller provides rotational force to the sheet for causing diagonal feeding thereof. The sheet feeding device includes a plurality of feed rollers arrayed side by side in the widthwise direction of the sheet. One feed roller positioned close to the sheet supply roller unit provides the sheet feeding force greater than that of the remaining sheet feed roller positioned far away from the sheet supply roller for providing a linear relationship between a resultant sheet feeding force and a resultant resistive force in a direction parallel with the sheet feeding direction. The difference in sheet feeding force is provided by changing nipping pressure of the feed rollers, friction coefficient thereof, or peripheral speed thereof.
    • 一种片材馈送装置,避免了用于图像形成装置的片材的对角线馈送。 图像形成装置包括相对于盒的宽度方向中心偏离的片材盒和片材供应辊单元。 片材供应辊的偏离位置为片材提供旋转力,以使其对角线进给。 片材进给装置包括在片材的宽度方向上并排排列的多个进给辊。 位于纸张供应辊单元附近的一个进料辊提供的纸张进给力大于远离纸张供应辊的剩余纸张进给辊的纸张进给力,以便在所得到的纸张供给力和合成的阻力之间形成线性关系 与片材进给方向平行的方向。 送纸力的差异是通过改变进给辊的夹紧压力,其摩擦系数或其圆周速度来提供的。

    • An ink filter having a fine mesh structure secured to an ink supply passageway is erected at a side portion of an ink reservoir. An upper portion of the ink reservoir communicates with the atmosphere through an air filter, a lower side portion communicates with the ink supply passageway. An ink filter interrupts the ink supply passageway at an upper portion and has a predetermined height to ensure maintenance of a column of ink in the ink supply passageway. As a result of the capillary phenomenon of the ink filter on the ink, the ink fills the entire portion of the ink supply passageway located below the ink filter so that the liquid surface of the ink is above the communication portion between the ink supply passageway and the ink reservoir but below the position of the ink filter.
