摘要： A method and an apparatus are provided for measuring the amount of entrained gases in a liquid sample. A conduit defining a volume is provided. The conduit has an inlet at a lower end thereof and an outlet at an upper end thereof. Liquid sample is made to flow into the inlet, through the conduit, and out of the outlet. The weight of the liquid sample in the conduit is determined during a flow of liquid sample through the conduit to obtain a first measurement. Thereafter, a difference between the first measurement and a predetermined weight value representing a weight of the same liquid sample flowing through the conduit but containing no entrained gases is determined to obtain a calculated weight of entrained gases in the liquid sample flowing through the conduit.

摘要： A sample gas is introduced into a collecting pipe filled with a collecting agent to collect odor components therein, and a gas, such as nitrogen gas, is introduced into the collecting pipe to remove moisture and so on. Then, a heater is heated to raise a temperature of the collecting pipe so that a part of the odor components adsorbed by the collecting agent is separated therefrom, and then, a carrier gas is supplied to the collecting pipe to send the separated odor components to a sensor. After a predetermined time has passed, the heater is further heated to send the separated odor components to the sensor. The heater may be further increased. Thus, an output information of the gas sensor in one cycle of measurement can be increased.

摘要： The present invention relates to an apparatus for measuring and displaying a noxious waste gas exhausted from a vehicle in real time through an electrical method instead of conventional chemical one, and controlling an amount of fuel to feed an engine with based on the measurement result to adjust an amount of noxious gas generated. A sensor, which is an element of the present invention, comprises a porous ceramic and a pair of electrodes to apply a voltage across two sides of the porous ceramic. A whole system for controlling an amount of fuel to burn, comprises the sensor, which is installed onto an exhaust pipe, generating a leakage current proportional to an amount of conductive particles contained in a waste gas; a measuring unit computing an amount of gas composition based on the generated leakage current; a controlling unit adjusting an amount of fuel to be fed into the engine from a fuel tank based on the computed value for the amount of gas composition; and a displaying unit displaying the computed values numerically or turning on a LED to alarm under the control of the controlling unit if one of the computed values exceeds a preset limit.

摘要： An electronic odor sensor includes first and second amplifiers, a biasing network, and a device connected to receive the output signals from the first and second amplifiers. The device is configured to correlate the received output signals to the presence or absence of an odor. The first and second amplifiers have respective first and second organic semiconductor layers and are configured to produce output signals responsive to the conductivities of their respective organic semiconductor layers. The conductivities of the organic semiconductor layers are responsive to voltages applied to associated ones of the amplifiers and to the presence of the odor. The biasing network applies the voltages to the amplifiers.

摘要： 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.

摘要： A measuring system and process for measuring the size distribution of particles in an aerosol with a time-varying flow utilizing a measuring instrument that utilizes a time-invariant flow rate is provided. The process includes employing a vacuum source to establish a constant flow through the measuring instrument. The vacuum generated by the vacuum source is used to draw an aerosol stream through an inlet incorporating a second stream of relatively particle free gas. The first and/or the second stream may be adjusted so that at any instant of time, the sum of the two streams is a constant value equal to the flow rate through the measuring instrument.

摘要： 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.
