摘要： PURPOSE:To reduce the power consumption of laser tube and to prolong its life by switching a laser beam emission device from a continuous operation state to an intermittent operation state automatically and reversibly when the variation rate of a measured value of corpuscle concentration decreases below a constant value. CONSTITUTION:A power source control circuit part C for a laser carries out basically the sequence of a continuous measurement mode wherein the laser beam emission device L is operated continuously. The variation rate of the measured value of the corpuscle concentration fed back from a measurement (arithmetic) circuit part D is detected by a differential arithmetic or sequential subtracting means at all times and when the variation rate is larger than the constant value, the laser beam emission device L is put in continuous operation to perform measurement continuously; when the variation rate decreases below the constant value, the laser beam emission device L is operated intermittently to perform automatic control so that the measurement is performed intermittently.

摘要： PURPOSE:To simply judge whether a particle counter is normal when required by a simple mechanism by measuring the number of particulates contained in a liquid to be inspected that is supplied from a supply line for the liquid to be inspected. CONSTITUTION:Number of particulates measuring means 1 is provided with a supply line 2 for supplying a liquid to be inspected and a discharge line 3. Reference liquid supply means 6 is composed of an adding unit 6a and a plunger unit 6b. The number of particulates is read from a display unit 4. Then, a changeover switch 5 is changed over from a measuring mode to a cumulative mode and, at the same time, the measurement of a cumulative mode time is initiated. Thus, the number of the particulates instantaneously is displayed as zero. Then, since a prescribed quantity of a reference liquid is added to a liquid 10 to be inspected in a passage 9 from a disposal type injector cylinder 15 by turning a cock 11, the number of the particulates gradually increases and, after a peak value is reached finally, returns to the original value of the number of the particulates. A measurement is stopped at this time and changed over to the measuring mode again. The total sum of the numbers of the particulates in the cumulative mode obtained when the reference liquid is added thereto is obtained. When an obtained value matches a value obtained by a prescribed formula, the means 1 is judged to be normal.

摘要： PURPOSE:To automatically detect and judge the alteration of physical or chemical properties of an ion-exchange resin by installing a judging means to judge the abnormality of the ion-exchange resin when the difference between the reference height development flow speed at the time of back wash and the initial reference height development flow speed by comparison becomes larger than a previously set value. CONSTITUTION:In the case that ion-exchange resins 1A, 1B packed in an ion- exchange resin tower 1 are back washed by upward flow and developed, their reference height development flow speed becomes different from the initial reference height development flow speed if the physical or chemical properties of the ion-exchange resins 1A, 1B alter. Consequently, whether alteration of physical or chemical properties of the ion-exchange resins 1A, 1B occurs or not and the time to change or suppliment them can be known by measuring the reference height development flow speed of the ion-exchange resins 1A, 1B packed in the ion-exchange resin tower 1, obtaining the difference between the obtained speed and the initial reference height development flow speed, and comparing the difference with a previously set allowable value.

摘要： PURPOSE:To measure a fine-grain with high accuracy by measuring the fine-grain in a liquid to be measured by diluting the liquid to be measured, with superpure water. CONSTITUTION:At the time of starting measurement, a syringe is filled with a liquid to be measured, in advance, thereafter, a flow rate Q1 of superpure water by a pump 12, an injection quantity Q2 of the liquid to be measured, by a syringe pump 32, the time, and a name of the liquid to be measured are inputted to a computer body 44 from a keyboard 46, and a measurement start button 48 is pushed. As a result, by an operation of a switch 52, a solenoid valve 18 allows a pipeline 16 and 22 to communicate with each other. Subsequently, superpure water from a feed pipe 10 is brought to pressure rise by the pump 12, passes through an ultrafiltration device 14 and goes to super-high pure water which scarcely contains grains, mixed with the liquid to be measured, from a pipeline 26 by a mixer 24, and led into a fine-grain counter 40. Accordingly, since a sample liquid such as a chemical, etc. is dispersed into pure water, as for quantity of the sample liquid, a small quantity is enough, and also, since the measurement is executed under pressure, an air-bubble is dissolved and an error at the time of measurement is excluded, and the measurement is executed with high accuracy.

摘要： PURPOSE:To count the fine particles automatically and in a short time by counting the number of time particles image-picked up by an optical microscope to obtain the integrated number of these particles and then calculating the number of fine particles for each passed liquid quantity from said integrated number, the filter are and the quantity of liquid passed through a filter. CONSTITUTION:For such an optical microscope that has a focal point formed on the surface of a filter, the space (Z1) is obtained between the surface of the filter and an objective lens together with the space (Zn) between the filter surface and the objective lens where the focal point of the lens is distanct enough away from the filter surface and therefore the image pickup is impossible to the fine particle. The distance between spaces Z1 and Zn is divided equally into (n-1) sections. The areas of measurement of the filter surface are set on the intersecting points of a checker pattern. Therefore the 3-dimensional space coordinates including the areas of surface measurement and sections are obtained at each point. The fine particles of each section are measured at each area of surface measurement, and the number of fine particles are integrated over all sections. A count arithmetic part 32 measures the sizes and number of particles from the images of particles image-picked up by a TV camera 12. The results of counting of all sections of measurements are integrated. Then N (number of fine particles)=(total number of fine particles).S/(A.F) is calculted for each quantity of passed liquid from the quantity F of the liquid passed through the filter, the filter area S an the measurement area A.
