Abstract: With spreadsheet software, such as the MICROSOFT EXCEL, a radar chart can be compiled by the use of data in a table made.

Abstract: A program for displaying a radar chart which shows good visibility regardless of the number of items displayed. A degree of association between each axial label and at least one arranged keyword is judged on the basis of data indicative of the relationship between each axial label and the arranged keyword. The axial labels are assigned to a plurality of axes on a radar chart and a reference point for an assigned axial label is set on each of the plurality of axes. A display position for the arranged keyword is set at a location nearer to a reference point for an axial label the degree of association of which with the arranged keyword is relatively high than to a reference point for an axial label the degree of association of which with the arranged keyword is relatively low. Then an image indicative of the arranged keyword is displayed at the display position set on the radar chart.

Abstract: According to a display processing unit, dividing axes are arranged and the division number and a connection between classification results are simultaneously displayed by a polygonal line onto a parallel coordinate graph obtained as a polygonal line by plotting a classification result of every plural analysis items by a clustering processing unit onto an axis of each analysis item. An annual ring diagram showing a division number which is more proper as an annual ring is thicker is displayed. The display processing unit displays a tree diagram obtained as a processing result of a classification processing unit by a folding, sorting, or the like so as to be easily understood. An output processing unit converts an unknown rule discovered by the classification into a format which can be used in an external application and outputs it.

Abstract: A method for purifying water containing organic matter includes dispersing photo-catalyst particles and an inorganic coagulant into the water; oxidizing the organic matter by activating the photo-catalyst particles by irradiating them with light; maintaining the diameter of the photo-catalyst particles to be equal to or less than 0.1 mm; and condensing the photo-catalyst particles and the inorganic coagulant.

Abstract: A purification apparatus and method for enabling the purification of the lake and pond waters, is installed as a fluidized bed sewage system directly on the raw water area. The apparatus takes in the raw waters in the lake and pond and purifies the water. The purified water is fed back to the raw water area by the pump.With this purification apparatus, the salt materials such as phosphate in the lakes, and the overall area of the waters can be purified while preventing the generation of phytoplanktons.

Abstract: In a fluidized bed filtering apparatus, for preventing particles of filtering material from entering into a feed pipe to clog the feed pipe and lowering the frequency of washing operations, a filtering material layer made of granular filtering material is supported by a supporting layer disposed in a filtering chamber so as to provide a space in the lower portion of the filtering chamber and two lines of a first feed pipe the outlet of which opens in the filtering material layer and a second feed pipe the outlet of which opens within the space are provided for feeding corrupt water into the filtering chamber.

Abstract: A magnetic separation apparatus which coagulates substances to be removed in liquid by adding magnetic substances and a flocculent to liquid to be treated and adsorbs and captures the thus obtained magnetic aggregates by utilizing magnetic field of magnetic substances which move relative to the liquid to be treated, and other magnetic separation apparatus comprising a magnetic filter which contains charging magnetic metallic elements placed in a magnetic field and which magnetically adsorbs and captures the magnetic aggregates, are appropriately combined to remove the magnetic aggregates from the liquid to be treated with good efficiency. Substances to be removed in liquid can be removed with further good efficiency by employing a method of separating the magnetic aggregates separated by the magnetic filter from liquid with a centrifugal separator.

Abstract: A purification system is provided for purifying the water of eutrophic lakes and marshes by partitioning the target lake/marsh to form a specified water treating area therein. For this purpose, a partitioning structure is provided for enclosing and partitioning the whole or part of an area around the mouth of each river flowing into the target eutrophic lake/marsh in the direction of depth to form a water treating water area; and a purifier for taking in water from the water treating area operates to separate and remove pollutants from the water, and then discharges treated water outside the water treating area.

Abstract: A chemical analyzer has turn tables respectively carrying reaction vessels, sample containers and reagent containers disposed thereon in circular rows. A sample pipetting mechanism and a reagent pipetting mechanism are provided to transfer predetermined amounts of sample and reagent solution from a sample container and from a reagent container into a reaction vessel. The thus transferred sample and reagent solution are mixed in the reaction vessel by a stirrer comprising a piezoelectric element which is disposed in non-contacting relationship to the sample and reagent solution in the reaction vessel and is electrically energized to generate a sound wave which causes a circulating flow of the reagent solution in the reaction vessel whereby the sample and the reagent solution are mixed in a non-invasive manner.
