    Abstract: PURPOSE:To make it possible to discolor a material in an arbitrarily specified pH range with porphylin having a high mol extinction coefficient as a pH indicator, by supporting and fixing hydrophobic porphylin with water-insoluble macromolecules, and the like. CONSTITUTION:Hydrophobic porphylin is supported and fixed with water- insoluble macromolecules. Or the hydrophobic porphylin and an organic material having positive or negative electric charge are supported and fixed with the water-insoluble macromolecules together. Thus a pH sensitive solid-state material is obtained. As the method for manufacturing the pH sensitive thin film, the water-insoluble macromolecules are dissolved into a solvent such as tetrahydrofuran. This material and porphylin are added. The organic material having the positive or negative charge is further added as required. Thereafter, this is developed on a transparent resin plate, a glass plate or the surface of water. This method is simple. Thus, a very thin film is obtained. In this way, discoloration can be performed in an arbitrarily specified pH range, with porphylin having a high mol extinction coefficient as a pH indicator.

    Abstract: PURPOSE:To set the numerical value to a counter easily and quickly through simple constitution by supplying control pulses to plural count stages in response to the revolving speed of a rotor. CONSTITUTION:When a rotor pulse generator 11 is rotated, the control pulses P are supplied to a setting count stage 131 for low-order digits, a revolving speed detecting means 16 and a pulse generator 17 respectively from the means 11. The generator 17 sends a control pulse having the same frequency as that of the pulse P to an OR circuit 18 based on the permission signal given from the means 16 when the revolving speed of the means 11 exceeds a prescribed level. Then the control pulse is sent to a setting count stage 132 for high-order digits from the circuit 18 without waiting for a carry signal 131C sent from the stage 131. Thus it is possible to set quickly the numerical value to each count stage.

    Abstract: PURPOSE:To enhance washing effect, by flowing a part of the next liquid to be examined through a flow cell prior to measurement while repeating flowing and stopping. CONSTITUTION:A flow cell consists of a flow cell main body 1, an indication electrode 2, a comparison electrode 3, a pipeline 4 for introducing a liquid to be examined, the liquid 5 to be examined and a pump 6. A part of the next liquid to be examined is sucked from the left side of the pipeline 4 prior to measurement by the pump 6 to be introduced into said pipeline 4 and the starting and stopping of the pump 6 is repeatedly performed regularly. The preceedingly measured liquid adhered to the interior of the flow cell main body 1 or the detection terminal parts of the electrodes 2, 3 is perfectly removed and discharged by the pump 6.

    Abstract: PURPOSE:To improve a washing effect and to make a quick and highly effective measurement of organic contamination turbidity possible, by carrying out automatic washing and manual washing by jetting air in a passing hole of a liquid to be inspected or inserting a freely detachable manual brush. CONSTITUTION:When an air pump 24 is started, air bubbles are jetted from an opening 27 of the lower part of a measurement cell 5 and a compensation cell 6 of a detection part for measurement 4 and contaminants stuck to the cells 5, 6 are washed automatically. Next, when the pump 4 is stopped and an air pump 25 is started, the bubbles are jetted from an opening 29 of the upper part of the cell 5, 6 and pressure difference is brought out between the upper and lower sides of the cells 5, 6. Then, circulation of a liquid to be inspected is accelerated and the degree of contamination turbidity of the liquid to be inspected is measured in accordance with the absorption rate of ultrviolet rays etc. On one hand, when manually operating brushes 31, 30 are inserted into each cell 5, 6 through a movable pipe, the cells 5, 6 are washed manually. The degree of organic contamination turbidity is measured quickly and highly effectively by impreving the washing effect by using jointly the automatic washing and manual washing.

    Abstract: PURPOSE:To prevent blocking of a liquid junction, by a method wherein, after an electrode lead-in wire covered with an insulating material is inserted into inner liquid through one end of an outer tube, the insulating material at the end part of the electrode lead-in wire in the inner liquid is unsheathed for exposure, the exposed part is surrounded with an ion selective hardening material. CONSTITUTION:A liquid junction 6 is formed in an outer tube 1 which is filled with conductive inner liquid 8, and after an electrode lead-in wire 4 covered with an insulating material is inserted into the inner liquid 8 through the one end of the outer tube 1, the insulating material at the one end of the electrode lead-in wire 4 in the inner liquid 8 is unsheathed for exposure. The exposed part is water tightly surrounded with an ion selective hardening material 13 in which gel by dibenzal sorbitol of ion exchange liquid or a derivative thereof is evenly dispersed and held in an epoxy resin hardening material consisting of 5-50 pts.wt. epoxy resin hardening material consisting 5-50 pts.wt. epoxy resin containing a hardener, 5-25 pts.wt. dibenzal sorbitol or a derivative thereof, and remaining pts.wt. ion exchange liquid.

    Abstract: The method of the present invention comprises the steps of irradiating near-infrated rays to a plastics of an unknown type to measure the NIR spectrum thereof, determining the first-derivative or second-derivative, measuring the differential spectrum at prescribed intervals of wavelength over a region of measurement wavelengths, determining the class of whether the differential spectrum for each measurement wavelength is on the plus-side, minus-side or any other side, comparing the resultant class data with those of previously determined differential spectra for plastics of known types to determine the ratio of agreement between the thus compared data (agreement ratio), and determining that the plastics showing the highest agreement ratio is the type of the plastics of the unknown type. By using the above-mentioned agreement ratio, it is possible to simply and rapidly determine the type of a plastics by means of the differential spectrum of near-infrared rays.
