    Abstract: PURPOSE:To make possible the measurement of transmitted light with high accuracy even with a sample of an optional shape with which the luminous flux after the transmission thereof diverges, shifts or deflects or a sample having a light scattering characteristic by making exchangeable a reference light signal and sample light signal in a photometric circuit. CONSTITUTION:The photometric output of the luminous flux R is inputted from a switch Sw via a contact 1 to a comparator C in the case of connecting a manual change-over switch SC to the arrow shown by a solid line. The output is then compared with a reference level in a comparator C and the difference between both is inputted to a high-voltage generating circuit H. The high-voltage outputted from the H is fed back to a photodetector P and the sensitivity of the photodetector P is so controlled that the photometric signal of the flux R is made constant. On the other hand, the photometric output of the flux S is inputted from the switch Sw via a contact 2 to a signal processing circuit N. The sensitivity of the photodetector P is so controlled that the photometric output of the flux S is this time made constant when the switch SC is changed over to the connection state shown by a dotted line. The photometric output of the flux R is then inputted to the circuit N.

    Abstract: PURPOSE:To perform two reflection measurements without changing the positions of a light source and a light detector, by providing four windows in the same plane including an optical axis in an integrating sphere, with one window as a light inputting window, another window as a light emitting window, and the remaining two windows as sample windows. CONSTITUTION:In an integrating sphere, four windows Wi, Wo, Ws1, and Ws2 are provided. In the case of Ro/d measurement, a sample S is placed at the window Ws1 facing the light inputting window Wi. A white plate Sw is placed on the other sample window Ws2. Then, the light, which is inputted from the light inputting window Wi, is directly inputted to the sample S in the vertical direction. The component of the light reflected by the mirror surface of the sample S is emitted out of the integrating sphere through the light inputting window Wi. Only the diffused component of the reflected light repeats the reflection in the integrating sphere and is inputted to a light detector D through the light emitting window Wo. In the case of Rd/o measurement, the white plate Sw is placed at the sample window Ws1, and the sample S is paced at the sample window Ws2 facing the light emitting window Wo.

    Abstract: PURPOSE:To widen a sample chamber and to reduce the distance between the sample and a photodetector by so arranging a titled meter that divided two luminous fluxes are intersected again at around 90 deg. angle and disposing one photodetector commonly for the two luminous fluxes near the point of intersection thereof. CONSTITUTION:The luminous flux emitted from a spectroscope is divided and the divided luminous fluxes are intersected again at around 90 deg.. One photodetector is disposed commonly for the two luminous fluxes near the point where the two luminous fluxes intersect. For example, the light out from a spectroscope M is divided to two luminous fluxes with a sector mirror S1; the reflected luminous flux is reflected by mirrors m3, m4, and the transmitted luminous flux is reflected by mirrors m1, m2. These two luminous fluxes are intersected orthogonally on the photodetection surface of a photomultiplier P. Further, two sheets of light diffusion plates D, D' are disposed orthogonally in front of the photodetection surface of the photomultiplier P so as to assure the equivalency of the two luminous fluxes.

    Abstract: PURPOSE:To detect fluorescence surely by subtracting fluorescence intensity from the apparent reflected light intensity in the wavelength of lighting light of reflected light spectra and calculating a spectral reflected radiance factor and a spectral fluorescence radiance factor. CONSTITUTION:The device consits of a lighting spectroscope M1 and a reflection spectroscope M2. In the spectroscope M2, a multichannel photometric element D is disposed along the spectral image plane, and the operation of interpolating the fluorescence intensity at the wavelength of lighting light from the reflected light spectra of a sample Sm is accomplished at every wavelength in the wavelength scanning of the spectroscope M1. The interpolated fluorescence intensity is subtracted from the apparent reflected light intensity at the lighting light wavelength of the reflected light spectra in an arithmetic circuit. The fluorescence intensity is divided by the ratio of the wavelength width of the spectroscope M2 to the wave- length width of the spectroscope M1. An arithmetic circuit calculating a spectral reflection radiance factor and a spectral fluorescence radiance factor from these two is provided.

    Abstract: PURPOSE:To enable employment of biface ground cell by conducting irradiation and incidence of an excitation light and a measurement light to a sample cell from one direction through the same light path. CONSTITUTION:When the light path is closed by choppers CH1 and CH2, a monochromatic exitation light flux having a fixed wavelength, shown by dotted lines, is reflected by the chopper CH1, irradiates a sample S from the front of the sample cell C1, is transmitted therethrough, promoting the photochemical reaction, and is reflected by the chopper CH2 and caught and absorbed by a trap Tr1 via reflecting mirror M2. When the light path is opened by the choppers CH1 and CH2 simultaneously, the monochromatic excitation light having the fixed wavelength is caught and absorbed by a trap Tr2 via reflecting mirror M3. On the other hand, a monochromatic measurement light flux having a specified wavelength, shown by a solid line, passed through the same light path, is made incident in the sample S from the front of the sample cell C1, transmitted therethrough, caught by a detector D, transduced into an absorptivity signal by a signal processing circuit, and thus the photochemical reaction of the sample S at that point of time is measured.

    Abstract: PROBLEM TO BE SOLVED: To improve maintainability by highly accurately monitoring effective chlorine concentration in generated strongly acidic water even by intermittent measurements and extending the life of the monitoring apparatus by this. SOLUTION: When a predetermined time has elapsed, the operation of shear pumps 24 and 25 are restarted to start the operation of sucking strongly acidic water and strongly alkaline water generated by a strongly electrolytic water generator 11 and feeding them to a liquid tank 28 for mixing. After 15 minutes when the operation of the pumps 24 and 25 are stabilized, only the liquids fed by the pumps 24 and 25 in which the quantity of flow is stabilized remain in the liquid chamber 28 of an overflow chamber to stabilize its mixture ratio. Since effective chlorine concentration is measured through the use of the output of a spectroscope assembly 34 at this time, it is possible to highly accurately monitor the effective chlorine concentration even by intermittent measurements and extend the lives of the pumps 24-27 by this.

    Abstract: PROBLEM TO BE SOLVED: To provide an apparatus for producing electrolytic water in which concentration monitoring based on spectrophotometry can be achieved without influencing a measured result even when the output characteristics of a light source changes with long-time use.
    SOLUTION: The electrolytic water sampled from the intake of an electrolysis vessel 11 is mixed and agitated by a second water tank 67 via a first water tank 61, and sent to the flow cell 31 of a measuring part 30a. Light from a light source 32 passes through an optical filter 34a, is selected as 292 nm wavelength and is reflected in part by a beamsplitter 33. Reflected light is used as control luminous flux, and light passing through the beamsplitter 33 passes through the sample of the flow cell 31 and is used as sample luminous flux. Signals from each photocell 36 and 37a are received by a data processing part 38a, corrected on the basis of the difference between the signals to detect absorbancy, and effective chlorine concentration is displayed on an output part 39.
