摘要： Fluorescent dye is added (20) to a sample including lymphatic cells stimulated by antic bodies to measure fluorescence polarization. The fluorescence polarization varies with time. The measurement is stopped after a predetermined measurement time, and the lymphatic cells are separated from the sample by filtering (30). In order to determine the fluorescence polarization in a filtering process, approximate equations of the reaction are determined (40) based on the fluorescence polarization measured during the reaction process. Based on the approximate equations I 1 (t), 1 2 (t), the fluorescence polarization in the filtering process is calculated. The reaction process is approximated by both an approximate linear line (A, F, G) and an approximate curve (B, C, E, H). A reaction data at a predetermined future time is calculated based on the two approximate functions so that a reliability of the resulting data is improved.

摘要： A light signal entering a photo-electric converter means is interrupted at a certain interval of time. An electrical signal produced from the photo-electric converter means, after a predetermined amount of electrical signal is added to it, is A-D converted. The difference between the digital signal associated with the interruption of light to the photo-electric converter means and the digital signal associated with non-interruption of light to the photo-electric converter means is produced, which difference is proportional to the incident light signal. Even when the light entering the photo-electric converter means is very weak, the fact that a predetermined amount of electrical signal is added contributes to A-D conversion of good linearity. Even very weak light is thus A-D converted accurately. Noises and undesirable DC signal components contained in the two types of digital signals are offset by production of the difference.

摘要： PURPOSE:To facilitate the adjustment of a measuring apparatus and to improve the adjustment efficiency by converting a result of measurement to an audible sound and expressing it, and informing the result of measurement by a sound wave to an operator who is executing the adjustment. CONSTITUTION:In a microspectrophotometer, the signal quantity detected by a detecting means 5 is converted to a proportional electric signal, amplified 6, A/D-converted 7, and thereafter, inputted to a digital computer 8. A result of measurement of a spectral reflection spectrum, etc., is displayed on a measurement result indicator 9. IN such a state, at the time of adjustment of an apparatus, a voltage output being proportion to the signal quantity detected by the detecting means is outputted from a computer 8 through a D/A converter 10. This output is frequency-converted 11 and amplified 12 and a sound wave is generated from a loudspeaker 13. A pitch of a generated sound wave corresponds to magnitude of the signal quantity detected by the detecting means 5, therefore, an operator can concentrate on the adjustment work by depending on a pitch of a sound from the loudspeaker 13 without looking at the measurement result indicator 9.

摘要： PURPOSE:To execute a wavelength calibration and setting of initial values in a short time by a simple constitution, by deriving a signal for detecting whether a tuning wavelength of a spectroscope is in a longer wavelength side or a shorter wavelength side than a calibrating wavelength. CONSTITUTION:When a tuning wavelength lambda of a tuner of a spectroscope is in a longer wavelength side than a calibrating wavelength lambdaC, by a wavelength position discriminating plate 30, a wavelength position discriminating signal 60 from a lightning photoelectric converting means 20 becomes a long wavelength detecting signal, and when the tuning wavelength lambda is in a shorter wavelength side than the calibrating wavelength lambdaC, the wavelength position discriminating signal 60 becomes a short wavelength detecting signal. When a power source is turned on, the spectroscope is scanned automatically in the direction of the calibrating wavelength lambdaC by said detecting signal, and when the tuning wavelength of the spectroscope has become the calibrating wavelength lambdaC, a value of lambdaC is set to a wavelength is set to a wavelength counter and a wavelength scan is stopped, by a wavelength calibrating pulse generated by a variation of said detecting signal.

摘要： PURPOSE:To make the restoration possible without direct manual operation, by selectively forbidding only the driving in the short wavelength direction by a short wavelength end limit switch and only the driving in the long wavelength direction by a long wavelength end limit switch. CONSTITUTION:When the short wavelength limit switch 42 is turned ON, an AND gate 46A is cut OFF and forward direction pulses FWD are forbiddin, but reverse direction pulses REV can be supplied to a sequence circuit 31 through an AND gate 46B. Conversely, when the long wavelength limit switch 43 is actuated and turned ON, the AND gate 46B is cut OFF and the reverse direction pulses REV are forbidden, but the forward direction pulses FWD can be supplied through the AND gate 46A. In any case, the switches 42 and 43 are never turned ON simultaneously. In this constitution, even though the driving is stopped at the end of either wavelength, the restoration can be always achieved by the driving in the reverse direction.

摘要： PURPOSE:To eliminate the replacement of filters by arranging them on individual image detectors adapted to simultaneously detect spectra scattered according to the wavelength, as shited perpendicular to the scattered surface. CONSTITUTION:A light coming from a slit 21 is separated into spectra lambdal...lambdan with a grating and a prism. They irradiate image detectors 3, the output of which is processed with an amplifier 4, a scanner 5, an A/D converter 7, a memory 8 and the like to obtain data. The image detector 3 is composed of a plurality of detectors 31-33 and shifted perpendicular to the spectral surface (at the right angle to AA'' in the drawing) and with both ends overlapping, cut filters 36-38 are inserted into the front of the photo detection surface of the detectors as required. This enables simultaneous measurement of multiple wavelength elminating complicated replacement of the filters thereby providing a spectrometer minimizing the mixing of stray light and light of higher order.

摘要： PURPOSE:To cancel the difference in the quantity of light due to difference in the reflecting parts of a rotary flicker device in a signal processing system, by integer- multiple-integrating the detected signals of sample light and reference light respectively in response to the number of reflecting members of the rotary flicker device. CONSTITUTION:A monochromatic light from a slit 3 of a spectroscope is reflected by the reflecting part of a rotary flicker device 10 to become a reference light and, simultaneously, become a sample light by transmitting through the sample provided in the transmission part, and the both lights are alternately detected by a detector 6 through a similar flicker device 10' which turns in synchronism with the flicker device 10. The both detection outputs of this detector 6 are passed through an A/D converter 30 and a memory 31 to be integrated by the integer multiples in a digital operation unit, depending on the number of the reflecting parts in the flicker devices 10, 10' thereby becoming a detection output with the difference in the quantity of light due to difference of reflecting parts canceled each other. Therefore, spectral analysis is possible without being influenced by the difference of the reflecting parts in the flicker devices.
