Abstract: PURPOSE:To increase a treatment speed by random accessing by providing a plurality of reaction lines holding a plurality or reaction tubes to feed the same intermittently and setting said lines to independent reaction lines with respect to items different in a reaction time. CONSTITUTION:A reaction tube supply apparatus 6 supplies reaction tubes 4 of an indicated item to the reaction tube holders of reaction lines 2a, 2b and a specimen distribution apparatus 8 distributes a specimen in each of the reaction tubes and a reagent distribution apparatus 10 distributes a diluent and an enzyme labelled solution. Antigen-antibody reactions are respectively performed in the lines 2a, 2b for the time until reaching a washing apparatus 12 and the reaction tubes 4 are washed by the washing apparatus 12 and a color forming solution distribution apparatus 14 distributes a color forming solution and color forming reaction due to enzyme is performed for the time until absorbance or fluorescence is measured by a colorimeter 16 and a residual solution discharging/reaction tube disposing apparatus 18 discharges a residual solution and excludes the reaction tubes 4. As mentioned above, when a common treatment operation part is allowed to act on a plurality of the reaction lines different in a reaction time in a time sharing manner, the increase of a treatment speed and cost reduction can be achieved.

Abstract: PURPOSE:To make the random access of analytical items largely different in their reaction times possible by providing small washing groups separate from a main recirculation group. CONSTITUTION:The different reaction times due to analytical items are adjusted by differentiating the recirculation number of times through a recirculation loop 2. Respective functional parts of a reaction tube removing part 6, an new reaction tube setting part 8, respective distribution parts 10, 12, 14, 16 of beads, a dilution liquid, a sample and a specimen and an absorbancy measuring part 18 are provided and, according to a built-in program, the treatment of each reaction tube 4 at the time of passage is individually selected to perform random accessing. A washing part 24 functions over continuous several steps simultaneously and arranged along a small loop 20 separate from the loop 2 and the reaction tube 4 required in washing is transferred to the loop 20 from the branch part 22a of the loop 2 and washed in the washing part 24 to be returned to the original position of the loop 2 at a confluent point 22b. By this method, in one reaction, the loop 2 is used so as to make one or more round and, in chemical analysis of a 1, 2 step method of two or three reactions and simple one reaction, one of respective function parts can be adapted.

Abstract: PURPOSE:To set a sample conveyance quantity equally to the content of a cell and to use a sample effectively by detecting a break of sample liquid in a feeding flow passage in front of the flow cell and removing entering air bubbles. CONSTITUTION:A liquid feeding means 2 feeds the sample liquid 4 to the flow passage (a) by 0.4ml in 0.8 second from the start of feeding. Then a liquid feeding means control part 6 switches the speed of the means 2 and operates an air bubble detecting means 5. The sample liquid is fed by 0.1ml in one second from the switching. Then when the means 5 detects an air layer due to a liquid break, the means 2 is stopped according to the detection output and the means 2 is driven reversely. This reverse driving is carried out until the liquid 4 is fed backward in the flow passage (a) and the air-layer detection signal from the means 5 is ceased. Consequently, the air layer entered into the flow cell 3 is discharged from the cell 3, which is filled with the liquid 4.

CONSTITUTION:The light diffracted with the concave diffraction grating G of a spectroscope 1 is imaged on a photodiode array P driven by a sweeping circuit 2 and the output thereof is inputted and stored in a control circuit 3 via a preamplifier 4 and an ADC5. The photometric value thereof is segmented to plural numbers of partial wavelength regions and the ratios of the max. value of the measured values in the respective partial region to the satd. output value of the photodetectors P are calculated and the scanning speed of the circuit 2 is controlled until the ratios thereof attain 1. In this state, the transmittance is measured, whereby the SN ratio is improved.

Abstract: PURPOSE:To continue the measurement smoothly and to elongate the life of light sources by turning ON one or both of light sources depending on whether both ends of the wavelength region to be measurd are included in one of the two light sources having different wavelengths or in both light sources. CONSTITUTION:The position of a light path switching mirror C is controlled by a switching mirror driving device 4. One of the light paths from the light source of a deuteium lamp D2 having a short wavelength region and the light source of a tunstem lamp having a long wavelength region is sent to a slit S via a condenser mirror M. To a lambdamax setting register Lmx, a lambdamin setting register Lmi, and a lambdach setting register Lch, the data of the long wavelength end, the short wavelength end, and the light source switch wavelength in the wavelength region to be measured are inputted by a ten key T and an input device I. A wavelength scanning and driving part 1 and a judging part J are driven by control device 3. Thus the switching mirror driving part 4 is controlled depending on whether one of the lamps D2 and W is used or both are used, and the light path switching mirror C is stoppe at a position C1 or C2m or the mirror C is reciprocated in synchronization with the measurement. Therefore the intermittent flashing of the light can be eliminated, the lift of the lamps is elongated, and the stable and continuous measurement can be performed.

Abstract: PURPOSE:To compensate fluctuation of the light source without including the error due to the difference of average reflection factor in the integral sphere and without requiring the same standard materials, by using a part of the inside face of the integral sphere itself in stead of standard materials. CONSTITUTION:The light from light source L is inputted to integral sphere I through light incident window In, and lights emitted from emitting window Ou, which is in the position opposite to sample (s), and emitting window Ou', which is in the position opposite to a point off from sample (s), are incident to spectroscope M through rotary chopper Y of three blades, semitransparent mirror H, and mirror X. The light emitted from spectroscope M is inputted to signal processing circuit Z through photodetector D and preamplifier A. Switches SW1 and SW2 are switched while interlocking with chopper Y, and outputs corresponding to light fluxes Fs and Fst are held in capacitors K1 and K2. The output of capacitor K1 is stored in memory Me through the A-D converter, and the output of capacitor K2 is fed back to photodetector D through boosting DC-DC converter D-D. As a result, the influence of fluctuation of the light source is prevented.

Abstract: PROBLEM TO BE SOLVED: To provide a vacuum pump which enables a precise detection of a rotor temperature even when a gap between a magnetic body for temperature detection and a detection coil changes.
SOLUTION: A detection signal related to the magnetic body 102 is normalized and compensated by a difference signal between a lower side signal related to a notch 103 and an upper side signal related to the magnetic body 104, and the normalized and compensated signal (S-L)/(H-L) is compared with a threshold level to judge whether the rotor temperature exceeds the Curie temperature of the magnetic body 102. The use of the normalized and compensated signal is possible to make the signal change before and after the Curie temperature be almost the same independent of the gap dimension, and the temperature can be accurately judged without being affected by the gap change.
