A chemical analyzer for measuring a concentration of components of a sample liquid, by mixing the sample liquid with reagents, so as to react the reagents upon the components thereof. The chemical analyzer includes a carrier which is constructed on a substrate and has an introducing portion through which the sample liquid is injected, distributing flow passages for distributing the sample liquid injected from the introducing portion, and plural reactor portions, each holding the sample liquid therein to be mixed with the reagent, thereby to react. A movable driver portion is provided for mounting the carrier thereon, and a reagent charging device is provided for ejecting the reagents, which are different for the respective reactor portions of the carrier. Further, a detector is provided for detecting the components after mixing the reagents with the sample liquid.

A chemically analyzing apparatus includes a plurality of reaction containers, a reaction container holder for holding the plurality of reaction containers and for supplying a sample and reagent at predetermined positions, a plurality of reagent containers for holding reagent adapted to be supplied into the reaction containers, a reagent container holder provided above the reaction container holder, for holding the plurality of reagent containers, a measuring part for measuring physical properties of the sample, a liquid feed mechanism provided in a lower part of each of the plurality of reagent containers, for supplying a predetermined quantity of reagent from each of the reagent container into the associated reaction containers by means of the liquid feed mechanism. With this arrangement, it is possible to provide a chemically analyzing apparatus incorporating a reagent supply mechanism which can prevent reagent from being uselessly consumed, which does not substantially require washing liquid, which does not require periodical disassembly and washing, and which can easily change the feed quantity of reagent.

A device for cell culture capable of automatically performing operations for cell culture over several days to several months while minimizing the risk of contamination. A new medicine can be supplied to an incubator means by using a medicine supply means or unnecessary wastewater can be discharged from the incubator means by using a wastewater discharge means without taking out the incubator means disposed in heat insulation box means from a heat insulation box, and the state of the cell culture can be observed with the incubator means formed in the heat insulation box means. Accordingly, the outside air does not enter directly into the incubator means during culturing, and the risk of contamination is completely eliminated. As a result, the culturing operations can be automatically performed over a long period.

A small reactor with high heat-release performance is provided. A reactor 1 includes an assembly (10) and a case (4), the assembly (10) having a coil (2) and a magnetic core (3) at which the coil (2) is arranged, the case (4) housing the assembly (10). The case (4) includes a bottom plate (40) that contacts a fixing object when the reactor (1) is installed on the fixing object, a side wall (41) that is mounted on the bottom plate (40) with an adhesive and surrounds the assembly (10), and a junction layer (42) that fixes the coil (2) to an inner surface of the bottom plate (40). The bottom plate (40) is formed of a material with higher thermal conductivity than that of the side wall (41). The reactor (1) easily transfers heat of the coil (2) to the bottom plate (40) and hence has high heat-release performance because the reactor (1) includes the bottom plate (40) with the high thermal conductivity and the coil (2) is joined to the bottom plate (40) through the junction layer (42). Since the bottom plate (40) and the side wall (41) are integrated using the adhesive, the thicknesses of both the members (40, 41) can be decreased. Accordingly, the reactor (1) is small.

A motorcycle design that easily secures space for exchanging tires. A unit-swing type, rear wheel driving power unit is disposed on one side of a rear wheel in a transverse direction and has a swing fulcrum in front of a rear wheel axle, and a right and left pair of rear suspension units are disposed on right and left sides of the rear wheel. An installation height of the rear suspension unit on an opposite power unit side is higher than an installation height of the rear suspension unit on a power unit side, and an installation position of the rear suspension unit on the opposite power unit side in a width direction of the vehicle body relative to the rear wheel is more inside than an installation position of the rear suspension unit on the power unit side in the width direction of the vehicle body relative to the rear wheel.
摘要:
Microcapsule-reagents are prepared by previously reacting at least a part of an antigen or antibody attached to microcapsules encapsulating a labeling substance with an antibody or antigen which is specifically reactive therewith, and then the reagent thus prepared is reacted with a sample containing an antigen or antibody in the presence of a complement, whereby highly sensitive immunoassay of the antigen or antibody in the sample can be realized even when the antigen or antibody attached to the microcapsules has a lowered activity or has only low reactivity with the antibody or antigen in the sample.
摘要:
A method for immunoassay for an antigen involves the following steps: reacting a sample possibly containing an antigen to be determined, a definite amount of a conjugate of the antigen and a charged substance and a definite amount of labeled antibody specific for antigen; allowing the reaction products to electrophoretically migrate towards a carrier bearing an attached antibody specific for the charged substance, so that when the reaction products contact the carrier any reaction product of labeled antibody and antigen passes through the carrier and any reaction product of the labeled antibody and conjugate binds to the carrier attached antibody specific for the charged substance; determining the amount of labeled antibody thereby bound to the carrier and relating the determined amount of labeled antibody to the amount of antigen in the sample.
摘要:
A digital display device for forming one or more electro-transmissive display patterns, which comprises a pair of oppositely disposed electrodes to which a signal is supplied for energization. Each of the electrodes includes a number of electro-conductive sections which are disposed with a lower distribution density at the central portion and with a higher distribution density at the contour portion. This mode of distribution of the sections gives an equivalent visual contrast to the situations in which all the sections are disposed with a uniform distribution while at the same time reducing the power consumption rate.
