Abstract: The sample container has a two-layer membrane filter comprising a first layer as an upper layer serving as a hydrophilic membrane filter and a hydrophobic membrane filter as an underlying second layer capable of filtering an aqueous solution without the use of a wetting agent and by means of a formed negative pressure. Using this sample container, a large amount of an aqueous sample solution is filtered by means of a negative pressure formed by a suction portion to capture microbes in the aqueous sample solution by the hydrophilic membrane filter. Then, the negative pressure is restored to normal pressure, and a microbial dissolution solution is then added to the membrane filter to retain the microbial dissolution solution for a given time on the hydrophobic membrane filter. Then, the microbial dissolution solution is dispensed to a reaction container containing a luminescent reagent, and luminescence is detected to detect the microbes.

Abstract: There is provided means for analyzing organism-related molecules, dealing with multi item analysis, that are captured according to probe species, and for collecting according to the probe species. A magnetic micro-particle array is fixed with magnets that are configured with magnetic micro-particles in a capillary and with an array of glass beads to which DNA probes of different types from each other are immobilized. A syringe pump and a cross valve are operated to circulate a sample solution in the magnetic micro-particle array, which is reacted with probe DNAs on a glass bead with a probe. Subsequently, a washing solution is introduced to wash inside of the capillary. Next, respective beads are measured for fluorescence intensities. Furthermore a particular bead is collected based on results of fluorescence measurement. Target molecules captured on a surface of the collected bead may be separated by heat-denaturation, which then may be subjected to next analysis.

Abstract: In order to make a process of capturing and testing air-borne microorganisms more convenient and quick, a capturing device which comprises the capturing carrier comprising a polymer which is in a gel phase at the time of capturing the microorganisms but undergoes a phase transition under heating to a sol phase at the temperature at or less than 40° C. (especially in the temperature range between 15° C. and 37° C.), and a vessel to contain the capturing carrier is used. Further, by comprising a test reagent in the polymer, the test reagent can be eluted upon said phase transition from a gel phase to a sol phase. By heating the capturing carrier, a phase transition to a sol phase can occur at or less than 40° C. As such, since recovery of microorganisms and addition of a test reagent to the microorganisms can be carried out simultaneously, the process can be simplified and the process time can be shortened.

Abstract: In a parallel operational processing device having an operational processing unit arranged between memory blocks each having a plurality of memory cells arranged in rows and columns, the respective columns of each memory block are alternately connected to the operational processing units on the opposite sides of the memory block. By selecting one word line in one memory block, data can be transferred to two operational processing units. The number of the word lines selected per one operational processing unit is reduced, and power consumption is reduced. The bit operation units and sense amplifiers/write drivers of the operational processing units have arrangement pitch conditions mitigated and are reduced in number, and an isolation region between the memory blocks is not required and the layout area is reduced. Thus, the parallel operational processing device with a layout area and the power consumption reduced, can achieve a fast operation.

Abstract: A CAM (Content Addressable Memory) cell includes first and second data storage portions storing data, horizontal port write gates for storing data applied through a match line pair in the data storage portions in a data write through a horizontal port, and search/read gates for driving the match lines of the match line pair in accordance with the data stored in the data storage portions in a search operation and in a data read through the horizontal port. The match lines are used as horizontal bit line pair, or signal lines for accessing the horizontal port. As the first and second data storage portions are used, it becomes possible to store ternary data, and accordingly, a write mask function of inhibiting a data write at a destination of data transfer is realized. Further, as the CAM cell is used, an arithmetic/logic operation following a search process can be executed selectively, and high speed data writing/reading becomes possible.

Abstract: The present invention provides an apparatus for efficiently transporting or dispensing transport objects including not only particles but also liquid samples. A liquid in a first liquid transport pipe (3) is fed at a liquid feed velocity (V1), and a liquid droplet is formed toward an open end of a second liquid transport pipe (4) disposed with an air gap (11) in between. The particle is released into the liquid droplet, so that the particle is enclosed in the liquid droplet. Suction with a liquid feed velocity (V2) is applied to the inside of the second liquid transport pipe. Since the relationship between V1 and V2 is V1<V2, the liquid droplet, after reaching the open end (10) of the second liquid transport pipe, is sheared off by suction, thereby forming a liquid section in the second liquid transport pipe.

Abstract: Provided is a convenient process of manufacturing a two-dimensional bead array on a chip by disposing a plurality of beads immobilized with a biomolecular probe in a bead array container in a predetermined order. The bead array chip is manufactured by repeating the following operations: a container having a plurality of first channels disposed in parallel with each other and a second channel crossing therewith is retained in a container retaining portion and a capillary is moved through the second channel of the container vertically. The capillary is moved downward to suck and retain, in an end thereof, one bead stored in a storing portion of a bead storing plate and then, moved upward to the position of a desired first channel. Under this state, pure water is fed to the first passage from a water feed system and a water stream is generated by sucking the pure water by a suction pump.
