摘要： PROBLEM TO BE SOLVED: To provide an aquarium for subculture, keeping adult fish, young fish and eggs in the raising aquarium 20, and enabling the adult fish, the young fish and the eggs to be raised by correcting the flow of raising water to the adult fish, the young fish and the eggs. SOLUTION: The closed raising aquarium is separated to a raising chamber 1 and an egg-gathering chamber 3, and is in a type of separating the eggs from the raising chamber 1 in which the adult fish are present to the egg- gathering chamber 3 by controlling the flow of the raising water from the raising chamber 1 to the egg-gathering chamber 3. A movable mesh 7 for the adult fish which allows the young fish to pass but does not allow the adult fish to pass is installed in the raising chamber 1, and the size of the space for raising the adult fish and that of the space for raising the young fish are constituted so as to be controllable by the dislocation of the movable mesh 7 for the adult fish.

摘要： PURPOSE:To obtain necessary information, e.g. the time when a cell arrives at a detector, while allowing indirect detection of the cell using absorptiometry by causing electrophoresis of the cell along with an easily detectable standard sample. CONSTITUTION:A capillary tube 1 is filled with a cell and a detecting marker. The tube 1 is partially wound around a cylindrical rod 4 having an appropriate diameter. An electrophoretic bath 3 is provided, on the bottom thereof, with a window 5 for detecting a cell arriving thereat. The electrophoretic bath 3 is coupled, at its lower part, with tubes 6 for sampling the cell and buffer liquid passed through the detection window 5 and the tubes 6 are coupled, at the other ends, with a peristaltic or a syringe type pump. When electrophoresis is conducted, a butter liquid suspending the cells is admixed with the detection marker (an easily detectable standard sample) and injected into the bath 3. A high concentration serum protein which does not interact with the cell is employed, for example, as the detection marker.

摘要： PROBLEM TO BE SOLVED: To enable aquatic organisms and articles to be taken into and out of an aquarium while suppressing the outflow of raising water and keeping the liquid surface in the aquarium in a structure for taking out the small aquatic organisms from the closed aquarium for raising the aquatic organisms. SOLUTION: A liquid surface-keeping tool 13 obtained by overlapping two sheets of a rubber or a resin having radial cuts 16 and 17 respectively so that the cut positions are different is attached to an access port 2 of the closed system aquarium 12. An organism-capturing tool 1 is attached to the access port 2, and in the state, the liquid surface-keeping tool 13 having the cuts 16 and 17 are opened. The organisms-capturing tool 1 has a piston 5 having a sponge 7 attached to the tip, and a cylinder 4, and captures the aquatic organisms in the cylinder 4 in a state in which the sponge 7 is drawn into the cylinder 4.

摘要： PURPOSE:To enable stable operation even with a device having a thick vessel by using, as migration buffer solution, organic anion electrolytic solution whose pKa value is 6 to 9 and equivalent conductivity is 30Scm /mol or less neutralized by organic strong base electrolyte whose pKa value is 13 or larger and equivalent conductivity is 40Scm /mol or less. CONSTITUTION:Organic anion electrolyte to be used as buffer solution whose pKa value is 6 to 9 and equivalent conductivity is 30Scm /mol or less is sulfonic acid derivative, for example. The pKa value of this electrolyte is specified to 6 to 9 because a living specimen cannot be alive if pKa is less than 6 or higher than 9. The equivalent conductivity of organic anion electrolyte is specified to 30Scm /mol or less because the lower the equivalent conductivity, the more desirable. Ammonium is selected as an example of electrolytic materials which satisfies the above conditions. The pKa value is specified to 13 or larger because the amount required for neutralization increases if the pKa value is less than 13, and the conductivity is specified to 40Scm /mol or less because the lower the conductivity, the more preferable.

摘要： PURPOSE:To balance the inflow and outflow of ions between electrode chambers and electrophoretic space and to suppress the rise of the electrical conductivity of a buffer soln. by spreading an electrode membrane obtd. by vertically joining an upper cation membrane and a lower anion membrane at the anode side of a free flow type electrophoretic apparatus and an electrode membrane obtd. by vertically joining an upper anion membrane and a lower cation membrane at the cathode side. CONSTITUTION:An electrode membrane 11 obtd. by vertically joining an upper cation permeable membrane (cation membrane) 11a and a lower anion permeable membrane (anion membrane) 11b of the same size is spread at the anode side of an electrophoretic apparatus. An electrode membrane 12 obtd. by vertically joining an upper anion membrane 12b and a lower cation membrane 12a of the same size is spread at the cathode side to form an electrophoretic chamber and electrode chambers. When voltage is impressed between both electrodes 4, 4, cations from the anode and anions from the cathode enter the electrophoretic chamber through the membranes 11, 12 in the upper part. In the lower part, anions enter the electrode chamber adjacent to the anode and cations enter the electrode chamber adjacent to the cathode because ion exchange membranes having opposite polarities are present and the concn. of ions in the electrophoretic chamber is kept nearly constant, so any electric current affects the concn. of ions in the electrophoretic chamber.

摘要： PROBLEM TO BE SOLVED: To provide a rearing water tank for aquatic organisms for the microgravity environment designed to fix a gas-liquid interface in a prescribed direction in the microgravity environment.
SOLUTION: The water tank is made of a polycarbonate, or the like, for rearing the aquatic organisms in the microgravity environment. In the water tank 1, a gas-phase stabilizer 3 of a lattice structure is made of a hydrophobic material [e.g. Teflon (R) or PTFE (polytetrafluoroethylene)] having worse wettability with water than that of an inner surface of the water tank 1 on the side where the gas-liquid interface is to be formed. The gas-liquid interface is held in the part of the lattice structure having the surface of the worse wettability. An air bladder of the reared aquatic organisms can be inflated or pulmonary respiration can be carried out by using the gas phase. The stable gas-liquid interface can well be maintained in the part of the lattice structure by forming the gas-phase stabilizer 3 into the lattice structure having 10-30 mm dimension interval.

摘要： PURPOSE:To judge the forward and reverse rotations of a rotary gear and to obtain a flowmeter for two directions, by providing two pickups at an angle, which is smaller than 1/2 the angle between projections of the rotary gear of the turbine flowmeter, and comparing the delay time between the detections of the projections. CONSTITUTION:Projections are provided on the rotary gear of a turbine flowmeter at an angle theta2. Two pickups 13 and 14 are provided in the vicinity of the rotary gear. An angle theta1 between the pickups 13 and 14 has a relationship of theta1 t2. By detecting and comparing the times t1 and t2, the forward and reverse rotations of the rotary gear can be detected.
