摘要:
The present invention provides an apparatus to prevent the entrance of aquatic species into the intake watercourse having a U-shaped cross section with a narrow bottom and a wide surface, in which oppositely facing electrodes are installed vertically along the side walls on both sides of the intake watercourse, and the distance between the upper ends of the electrodes is made greater than the distance between the lower ends of the electrodes, and a voltage is impressed between the both electrodes. Since the electric barrier intensity is smallest at the surface of water and becomes greater as it goes toward the bottom of water, the river fish moving around the bottom of water make a U-turn when they reach the strong electric barrier, or alternatively, after reaching the strong electric barrier, they move upward to where the electric barrier is weaker and then make a U-turn, thereby the entrance of aquatic species into the intake watercourse can be prevented.

Behind a slidable end sealing member 3c, there is provided a liquid-absorbing element M which has a liquid-holding function so as to absorb and hold a liquid L flowing out from the end sealing member 3c when the end sealing member passes over a bypass portion 6. As this liquid-absorbent element M, such as a disk-like element D and a cylindrical element R, are typically impregnated with a water-holding and liquid-absorbing accelerator to enhance a leak preventing effect and with an antimicrobial active agent to enhance hygiene.
摘要:
A prefilled syringe capable of separate storage of different substances before use. It includes a tubular body having an injection needle at one end and a plunger at the other end, and a partition axially slidable in the tubular body. The partition includes a front part and a rear part independent of each other, and as a whole divides the interior space of the tubular body into a front compartment and a rear compartment in a sealing manner for storing mutually different substances. A bypass is disposed generally between the front and rear compartments to introduce the substance in the rear compartment into the front compartment when the partition is slid under pressure provided by the plunger to be adjacent to the bypass to thereby mix the substances immediately prior to injection.
摘要:
Disclosed is a method of producing microspheres which comprises subjecting a w/o/w emulsion or o/w emulsion to an in-water drying method under the following conditions: 1) the amount of microspheres per m.sup.3 of an external aqueous phase is about 0.1 to about 500 kg, 2) the square root of the area (unit: m.sup.2) of the liquid surface in contact with the gas phase is about 0.2 to about 4.5 per the cube root of the volume (unit: m.sup.3) of an external aqueous phase, 3) the w/o/w emulsion or o/w emulsion is replaced at the replacement frequency of about 0.01 to about 10 times/minutes, 4) a gas is blown to the w/o/w emulsion or o/w emulsion at the gas transfer rate near the liquid surface of about 0.1 to about 300 m/second, and 5) the gas is replaced at the replacement frequency of not less than about 0.5 times/minutes; and the method of the present invention increases the rate of solvent removal from microspheres in in-water drying, reduces the amount of solvent in microspheres in a short time.

摘要:
An auger feeder suitable for use in subdividing and feeding of powdery particles such as precious medicines in a trace amount, because the component parts of the auger feeder can be easily disassembled for sterilization treatment before use. In addition, it can be prevented owing to the electric detection system in the auger feeder of the present invention that foreign particles resulting from the contact or the friction between the components are mixed with the powdery particles.
摘要:
A filling machine provided with a filling amount weighing apparatus which is used in a step of preparing medical supplies and so on, and continuously fills automatically powder, liquid or the like of a very small amount into a container such as vial, ampul or the like so as to weigh the filling amount, on the employment of an electronic balance to effect a weighing operation of high speed and precision so as to improve the filling amount accuracy through the reduction in dispersion in the filling amount.
