Title: Evaluation of contributing space dose in nuclear power facility
Inventor: KITADA YOSHIO
IPC: G01T1/16
Filed: 1980-07-16
Abstract: PURPOSE:To achieve a highly accurate measurement by discriminating whether there is influence of radioactive exhaust mist or not only when the measuring point  is positioned leeward an exhaust cylinder determining whether it is so nor not. CONSTITUTION:A flow chart is shown on this evaluation metod. At a measuring point, measurements are made on the space dose rate with a space dose rate measuring device 1 and on the direction and speed of wind with a wind direction/speed measuring device 2. A lee bearing determining circuit 3 determines whether the point is lee or not. In other words, when the wind velocity is below 1.5-1.0m/sec., the measuring point is leeward regardless of the wind direction measured. When it exceeds the value, the point within the diffusion range of an exhaust cylinder is determined to be leeward. When the point is found to be windward, the dose rate masuring device 1 measures the background dose rate B. When it is found to be lee, a circuit 4 for calculating a standard deviation of the dose rate calculates the standard deviation rate which is compare with a threshold by a comparator 5. Thus, the space dose rate at this point is measured.

Title: Method for increasing dissolved oxygen in water
Inventor: YAMAMOTO MASAHIRO
IPC: A01K63/04
Filed: 1993-04-23
Abstract: PURPOSE:To increase the dissolved oxygen in water or an aqueous solution (oxygen dissolved in water) used for especially liquid culturing of an aerobic microorganism or culturing fishes. CONSTITUTION:Water or an aqueous solution is usually made to flow and circulate on plates superposed in many stages so as to provide 0.3-10cm<2>, usually 0.35-5.0cm<2> surface area per unit volume (1ml) thereof. Thereby, the dissolved oxygen concentration in the water is increased to the saturated dissolved oxygen concentration or above. Since a method for circulating the water or aqueous solution is adopted, there are the following advantages: Only the number of plates may be increased as opposed to the conventional case of blowing air in water with an air pump in which an increase in the capacity of the pump is required with increasing volume of the water. As a result, the operating cost is remarkably reduced. The liquid is always uniformly stirred due to its circulation.
