摘要:
An air cleaning apparatus capable of predicting a breakthrough time of a filtering portion is provided. Regarding a mask 1 as one example of the air cleaning apparatus, data on concentration of the poisonous gas element with which in ambient air (40) is contaminated on the upstream side of a filtering portion (3), a flow rate of the air (40) passing through the filtering portion (3), a temperature of the air (40), and relative humidity of the air (40) are input to an arithmetic processing unit (25). A breakthrough-time prediction formula in which the concentration, the flow rate, the temperature, and the relative humidity are provided as variables is programmed in the arithmetic processing unit (25), and the breakthrough time of the filtering portion (3) is calculated through the prediction formula, based on the data on the concentration and the like.

The purified air discharge device comprises a push hood (2) comprising an air flow discharge surface (23) discharging a uniform purified air flow. The push hood (2) is provided with a lateral air discharger (28) for creating a purified air flow that collides against a surrounding wall that is formed as the push hood (2) is installed and that is situated close along the circumferential direction of the air flow discharge surface (23) of the push hood (2).

A toxic gas exposure preventing system for an anatomic practice room is provided which not only can obtain a satisfactory toxic gas exposure preventing effect without impairing workability but also permits the use of existing dissecting tables as they are without requiring any special work such as an exhaust duct installing work. A push hood having a uniform air flow blow-off mechanism and a pull hood having an air flow suction/exhaust mechanism are disposed independently of each of the dissecting tables in such a manner that at least a portion of a uniform air flow passes in contact with a donor body on the dissecting table and is thereafter sucked into the pull hood. Further, a filter having a toxic gas adsorbing function is installed within the pull hood.
摘要:
This invention relates to a method for preparing a proliferation inhibitor for malignant tumour cells of animals including human beings, and the method comprises the steps of cultivating the malignant tumour cells of the animals, afterward transferring them to a culture medium for extraction, adding glucose to the medium, carrying out a cultivation therein, afterward removing the malignant tumour cells therefrom, and collecting the remaining culture medium.
摘要:
The local air cleaning apparatus 1 causes a cleaned uniform air flow blown out from an air flow opening face 23 to collide with an air collision face W to flow outside an open region, so as to cause cleanliness to be higher inside a guide 3 and inside the open region than other regions. Additionally, the apparatus 1 includes at least one of a device for measuring pressures inside the guide 3 and inside a push hood 2, a device for measuring the cleanliness inside the guide 3 or of the open region, and a device for measuring a gap area between the guide 3 and the air collision face W, and, to ensure the cleanliness from a result of the measurement, controls such that a flow velocity of the cleaned uniform air flow blown out from the air flow opening face 23 can be decelerated or accelerated.
