The sterilizing effect of particle irradiation on microorganisms for the sterilizing treatment thereof can be evaluated. The evaluation can be done by supplying microorganisms in the space inside a container (), allowing particles () for the sterilizing treatment of microorganisms to irradiate the microorganisms, sampling the microorganisms by a sampling means () after the irradiation of the particles () and measuring the sampled microorganisms. The microorganisms as the subject for the sterilizing treatment can be a combination of one or more members selected from the group consisting of bacteria, mycete, viruses and allergens. As the particles, for example, positive ions, negative ions, and gases of positive ions and negative ions in mixture, charged particles such as &#x3b1; rays and &#x3b2; rays, various plasma gas particles, particles such as ozone and radical particles, and particles of chemical agent can be used.

An ion generating device generates O(HO)(where n is a natural number) as negative ions and H(HO)(where m is a natural number) as positive ions, and discharges those ions into the air so that airborne germs are killed through an oxidation reaction by hydrogen peroxide HOor radical hydroxyl OH generated through as an active species a chemical reaction between the negative and positive ions. Satisfactory sterilization is achieved when the negative and positive ions are generated in such a way that the concentrations of the negative and positive ions are both 10,000 ion/cc at a distance of 10 cm from the point at which they are generated.

When the electrically driven fan () of a vacuum cleaner is driven, air containing dust is drawn into the cleaner main body () through a hose () connected to a hose socket () and is exhausted into the outside of the cleaner main body () through an exhaust port () via first and second suction passageways (). Disposed outside the first suction passageway () is an ion generator (), it being arranged that plus and minus ions generated in the ion generator () are fed to the air stream flowing in the first suction passageway (). Since the plus and minus ions kill floating germs in the air stream, the exhaust can be purified.

Sterilization method

An air conditioning apparatus incorporates an ion generating device that generates positive and negative ions by applying an alternating-current voltage between electrodes. The generated positive and negative ions coexist in the air and, when they attach to the surfaces of airborne bacteria, they react chemically with each other and generate radical hydroxyl and hydrogen peroxide, which extract hydrogen atoms from the cells of the bacteria and thereby kill them. This sterilizing effect is combined with the temperature-conditioning, dehumidifying, humidifying, air-purifying, and other functions of the air conditioning apparatus to bring about a comfortable and healthful indoor environment.

A copper substrate is immersed into a solution in which a Y-Ba-Cu-O series oxide superconducting fine powder is dispersed into an acetone solution and an electric field is applied thereto. A coating deposited on the copper substrate by electrophoresis is sintered with high temperature in vacuum or in an inert gas atmosphere and then subjected to heat-treatment for oxygen composition ratio in an atmosphere of oxygen or air under 500.degree.

This method prevents occurrence of a CuO layer, which would conventionally be formed at an interface between a Y-Ba-Cu-O film and a Cu substrate disadvantageously, and moreover enables fabrication of superconducting coatings having satisfactory characteristics.
