  • Patent number: 6749806
    Abstract: The present invention relates to a method of sterilizing fungi and bacteria in a spore state for sterilizing fungi and bacteria in a spore state for sterilizing fungi and bacteria in a spore state and a sterilizer thereof. In particular, the invention is directed to a method of sterilizing sterilization targets adhering onto target-adhering things such as containers, packing materials, conveying tools, etc. or sterilization targets contained in target-containing things such as liquid, air, raw materials, etc. and also a sterilizing device thereof. Some of fungi and bacteria in a spore state are strong to ultraviolet rays, and some of them are strong to heat. So, both the fungi and so on which are strong to ultraviolet rays and those which are strong to heat can be effectively sterilized by performing successively the sterilization by UV radiation and heat.

  • Patent number: 5837192
    Abstract: When reactors charged with nitrogen as inert-blanketing gas are opened, high losses of inert-blanketing gas occur which previously have only been able to be compensated for by increased feed of inert-blanketing gas. To minimize the consumption of inert-blanketing gas during temporary opening of reactors (1), a further inert-blanketing gas is admixed to the nitrogen. The inert-blanketing gas mixture in the process has a density which is slightly greater than the density of the surrounding air.

  • Patent number: 5686045
    Abstract: Methods for sterilizing an instrument contaminated with biological matter are disclosed. The apparatus generally includes a container for containing a room temperature antimicrobial solution and a lid that can seal the container such that a gas is trapped within the container and above the antimicrobial solution. The apparatus provides a pressure, independent of heat, within the sealed container to greater than one atmosphere. Vibration is also provided to vibrate the container, and its contents, such that biological matter on the instruments is removed and all microbes on the instrument are exposed to the antimicrobial solution. The pressure drives and forces the antimicrobial solution into the cracks and crevices of the instrument and also into the outer membrane of the microbe, which can be first softened or attenuated by the vibrations.

  • Patent number: 5656242
    Abstract: An air purifier has a perforated plate between UV lamps on the one hand and a porous air filter on the other. Biological material is trapped by the filter and eventually killed by the low dose of UV radiation which passes through the perforations in the plate. Filtered air passing through the plate is subjected to a high dose of UV radiation which sterilizes remaining biological material in the air. An electrostatic filter at the outlet may trap viruses which have been positively charged either by the action of the UV lamps or by positively charging the plate in order to strip electrons from the viruses. The UV lamps may be mercury lamps which are allowed to emit at both their ozone forming wavelength as well as the ozone breakdown wavelength. In such instance, a light filter surrounds the lamps which passes light only at the ozone breakdown wavelength. Air subjected to the unfiltered light is consequently subjected to ozone, which is a known biocide.
