  • Patent number: 8227360
    Abstract: [Problem to be Solved] A sheet made of a fabric or paper coated with a substance which has a strong function to adsorb, remove and make harmless microbes such as bacteria and viruses is to be configured so as to be usable as a filter, a mask or the like capable of removing the microbes such as the bacteria and viruses. [Solving Means] A sheet made of a fabric which uses a fibrous material, for example, polyester in which a sulfenate group or a carboxylate group has been introduced, and has a surface coated, for example, with anatase type titanium oxide makes microbes such as bacteria and viruses harmless by adsorbing these microbes and has sufficient air permeability, therefore being usable as a filter, a mask or the like.

  • Patent number: 7291266
    Abstract: To compose a composite filter for obtaining water having a high purity usable as water for life and water for medicine from water in which impurities are mixed. Furthermore, to compose an apparatus for obtaining water having a high purity using the filter. Moreover, to configure the apparatus so as to facilitate exchange of the filter. That is, water having a high purity can be obtained by allowing raw water to permeate through a composite filter which consists of a first layer 11 made of fibers, a second layer 12 made of ion exchange resin, a third layer 14 made of activated carbon and a fourth layer 16 made of an unwoven textile. These first layer, second layer, third layer and fourth layer are configured as separate independent filters respectively so that each filter can be exchanged independently. Furthermore, different kinds of filters can be combined dependently on purposes of use.

  • Publication number: 20060235367
    Abstract: A first tube (3) and second tube (7) for guiding aqueous humor to the exterior of the eye are connected to each other in the vicinity of a surface of conjunctiva (14) via a first joint (5) and second joint (6). A filter part (9) provided to prevent reflux infection from the exterior to interior of the eye is connected to the second tube (7) via a third tube (8) positioned inside a lower lacrimal canaliculus (23). This enables an aqueous humor drainage implant (1) to be positioned in the eye and the exterior of the conjunctiva with reduced invasiveness. With the aqueous humor drainage implant for glaucoma treatment, the aqueous humor in the eye can be drained to the exterior of the conjunctiva while preventing reflux infection at the viral level, and the intraocular pressure reducing effect can be sustained for extended time periods over the lifespan of the patient.

  • Patent number: 5041079
    Abstract: The present invention provides removing agents comprising a solid substance with a weakly acidic or weakly alkaline surface. Since the removing agents can be used for treating body fluid of a patient by, for example, extra-corporeal circulation system thereby effectively removing human immunodeficiency virus and/or its related compounds contained in the body fluid, it is expected that the life of the patient could be prolonged. The significance of the present invention therefore is great.

  • Patent number: 4259303
    Abstract: The present invention provides a method of treating a waste anesthetic gas by contacting the laughing gas contained in the waste anesthetic gas with a catalyst comprising one or more metal oxides selected from the group consisting of ferric oxide, cobalt oxide, cupric oxide, chromium oxide, manganese dioxide and nickel oxide to decompose the laughing gas into nitrogen and oxygen. This method is of practical value for preventing the neighborhood of hospitals from environmental pollution problem.
