  • Publication number: 20080103203
    Abstract: The skin disinfectant, which is able to sterilize skin by the action of a surfactant without damaging skin health conditions, contains water, from which polyvalent cations are removed and to which a sodium ion is added, and a surfactant. The surfactant is, for example, a fatty acid salt. When the skin disinfectant is applied onto skin, fungi and bacteria adhered or parasitic onto skin is sterilized by the action of the surfactant. At this time, the surfactant is not likely to give an irritation to skin due to the action of the water, from which polyvalent cations are removed and to which a sodium ion is added, and thus the skin health conditions tend not to be damaged. Accordingly, the skin disinfectant is useful as a remedy for, for example, a ringworm infectious disease.

  • Publication number: 20080103079
    Abstract: The cleaning agent, which is less likely to retain a surfactant on an object to be cleaned and not to restrict applicable objects to be cleaned, contains water from which polyvalent cations are removed and to which a sodium ion is added, and a surfactant. An example of the surfactant is a fatty acid salt. When the cleaning agent is applied to an object to be cleaned, stain adhered on the object is removed from the object by action of the surfactant. The surfactant hardly remains on the object due to the action of the water from which polyvalent cations are removed and to which a sodium ion is added. Accordingly, the cleaning agent can effectively wash a wide variety of objects, such as kitchens, tableware, food, washstands, bathrooms, toilets, vehicles, clothes and body skin, without damaging texture and deteriorating quality.

  • Publication number: 20080076822
    Abstract: The disinfectant capable of realizing effective sterilization by using a surfactant contains water, from which polyvalent cations are removed and to which a sodium ion is added, and a surfactant. An example of the surfactant is a fatty acid salt. When the disinfectant is applied to an object to be treated, fungi and bacteria adhering thereto are sterilized by the action of the surfactant. The surfactant contained in the disinfectant hardly remains on the object owing to the effect of the water from which polyvalent cations are removed and to which a sodium ion is added, and then is not likely to be a source of nutrient for fungi and bacteria. Accordingly, on the object to which the disinfectant is applied, fungi and bacteria are sterilized and propagation thereof is suppressed, and thus a hygienic state of the object is easily maintained.

  • Publication number: 20080058242
    Abstract: The cleaning fluid, which is easily mass-produced, low priced, and safe and is also free from chemical substances contains water from which polyvalent cations are removed and to which sodium ions are added. When the cleaning fluid is applied to an object to be cleaned, stain adhered onto the object can be removed by action of the water. The object washed with the cleaning fluid is free from remnant of chemical substances, as is often not the case when washed with a cleaning fluid using chemical-substances such as a surfactant, and is therefore safe. Furthermore, since water stain or scale hardly remains on the object washed, new stain is not easily attached. Accordingly, the cleaning fluid is particularly effective when it is used as a cleaning fluid for kitchen sinks, tableware, foods, washstands, bathrooms, toilets, vehicles and clothes.

  • Publication number: 20080057139
    Abstract: The skin-care water, which is able to safely improve skin health conditions, such as dry skin, contains water from which polyvalent cations are removed and to which sodium ions are added, and may contain fragrant materials according to need. When the skin-care water is applied to skin, for example, by means of taking a bath, it improves moisture retention of skin, moisture content of skin, elasticity, texture density and the like without providing side effects, as is often not the case when a skin-care water containing chemical substances is used. Accordingly, the skin-care water is useful as a moisturizing agent for skin, and an improving agent for dry skin, itchy feeling, skin scale and atopic dermatitis.

  • Publication number: 20010012141
    Abstract: A WDM communications line is used as a trunk to which an IP network or a SONET/SDH network is connected as a tributary. Additionally, an ID for identifying each wavelength or path, which is accommodated by a WDM communications line, is assigned to a frame of each wavelength. The ID for identifying a wavelength or a path, and the number held by a transmission device that configures the path are managed. When a fault occurs, the wavelength or the path on which the fault occurs is identified, and the identified wavelength or path is displayed on the screen of a supervisory control device that monitors the entire network. An administrator can recognize at first sight the path influenced by the fault other than the point at which the fault occurs, thereby efficiently maintaining and managing the network.
