摘要:
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.

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.

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.

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.
摘要:
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. The disinfectant is particularly effective when it is used for, for example, bathrooms, tabs of washing machines, kitchens, toilets, washstands, drainpipes and daily commodities.

An insulating coating (6) formed of engineering plastic with high heat resistance, high-pressure resistance, and chemical resistance is formed on a surface of a water-level detecting electrode part (3) of an electrode rod for detecting water-level (1) attached to penetrate a metal container (5) communicating with a boiler (7) and including an external power supply connecting terminal part (2) projecting outside the container (5) and the water-level detecting electrode part (3) projecting inside the container (5). One side of a power supply (27) is connected to the external power supply connecting terminal part (2), and another side of the power supply (27) is connected to the container (5) for energization. An electrostatic capacity between the water-level detecting electrode part (3) and the container (5) is measured by using the insulating coating (6) formed on the surface of the water-level detecting electrode part (3) as a dielectric. The water-level of water to be brought into contact with the water-level detecting electrode part (3) in the container (5) can be detected from the electrostatic capacity. Proportional target water-level in the boiler (7) is set based on at least one of the burning capacity, vapor pressure, supply water temperature, and electrical conductivity of boiler water, and at least one of the burning capacity, vapor pressure, supply water temperature, and electrical conductivity of boiler water during operation of the boiler (7) is detected. A difference between the proportional target water-level to be specified by the detected values and actual water-level in the boiler (7) detected by the electrode rod for detecting water-level (1) is constantly calculated. A supply water amount is controlled such that water supply is stopped when the actual water-level exceeds the specified proportional target water-level and the water is supplied until the actual water-level reaches the specified proportional target water-level when the actual water-level falls short of the specified proportional target water-level. In this way, a good quality vapor with high dryness can stably be obtained, and a safe operation of the boiler can be conducted.

摘要:
A multitubular once-through boiler which exhibits an excellent heat transfer efficiency and requires a relatively smaller installation area. The multitubular once-through boiler comprises a combustion device, a ring-shaped upper header which functions as a vapor chamber, a ring-shaped lower header which functions as a water chamber, a plurality of vertical water-tubes connecting the upper and lower headers to form a single-row ring-shaped water-tube wall, a combustion chamber which is a cylindrical inner space surrounded by the water-tube wall, and a ring-shaped combustion gas passage formed between the water tube wall and an outer wall of the boiler. The water-tubes each has a spiral channel grooved on the surface thereof and is in contact with adjacent water-tubes. The area next to each two adjacent water-tubes, on the side of the tubes facing the outer wall of the boiler, has a barrier plate disposed in contact with the water tubes. The barrier plate has an approximately V-shaped cross-section corresponding to the configuration of said area.The multitubular once-through boiler may further comprises a partition wall for dividing the cylindrical inner space of the water-tube wall into the combustion chamber and a flue.
