An apparatus for dispensing drinking water including of a chamber in which a container packed with drinking water is mounted, a conduit connected with the container in the chamber to dispense drinking water through the apparatus, and sterilizer installed adjacent the conduit means to apply sterilization with substantial heat thereto. The sterilizing means may include automatic control system to control automatically sterilizing with heat. The conduit may includes a storage area for storing drinking water within the conduit, and the storage area may includes two tanks for storing drinking water, one is a cold water tank including a refrigeration device to chill the drinking water, and the other is a hot water tank including heating device to heat the drinking water. The sterilization with heat may be done by heating the conduit with heaters installed surrounding thereof, or may be done by circulating hot water which is stored in the hot water tank through the apparatus. Furthermore, the sterilizer installed adjacent said conduit with the exception of the portions in which hot water is usually passed through in the apparatus during dispensing the drinking water to apply substantial sterilization with heat thereto.

A plasma treatment apparatus capable of efficiently performing a plasma treatment to a large area of an object while preventing the occurrence of streamer discharge is provided. The apparatus includes at least one pair of electrodes, gas supply unit for supplying a gas for plasma generation to a discharge space defined between the electrodes, and an electric power supply for applying an AC voltage between the electrodes to generate plasma of the gas for plasma generation in the discharge space. At least one of the pair of electrodes has a dielectric layer at an outer surface thereof. At least one of the pair of electrodes has a curved surface jutting into the discharge space. It is preferred that the electrodes are of a cylindrical structure. In this case, it is particularly preferred that the plasma treatment apparatus further includes a coolant supply unit for supplying a coolant to the interior of the electrodes to reduce an electrode temperature during the plasma treatment.

A plasma treatment apparatus includes two or more pairs of electrodes for plasma generation, a treatment chamber for accommodating the electrodes, gas supply unit for supplying a plasma-generation gas such as rare gas into the chamber, and a power supply. A pulse-like or AC voltage is applied between the electrodes to generate dielectric barrier discharge plasma of the gas in the vicinity of atmospheric pressure, so that an object placed between the electrodes is treated by the plasma. At least one of the electrodes is provided with a tubular electrode substrate and a protection layer formed by heat-fusion coating a glass-based material on at least an outer surface exposed to plasma of the tubular electrode substrate.

Each filter part includes: a first λ/4 multilayer film in which two kinds of thin films having mutually different refractive indices but an identical optical film thickness are alternately stacked; a second λ/4 multilayer film in which the two kinds of thin films are alternately stacked, said second λ/4 multilayer film being formed on the opposite side of the first λ/4 multilayer film from the substrate side, and; and a wavelength selection layer interposed between the first λ/4 multilayer film and the second λ/4 multilayer film, said wavelength selection layer having an optical film thickness different from the optical film thickness of each the thin film according to a desired selection wavelength. A low refractive index material of the first λ/4 multilayer film and the second λ/4 multilayer film is an oxide, and a high refractive index material thereof is a semiconductor material of Ge. A material of the wavelength selection layer is identical to a material of the second thin film from the top of the first λ/4 multilayer film.

An infrared radiation element A heat insulating layer having sufficiently smaller thermal conductivity than a semiconductor substrate, is formed on a surface in the thickness direction of the semiconductor substrate. A heating layer, which is in the form of a lamina (plane) and has larger thermal conductivity and larger electrical conductivity than the heat insulating layer, is formed on the heat insulating layer. A pair of pads 4 for energization are formed on the heating layer. The semiconductor substrate is made of a silicon substrate. The heat insulating layer and the heating layer are formed by porous silicon layers having different porosities from each other, and the heating layer has smaller porosity than the heat insulating layer. By using the infrared radiation element as an infrared radiation source of a gas sensor, it becomes possible to extend a life of the infrared radiation source.
