  • Patent number: 7473298
    Abstract: Charged fine particulate water is provided, which has a nanometer particle size, for example, a particle size of 3 to 100 nm, and contains radicals such as hydroxyl radicals and superoxides. This charged fine particulate water can be generated by applying an electric-field intensity of 700 to 1200 V/mm between a pair of electrodes, while supplying water between the electrodes. By allowing the thus obtained charged fine particulate water to diffuse into an indoor space, it is possible to effectively remove bad odor components/bacteria from the indoor space.

  • Patent number: 6400013
    Abstract: A thermoelectric module is capable of successfully reducing the heat stress for increased reliability. The module includes a plurality of thermoelectric chips of P-type and N-type arranged in a matrix between sets of first and second contacts to form a series electrical circuit. The chips are arranged to give at least three chip arrays each having a limited number of the chips. A first carrier is provided on one side of the chips to carry the first contacts and to include first bridges each integrally joining two adjacent first contacts to define first discrete couples for electrical connection of the chips in each chip array. The first carrier further includes at least two inter-array bridges which are solely responsible for electrical interconnection between the adjacent chip arrays.
