Abstract: Disclosed is an apparatus for generating ultraviolet rays and ozone using microwaves to sterilize water in a swimming pool or potable liquids such as purified water, milk and juice and to eliminate impure organic matters contained in the water. The apparatus includes a housing (10) having an upper liquid inlet (12) and a lower liquid outlet (14), and defining a sterilization chamber (16) therein. The housing (10) includes therein a transparent partition wall (18), which is spaced from a side vertical wall of the housing (10) to serve as a side wall of the sterilization chamber (16). The transparent partition wall (18) is provided with several electrodeless ultraviolet lamps (20). Wave guides (22) are attached to the back faces of the electrodeless ultraviolet lamps (20), respectively, which are widened toward the ultraviolet lamps (20). Microwave generator units (24) are attached to back ends of the wave guides (22), respectively.

Abstract: The present invention relates to an improved manufacturing method of a buffer and heat-insulating material made of foamed cellulose substance, wherein cellulose material is heated homogeneously in a microwave oven to be foamed homogeneously and thus when dried the foamed product is not deformed, whereby an excellent buffer and heat-insulating material is obtained.

Abstract: A plasma generating apparatus is provided which uses slipping surface discharge and microwave to generate a large quantity of plasma in a different gases or gaseous mixtures (including electro-negative gases) in a wide range of gas pressure (from a deep vacuum up to atmospheric pressure). The plasma generating apparatus includes high voltage pulse means for generating a high voltage pulse, plasma generating means based on the slipping surface discharge which excites as the high voltage pulse generated by high voltage pulse generating means, is supplied, microwave generating means for generating a microwave radiation for producing plasma, a chamber in which the plasma generating means are placed, and the plasma collects, the chamber receiving the microwave radiation from the microwave generating means, and a gas inlet through which a specific gas flows into the chamber, to generate a large quantity of plasma according to the plasma generating means and microwave generating means.
