A plasma generating apparatus comprises a pair of electrodes consisting of an electrode connected to an AC power source and a grounded electrode. An inorganic dielectric substance containing barium titanate as a principal component is filled between the electrodes. It is possible to generate a stable and uniform glow discharge under the atmospheric pressure at low cost by applying a considerably low voltage between said electrodes.

Plasma generating apparatus, plasma generating method and gas processing method by plasma reaction

Provided are a discharge generating apparatus, a discharge generating method, and a gas decomposing method capable of generating a large amount of an atmospheric plasma and increasing processing efficiency of a plasma processing, gas decomposition, or the like, by such a configuration that at least either one of high-potential and low-potential electrodes is comprised of a plurality of electrodes, a space between the electrodes is filled with an inorganic dielectric having a structure permitting flow of a gas, and a glow discharge is generated between the electrodes to change the gas existing between the electrodes, into a plasma under ordinary pressure.

Discharge generating apparatus and discharge generating method

Disclosed is a washing method in which parts and products are washed free of residual smudges without using fleon-family solvents. The method of washing members such as parts or products comprises a first degreasing step for degreasing in nonaqueous liquid the members to be washed after worked, a second degreasing step for degreasing the members being washed in an aqueous liquid which dissolves the nonaqueous liquid, a finish washing step for washing in the aqueous liquid, a rinsing step, and a drying step, wherein the drying step is performed in a plurality of pure water baths, the temperature of a last pure water bath is established to a range of 70.degree. to 85.degree. C., and the washed members are taken out from the pure water bath for drying the surfaces thereof. Also, the washing method is disclosed in which pure water in a plurality of the pure water baths has temperature gradient in the sequence of washing steps. Furthermore, the washing method is disclosed in which the speed of taking out the washed members from the last pure water bath is established so as to be in inverse proportion to the surface area of the washed member.

Washing method

An intraocular lens having a lens base and a coating layer disposed on or otherwise operably associated with a first surface of the lens base. The coating layer is formed by, for example, plasma polymerization of a monomer gas while simultaneously sublimating or evaporating an ultraviolet absorber, thereby forming an intraocular lens which absorbs ultraviolet rays and prevents any free monomer or other substance from oozing out of the lens base and permeating the eye. The properties of the intraocular lens can be readily varied by selecting different monomer gases.
