An ozone generation system comprises an electricity charge unit price storing part which stores an electricity charge unit and a gas charge unit price storing part which stores a gas charge unit price, based on the electricity charge unit price, the gas charge unit price and necessary generation amount of ozone which is required for an ozonized gas, regarding an ozone concentration and a gas flow rate which are ozone generation amount basic parameters, values at which a running cost is a minimum are determined, a gas flow rate controller is controlled so as for a gas flow rate to be the determined gas flow rate and power of a power supply for an ozone generator is controlled so as for an ozone concentration to be the determined ozone concentration.

Ozone generation system and method for operating ozone generation system

An ozone generating apparatus having high reliability in which a glass tube can prevent from being damaged by melting a power feeding brush even if a large amount of short-circuit current flows. In an ozone generating apparatus using silent discharge, an alternating high voltage power is supplied from a power supply to a metal film formed in an inner wall of a glass tube by a power feeding brush comprising a brush shaft made of metal and a large number of metal thin wires fixed to the periphery of the brush shaft, the following equation satisfies.(2/1)&#x2267;1/{1+(1/20&#x3b2;)},

Ozone generating apparatus

An apparatus for replenishing paint into a paint cartridge ( ), which is capable of putting paint in respiratory circulation while the cartridge is in a waiting state. The apparatus includes a replenishing valve ( ) which is capable of feeding paint to and from a paint chamber ( ) of the paint cartridge ( ) which is set on a replenishing stool ( ), and a respiratory paint circulation valve ( ) which is capable of feeding paint-extruding thinner to and from a thinner chamber ( ) of the cartridge. After switching the replenishing valve ( ) to a drain or discharge side, paint-extruding thinner is supplied from the respiratory paint circulation valve ( ) to push paint out of the paint chamber ( ) of the cartridge ( ). Then, after switching the replenishing valve ( ) to the side of a paint supply source, paint-extruding thinner is discharged by way of the respiratory paint circulation valve ( ) to suck paint into the paint chamber ( ). As a consequence, paint in the cartridge ( ) is put in respiratory circulation to prevent separation and sedimentation of pigment components of the paint.
