摘要:
A second housing whose center portion is depressed and whose end portion around the center portion is formed like a visor is arranged around a first housing whose center portion is depressed and whose end portion around the center portion is formed like a visor, and a hollow portion is formed between the first housing and the second housing by sandwiching a packing between the end portions of the housings. Further, degassed water for preventing empty heating is filled in the hollow portion, and an ultrasonic transducer is placed on the surface of the center portion of the first housing. A weight for preventing the vibration of the wall is provided on the wall surface of the second housing. Since the vibration of the wall of the housing is suppressed by the weight, vibration energy returns toward the bottom surface of the center of the housing through water and is radiated from the bottom surface efficiently as ultrasonic waves.

A gas solution producing device having a simple structure to reduce a start-up time, and capable of reducing an amount of gas or solution for use, and a method therefor, as well as a cleaning device employing them. An ozone water solution producing device of the present invention includes a gas dissolving module for bringing ozone gas and deionized water in contact with each other for production of ozone solution, a gas introducing pipe for introducing ozone gas from an ozone gas producing device to the gas dissolving module, a buffer, connected on the gas introducing pipe, for temporarily storing ozone gas and thereafter discharging the gas stored to the gas introducing pipe, a first valve for opening or closing the gas introducing pipe to switch introduction and suspension of gas flow to the gas dissolving module, and backflow prevention valve for preventing a backflow of the gas discharged from the buffer.
摘要:
Deionized water from a deionized water source (21) for electrolysis is supplied by a pressurizing pump (20) to an electrolyzer (2) to obtain a hydrogen gas and ozone gas by means of electrolysis. The pressures of these gasses are maintained at not less than the atmospheric pressure. These gasses at a pressure of the atmospheric pressure or more are dissolved in high-purity water in gas dissolving units (6,7) to obtain ozone water and hydrogen water respectively. These ozone water and hydrogen water are introduced into mixer (8,9) to adjust pH respectively. In this way, highly-concentrated, gas dissolved cleaning solution is prepared in a short period of time.

There are provided a method and an apparatus for removing electrostatic charges from high resistivity liquid. An insulating film is formed on the surface of a conductive element which is in contact with the high resistivity liquid wherein the insulating film has such a thickness that a tunneling current may flow through the insulating film, thereby preventing the highly purified high resistivity liquid from being contaminated, as well as from becoming acid. Thus, objects to be treated with the high resistivity liquid become free of electrostatic charges without any contamination.

The wet treatment liquid feed nozzle of the invention comprises an introducing path 10 having an introducing port 7, a discharging path 12 having a discharging port 15, a crossing section 14 formed by causing the introducing path 10 and the discharging path 12 to cross at the other ends thereof, a nozzle assembly 50 having an opening section 6 opening to an object to be treated 1, provided at the crossing section 14, and pressure control means 13, for controlling the difference between the pressure of the wet treatment liquid in contact with the object to be treated 1 and the atmospheric pressure provided at least on the discharging path 12 side so that the wet treatment liquid having been in contact with the object to be treated 1 via the opening section 6 does not flow to outside the discharging path 12.
摘要:
A surfactant is added to anodic or cathodic water obtained by electrolyzing deionized water or high-purity water. Then, an object of treatment is treated with the anodic or cathodic water containing the surfactant. The object of treatment may be treated, in this way, while irradiating it with an ultrasonic wave having a frequency between 30 kHz and 3 MHz. Furthermore, the anodic or cathodic water is continuously jetted or dropped onto the object of treatment from a nozzle, while irradiating an ultrasonic wave at least at a part in the feed pipe of the anodic or cathodic water.
