摘要： PROBLEM TO BE SOLVED: To prevent the leakage of liquid from a sepn. vessel even if this sepn. vessel is turned down or inverted by mounting a hydrophobic and liquid resistant film material at an outlet for taking gas out of the sepn. vessel. SOLUTION: The hydrophobic and liquid resistant film material 7 which allows the passage of gas but does not allow the passage of liquid and is not damaged by the liquid is mounted in the gas outlet 3 for taking the gas out of the gaseous phase side of the sepn. vessel 1 which consists of ozone resistant blank stock and houses a mixture composed of ozone, oxygen and water. The film member performs the sepn. operation of the gas and the liquid without hindrance by allowing the free passage of the gas and does not allow the passage of the liquid, therefore, even if the sepn. vessel 1 is turned down, inverted or is vigorously shaken for the purpose of inspection, adjustment, repair and others, the liquid does not flow out to the gas outlet 3. Consequently, the contamination and external outflow of the liquid induced by the outflow of the liquid to the gas outlet 3 may be prevented. Safety is insured even if the gas outlet 3 is provided with a member having a danger of giving rise to explosion in case of the occurrence of wetting with water.

摘要： PROBLEM TO BE SOLVED: To achieve an adequate process to decompose ozone using a small- sized, light-weight, low-priced and long-lived device by forming a container filled with a catalyst to the volume appropriate for an ozone throughput and internally retaining a heat generated by ozone degradation on account of a heat-insulating structure. SOLUTION: This ozone decomposition device A is of such a functional structure that an ozone is allowed to pass through an introduction aperture 3 connected to one of the ends of a container 1 filled with a catalyst, into the catalyst, and is decomposed to oxygen to be evacuated from an evacuation aperture 4 connected to the other end of the container 1 into an atmosphere. In addition, ozone-resistant partitions 5 are arranged inside the introduction aperture 3 and the evacuation aperture 4 respectively and a catalyst 2 is retained in the container 1. The container 1 of the ozone decomposition device A is to be less voluminous, and light-weight from the viewpoint of the necessity to manufacture the device of a small size and light weight at a low cost. Therefore, the container 1 is formed to have a volume best suited for ozone treatment, for example, using a pipe of vinyl chloride as a material so that the device is of a heat-insulating construction.

摘要： PROBLEM TO BE SOLVED: To provide a simple and miniature temperature controlled gas-liquid separator in which gas-liquid separation is efficiently performed in temperature control environment by forming a separation vessel of gas and liquid in a shape as thin as possible so as to be equipped with a heat exchange wall having large surface area and directly performing heat exchange by the heat exchange wall and a temperature control means. SOLUTION: In the temperature controlled gas-liquid separator A, such operation is performed in temperature control by a control means 2 that a gas-liquid mixture is introduced into a separation vessel 1 and separated into gas and liquid and both are sent out. The separation vessel 1 is formed into a shape as thin as possible within a range enabling gas-liquid separation and equipped with a heat exchange wall 1a having large surface area. The temperature control means 2 is combined with the heat exchange wall 1a so that heat exchange is directly performed.

摘要： PROBLEM TO BE SOLVED: To reduce the amount of raw material oxygen supplied from a supply source by sending oxygen or a mixture of oxygen and ozone which is discharged from an ozone water producing/holding container to an ozone generator as a raw material for producing ozone. SOLUTION: A mixture of oxygen and ozone collected above the water level L of an ozone water producing/holding container 1 is introduced in a route 3, and a route 6 for sending the mixture to an ozone generator 4 is installed. In an ozone water producing apparatus A, partially ozonized oxygen is infected into water by a route 5 in the discharge type ozone generator 4, ozone water is produced by a part of the ozone which was dissolved, and ozone which was not dissolved and oxygen ascend above the level L and are introduced into the route 3 by way of the route 6 to be sent toward the ozone generator 4. In the process of the repeated operation, the pressure change of the ozone- oxygen mixture is detected by a pressure detector 9, and the raw material oxygen is supplied when the pressure is decreased. In this way, the mixture which was not dissolved in water can be reused so that ozone water of a prescribed concentration can be produced quickly with reduced oxygen consumption.

摘要： PROBLEM TO BE SOLVED: To effectively perform temperature control over corrosive liquid with reduced problems of a leak, icing, and temperature deviation by forming a thin type subordinate container of a nonmetallic thin-film wall and adding a plate type temperature control means to the thin-film wall, and then only supplying the corrosive liquid in a main container to the subordinate container for the temperature control and then putting it back to the main container. SOLUTION: The main container 1 of a device A contains a necessary amount of corrosive liquid and gas or only corrosive liquid and is formed of anticorrosive resin, etc., which is not corroded by the corrosive liquid and connected to the subordinate container 2 by a circulation path 3. The temperature control means 5 is added to the subordinate container 2. This subordinate container 2 contains the corrosive liquid and controls its temperature, and is formed into a thin type by using the anticorrosive resin so that the temperature is performed with as a less partial difference as possible. Then the part of the subordinate container 2 where the temperature control means 5 is added is formed of a thin film wall 2a formed of nonmetallic anticorrosive resin.

摘要： PROBLEM TO BE SOLVED: To provide an automatic water faucet device to achieve the sterilization- washing of a human body without stress. SOLUTION: This automatic water faucet device has a water feeding head 2, a first solenoid valve which is inserted in the middle of a piping 3 to connect the water feeding head 2 and a subsidiary washing water source, a second solenoid valve which is inserted in the middle of a piping 5 to connect the water feeding head 2 and an ozone water source, and a sensor 7 to detect the existence of an object such as hand under a discharging port 21 of the water feeding head 2. Corresponding with a detection signal of the sensor 7, the first solenoid valve is open-driven for a specified period of time A, and at the same time, the second solenoid valve is open-driven for a specified period of time B by delaying it from the start point of the open-driving of the first solenoid valve by a specified period of time C. A graphic displayer 10 by a light emitting element array, which is arranged on the upper face of the water feeding head 2, controls the lighting-up/out of the light-emitting element array by cooperating with a means which controls the solenoid valves, and graphically roughly displays how much of the specified period of time B has passed, and how much of the specified period of time C has passed.
