Abstract: PURPOSE:To start atomizing within a short time after a power supply is turned ON and to stop the same immediately after the power supply is turned OFF by providing the second heating chamber of large capacity evaporating the water boiled in the first heating chamber of small capacity and a pressure control air passage communicating with the second heating chamber and the upper part of a water supply tank. CONSTITUTION:The water in a water supply tank 8 passes through a water passage 9 and flows in a heating chamber 12 to be heated and boiled. The hot water raised in pressure passes through a water passage 16 by volumetric expansion to flow in a heating chamber 13 and is perfectly evaporated to be injected from a steam nozzle 17. The heating chamber 13 and the upper part of the water supply tank 8 communicates with each other by a pressure control air passage 14 and pressure is applied to the interior of the water supply tank 8 to supply water to the heating chamber 12. Since a small volume of water is evaporated in the heating chambers 12, 13 over two stages, atomizing is started within a short time and it is prevented that hot water is perfectly evaporated to be injected from the steam nozzle 17 as it is. Since the heating chamber 12 has small capacity, temp. rapidly falls after a power supply is turned OFF and atomizing is stopped within a short time.

Title: Scraping of coating and scraping plate therefor
Inventor: YUKI TOSHIMI
IPC: B05C1/08
Filed: 1993-09-06
Abstract: PURPOSE:To keep the quality of a film constant and satisfactory and reduce the frequency of cleaning by arranging an arc-shaped scraping plate in close proximity to the coated surface end part of a film in such a manner that only one point on the tip edge of the plate comes in contact with the coated surface end part, and scraping the build-up of a coating off the coated surface end part following the transport of the film. CONSTITUTION:A scraping plate 10 is flat and a tip edge 10a in contact with a coated surface is formed like an arc. If this scraping plate is used, only one point on the tip edge 10a comes in contact with the coated surface from which a coating 5 is scraped off, as the tip edge 10a is arc-shaped. Consequently, the width and strength of scraping are kept constant, if a contact angle varies delicately, and the coating is scraped off at the contact point. Further, the scraped coating 5 is captured by the tip edge 10a part of the arc and flows downward as it is. Therefore, the coating 5 does no longer spread in the width direction of the scraping plate 10 and a secondary build-up of coating can be prevented from generating.

Title: Water level controller
Inventor: SHINOHARA MASANORI
IPC: G05D9/12
Filed: 1987-09-30
Abstract: PURPOSE:To control the level of each water storing facility despite the fluctuation of the demand value by changing the inflow of water to each water storing facility based on a coefficient of distribution when the water level changing speed exceeds its allowable range. CONSTITUTION:The water level changing values and speeds of the water storing facilities 1-1-1-n are obtained from the detecting signals of water gauges 2-1-2-n and flow rate meters 10-1-10-n respectively. At the same time, the upper and lower limit level changing values are also obtained and it is decided whether the level changing speed is kept under its allowable range or not. Then the coefficients of distribution are also obtained so that the water storing states are known for the facilities 1-1-1-n. When the level changing speeds exceeds its allowable range, the inflow is changed based on the coefficient of distribution for each water storing facility. Thus it is possible to control the amount of water to be supplied to each of facilities 1-1-1-n in response to the error between a water amount operating control pattern of the entire water purifying process and the demand value as well as the water level and its speed even though said error increases. As a result, the water levels of facilities 1-1-1-n are always kept at each target value with no fluctuation.

Filed: 1990-09-18
Abstract: PURPOSE:To prevent a pressure difference between a storage part and the internal part of a case and to prevent the scatter of magnetic fluid by providing a by pass connecting the storage part of magnetic fluid and the internal part of the case. CONSTITUTION:A passage 30 for pressure damage prevention is provided for a shaft 13 lest a circular space 26 surrounded by the spindle shaft 13, pole pieces 21 and 22 and a magnet 23 become a sealed space and lest the function of a magnetic seal is damaged. In the passage 30, a part 30a extending in the direction of a radius is opened to the storage part 26 of magnetic fluid 24 and a part 30b extending in the direction of the shaft is opened to the internal part of the case from the upper end of the shaft 13. When the temperature of the storage part 26 is lower than that of the internal part of the case, the pressure of the internal part of the case is larger and air flows into fluid 24 through the passage 30. When the temperature of the storage part 26 is higher on the other hand, pressure in the internal part of the case is low and air in the storage part 26 flows into the internal part of the case through the passage 30. At that time, fluid 24 itself is held by the magnet and therefore it does not flow out. Thus, the scatter of magnetic fluid 24 can be prevented.
