CONSTITUTION:An upstream fluid diode 15a is arranged onto a fluid transfer pipe between a fluid feed tank 1 and a front stage gas piston 2a, and a downstream fluid diode 15b is also arranged onto the fluid transfer pipe between the front stage gas piston 2a and a delivery pipe 3. And a rear stage gas piston 2b is arranged between the downstream diode 15b and the delivery pipe 3. Operations are controlled by a control device 11 protected by concrete walls. A pressurizing jet pump 8a and a depressurizing jet pump 8b are connected with the front stage gas piston 2a, and a pressurizing jet pump 8c is connected with the rear stage gas piston 2b.

摘要： PURPOSE:To maintain pumping discharge constant by adjusting a forced displacement of a gas piston according to a pump head change due to the liquid level change in a supplying tank, in a fluid pumping device constituted of fluid diodes. CONSTITUTION:In a fluid pumping device constituted of vertical flow type fluid diodes 15a, 15b, the command of a controller 11c closes an electromagnetic valve 11a and opens a valve 11b to introduce compressed air to a jet pump 8b for pressure reduction, thereby, solution in a liquid supplying tank 1 is drawn into a gas piston 2, and next, the electromagnetic valve 11a is opened and the valve 11b is closed to introduce compressed air to a jet pump 8a for pressurization to discharge the solution in the gas piston 2 in an ejection pipe 3. Hereupon, the controller 11c maintains pumping discharge constant by adjusting a forced displacement of the gas piston 2 according to a change in pump head due to a liquid level change in a supply tank 1. Accordingly, a plant process flow on the ejection side can be leveled, and structural elements such as a temporary storage tank, etc. for flow stability become unnecessary.

摘要： PURPOSE:To manufacture a reflection preventing film by adjusting a colloidal solution of specific magnesium fluoride to which water glass is added and performing coating and heating processes. CONSTITUTION:Magnesium acetate of 12.96g and polyvinyl alcohol of 7.5g are weighed/taken and water is added to this mixture so that the whole weight becomes 213g. This aqueous solution is much stirred. Next, hydrofluoric acid of 4.8g is weighed/taken and water is added to it so that the whole weight becomes 154.8g. The latter aqueous solution is poured into the former aqueous solution and this mixture is stirred for several tens minutes. Thus, a transparent colloidal solution of magnesium fluoride is adjusted. Next water glass (Li2O.3.5 SiO2) of 0.6g is weighed/taken and it is diluted by water so that the whole weigh becomes 20g. This solution is poured into the 20g said colloidal solution of magnesium fluoride and this mixture is much stirred. A film of prescribed thickness is formed on a glass plate by a rotational coating process of this mixed solution. When a heating process is next performed, a reflection preventing film which is too hard to be scarred can be manufactured.

摘要： PURPOSE:To obtain a photosensitive composition having high sensitivity and capable of giving an adhesive property with the rays of light by incorporating at least one of diazonium compds. selected from a specific diazonium ion salt or double salt thereof and at least one of nitrate salts selected from the group of a calcium nitrate and a magnesium nitrate to the titled composition. CONSTITUTION:The titled composition is comprised at least one of the diazonium compds. selected from the group of the diazonium ion salt or the double salt thereof shown by formulas (I), (II) and the calcium nitrate and/or the magnesium nitrate. The diazonium compd. is the salt or the double salt obtd. by combinating the diazonium ions of formulas (I), (II), and the Lewis acid such as Cl, a chloride, BF4, and H2SO4. The titled composition may be contained a water soluble org. high polymer compd. and/or a surface active agent to improve a coating property, when forming the film. In order to uniformly mixing the calcium nitrate and/or the magnesium nitrate, the water soluble org. polymer compd. is preferably added >=20wt% on the basis of the aromatic diazonium compd. to the composition, thereby obtaining the titled composition having the high sensitivity, and the improved photoadhesive property.

摘要： PURPOSE:To form black matrix through simple and easy process by performing pattern exposure on a film of photo-viscous compound then adhering specific powder and exposing entirely thereafter adhering ferrite compound powder. CONSTITUTION:Photo-sensitive compound film exhibiting viscosity through exposure while containing water soluble aromatic diazonium salt is formed on a substrate. Then said film is chemically exposed with specific pattern and contacted with specific powder to adhere the powder at least one time. Thereafter chemical radiation is applied entirely on the film to contact ferrite compound powder to adhere said powder on the portion where specific powder pattern is not formed yet. Said ferrite powder is shown by general formula M Fe2O4 (Where M is metal ion of more than one kind of Ni , Co , Ba , Mn , Zn , Cu , Sr , Pb , Mg , Ca ).

摘要： PURPOSE:To secure such a black matrix phosphor screen that is excellent in both brightness and picture quality, by treating the black matrix phosphor screen, made up of using a light cohesive substance, with an aqueous solution containing a polymeric coagulating agent and a surface active agent. CONSTITUTION:Applying and drying a light cohesive substance a panel, a film is formed up, then three-colored phosphor stripes are made up inside the panel in regular sequence. Next, with an aqueous solution of, for example, 0.05wt% polyacrylic amide as a polymeric coagulating agent and 0.5wt% polyoxyethylenealkylphonolether as a surface active agent by way of example, the formed phosphor film and the panel stuck with a black matrix film are treated, by means of washing. With this, not only superflour light cohesive and light absorbent substances are dissolved and removed but also a black matrix phosphor film can be well fixed, so that such a phosphor screen as being excellent in both brightness and picture quality can be thus secured.
