Title: Discoloring pan paint composition changing in color
Inventor: RICHIYAADO II MIRAA
IPC: C09D11/02
Filed: 1995-10-03
Abstract: PROBLEM TO BE SOLVED: To obtain a coloring system compsn. whose discoloring in multicolor can be enhanced by compounding a water-soluble resin with a dye selected from among three dyes whose colorabilities are destroyed or modified in specified manners.  
     SOLUTION: This pan paint compsn. contains about 20-99.9% water-soluble resin and about 0.1-20% water-soluble dye selected from among a dye whose colorability is destroyed or modified in the presence of a pH of about 10 or higher, a dye whose colorability is destroyed or modified in the presence of a reducing agent, and a dye whose colorability is destroyed or modified in the presence of a pH of about 10 or higher and a reducing agent. The discoloring action of this coloring system is caused by using a low-pH system known as an acid-based or acidic system or by using a high-pH/reducing agent system known as a basic system. In both systems, the colorability of the discoloring dye is destroyed or modified reversibly or irreversibly under specified conditions, i.e., in the presence of a low pH or a high-pH/a reducing agent.

IPC: G01M3/02
Filed: 1999-09-10
Abstract: PROBLEM TO BE SOLVED: To obtain a variable-volume apparatus by which the volume of a voluminous body to be measured can be measured and a leakage tester can be calibrated with high accuracy and efficiently by a method wherein a piston inserted into a cylinder is moved freely between two stop positions to obtain a volume change of a prescribed amount. SOLUTION: A piston 120 is stopped in a stop position I with reference to a cylinder 110. Compressed air under the known same pressure P0 is supplied to a voluminous body 10, to be measured, and a reference volume body 20. Then, the volume V0 of the voluminous body 10 to be measured becomes a value obtained by adding a volume between the piston 120 and the cylinder 110 to the volume of a connection passage 111. Then, when the piston 120 is moved to a stop position II, the volume between the cylinder 110 and the piston 120 is increased by ΔV, and the pressure of the voluminous body 10 to be measured is changed to P0-ΔP, and its volume is changed to V0+ΔV. Then, when the volume V0 is known, a gas-pressure change amount ΔP is found based on the volume V0, the pressure P0 and the volume change amount ΔV, and a differential pressure gage 30 is calibrated.  On the contrary, when the volume V0 is unknow, the volume V0 is found based on the known voluminous body pressure P0, the volume change amount ΔV and the gas-pressure change amount ΔP which is read out from the differential pressure gage 30.

Abstract: PURPOSE:To prevent a damage of a drain pump by arranging a drain cooler between a drain tank and the drain pump and by suppressioning boiling-up of drain by lowering drain temperature at an inlet of the drain pump. CONSTITUTION:Drain in a drain tank 6 is water (drain) of temperature of a saturated condition or of a little one than that, that is, 150 to 200 deg.C. On the other hand, feed water flowing into a drain cooler 16 through a feed water by-pass line 18, is the water of temperature lower than 50 deg.C, which is fluid that steam condensed in a condenser 14 and is pressurized by a condensate pump 20. Accordingly, at the drain cooler 16, the drain flowing out from the drain tank 6 is heat-exchanged with low temperature feed water and is enough cooled down and therewith, even if pressure reduction occurs, the drain does not boil up and therefore there is no danger for the drain to give any damage to the pump.
