摘要： PROBLEM TO BE SOLVED: To obtain a discoloration inhibitor for a magnesium alloy which enables the safe and efficient execution of grinding, cutting or barrel polishing to a magnesium alloy, the prevention of rust on the surface thereof, and the prevention of its discoloration. SOLUTION: The discoloration inhibitor for the magnesium alloy contains water soluble amine at least containing 2-amino-2-methyl-1-propanol as an effective component. In the water soluble amine, the above 2-amino-2-methyl-1- propanol is contained in >=10% by weight ratio.

摘要： PROBLEM TO BE SOLVED: To provide a hydraulic cylinder apparatus in which a working fluid can be wasted.
SOLUTION: The apparatus consists of a cylinder, and a plunger slidingly driving to the cylinder. As the working fluid lying in the sliding face region between the cylinder and the plunger, and interacting with the plunger, water is used. The water contains a rust preventive. As the rust preventive, Rusmin (R) is particularly preferably adopted. The Rusmin (R) is making a good result as a rust preventive having excellent rust preventing capacity, is widely known as a rust preventive for steel, is economically moderate, and can be economically wasted as well. The Rusmin (R) is originally a rust preventive, and the working fluid containing this prevents the corrosion and erosion of a cylinder and a piston, and, further, originally has rust prevention effect to the internal circumferential face of fluid machinery in contact with a working fluid.
