摘要： A method for preventing the elution of lead and/or nickel from a copper alloy piping material such as a valve or a pipe joint into a fluid, which comprises cleaning at least the portion contacting with a fluid of the copper alloy piping material containing lead and/or nickel with a cleaning fluid containing nitric acid and hydrochloric acid as an inhibitor under a condition such that the temperature and time are sufficient for effectively removing lead and/or nickel, and forming a coating film on the surface of the portion contacting with a fluid by the action of the above-mentioned hydrochloric acid, to thereby effectively remove lead and/or nickel from the surface layer of the portion contacting with a fluid. The method allows the prevention of the elution of nickel through the removal of the nickel attached to the inner surface of a piping material with reliability and allows the efficient (with respect to treating temperature, treating time, and the like) treatment for preventing the elution of lead and/or nickel. The method also allows the utilization of products obtained by neutralization of various fluids having been used in treatments for preventing the above-mentioned elution as water for industrial use, which leads to great reduction of the cost for the above treatment and to the provision of an environmentally friendly technology.

摘要： The object is to provide a polymer actuator capable of being utilized for any of various drive sources, wherein the amount of deformation of the polymer actuator can particularly be used also for a valve or shaft-sealing device. The polymer actuator comprises a power driver deformed upon receiving electro stimuli and electrodes disposed on the upper and lower surface sides of the power driver in an opposite manner for applying positive and negative electro stimuli to the power driver in a planar fashion. The electrodes have different stimuli application regions to have different electrical field distributions for causing distribution of stress generated in the power driver to be eccentrically located on one of positive and negative sides, thereby bending and deforming the power driver onto a side on which the opposite stimuli application regions do not exist.

摘要： A copper-based alloy characterized by being an alloy which has a composition consisting of 58.0-63.0 wt.% copper, 0.5-4.0 wt.% lead, 0.05-0.25 wt.% phosphorous, 0.5-3.0 wt.% tin, 0.05-0.30 wt.% nickel, and the balance consisting of zinc and unavoidable impurities and has homogeneously and finely divided structure so as to have excellent corrosion resistance and hot workability, and by being an alloy which becomes excellent also in resistance to stress corrosion cracking through an appropriate drawing and heat treatment by both of which mechanical properties, e.g., tensile strength, proof stress, and elongation, are improved and the internal stress is sufficiently removed. The copper-based alloy has the hot forgeability inherent in lead-containing brass and has excellent resistance to dezincification corrosion. It is economically advantageous because the material cost is low due to the use of phosphorous for improving corrosion resistance. Furthermore, it becomes excellent also in resistance to stress corrosion cracking through an appropriate drawing and heat treatment.
