In order to assure temple-to-front connection to be tight still permitting the stable opening-and-folding of the temple relative to the front, each hinge assembly fixed to joint piece (2) has an engagement piece (4) having an axle (6) transversing in its recess end (7), and a hollow sheath (5) having a lever (18) pivotally fixed to its open end and a spring-biased slider (12) contained therein. The slider (12) has a hook end (13). The engagement piece (4) is fixed to the joint piece, and the sheath (5) is fixed to the temple (1). The temple is connected to the front (3) by inserting the hook (13) of the slider in the recess (8) of the engagement piece (4), and then the temple is pulled to the engagement piece by the resilient force, which is applied to the slider all the time.

To provide a decontamination method and system for soil and the like for decontaminating soil such as fields and water contaminated with radioactive materials reliably and rapidly on site, performing decontamination with precision, and enhancing the efficiency of decontamination. The invention improves the decontaminated soil by adding a soil activator to the decontaminated soil, and then the improved soil is returned to the original field readily to promote the restart of farming. Further, the invention separates the radioactive materials adhering to or deposited on the soil from the soil precisely and then the radioactive materials are concentrated. The invention enables a reduction in the volume of the contaminated soil and achieves a safe treatment of the radioactive materials. An object to be decontaminated contaminated with radioactive material is introduced into an acid eluting solvent to dissolve the radioactive material. The radioactive material dissolved is concentrated and separated from the eluting solvent in the present method. The object to be decontaminated comprises contaminated soil and contaminated liquid. One or both of the contaminated soil and the contaminated liquid are collected and introduced into the eluting solvent. The radioactive materials and the object to be decontaminated dissolved in the eluting solvent are separated into solid and liquid. The decontaminated soil separated from the eluting solvent is collected. The eluting solvent used for separating the radioactive material and in which radioactive material is dissolved is concentrated.

An anodization method which is suitable for the formation of an aluminum oxide film and electrolytic polishing, eliminates the use of a strong-acid electrolyte, employs carbonated water as an electrolyte, can form an oxide film inexpensively and quickly, improves a forming job and streamlines waste water treating, requires no special equipment, prevents a rise in electrolyte temperature, purges oxygen produced around a member to be treated to ensure a stable oxide film formation and a quality oxide film, and uses supercritical carbon dioxide to streamline oxide film forming treating and improve productivity; and a treating device therefor. A member to be treated (3) is used as a cathode in an electrolyte to carry out electrolysis. An oxide film is formed on the surface of the member to be treated (3). Pressurized carbon dioxide is dissolved in a specified amount of water (7). An oxide film is formed by using as an electrolyte carbonated water having a specified acid concentration.
