    摘要： A nuclear power plant using a structural material consisting of metal which comes into contact with a liquid in which radioactive substances are dissolved has a function to suppress the deposition of the radioactive substances. In this function, metal elements constituting the surface layer of the structural material which comes into contact with the liquid are oxidized by injecting oxidizing agents from outside, thereby preliminarily producing an oxide film. The oxidizing agents comprise at least one kind selected from the group consisting of oxygen, hydrogen peroxide, chromate, nitrite, molybdate, tungstate and ferrate. Particularly, by suppressing the deposition of radioactive substances on a stainless steel, the dose rate of exposure of workers is effectively reduced.

    摘要： The present invention is concerned with a method of reducing radioactivity in a nuclear plant by preliminarily forming oxide films on the surfaces of metallic structural members to be in contact with high-temperature and high-pressure reactor water containing radioactive substances before said metallic members are exposed to said reactor water. The method is characterized by the steps of subjecting said structural members to a first-step oxidation treatment of heating said structural members in an environment of a high temperature, and further subjecting the thus treated structural members to a second step oxidation treatment of heating said treated structural members in an environment having a higher oxidizing capacity than that of said environment in said first-step oxidation treatment to form a denser oxide film than an oxide film obtained in said first step oxidation treatment. According to the present invention, radioactivity in the nuclear plant can be reduced remarkably.

    摘要： In a boiling water-type, nuclear power plant, deposition of radioactive substances on the surfaces of out-of-core components in the primary cooling water system in the nuclear power plant is suppressed by injecting an alkaline element into reactor water in the presence of more than an amount of the oxygen formed by nuclear fission of the reactor water and dissolved in the reactor water, particularly without hydrogen gas injection, during the nuclear heatup operation period of a boiling water type, nuclear power plant and circulating the injected alkaline element through the primary cooling water system of a nuclear reactor, thereby forming an oxide film on the surfaces of out-of-core components in the primary cooling water system of the nuclear reactor. Exposure of plant personnel to radioactivity can be reduced thereby. The present boiling water-type, nuclear power plant is provided with a means for forming such oxide film.

    摘要： Provided is a head gimbal assembly (HGA) in which the electrodes for a thermally-assisted magnetic recording head comprising a light source, a photodetector and a magnetic head element, can be reliably electrically connected to wiring members by solder ball bonding (SBB). The HGA comprises a suspension comprising: a base; a first wiring member for the light source and the photodetector, provided on a side of one surface of the base; and a second wiring member for the magnetic head element, provided on the same surface side. The first and second wiring members protrude from the base toward the head to be fixed. As a result, the end portions (connection pads) of the first and second wiring members can be located close to electrodes for light-source and photodetector and electrodes for magnetic head element, respectively. This arrangement enables the end portions of the first and second wiring members to be reliably electrically connected to the electrodes by SBB.

    摘要： A probe assembly used to lap a bar, the bar being provided with elements that are to be formed into sliders, is provided. The probe assembly comprises an elastically deflectable probe, and a stopper for applying bending deformation to the probe so as to cause first bending deflection at a leading end of the probe and for maintaining the first bending deflection of the leading end while preventing a bending deformation at the leading end from becoming smaller than the first bending deflection. The leading end of the probe is adapted to be subjected to second bending deflection that is larger than the first bending deflection in a same direction as a direction of the first bending deflection and thereby to abut against an electrode pad to establish electrical connection between the probe and the electrode pad, the electrode pad being provided on a surface of the bar other than a surface to be lapped.
