Patent number: 6890648Abstract: A paint composition containing a corrosion inhibitor A prepared from porous silica particles, to which Ca ion is bonded by ion-exchange, and a polyphosphate B preferably at an A/B weight ratio of 60/40 to 5/95 and at an A+B ratio of 5-150 parts by weight based on 100 parts by weight of resinous components. A base metal sheet is preferably one pre-treated with a chemical agent containing at least one fluoroacid. Since the polyphosphate B controls dissolution of Ca ion, an effect of Ca ion on corrosion inhibition is maintained over a long term. The painted metal sheet does not put harmful influences on the environment, since it does not contain chromium compounds.Type: GrantFiled: May 30, 2001Date of Patent: May 10, 2005Assignee: Nisshin Steel Co., Ltd.Inventors: Hirokazu Yano, Yoshikatsu Udagawa, Minoru Kiyotsuka, Kiyoshi Takatsu

Patent number: 5015863Abstract: This invention relates to a shielding material used as a radiation shield of a container containing radioactive wastes. A radiation shield with an excellent heat-transferring property is fabricated from composite particles (A) obtained by coating core particles (a) of radiation-shielding property with a metal (b) of high thermal conductivity. Composite particles are formed into a certain shape of radiation shield by hot-press forming or other forming or packed into the internal space of radioactive waste container or the shield container cavity to compose a radiation shield.Type: GrantFiled: January 23, 1990Date of Patent: May 14, 1991Assignees: Sumitomo Heavy Industries, Ltd., Nisshin Steel Co., Ltd.Inventors: Eiki Takeshima, Kiyoshi Takatsu, Norio Asano, Masahiro Hozumi

Patent number: 4954235Abstract: Disclosed herein suspension electroplating of fine particles with metal. An electroplating operatively equipped with a cathode and anode is charged with a a metallic ion-containing electrolyte and particles to be electroplated. The particles have a size of from 0.1 to 10 .mu.m. At least a part of the surface of each particle is conductive. Such a stationary circulating flow of a suspension of the particles in the electrolyte is formed in the bath that the particles are maintained in the suspended condition; the suspension is circulated substantially without coming in contact with the anode; the particles may have a chance of colliding with substantially all surface areas of the working surface of the cathode, and are repeatedly brought in collision with the cathode at a velocity with a normal component of from 0.6 to 6.0 m/min; and a particle concentration of the suspension at the time of collision is from 30 to 55% by volume.Type: GrantFiled: December 27, 1989Date of Patent: September 4, 1990Assignee: Nisshin Steel Co., Ltd.Inventors: Eiki Takeshima, Kiyoshi Takatsu, Youichi Kojima, Takahiro Fujii
