Abstract: A substantially water-resistant resin-coated aggregate for use in concrete includes a porous aggregate body, such as an artificial light weight aggregate, with an elastic layer made of a phenol resin elastomer deposited on the aggregate body, a rigid phenol resin coated on the elastic covered aggregate body. This resin-coated aggregate has a high water absorption prevention and further an external stress-damping function.

Abstract: Disclosed is a thin film magnetic recording medium which comprises a substrate and a magnetic layer formed on the substrate, the magnetic layer including a lamination composed of at least a grain size suppression film and a magnetic film formed on each of opposite sides of the grain size suppression film, the grain size suppression film being made of at least a grain size suppressing metal, the magnetic film being made of a cobalt magnetic material, and further disclosed is a method of producing a thin film magnetic recording medium which comprises the step of: dipping a substrate in an electroless plating solution for depositing a crystal of a cobalt magnetic material on the substate to form a first crystal film thereon; adding a metallic salt solution for suppressing growth of a grain size of a crystal structure into the electroless plating solution at least once after a predetermined period of time has passed from the dipping of the substrate under the condition that the substrate is dipped in the electrol

Abstract: A bendable thin, sheet-like structure having a cementitious matrix reinforced with a three-dimensional fabric of an organic fiber uniformly distributed throughout the thickness of the structure and a continuous process for its production.
