Title: Method for modifying surface of steel
Inventor: HISAMOTO ATSUSHI
IPC: C23C14/58
Filed: 1993-12-22
Abstract: PURPOSE:To produce a surface treated steel showing excellent corrosion resistance even to halogen gases by subjecting a Ti layer and/or a Ti compound layer with a prescribed thickness formed on the surface of a steel to heating treatment and forming a mixed layer of the oxide and carbide of Ti. CONSTITUTION:A steel contg., by weight, 0.01 to 1% carbon is prepd. On the surface of this steel, metal Ti layer and/or a Ti compound layer with 0.05mum thickness is formed, e.g. by a vacuum deposition method or the like. Next, this is 9 subjected to heating treatment at >=600 deg.C to form a mixed layer of Ti oxide and Ti carbide. Then, high corrosion resistant Ti oxide is formed, and, by the reaction with carbon diffusedly moving from the inside of the steel, Ti carbide is formed, by which the fine gaps of the Ti oxide are filled, and densification is executed.

Filed: 1989-12-15
Abstract: PURPOSE:To form the electrostatically charged thin layer of one-component developer on a developer carrier with simple constitution without necessitating space by pressing a layer thickness regulating member to the developer carrier with magnetic repulsive force. CONSTITUTION:By turning the developer carrier 20 in a direction a, the developer D in a developer container 22 is fed between the carrier 20 and an applying member 23 to be applied on the carrier 20. The amount and the thickness of the developer D are regulated between them by pressing the developer through the applying member 23 with the magnetic repulsive force between the magnetic field generating member 25 and the layer thickness regulating member 24, so that the developer D is applied in a thin layer state having the desired amount and thickness on the carrier 20. At the same time, the developer D is triboelectrified by the friction between the carrier 20 and the applying member 23 to be charged. Thus, the charged thin layer of the developer is easily formed on the developer carrier with the simple constitution without necessitating the space.
