Patent number: 5234507Abstract: An anti-oxidation agent for preventing oxidation of a stainless steel strip during continuous annealing comprising a colloidal inorganic substance which can be crystallized at a temperature not higher than 1300.degree. C. at least one compound having a melting point not higher than 1300.degree. C., selected from the group consisting of silicates, borates and phosphates, a dispersion agent, and the balance substantially water. The anti-oxidation agent is applied to the surface of the stainless steel strip. During the annealing, the anti-oxidation agent enhances the heat absorption so that the stainless steel strip temperature is elevated to the annealing temperature in a short time. The anti-oxidation agent on the strip surface forms a film of a fine structure which keeps the strip surface away from oxidizing components of the annealing atmosphere so as to suppress generation of oxide scale. The film is easily separated due to thermal contraction in the course of the cooling after the annealing.Type: GrantFiled: July 9, 1991Date of Patent: August 10, 1993Assignee: Kawasaki Steel CorporationInventors: Kuniaki Sato, Genichi Ishibashi, Yasuhiro Katsuki, Hiroyuki Kaito, Hisatomi Muraki, Yoshiharu Yamaguchi

Patent number: 5189851Abstract: A structure having a movable dome-type roof including a plurality of independently movable shell sections which nest one beneath the other. A frame superstructure is arched over the dome to support the upper ends of the shell sections. The lower edges of the shell sections are mounted on self-powered carriages and are independently shiftable about a circular base of the structure. By selectively shifting individual shell sections, the dome may be contracted or expanded as desired. The superstructure may be mounted on a circular track or on a pair of linear tracks to expedite the opening and closing of the dome.Type: GrantFiled: September 12, 1991Date of Patent: March 2, 1993Assignee: Kajima CorporationInventors: Yukihiro Omika, Kuniaki Sato, Eiji Matsushita, Kazuo Kojima, Tsutomu Kumazawa, Yasuo Ogawa

Patent number: 5131126Abstract: A descaling method for removing oxide scale from a hot-rolled stainless steel strip. A solution of an alkaline earth metal chloride is applied to the surface of the oxide scale layer formed on the hot-rolled stainless steel strip, and the solution is allowed to penetrate into the oxide scale layer. In a subsequent annealing, the solution is heated and dehydrated to become solid matter and the dehydrated matter is melted and diffused into the oxide scale layer to soften the oxide scale layer. The oxide scale layer is then removed by a simple mechanical descaling by, for example, grinding brushes with or without a subsequent chemical descaling by a weak acid solution.Type: GrantFiled: April 19, 1991Date of Patent: July 21, 1992Assignee: Kawasaki Steel CorporationInventors: Yasuhiro Katsuki, Kuniaki Sato, Genichi Ishibashi, Hiroyuki Kaito

Patent number: 5065555Abstract: An elasto-plastic damper is adapted to be used in a structure, such as a building and other facilities, for absorbing vibration energy created by earthquake tremors and other ground vibrations. The damper is a centrally bulged and generally cone-shaped hollow body of revolution so that its section modulus changes substantially porportional to a bending moment created in the damper body due to horizontal stresses, thus permitting a maximum degree of deformability. This elasto-plastic damper is compact in size and demonstrates a high degree of vibrational energy absorbability.Type: GrantFiled: November 21, 1989Date of Patent: November 19, 1991Assignee: Kajima CorporationInventors: Takuji Kobori, Shunichi Yamada, Shigeru Ban, Koji Ishii, Isao Nishimura, Masatoshi Ishida, Kuniaki Sato, Yasuo Takenaka, Shozo Maeda, Jun Tagami
