Patent number: 6123313Abstract: A seismic isolation apparatus is structured such that a pair of seismic isolation mechanisms are formed each having a pair of upper and lower clamping members formed in the shape of a rectangular frame, wherein upper and lower roller guide surfaces, in each of which a longitudinal central portion is formed as a concavely arcuate curved surface and portions respectively extending therefrom are formed as convexly arcuate curved surfaces, are formed on the four sides of the upper and lower clamping members, and wherein rollers each having a circular cross section are respectively interposed between the upper and lower roller guide surfaces. The pair of seismic isolation mechanisms are installed by being superposed on top of each other such that the rolling directions of the rollers in the two seismic isolation mechanisms are perpendicular to each other.Type: GrantFiled: June 22, 1998Date of Patent: September 26, 2000Assignees: Okumura Corporation, Oiles CorporationInventors: Susumu Otsuka, Kunio Hayakawa, Ikuo Shimoda, Kiyoharu Suzuki, Masami Mochimaru, Mitsuru Miyazaki

Patent number: 5544452Abstract: A passive vibration-damping unit in which movable upper members with a weight mounted thereon are superposed on fixed lower members with roller members interposed therebetween is installed in a highest story of a high-rise building. An active vibration-damping unit for actively causing the movable upper members of the passive vibration-damping unit to move in a shaking manner by means of a servo motor is incorporated in the passive vibration-damping unit. When the vibration of the building has occurred, the weight is allowed to move forcibly in the vibration-damping direction by means of the active vibration-damping unit. When the vibration has reached a limit value of the relative displacement of the active vibration-damping unit or a limit value of the torque of the servo motor, only the operation of the passive vibration-damping unit is continued. When the vibration has subsided to a certain extent, the active vibration-damping unit is operated again.Type: GrantFiled: July 5, 1994Date of Patent: August 13, 1996Assignees: Oiles Corporation, Okumura CorporationInventors: Takafumi Fujita, Ikuo Shimoda, Masami Mochimaru, Susumu Otsuka, Nobuyasu Kawai, Kurimoto Kurimoto, Kanemasa Inaba

Patent number: 5103943Abstract: A vibration damper for damping roll vibration of a power unit mounted on a vehicle body. The vibration damper is composed of a disc plate fixedly connected to the power unit in a manner that the axis of the disc plate is generally parallel with a roll axis of the power unit. The disc plate is sealingly disposed in a chamber formed in a generally circular casing which is coaxial with the disc plate. A viscous fluid is filled in a space defined between the disc plate and inner surface of the casing. The casing is formed of a plastic which has a higher linear expansion coefficient than a metal forming the disc plate, thereby allowing the space filled with the viscous fluid to expand along with thermal expansion of the viscous fluid.Type: GrantFiled: December 3, 1990Date of Patent: April 14, 1992Assignees: Nissan Motor Co., Ltd., Oiles CorporationInventors: Takanobu Ide, Masamitsu Kojima, Masura Iwakura, Masami Mochimaru

Patent number: 5037058Abstract: A damper used to damp roll vibration of an automotive power unit includes housing in which a disc is immersed in a highly viscous liquid, and a linkage which has universal joints formed at each end thereof. The linkage induces relative rotation between the housing and the disc. A resilient vibration attenuating arrangement is included in one or both of the universal joints for insulating the vehicle chassis from vibration which tends to be freely transmitted through the damper per se and cause cabin reverberation noise.Type: GrantFiled: December 1, 1989Date of Patent: August 6, 1991Assignees: Nissan Motor Co., Ltd., Oiles CorporationInventors: Masamitsu Kojima, Masami Mochimaru, Ikuo Shimoda, Masaru Iwakura, Takanobu Ide
