摘要： PURPOSE:To relax an external force operating on a laminate piezoelectric element group and transmit fine vibration linearly to the outside by using both a parallel elastic body and a serial elastic body for the laminate piezoelectric element group in combination. CONSTITUTION:When a voltage having a desired waveform is applied from a power source, the laminate piezoelectric element group 4 is repeatedly strained in its lamination direction. This element group 4 is positioned between the bottom part 11 of an external cylinder 2 and the bottom part 12 of an internal cylinder 3 and fixed to both the bottom parts 11 and 12 to generate the fine vibration in the vertical direction along the axial direction. The parallel elastic body 5 is positioned between the flanks of the external cylinder 2 and internal cylinder 3, and flexible axially but very rigid in other directions to relative motion between the internal and external cylinders with many annular grooves 13 provided in the inner peripheral surface of a cylindrical body formed of an elastic member. The serial elastic body 6 has plates 15a and 15b fixed on both end surface of a columnar body 14 made of an elastic body to absorb axial high-frequency vibration, thereby insulating the element group 4. Consequently, no play is generated between the internal and external cylinders and mutual operations never interfere with each other.

摘要： PROBLEM TO BE SOLVED: To decrease the number of piezoelectric actuators and obtain damping performance by making the number of piezoelectric actuators arranged at the outer edge section of a column that faces the outside of a building in the control direction of the building larger than that of those arranged at the inner edge section of the column that faces the inside of the building. SOLUTION: Axial force and bending moment control is carried out in each column member and piezoelectric actuators are installed only at the outer edge section of a column. Therefore, even if same phase or opposite phase control voltage is applied to both inner edge and outer edge, piezoelectric actuator count components that contribute to control will increase. In addition, of given piezoelectric actuators, the number of piezoelectric actuators which permit to obtain the best damping performance and realize the same damping performance is minimized. Therefore, the number of piezoelectric actuators installed is cut while maintaining damping performance. Therefore, labor needed for installing piezoelectric actuators can be reduced, and load of a piezoelectric actuator controller can be lowered.

摘要： PURPOSE:To suppress vibration soundly, regardless of the scale of vibration, by controlling a variable damping force damper at a real time by means of a control device which supports a structure movably in the vibrating direction and works with detected signals of a sensor. CONSTITUTION:A structure 1 is supported on a basement 6 through a laminated rubber pillar 2 which is formed by steel sheets and rubber sheets laminated in turn. And a variable damping force oil damper 3 is installed between the structure 1 and the basement 6 with pin-hinge mechanisms 7, 9. And a sensor 4 which detects vibration is arranged and at the same time, that detected signal is converted into an optimum damping responding output signal in a control device 5 and the output signal actively controls the variable damping force oil damper 3 at a real time and changes responding characteristics of the damp er most adequately. By this process, the vibration of structure can be soundly suppressed regardless of the scale of the vibration.

摘要： PROBLEM TO BE SOLVED: To apply no bending to a base isolation device to the utmost by connecting an upper face plate of the base isolation device fixed to a foundation structure and a flange plate fitted to the lower base of a base isolation structure to each other to roll. SOLUTION: When bending deformation is caused in a post 11 of a base isolation structure to apply compressive force and tensile force to a base isolation device 1, a flange plate 4 fitted to a lower base part of the post 11 is caused to rotate, the outer peripheral part of the flange plate 4 causes rolling along the spherical surface or polygonal surface to vary vertically, and twelve discoidal springs 7 are elongated and contracted to follow, thereby absorbing and lightening the vertical displacement, so that excessive additional axial force is not applied to a bolt 6 and bending can be prevented from being transmitted to the base isolation device to the utmost. A dowel 3 is integrally provided in the lower surface of the flange plate 4, and a slit 5 fitted to the dowel 3 is provided in an upper face plate 2 to similarly execute the above. Thus, a natural function of the base isolation device can be permanently maintained so as to realize base isolation and differential settlement measures in an intermediate layer base isolation and the post head.

摘要： PROBLEM TO BE SOLVED: To provide a radio wave-absorbing reactive material which is easily subjected to processing such as precise adhesion high in heat-resistance, molding, repair, etc., in technical areas of machining and building construction. SOLUTION: The material is prepared by dispersing a granular or fibrous radio wave-absorbing material such as carbon, metal, ferrite, etc., which transduces radio wave energy into heat, in a resin material matrix which cures or shrinks through heating, such as a thermoplastic resin, etc., which induces crosslinking reaction by heat. Radio waves are applied to this radio wave- absorbing reactive material or molded article therefrom to induce curing or shrinking for a desirable processing.

摘要： PROBLEM TO BE SOLVED: To exhibit the stopper function during a large earthquake by setting a pressing force in an inoperable mode in a vibration stroke range allowable to a vibrating body in a overlapped part of a sliding member, and giving a pressing force of the magnitude to suppress the vibration in a limiting part of the vibration stroke. SOLUTION: An overlapped part G of both sliding members A, B is in a condition where a pressing force is inoperable so as to generate little friction force in a range a-a of the vibration stroke allowable for a vibrating body. The pressing force of the magnitude to stop the vibration of the vibrating body 1 is given only in a limiting part 1-b of the vibration stroke. During an earthquake in which the vibrating body is vibrated in a range of the allowable stroke, the vibration control effect of a vibration control structure, or the base isolation effect of a base isolation structure is not impeded, while during a large earthquake in which the vibrating body can be in an excessive vibration stroke, an effective stopper function is exhibited and moreover can be carried out in an economical manner.
