    • There is disclosed a damping coefficient switching-type hydraulic damper that may automatically switch a damping coefficient without needing supply of energy from the outside at all, and also may always surely exert an energy absorption capacity greater than that of a typical hydraulic damper. While a piston is moving in a direction A, a mechanical drive means composed of a straight gear and a crank mechanism allows an on-off control operation valve, that is, a flow regulating valve to be placed in a closed state, and a damping coefficient is switched to a maximum value Cmax. When a movement of the piston is turned in a direction B at a left-side maximum point of amplitude, the mechanical drive means works to once open the flow regulating valve to perform elimination of a load, so that the damping coefficient is switched to a minimum value (Cmin). When the piston further moves in the direction B, the mechanical drive means works to close the flow regulating valve again, and the damping coefficient is returned to the maximum value (Cmax). Similar working to the above is also applied to a right-side maximum point of amplitude, and seismic response control is attained with repetition of the above operations.
    • 公开了一种阻尼系数切换型液压阻尼器,其可以自动地切换阻尼系数而不需要从外部供应能量,并且还可以始终确保施加比典型的液压阻尼器更大的能量吸收能力。 当活塞沿方向A移动时,由直齿轮和曲柄机构构成的机械驱动装置允许开关控制操作阀,即流量调节阀处于关闭状态,并且阻尼 系数切换到最大值Cmax。 当活塞的运动在左侧最大振幅点处沿方向B转动时,机械驱动装置工作以一次打开流量调节阀以消除负载,使得阻尼系数切换到 最小值(Cmin)。 当活塞进一步沿方向B移动时,机械驱动装置工作以再次关闭流量调节阀,阻尼系数返回到最大值(Cmax)。 与上述类似的工作也适用于右侧最大振幅点,并且通过重复上述操作来获得地震响应控制。

    • It has been difficult to form a high-frequency electronic circuit using a single-crystal dielectric substrate, and down-sizing of high-frequency electronic circuits is also difficult because of necessity of a metal housing. A high-frequency electronic device comprises a single-crystal dielectric substrate provided with a first ground conductor layer and a first wiring conductor layer constituting a high-frequency electronic circuit, a first dielectric substrate provided with a second ground conductor layer, the single-crystal dielectric substrate and the first dielectric substrate being made into contact with each other so that the top faces thereof form substantially the same plane, and a second dielectric substrate provided with a third ground conductor layer, the second dielectric substrate being attached to the top faces of the single-crystal dielectric substrate and the first dielectric substrate, wherein the first ground conductor layer is electrically connected with the second and third ground conductor layers, and the first wiring conductor layer is electrically connected with a second wiring conductor layer formed on the second dielectric substrate, and electrically connected with an external electric circuit via a second through conductor. A high-frequency electronic circuit excellent in characteristics can be obtained, and the down-sizing can be realized by eliminating a metal housing.
