The active seismic isolation system and the active seismic vibration control system have now been focused on because of the recent big earthquake disaster. These active control devices usually regulate actuators within structures by using a computer which processes earthquake input waves monitored with sensors. Although these systems have an advantage that a control program can be designed freely, maintenance of the computer leaves a problem to be solved when a programmer becomes absent. In this study, a novel seismic control device, in which spool valves controlled electrically are replaced with mechanical links directly driven by earthquake waves, is proposed to solve this problem.
