Recently, buildings using seismic isolation system (SIS) become general to improve seismic safety in Japan. However, the SIS general is chiefly effective only to the hori [...]

Many base-isolated buildings have been constructed using passive isolation systems with the purpose of reducing response accelerations of superstructures during earthquak [...]

As the semiconductor processing technology keeps evolving, the demand for vibration-free environment of semiconductor manufacturing facilities keeps becoming severe. We d [...]

This paper describes a seismic isolation system for monocrystal pullers. In a monocrystal puller, a monocrystal is suspended by a wire through an extremely narrow neck, a [...]

A lot of researches on the seismic vibration control system show that they have effect on mitigating seismic damage. Most researches on structures with damper devices sub [...]
