Abstract: A method for producing a catalyst supporting a metal or an alloy on a support, including: independently controlling a temperature of a first supercritical fluid to be first temperature, the first supercritical fluid containing a precursor of the metal or precursor of the alloy that is dissolved in a supercritical fluid; independently controlling a temperature of the support to be a second temperature higher than the temperature of the first supercritical fluid; and supplying the first supercritical fluid controlled to the first temperature to the support, to cause the metal or the alloy to be supported on the support.

Abstract: There is provided an audio/display apparatus that provides a large display and high-power output of an audio signal and is acceptable as one of the room furnishings, which is installed in a most noticeable position in the room. It includes an upper foreign body detecting mechanism provided along the entire top portion of an audio unit, opposite to at least a display unit, to detect a foreign body lodged in a clearance defined between the audio unit and display unit, and a lower foreign body detecting mechanism provided along the entire bottom portion of the audio unit to detect a foreign object caught at the bottom portion of the audio unit having moved to a first position.

Abstract: A floor vibration-damping apparatus damps a horizontal vibration of a floor based on an earthquake or the like. This apparatus comprises a movable supporting portion for supporting a floor structure with being free to move horizontally, and a damper working portion provided between said floor structure and a fixed floor.

Abstract: A floor vibration-damping apparatus damps a horizontal vibration of a floor based on an earthquake or the like. This apparatus comprises a movable supporting portion for supporting a floor with being free to move horizontally, and a damper working portion made by a combination of a viscous damper fixed to a restricted position of the floor and a plurality of spring mechanisms positioned radiately with respect to the restricted position.

Abstract: A vibration-damping floor is supported by one ends of flexible coupling members, such as chains or ropes whose the other ends are connected through guide sprockets and movable spring frames to tension springs set horizontally under the floor. A vertical vibration for the floor is absorbed by the springs.

Abstract: A method of applying a floor vibration-damping work and a floor vibration-damping device supporting horizontally displaceably respective supports points of the floor structure on a fixed floor and supporting the other respective points of said floor structure on the fixed floor with a position restoring function relative to the horizontal displacement, as well as a triggering function and a damping function during said displacement.
