Abstract: Disclosed is an electroless nickel plating bath not containing harmful metal species. In the electroless nickel plating bath, there are contained at least an iron ion source and an iodide ion source. With the use of the electroless nickel plating bath containing at least the iron ion source and the iodide ion source, it is possible to suppress decomposition of the plating bath without using harmful metal species to stabilize the plating bath.

Abstract: A weight is disposed in an arbitrary story of a structure so as to be movable relative to a direction of motion of the structure. Rotary members are supported in the weight. Rigid members meshing with gears provided on each rotary member are slidably fitted in the weight. These rigid members are respectively coupled to a ceiling and a floor via coupling members. The rotary members and the rigid members are disposed on the weight in correspondence with two horizontal directions. As a result, a horizontal motion of the floor of the structure is temporarily converted into a rotational motion by the rotary members, and is then converted into a horizontal motion so as to be transmitted to the ceiling. At this time, since the rotary members are pivotally supported in the weight, the weight can be moved in the opposite direction to that of the floor without undergoing an arcuate motion, thereby exhibiting the effect of reducing an input of vibration.

Abstract: A vibration proofing/suppressing system including a first rigid member extending and translatable in a first direction, a second rigid member extending parallel to the first rigid member and translatable in the first direction relative to the first member, a third rigid member interposed between the first and second rigid member, and a fourth member interposed between the first and second rigid members. Guide means are interposed between the first and third and fourth members and the second and third and fourth members for guiding translation of the third and fourth members along the direction of relative movement between the first and second members. At least one first lever means connects the first member to the fourth member, the at least one first lever means being pivotally connected to a first point on the third member such that the at least one first lever means is swingable about the first point.
