Explain that the structure of the moon foot deceleration state is fixed so that a vibration absorbing member is fixed between the two phases, the rain and the time support K members. This is similar to the structure of a known shock absorber (Zhenchen early 7L). The sandwich structure including a single group of two supporting members and a vibration absorbing member can be constructed by two or more groups. The supporting member must be made of a material with a slight transmission rate to determine the entire shock absorber: a slight transmission rate. Furthermore, when mounted on a structure or the like, this vibration damping does not adversely affect the strength of the structure or the like and the properties of the shock absorber ′, so it is preferably made of a concrete material. Preferred materials for the support member: glass, plastic (such as acrylic plate), and so on. The slight transmission rate of the support member can be arbitrarily changed according to the components or the required appearance of the shock absorber. The support members with different transmission rates can use about 100% transmission rate from transparent glass to non-transparent but slight transmission rate. Broken glass or matte surface. In addition, various shapes and sizes of supporting members that match the shape of the shock absorber can be adopted depending on whether the shock absorber is a parallelogram, a plate, a hollow cylinder or a solid cylinder. When the shock absorber is a parallelogram or a plate, In the example, a plate-shaped support member can be used 'otherwise' in the case of a solid or hollow cylindrical shock absorber, and a hollow or ring-shaped support member can be used. The vibration absorbing member is made of viscoelastic or viscous material A. It has the effect of using elastic deformation to reduce the vertical or horizontal vibration and swing applied to the shock absorber due to wind or earthquake. This viscoelastic or viscous material also needs A material with a slight transmission rate to determine the slight transmission rate of the entire shock absorber. When measured during a cycle, the viscoelastic material needs to have a shear strain of at least 10% 2 and a loss tangent of at least G.3, especially acetic acid materials such as copolymers of propionic acid and propylammonium, silicon materials For example, methyl ethyl fluorinated silicone, imide ester material examples, ㈣ imine vinegar or polyimide, ㈣ 缔 缔 缔 缔 淀 淀 材 肖 丁 丁 丁 丁 丁 丁 肖 肖 肖 肖 肖 肖. Generally available products such as VEM110, Lu, 112 or 113 of Sumitom3M can be used as viscoelastic materials. On the other hand, a better viscous material has a Brookfield rotary viscosity meter 7 Rotor has a viscosity of more than 10 poise, and especially includes an acrylic fluid, a silicon fluid, an imide fluid, a polyvinyl chloride fluid, a butane fluid or a butyl fluid. Figure j reveals that the vibration damping of the present invention is a preferred embodiment. The shock absorber 8 is provided with plate-shaped supporting members 9a, 9b and a vibration absorbing member 10 and a vibration absorbing member 10 sandwiched between the plate-shaped members. It is made of a solid viscoelastic material. The viscoelastic material is viscous and therefore can produce sufficient adhesive force by contacting the support member. However, in some examples, the shock absorbing member and the supporting member may be bonded to each other using a transparent adhesive, such as polyethylene, imide, or cyanopropionate. Similarly, as shown in FIG. 4, a preferred shock absorber includes three 514692 A7 B7 5.
