Please refer to FIG. 4 and FIG. 5, which are a three-dimensional diagram showing how a structure is being fixedly mounted on a conventional raised floor, and a three-dimensional diagram showing how a structure is being fixedly mounted on a raised floor of the present invention. The following description relates to how a device that is mounted on a raised floor of the present invention can react differently from the same device that is otherwise mounted on a conventional raised floor while being pushed by an external force.

In FIG. 4, the fixing of a device 10 to a conventional raised floor 900 can be achieved by fixing the stand 11 of the device 10 to the raised plate 910 by the use of J-bolts 12. On the other hand, although the fixing of a device 10 to a raised floor 100 of the invention can be achieved similar to that disclosed in FIG. 4, but is different in that: there are transfer structures 140 attached to the bottom frame 13 of the device, as shown in FIG. 5. It is noted that the mounting of the device 10 can be performed the same as those shown in FIG. 3, and thus will not be described further therein. As shown in FIG. 5, there are two transfer structures 140 being attached to each of the two short sides L2 while simultaneously there are four transfer structures 140 being attached to each of the two long sides L1.

As shown in FIG. 4 and FIG. 5, the length of the long side L1 of the device 10 is 1690 mm, and the short side L2 thereof is 1250 mm, and its height L3 is 4180 mm, and weigh 950 kg. In addition, there are accelerometers being arranged at position A, B, C and F in respective, so as to be used for measuring gravity acceleration variation happening at those positions.

By exerting a 0.2 g upward pulling force upon the base layers 920 and 120 in respectively, the accelerometers that are arranged at position A, B, C and F are enabled to generating a report relating to the measurement of gravity acceleration variation. Among which, the measurement from the accelerometer at position A is gravity acceleration variation in the vertical direction of the raised plate 910 or 110, while the measurements from the accelerometers at position B, C, and D are the gravity acceleration variation in the X- or Y-direction at different location of the device 10.

Experimentally, there can be seven values obtained respectively at different directions by different accelerometers, which are the six values of gravity acceleration obtained at position B in Y-direction, referring as B-Y, and consequently, at B-X, at B-Y, at C-X, at C-Y, at D-X, and at D-Y, and the one obtained at position A in the vertical direction, as disclosed in the following table:

Accelerometer
position	Conventional raised floor	Raised floor of the invention
A	0.132	0.060
B-X	0.107	0.094
B-Y	0.084	0.059
C-X	0.105	0.091
C-Y	0.081	0.058
D-X	0.110	0.095
D-Y	0.091	0.064

From the above experiment, it is noted that there is a 10%˜40% reduction in gravity acceleration resulting from the raised floor of the present invention, comparing with that of the conventional raised floor. Thus, it is clear that the device 10 that is mounted on the raised floor of the present invention is able to resist vibrations, such as earthquake, better than the one mounted on conventional raised floor.

To sum up, the raise floor of the present invention is advantageous in that: it is designed with enhanced anti-vibration ability for preventing any device disposed thereon from tilting over, and also can be aligned and assembled at will to conform to the size and mounting requirement of a device that is to be disposed thereon, and therefore, the raise floor of the present invention can be for all kinds of machine tables used in photonic and optoelectronic industry, semiconductor industry, LED industry, solar energy industry and even many traditional industries.

With respect to the above description then, it is to be realized that the optimum dimensional relationships for the parts of the invention, to include variations in size, materials, shape, form, function and manner of operation, assembly and use, are deemed readily apparent and obvious to one skilled in the art, and all equivalent relationships to those illustrated in the drawings and described in the specification are intended to be encompassed by the present invention.
