<P>PROBLEM TO BE SOLVED: To solve the problem which controls very accurately so that the position of a shock absorbing desk gets into a horizontal position. <P>SOLUTION: The detected signal A<SB>X1</SB>, A<SB>X2</SB>, A<SB>y1</SB>of the second acceleration sensor 39<SB>X1</SB>, 39<SB>X2</SB>, 39<SB>y1</SB>is transmitted and the amendment means 44A is provided with an operation means 44 to calculate the movement mode acceleration M<SB>XA</SB>, M<SB>yA</SB>, Mθ<SB>ZA</SB>. When the shock absorbing desk 13 is moved to the rotating directions θx and θy of two horizontal axes, the movement mode acceleration M<SB>XA</SB>, M<SB>yA</SB>, Mθ<SB>ZA</SB>is corrected based on the movement mode displacement Mθ<SB>XD</SB>, Mθ<SB>yD</SB>and the movement mode acceleration Mθ<SB>XA</SB>, Mθ<SB>yA</SB>by the amendment means 44A. <P>COPYRIGHT: (C)2008,JPO&INPIT |
