Production manner of the same accelerograph as gravitational force compensating die accelerograph

摘要

(57) Abstract As for this invention, the seismic mass which can receive the power which is pulled up by the acceleration which it should measure it includes (1), as for seismic mass (1) it is concatenated by the base material (2) the mechanical concatenated means which can warp under influencing the aforementioned power by (3), it can provide the detection means which can decide acceleration from the power which is pulled up in seismic mass it regards the accelerograph where compensating means in order to compensate the power which depends on seismic mass with gravitational force are provided. Mechanical concatenated means, one include the part (4 and 5) which forms aforementioned compensating means by causing prestressing which opposes to the power which depends on seismic mass with gravitational force, at least in these mechanical concatenated means. In addition as for this invention, it regards also the manner which produces this kind of accelerograph.
