Filed: 1988-11-17
Abstract: PURPOSE:To easily and freely obtain a required sweep signal by performing success control by calculating a sampling period to read out sampling data from a read-only memory based on a sweep start frequency, a sweep completion frequency, and sweep time designated at a processing part. CONSTITUTION:The processing part 1, when the sweep start frequency, the sweep completion frequency, and the sweep time being designated from the outside, calculates the sampling period required for the generation of a sweep signal frequency that changes successively or by stages from the sweep start frequency to the sweep completion frequency in one sweep period i.e., the access cycle of a ROM 2.

Title: Vibration isolating supporting device for apparatus
Inventor: MIZUHAYA JIYUN
IPC: F16F15/03
Filed: 1997-10-23
Abstract: PROBLEM TO BE SOLVED: To prevent occurrence of resonance, and also block occurrence of excessive relative displacement, by changing the rigidity of a super magnetostrictive member interposed between an apparatus and a structural body. SOLUTION: A structural body 1 mainly vibrated in a vertical direction supports an apparatus 2 such as an engine, an electric motor and a communication apparatus through supporting parts 3a, 3b comprising a super magnetostrictive member. Coils 4a, 4b are wound around these supporting parts 3a, 3b, and when distortion is generated in the super magnetostrictive member, a circumferential magnetic field is changed and induced electromotive force is generated in the coils 4a, 4b. Namely, when switches 5a, 5b are closed, the magnetic field is generated and the elastic modulus of the supporting parts 3a, 3b is changed. Therefore, if supporting rigidity is enhanced when large acceleration G1 is applied to the structural body 1, the change of the supporting parts 3a, 3b is diminished therefore, the apparatus 2 and the structural body 1 can be prevented from being collided with each other.  Also, even though the frequency of the vibration acceleration G1 of the structural body 1 approaches resonance frequency, when the supporting rigidity of the supporting parts 3a, 3b is changed, natural frequency is changed so as to avoid resonance.
