Abstract: front page image
(EN)[PROBLEMS] To enhance output and S/N ratio by regulating the relative movement of a magnet and a coil to within an optimal range and to enhance precision and reliability of a vibration measuring instrument. [MEANS FOR SOLVING PROBLEMS] Amplitude of vibration of a magnet (26) is regulated by stoppers (14, 22) and the lower end face of the magnet (26) does not move beyond the center and the upper end face of a coil (13). The magnet (26) vibrates such that the lower end face thereof reciprocates between the center and the upper end face of the coil (13) at all times, and an accurate cosine wave is outputted from the coil (13) at all times.
(FR)L'invention concerne l'amélioration du rendement et du rapport S/N par régulation du mouvement relatif d'un aimant et d'une bobine dans un intervalle optimal, ainsi que l'amélioration de la précision et de la fiabilité d'un instrument de mesure de vibration. L'amplitude de vibration d'un aimant (26) est régulée par des tampons (14, 22) et la face d'extrémité inférieure de l'aimant (26) ne se déplace pas au-delà du centre et de la face d'extrémité supérieure d'une bobine (13). L'aimant (26) vibre de façon que sa face d'extrémité inférieure effectue constamment un mouvement de va-et-vient entre le centre et la face d'extrémité supérieure de la bobine (13), et une onde cosinusoïdale exacte est constamment produite par la bobine (13).
(JA)【課題】磁石とコイルとの相対移動を最適な範囲に規制することにより、出力およびS/N比を大きくすることができ、振動計測装置の精度と信頼性を向上させる。 【解決手段】ストッパ14,22により磁石26の振動の振幅が規制され、磁石26の下端面がコイル13の中心と上端面とを超えることがない。このため、磁石26は、常にその下端面がコイル13の中心と上端面との間を往復するように振動し、コイル13からは正確な余弦波が常に出力される。
