Title: Dielectric polarization type speed meter
Inventor: TORIGOE IPPEI
IPC: G01P5/18
Filed: 1996-10-03
Abstract: PROBLEM TO BE SOLVED: To provide a speed meter which can measure the moving speed of a body in noncontact, and is simple in structure and low in manufacturing cost by applying an electric field to the body to induce a dielectric polarization, and detecting the degree of the movement of the dielectric polarization which moves with its shape kept during the movement of the body. SOLUTION: A body 6 is sandwichedly held between electrodes 1 and moves in an electric field formed of the electrodes 1. A current detector 3 detects a current flowing in a capacitor composed of the electrode 1 and the body 6. A signal processor 4 computes the moving speed of the body from an output signal given by the current detector 3. When the electric field is applied to the body 6, a dielectric polarization is induced in the body. As the body 6 moves, an external electric field felt by the body 6 changes, but a finite relaxation time exists in the dielectric polarization, and that in the body can not momentarily follow the external electric field, and when it is observed at minute time intervals, it moves as a state at a previous time is almost kept. Thus the moving speed of the body 6 can be measured by inducing the dielectric polarization and detecting its moving degree.
