Title: Method and circuit for exciting and monitoring piezoelectricmotor in step mode
Inventor: ROORAN RUCHIEERU
IPC: H01L41/04
Filed: 1996-11-15
Abstract: PROBLEM TO BE SOLVED: To easily and efficiently adjust the exciting frequency by comparing the step duration of a piezoelectric motor with a limit duration of a step to be appropriately rotated. SOLUTION: In a control circuit 2 of a piezoelectric motor M1 , a programmable oscillator 17 outputs the alternating frequency signal corresponding to the desirable exciting frequency fE, and excites the motor M1 for the appropriate operation at a frequency near the resonance frequency fR through a wire 61 and an output means 3. Since the resonance frequency fR is fluctuated by the influence of the effect of heat, it is necessary to adjust the frequency fE, and the circuit 2 measures the step duration t1 of the motor M1 at the frequency fE with a spring plate 50 and a rotor R1 . This step duration ti is compared with a limit duration t0 of the appropriate rotation of the motor M1 at the frequency fR, and in the case where the step duration ti exceeds the limit duration t0 , a duration ti +1 at a new frequency fE (fE+Δf) is measured.  In the case where the step continuity period ti continuously exceeds the limit duration t0 , the new frequency fE is quickly converged in the opposite direction, namely, to the frequency fE-Δf. Frequency fE is thereby easily and efficiently adjusted.

Title: Orientation measuring device and orientation measuring method for fiber
Inventor: URAGAMI AKIRA
IPC: D01F6/46
Filed: 1998-11-11
Abstract: PROBLEM TO BE SOLVED: To precisely measure the orientation at a low cost by emitting white light to a fiber to make an interference color revealed, and analyzing the interference fringe generated by performing a continuous compensation by a rotary polarizing plate to determine the double refractive index. SOLUTION: The periphery of a fiber is filled with a liquid having a refractive index substantially equal to the thickness directional refractive index of the fiber, and white light is emitted to a synthetic fiber filament F by a light source mechanism 2. A plurality of wavelength plates having different optical path compensation values is used to compensate the optical path difference of the fiber. When the interference color is observed by an observation mechanism 3, and the optical path compensation value of the wavelength plate is increased, the interference color gradually transfers to the lower-order side. The image of the revealed interference fringe is analyzed by an image processing device 36, whereby a double refractive index is determined from the expression ΔN=nλ/SQR(D2-W2).  According to this, with respect to a general circular sectional fiber, the orientation can be measured only by the regulation by the wavelength plate.
