Title: Re-dispersion of electric field arrangeable particle
Inventor: FURUICHI KENJI
IPC: G02F1/19
Filed: 1996-02-26
Abstract: PROBLEM TO BE SOLVED: To make it possible to rapidly re-disperse EA particles and to exactly attain a light shielding state by impressing a first voltage to generate an electric field arrangement effect between transparent electrode plates to increase the quantity of transmitted light and impressing a second voltage to generate an electrophoresis effect between these transparent electrode plates to decrease the quantity of transmission. SOLUTION: When the first voltage is impressed between the electrodes 5 and 7, the EA particles 11 are perpendicularly arranged between the transparent electrode layers 53 and 73 by the EA effect and chain bodies are formed. Namely, a light controller section 1 attains the light transmission state as the attenuation to the incident light quantity decreases. On the other hand, the EA particles 11 executes electrophoresis and eventually stick to the one-side surfaces of the transparent electrode layers 53, 73 when the second voltage is impressed between the transparent electrodes 5 and 7. Namely, the light controller section 1 attains the light shielding state as the attenuation to the incident light quantity increases in the state that the second voltage is impressed thereon.  The light shielding state is exactly and rapidly attained by impressing the second voltage different from the first voltage between the electrodes.

Filed: 1985-02-27
Abstract: PURPOSE:To improve the target following-up characteristic and the disturbance suppressing characteristic by providing a lead-delay operating means for a target value. CONSTITUTION:A measured value PV is subtracted from the output signal, which is obtained by inputting a target value SV to a lead/delay operating means 31 and operating it there, by a subtracting means 32 to take out a deviation DELTAPV, and this deviation DELTAPV is introduced to a PI(D) operating means 34, and the output signal obtained by PI(D) regulating operation is applied to a controlled system 7 as an operation signal MV, and the controlled system 7 is so controlled that the measured value PV coincides with the target value SV. An optimum PI parameter of disturbance suppression is set as the PI parameter of PI regulation, and a reset time is set as the time constant of the lead/ delay operating means 31. Thus, this device is most suitable for the variation of disturbance and the change of the target value, and a PI control system having two degrees of freedom is attained. A coefficient alpha is varied to improve the following-up characteristic to the change of the target value without changing the characteristic to disturbance.
