Abstract: PURPOSE: To control the cataphoresis of a particle in gel and to adjust the shape and orientation of electric field by identifying the particle by operating the electric field generated by an electrode arranged along a two-dimensional close-down contour line to the particle in a proper medium. CONSTITUTION: A net resistance between electrodes located at corners is switched along with the orientation of an electric field, thus making a potential suitable for the orientation. For that purpose, six resistors are added in parallel between six pairs of electrodes located at the corners. In the case of four pairs of electrodes, resistors R25-R28 are added in series with diodes D5, D8, D17, and D20. A potential difference between electrode pairs 4 and 5, 8 and 9, 16 and 17, and 20 and 21 changes according to the orientation of the electric field due to this change. Then, when A+electrode and A-electrode drive the electric field, the potential difference between a pair of electrodes 4 and 5 and between a pair of electrodes 20 and 21 decreases to the half of the potential difference between a pair of electrodes 8 and 9 and between a pair of electrodes 16 and 17.

Filed: 1991-08-01
Abstract: PURPOSE:To suppress and reduce the slip caused by the shortage of the pushing force on the side where no pushing force generating mechanism is arranged and prevent the slip in a double cavity toroidal CVT. CONSTITUTION:A toroidal continuously variable transmission is provided with two sets of toroidal transmission mechanisms, a loading cam mechanism, and a hydraulic servo device as an actuator of the respective power rollers (18c,20c). When the loading cam is arranged on the forward transmission mechanism side, the relationship phiD1>phiD2 shall be made so that the diameter phiD2 of the cylinder 100R in the rear side where no cam is provided may be smaller than the diameter phiD1 of the hydraulic piston cylinder 100F in the forward side. The relationship of phiD1>phiD2 realizes the torque distribution proportional to the pushing force, and reduces the slip of the toroidal transmission mechanism in the rear side. The torque distribution may be realized by making the hydraulic pressure on the rear side smaller than that on the forward side regarding the hydraulic pressure difference between both piston side oil chambers 101,102. In this case, the cylinder diameter may be the same.
