Title: Lens actuator
Inventor: HASHIMOTO MASANOBU
IPC: G11B7/09
Filed: 1987-11-16
Abstract: PURPOSE:To raise the resonance frequency of torsional oscillation of a movable part and to perform an operation at high speed by using the movable part on which a condenser lens having a small moment of inertia is mounted, leaf springs provided with flanges in centers, and a binding spring which couples right and left leaf springs. CONSTITUTION:The moment of inertia of a movable part 2 around the longitudinal direction intersecting orthogonally with the focusing direction and the tracking direction of the movable part 2 which determines the resonance frequency of torsional oscillation of the movable part 2 is reduced, and the rolling of the movable part 2 caused by the bending oscillation of leaf springs 3a, 3b, 3a', and 3b' supporting the mobile part is suppressed by a binding spring 14 coupling the movable part 2 and the junction part of leaf springs 3. Consequently, the movement of inertia around the longitudinal direction is set to a small value, and high rigidity is given to plural leaf springs 3a, 3b, 3a', and 3b' provided between the movable part 2 and an arm 4 by flanges. Oscillation due to rolling of the movable part 2 is suppressed by the elasticity of the binding spring 14 coupling leaf springs 3. Thus, a lens actuator is obtained which is light-weight and high-rigidity and has the high resonance frequency of torsional oscillation, and the quick operation in the tracking direction is realized.

The greater part of the gases enter a first absorption stage 19 through an electrostatic precipitator 14. The acidic gases, such as NO2 , SO2 , SO3 and HCl, are scrubbed by the aq. ammonium salt-contg. soln. in this stage. The molar ratio of the SO2 to the NO2 is then adjusted to 0.01 to 0.5 in a second absorption stage 25. NH3 water is added to the gases from a conduit 26 to get rid of the NO2 and acidic components. The salt soln. obtd. in the absorption stages 19, 25 are both supplied to a neutral vessel 30 where the NH3 water is added thereto from a pipe 31. These solns. are sent to a drying device 6 where the solns. are evaporated and dried by part of the exhaust gases.  The pelletized salts are separated in a separator 8.
