Abstract: ABSTRACT    A control system for suspension cylinders mounted on a vehicle is capable of preventing the vehicle body from rolling without any delay in response when the vehicle is turning.  It also is capable of preventing the vehicle body from rolling even when it is turning along a circular arc path having a fixed diameter.  The suspension cylinders are mounted between the vehicle body and the front and rear wheels on the left and right sides.  Fluid pressure sensors detect the internal fluid pressure in each of the suspen-sion cylinders.  A steering angle sensor detects the steer-ing angle of a steering wheel mounted on the vehicle.  A controller receives signals from the sensors and transmits a signal for increasing the damping forces provided by the suspension cylinders in accordance with the steering angular velocity transmitted by the steering angle sensor until the difference between the fluid pressure in the left and right suspension cylinders for the front and rear wheels becomes less than a predetermined value.

Abstract: Abstract The present invention provides a direct current restorer applied to a pedestal  clamp circuit  of  a television receiver or the like,   in which an input video signal is compared with a pedestal level setting reference signal for every pedestal period, and, based on difference between the pedestal level of the input video signal and the level of the reference signal, the direct current level of the input video signal is shifted.  In this direct current restorer,  a direct current according to the level variation of the ref-erence signal may be superposed on the input video signal so that the direct current level of the input video  signal  is  corrected  according to  the  level variation of the reference signal.  Accordingly,  when adjusting the pedestal level  or achieving  a liquid crystal display in which the polarity of the input video signal is periodically inverted,  a direct cur-rent according to the level variation of the reference signal may be superposed on the input video signal.          Thus, the pedestal level of the input video signal may quickly follow the level variation of the reference signal and may be controlled to the level of the ref-erence signal with no influence exerted onto the com-parison in level of the input video signal with the reference siqnal.  Accordingly,  when this direct cur-rent restorer is applied to, for example, a drive cir-cuit  for  a  liquid crystal  panel  such  as  a  liquid crystal television receiver or the like in which the input video signal is periodically changed in polari ty,   a stable direct current restoration may be a-chieved.
