Abstract: PURPOSE:To obtain both anti-lock and traction control functions with a simple structure by controlling the oil pressure feed to the first control hydraulic chamber of driving wheel first control valve means and the second control hydraulic chamber of driving wheel second control valve means. CONSTITUTION:No oil pressure is applied from an oil pressure feed source 4 to first and second control hydraulic chambers 22 and 37 of first and second control valve means 1FL, 1FR, 2FL and 2FR for driving wheels, the first and second input chambers 21 and 36 are communicated to the first and second output chambers 20 and 35, when a brake pedal P is depressed, oil pressure is applied from a master cylinder M to a brake chamber B. When the oil pressure of the second control hydraulic chamber 37 is increased while the oil pressure of the first control hydraulic chamber 22 is kept low, the volume of the first output chamber 20 is increased, and the anti-look control is performed. When the hydraulic relation is reversed, the volume of the second output chamber 35 is decreased, and the traction control is performed. Both anti-lock control and traction control functions can be obtained with a simple structure accordingly.

IPC: H04N1/113
Filed: 1990-01-31
Abstract: PURPOSE:To easily and surely allow a desired simple harmonic motion by subjecting a cylinder lens for correction disposed between a light source device and a rotary polyhedral mirror to the simple harmonic motion in an optical axis direction by a lamination type piezoelectric actuator and a displacement magnifying mechanism. CONSTITUTION:The lamination type piezoelectric actuator is driven via a switching circuit which causes the electric discharge of the lamination type piezoelectric actuator 12 when a switching pulse is low. While the sinusoidal voltage of a desired frequency (f)(the frequency of the simple harmonic motion required for the cylinder lens 2) is inputted to an input terminal for driving the actuator, a pulse square wave of a period T (=1/f) is impressed as a switching pulse to the switching circuit. The time 2DELTAT to satisfy the condition 2DELTAT>=t with respect to the discharge time(t) is set around the time when the sinusoidal voltage attains 0 and the switching pulse is set at the low level so as to coincide with this discharge period. The cylinder lens 2 is thus subjected to the good simple harmonic motion according to the curvature of field of the imaging optical system.
