Abstract: PURPOSE:To detect a tracking error signal having a good S/N with high using efficiency of light and without using a mechanical modulation means for an optical recording/reproduing device of a 2-beam system using the separation of polarization, by using a detector to detect a tracking error in terms of AC. CONSTITUTION:A polarization modulator 6 applies minute vibrations of a0sinomega0t (a0<<1) to the polarization surface of the incident light sent from a light source 2 by means of a control signal given from a driver circuit 42. Thus the modulator 6 performes the modulation of light quantity of an angle frequency omega0. The light quantities of light spots 16 and 18 receive modulation of (1/2)XP0(1 - or + 2a0 sinomega0t), where Po is the total indident light quantity. Therefore the reflected light quantities sent from spots 16 and 18 receive modulations of 180 deg. phase difference to each other. In an unbalanced state, the amplitude of reflected luminous fluxes I 1 and I2 are different from each other. Therefore the component of the angle frequency omega0 is provided in the form of an unbalanced signal corresponding to a shift DELTAX34 between the spots 16 and 18 send from an information track 14 if the sum signal of said different amplitudes is detected.

Title: Anti-skid control unit
Inventor: MATSUDA TOSHIROU
IPC: B60T8/72
Filed: 1983-11-14
Abstract: PURPOSE:To reduce the control responsiveness by changing the threshold value used for the comparison calculation to determine a control mode to a larger value when the change of the wheel speed or wheel acceleration/deceleration is detected to be larger than a normal change. CONSTITUTION:A comparator 15 is provided with a threshold value change circuit 23 to change the preset deceleration, and a comparator 17 is provided with a threshold value change circuit 24 to change the preset acceleration. If the road surface condition is changed to a rugged road surface, irregular high-frequency oscillations are included in the wheel speed by being affected by the ruggedness of the road surface. The irregular high-speed oscillations of the wheel speed also affect the acceleration/deceleration. When changed frequencies are included in the acceleration/deceleration of the threshold value change circuits 23, 24, the values of the preset deceleration and preset acceleration are increased in response to these changed frequencies. Accordingly, the responsiveness of the comparison calculation to determine the control mode of the brake liquid pressure is made slow, thus the liquid pressure is controlled more correctly.
