Abstract: PURPOSE: To provide an antiskid hydraulic pressure controller for a multicircuit brake equipment which is improved in its safety by constituting same such that a magnet valve means of a specific construction is additionally provided to an antiskid hydraulic pressure controller for a single circuit brake equipment.  
     CONSTITUTION: A control valve 7 from which oil is not leaked out when a circuit is broken is disposed between a brake booster 2 as well as a right front wheel 8b and an antiskid actuator 4. The control valve 7 includes a hollow stepped piston 25, a plunger 28, a seat 32, balls 27, 29, a spring 33 and a magnet coil 34. Thus, during an ordinary braking operation with the antiskid operation being not effected, pressure oil from a master cylinder 2 is supplied directly to the left and right front wheels 8a and 8b, to the left rear wheel 9a through the control valve 7 and to the right rear wheel 9b through the actuator 4 to thereby effect braking operation. Meanwhile, with the antiskid operation being effective, a computer 6 responsive to a slipping phenomenon of the  car changes over a change-over valve 5 to abolish the communication between an intake manifold  3 and the actuator 4. As a result, the actuator 4 operates so that the pressure of oil to be supplied  to the right rear wheel 9b is decreased and the magnet coil 34 is energized to cause the control  valve 7 to operate so that oil under the decreased pressure is supplied from the actuator 4 to the  left rear wheel 9a.

Title: Magneto-optical head
Inventor: OKADA MITSUYA
IPC: G11B11/10
Filed: 1987-02-06
Abstract: PURPOSE:To eliminate an influence of birefringence in a substrate on a reproduced signal by providing a magneto-optical signal detecting part with a means which converts the change of the plane of polarization to that of light intensity, a laser condenser lens, a photodetector, and a shielding plate which is arranged between the laser condenser lens and the photodetector and has a circular aperture. CONSTITUTION:A magneto-optical signal detecting part 26 consists of an analyzer 28, a condenser lens 32, a shielding plate 40 having the circular aperture, and a photodetector 29. The shielding plate 40 arranged between the condenser lens 32 and the photodetector 29 functions to intercept the outside peripheral part of the laser light made incident on the photodetector 29. Since the obliquely incident light of the laser light made incident on the photodetector 29 corresponds to an obliquely incident component of the laser light incident on the substrate, this laser light is most affected by birefringence in the substrate. Therefore, the shielding plate 40 is used to eliminate the laser light incident on the photodetector 29. Thus, the deterioration in polarization state, namely, the deterioration of the regenerated signal accompanied with birefringence in the substrate is minimized.
