Abstract: ABSTRACT        There is provided an optical external modulator that can modu-late the polarization of incident light without regulating the state of polarization of the light entering the modulator.  Such a modulator can be suitably incorporated into an optical telecommunications system.  An optical external modulator according to the invention comprises a sub-strate 1, an optical transmission line 7, a polarization modulating section 11 and a phase changing section 8 for changing the state of polarization of the light passing through the optical transmission line by applying stress to the optical transmission line 7 as a function of a modulation signal given to the modulator such that the phase difference between the X-component and the Y-component of the light being propagated through the optical transmission line 7 is shifted by (2m-1)*.pi./2 (m is a positive integer).

Abstract: Device for controlling an actuator of construction equipment prevents voiding of a target actuator, by controlling inertia load and power load and reducing heat generated in its return oil channel by means of controlling the aperture of the return oil channel. The device includes directional control valve 14a for controlling a target cylinder 15a of construction equipment.  The directional control valve is switched and controlled by a pilot valve 19a which is provided with an operating lever. A meter-out circuit is provided between target actuator 15a and a tank line 16, the meter-out circuit being separated from a meter-in circuit which is connected to control valve 14a.   A meter-out valve 32 provided in the meter-out has a throttle position and a large aperture position, the throttle position being adjusted by external signals Pi, corresponding to strokes of the respective operating levers. External signals Pi, for controlling the aperture of meter-out valve 32, are restricted so as not to exceed limiter pressure which is determined by function between the rotation speed of engine 11 which drives the source of hydraulic pressure and degree of operation of operating levers of other actuators.
