摘要： The automatic vehicle braking device is equipped with a braking force control processing portion which, based on the judgment result of a collision judgment processing portion and the judgment result of a steering avoidance judgment processing portion, imparts a turning property in a direction of head-on collision to the vehicle when the lateral position of the obstacle with respect to a travel route curve is large in a condition in which the driver is unconscious of a high possibility of collision between the vehicle and the obstacle and has taken no steering avoidance action yet. As a result, it is possible to reduce the speed of the vehicle and, at the same time, mitigate the damage suffered by the vehicle occupants at the time of collision.

摘要： An apparatus includes: an obstacle detecting unit for detecting a relative distance and a relative speed of an obstacle; a crash judgment unit for determining whether or not the driver's own vehicle will crash against the obstacle; and an obstacle handling device for reducing an impact caused at a time of a crash against the obstacle when the crash judgment unit has judged that the driver's own vehicle will crash against the obstacle. The crash judgment unit makes a crash judgment according to a limit distance enabling avoidance of the crash only through braking, when the obstacle detecting unit has detected a first obstacle in an area in front of the driver's own vehicle and a second obstacle in an area that is supposed to be entered by the driver's own vehicle afterward as a result of a steering operation for avoiding a crash against the first obstacle.

摘要： In a variable optical delay circuit to be used for compensation for polarization mode dispersion of an optical signal and for other purposes, there are provided a first birefringent member, a second birefringent member and a variable optical rotator interposed between the first birefringent member and the second birefringent member for varying a polarization state of light outputted from the first birefringent member. The birefringent members and the variable optical rotator are disposed on the same optical axis, and the optical axis of each of the birefringent members is set to perpendicularly intersect a traveling direction of inputted light. Therefore, by varying the optical rotation angle of the variable optical rotator, an arbitrary delay quantity corresponding thereto is obtainable in a continuous (analog-like) fashion without undergoing spatial separation between polarization components of the inputted light and varying the intensity (loss) of each of the polarization components.

摘要： A wavelength selector switch includes first and second refracting plates, an optical splitter, first and second optical systems, an optical coupler polarization controller, and second refracting plate. The first refracting plate refracts the second wavelength-multiplexed light beam. The optical splitter spatially splits into a plurality of wavelength components light beams. The first optical system changes the wavelength components into parallel light beams. The polarization controller selectively changes a polarization angle of each of the parallel light beams. The second optical system condenses the parallel light beams. The optical coupler multiplexes into a third wavelength-multiplexed light beam the parallel light beams condensed. The second refracting plate directs wavelength components of the third wavelength-multiplexed light beam to the first and second optical output ports depending on their polarization angles.

摘要： The invention comprises an isolation amplifier including an input circuit and an output circuit coupled through an isolation transformer. A switching type balanced modulator modulates a square wave carrier with an analog signal input and delivers the resulting signal to the input of the isolation transformer. A demodulator in the output circuit inverts alternate points of the modulated square wave carrier to essentially reproduce the analog input. A sample and hold capacitor circuit connected to the output of the demodulator fills the gap between the trailing and leading edges of successive pulses.
