20090037054 | VEHICLE STEERING CONTROL APPARATUS - A vehicle steering control apparatus includes an actuator to vary a steering gear ratio of a vehicle wheel steer angle of a steerable wheel to a steering wheel angle. A controller controls the actuator to produce an actuator torque in a steering direction at a start of a driver's steering operation. | 02-05-2009 |
20140303850 | STEERING CONTROL APPARATUS - A control computing unit allocates the current axial force and the transverse-G axial force at the predetermined allocation ratio to calculate a feedback axial force which is the steering-rack axial force. Then, the control computing unit drives the reaction force motor on the basis of the calculated feedback axial force. Additionally, the allocation ratio of the transverse-G axial force is set to be greater than the allocation ratio of the current axial force. | 10-09-2014 |
20140316658 | STEERING CONTROL APPARATUS - A control computing unit allocates a feedback axial force and a feedforward axial force at an allocation ratio based on an axial force difference which is a difference between the feedback axial force and the feedforward axial force to set a final axial force as a steering-rack axial force. The control computing unit drives a reaction force motor on the basis of the set final axial force. | 10-23-2014 |

20100310206 | OPTICAL MODULATOR - A technical problem related to a traveling wave electrode type of optical modulator comprising a substrate having the electro-optical effect, optical waveguides formed in the substrate, and a traveling wave electrode formed above the substrate includes improvement of the characteristics such as optical modulation bandwidth, driving voltage, and characteristic impedance of the traveling wave electrode type of optical modulator. To solve the problem, the structure of ridge portions is optimized which is formed in such a manner that a part of the substrate at regions where electric field generated by a high frequency electric signal traveling through the traveling wave electrode is strong is reduced in thickness by digging. Further, a buffer layer is formed over the substrate where the ridge portions are formed and a conducting layer is formed over the buffer layer. The thickness of at least one part of the buffer layer along the normal line of a side surface of the ridge portions is less than the thickness of the buffer layer on a bottom surface between the ridge portions formed by digging and/or the thickness of the buffer layer on a top part of the ridge portions. | 12-09-2010 |
