摘要:
A diffraction element is disposed between a beam branching element (such as a beam splitter) and a photodetector. The diffraction element further segment an interference fringe introduced into stray light by a diffraction grating which divides a laser beam emitted from a laser beam source into a main beam and two sub-beams.

The container holder device includes a rotary body which is fixed to the lid body and held so as to slide up and down with respect to the holder body and so as to rotate, and a guide body which is formed on a side wall of the holder body. The rotary body is engageable with the guide body to rotate, along with the upward and downward sliding movements of the rotary body. Because the rotary body is engageable with the guide body to rotate, along with the upward and downward sliding movements of the rotary body, the rotary body can stably rotate while sliding. Because the lid body will rotate together with the rotary body while sliding, the lid body will move stably between the closed position and the open position. As the results, the moving orbit of the lid body can be made small, and the inner diameter of the storage space can be made small.

A steering control apparatus is provided for a vehicle having a steering wheel for steering steered wheels of the vehicle, a power source for generating power, and drive shafts for transferring the power to the steered wheels, to be served as driving wheels of the vehicle. The apparatus comprises an accelerating operation detection device for detecting accelerating operation amount by a vehicle driver, and a steering torque control device for controlling steering torque created by the steering wheel, and applying torque steer reducing torque to the steering wheel. The steering torque control device is adapted to reduce torque steer, which is transiently created on the steering wheel due to characteristics of the drive shafts, when the accelerating operation amount detected by the accelerating operation detection device becomes equal to or greater than a predetermined value.

In the control device for vehicles which executes a control of the vehicle by one calculation control device based upon a target control amount generated by another calculation control device connected to the one calculation control device by way of a communication means, the other calculation control device calculates an estimated target control amount by itself to compare it with the target control amount generated by the one calculation control device and input thereto by way of the communication means, or a third calculation control device compares the target control amounts generated by the one and the other calculation control devices and input thereto by way of the communication means, thereby to judge if an abnormality has occurred in the communication means, and to rapidly modify the control to make a counter-measure against the abnormality.

A steering device is provided for controlling steering torque applied to a steering wheel of a vehicle. A braking device is provided for controlling longitudinal force applied to each wheel, and a control device is provided for performing at least one of an anti-skid control and a traction control. It is observed whether the control device is performing the control on a split road surface. The steering torque is controlled on the basis of a difference of longitudinal force applied to the right and left wheels, and a turning state amount deviation between a turning state amount and a desired amount thereof. The desired amount of turning state is calculated, on the basis of the turning state of the vehicle obtained when one of the anti-skid control and the traction control is performed on the split road surface.

The present invention aims to receive a signal of tissue long in T2 at a relatively high level and suppress artifacts. When a magnetic resonance frequency of a component intended for measurement is assumed to be Ω and the frequency corresponding to a repetition time TR is assumed to be ωo, an RF pulse obtained by modulating a chemical shift SAT pulse for reducing a signal of a frequency Ω with cos (ωo·t) is applied as a leading pulse Po and thereafter a pulse sequence of Balanced SSFP is applied. Since a signal leading to the occurrence of artifacts is reduced owing to the effect of the leading pulse, the artifacts can be suppressed. Since a transient state is long in the same manner as conventional, such a signal of tissue long in T2 can be received at the relatively high level and contrast can be kept high by executing data acquisition in the transient state.

摘要:
In accordance with a vehicle motion control apparatus, a steering angle (θh) of a steering wheel is determined on the basis of a rotation angle (θpm) of an assist motor (24m) detected by a rotation angle sensor (24s) and a rotation angle (θvm) of a gear ratio variable motor (32m) detected by a rotation angle sensor (32s), and a VGRS control process (40a) of a gear ratio variable mechanism is executed on the basis of the determined steering angle (θh). Accordingly, since the steering angle (θh) of the steering wheel is determined on the basis of the rotation angle (θvm) used for the VGRS control process (40a) of the gear ratio variable mechanism and the rotation angle (θpm) used for an EPS control process (30a) of an EPS actuator, it is possible to obtain the steering angle (θh) of the steering wheel without a steering angle sensor. Therefore, it is possible to reduce the number of the parts of a vehicle motion control apparatus.
