摘要： A suspension control system for an automotive vehicle is provided. This suspension control system comprises variable damping force shock absorbers and a control unit which controls the shock absorbers to assume damping force characteristics in a range between preselected higher and lower damping coefficients. The control unit is operable to provide a control parameter indicative of bouncing motion of a vehicle body based on sprung vertical speed to determine a damping coefficient against the bouncing motion. When the control parameter is greater than a threshold value, the damping coefficient is modified to a lower value, while when the control parameter is less than the threshold value, the damping coefficient is modified to a higher value. With this damping coefficient modification, the bouncing motion is suppressed effectively while assuring passenger comfort.

摘要： An anti-rolling motion control system for an automotive vehicle is provided. This control system comprises shock absorbers each being variable of a damping coefficient within a range from softer to harder damping characteristics, a steering sensor for monitoring a steered angle of a steering wheel, and a rolling motion control unit. The rolling motion control unit is operable to derive steered angular velocity based on the steered angle of the steering wheel. The rolling motion control unit controls the shock absorbers so that the damping coefficients are modified to exhibit the harder damping characteristics when the steered angular velocity and the steered angle are greater than preselected first and second threshold values respectively for suppressing rolling motion of a vehicle body effectively while securing traveling stability.

摘要： Observation samples in a sample solution are held due to absorption or the like on a rear face of a first X-ray transmission film. In a mirror body, while an X-ray emission film and X-ray transmission films are bent to be convex outward due to a pressure difference, an X-ray transmission film is bent to be convex toward the X-ray transmission film side due to gas expansion in a second cavity part. This bending results in widening of a gap between the first and second X-ray transmission films in their center part more compared with a gap between their end parts. However, there is almost no change between the X-ray transmission films.
