    • A fluid pressure control apparatus for controlling a solenoid valve to increase and decrease a fluid pressure by varying a valve opening degree includes a controller to control the fluid pressure by varying a command current for driving the solenoid valve. The controller calculates a hysteresis correction quantity to reduce a hysteresis effect of a hysteresis characteristic of the fluid pressure outputted from the solenoid valve with respect to the command current varied in an increasing direction and a decreasing direction, and varies the command current to control the fluid pressure to a target pressure in accordance with the hysteresis correction quantity. The controller calculates the hysteresis correction quantity in accordance with a turn-to-turn variation quantity determined from a current difference between a first command current value at a first changeover of a varying direction of the command current from one of the increasing and decreasing directions to the other and a second command current value at a second changeover of the varying direction of the command current before the first changeover.

    • A supporting and driving mechanism including a rotatable body and a supporting unit for assuring stable support and rotation of the rotatable body for a long time. The mechanism includes an axis member at either end of the rotatable body, a driven gear at one end of the rotatable body, two rollers and a driving gear of the supporting unit. The two rollers are placed parallel to each other and the distance between the closed surfaces of the rollers is smaller than the diameter of the axis member of the rotatable body. The driving gear engages the driven gear and transmits a driving force to the driven gear of the rotatable body. The driving force applied from the driving gear to the driven gear directs between the centers of the two rollers when the driving force is translated so that the origin of the force is brought to the center of the axis member of the rotatable body. Thus the axis member is pressed toward the two rollers while the rotatable body is driven by the supporting unit, whereby the position of the axis member is fixed and the stable rotation of the rotatable body is assured for a long time.
    • 一种支撑和驱动机构,包括可旋转体和支撑单元,用于长时间确保可旋转体的稳定支撑和旋转。 该机构包括在可旋转体的任一端的轴构件,可旋转体的一端的从动齿轮,支撑单元的两个辊和驱动齿轮。 两个辊彼此平行放置,并且辊的封闭表面之间的距离小于可旋转体的轴构件的直径。 驱动齿轮接合从动齿轮并将驱动力传递到可旋转体的从动齿轮。 当驱动力平移时,从驱动齿轮施加到从动齿轮的驱动力在两个辊的中心之间引导,使得力的原点被带到可旋转体的轴构件的中心。 因此,轴构件被压向两个辊,而可旋转体由支撑单元驱动,由此轴构件的位置是固定的,并且可旋转体的稳定旋转被长时间保证。
