摘要： The shock absorber having a piston reciprocatingly disposed in a cylinder and sized small enough to permit a compact construction. The piston defines therein a vortex chamber with a maximum radius. The vortex chamber communicates with fluid chambers defined in the shock absorber via vortex passages formed in the piston. The vortex passage extends in the ceiling or bottom of the piston and tangentially opens at the upper and lower plane periphery of the vortex chamber. By providing the vortex passages in the above-mentioned manner, the radius of the vortex chamber can be maximized in relation to the radius of the piston thus reducing the size of the piston and, in turn the shock absorber.

摘要翻译： 该减震器具有往复地设置在气缸中的活塞，其尺寸足够小以允许紧凑的结构。 活塞在其中限定了具有最大半径的涡流室。 涡流室通过形成在活塞中的涡流通道与限定在减震器中的流体室连通。 涡流通道在天花板或活塞的底部延伸，并在涡流室的上下平面周向切向打开。 通过以上述方式提供涡流通道，涡流室的半径可以相对于活塞的半径最大化，从而减小了活塞的尺寸，从而减小了减震器的尺寸。

摘要： A hydraulic braking system of the split type including a fluid pressure control device which is adapted to reduce or stop the rate of increase of an output fluid pressure to wheel cylinders when a certain critical level is reached by an input fluid pressure delivered from a master cylinder, wherein the rates of increase of such critical level and the output fluid pressure if higher than the critical level are lowered when one of the split hydraulic circuits of the braking system fails or, if the rate of increase of the output fluid pressure higher than the critical level, only the critical level of the pressure is lowered.

摘要： A seat belt system includes a control arm with one end pivoted to an upper sash of a door and with the other end portion mounted to a roof side of a vehicle body for slidable movement. A seat belt extends from an anchor mounted to the roof side to a retractor mounted to the roof of the vehicle body adjacent the inboard side of a seat. A portion of the seat belt passes through the other end portion of the control arm. A spring is mounted so that when the door is closed, the other end portion of the control arm is urged to displace rearwardly till the control arm extends along the roof side to allow the seat belt to fasten around a passenger on the seat. As the door is opened, opening movement of the door will pull the one end of the control arm outwardly of the vehicle body, thus displacing the other end portion forwardly to extend the seat belt forwardly of the passenger for easy ingress or egress.

摘要翻译： 一种安全带系统，包括控制臂，其一端枢转到门的上窗扇，另一端部安装到车身的车顶侧，用于滑动。 座椅安全带从安装在屋顶侧的锚固件延伸到安装在车体顶部的与座椅内侧相邻的牵开器。 安全带的一部分穿过控制臂的另一端部。 安装弹簧使得当门关闭时，控制臂的另一端部被推动向后移位，直到控制臂沿屋顶侧延伸，以允许安全带固定在座椅上的乘客周围。 当门打开时，门的打开运动将拉动控制臂的一端到车体的外侧，从而使另一端部向前移动，以便将座椅安全带向乘客的前方延伸以便容易地进出。

摘要： Projections made of a different and less abrasion resistant kind of rubber to that constituting the exterior of the tire are arranged to contact the road during low pressure conditions, whereby the amount of rubber worn off indicates the amount of fatigue accumulated and degree of internal damage done by running the tire at that pressure.

摘要： A method of steering a wheeled vehicle having a first pair of steerable road wheels to be steered by human intervention and a second pair of steerable road wheels to be steered in response to a steering effort applied to the first pair of steerable road wheels, wherein the ratio between the angle through which the first pair of steerable road wheels is steered and the angle through which the second pair of steerable road wheels is to be steered is varied to establish a predetermined functional relationship between the ratio and a detected vehicle speed so as to eliminate the lateral slip of the vehicle when the vehicle is making a turn.
