摘要： A steering gear apparatus of the rack-and-pinion type including a pinion formed with helical teeth and a rack member formed with helical teeth which are brought into meshing engagement with the helical teeth of the pinion in such a manner that a steering effort is applied to the meshed portion of the helical teeth of the pinion and rack member at a predetermined angle relative to an axis line of the rack member, the rack member being resiliently biased toward the pinion, wherein the helical teeth of the pinion or the rack member each are formed with a tip portion to be brought into engagement with each root of the helical teeth of the rack member or the pinion.

摘要： A holder for use in cutting the outside surface of a cylindrical blank, the inner bottom of which has a concave spherical seat, to make said outside surface concentric with said concave spherical seat, characterized in that a rotatable shaft of a smaller outside diameter than the inner diameter of said blank and having a tip bearing against said concave spherical seat is provided longitudinally with three equi-distant grooves. A concave spherical surface is formed at the bottom of each of said grooves and this surface has a concave spherical surface of radius R with its axis running at right angles to the longitudinal direction of said rotatable shaft. In each groove of said shaft is slidably inserted an expansion pawl having at its top a projection bearing against the inside surface of said blank and having at its bottom a convex spherical surface of radius r (R > r). The invention includes a method of correcting concentricity by using said holder.
摘要翻译：一种用于切割圆柱形坯料的外表面的保持器，其内底具有凹形球形座，以使所述外表面与所述凹形球形座具同心，其特征在于，具有比所述凹形球座小的外径的可旋转轴，所述坯件的内径和具有抵靠所述凹形球形座的尖端轴承纵向设置有三个等距离的凹槽。在每个所述凹槽的底部形成有凹形的球形表面，并且该表面具有半径为R的凹形球形表面，其轴线与所述可旋转轴的纵向方向成直角。在所述轴的每个凹槽中可滑动地插入一个膨胀爪，其膨胀爪在其顶部具有抵靠所述坯料内表面的突出轴承，并且在其底部具有半径r（R> r）的凸形球形表面。本发明包括通过使用所述保持器来校正同心度的方法。

摘要： A cylinder-head cover for use in an internal combustion engine, which effectively separates oil and contaminants from blowby gas-oil mixture prior to the time when the blowby gas-oil mixture is suctioned into an intake passage. The cylinder-head cover has extension portions which extend in its lateral direction, and is attached by a curved plate onto its back side, thereby forming a space between the cylinder-head cover and the curved plate. The curved plate has grooves which extends in zigzags relative to its longitudinal direction. The blowby gas-oil mixture passes through the space defined between the cylinder-head cover and the curved plate. As the volume of the space is repeatedly large and small, the flow speed of the blowby gas-oil mixture reduces at the place where the space is large. Hence, the oil or contaminants drop by its weight. Thus, the oil and contaminants, which are contained in the blowby gas, are separated.
摘要翻译：一种用于内燃机的气缸盖罩，其在窜气瓦斯油混合物被吸入入口通道之前有效地将油和污染物与窜气瓦斯油混合物分离。气缸盖罩具有沿其横向方向延伸的延伸部分，并且通过弯曲板附接到其后侧，从而在气缸盖罩盖和弯曲板之间形成空间。弯曲板具有相对于其纵向方向以锯齿形延伸的凹槽。闷气瓦斯油混合物通过气缸盖和弯曲板之间限定的空间。当空间的体积重复大小时，在空间较大的地方，闷气瓦斯油混合物的流动速度降低。因此，油或污染物的重量会下降。因此，包含在窜气中的油和污染物被分离。
