摘要： An oil seal assembly includes an oil seal having a lip contacting the outer peripheral surface of a reciprocating shaft, a holder for holding the oil seal about the shaft, and an annular spring for urging the lip against the outer peripheral surface of the shaft. The lip has a flat surface which is inclined with respect to the outer peripheral surface of the shaft. When the oil seal is mounted on the shaft, the flat surface is brought into surface contact with the outer peripheral surface of the shaft by an urging force applied by the spring.

摘要： A Stirling engine seal assembly includes a seal ring body and an expander. The seal ring body consists of a matrix made of polytetrafluoroethylene compounded and filled with carbon fibers and at least one powder selected from the group consisting of carbon powder, boron nitride powder and molybdenum disulfide powder. The plate expander is in abutting contact with the inner peripheral surface of the seal ring body for urging the seal ring body in the direction of its outer circumference.

摘要： An oil-ring comprising a pair of side rails and an expander disposed between the side rails. The expander extends in a circumferential direction and has waves in a radial direction. At both sides of radially inner portions of the expander, side rail engaging portions protrude in an axial direction. The side rail engaging portions are formed as paired side rail engaging sections within one pitch of the waves, by defining a slit extending in the axial direction at a central portion of one side rail engaging portion. Due to the division from one side rail engaging portion to paired side rail engaging sections, the rigidity of each side rail engaging portion can be weakened appropriately, and each side rail can follow against the cylinder bore surface satisfactorily, thereby decreasing oil consumption.
摘要翻译：一种油环，包括一对侧轨和设置在侧轨之间的膨胀器。膨胀机在圆周方向上延伸并具有沿径向的波浪。在膨胀机的径向内侧的两侧，侧轨接合部沿轴向突出。侧轨接合部分通过限定在一个侧轨接合部分的中心部分处沿轴向延伸的狭缝形成为波浪的一个节距内的成对的侧轨接合部分。由于从一个侧轨接合部分到一对侧轨接合部分的分离，每个侧轨接合部分的刚性可以被适当地削弱，并且每个侧轨可以令人满意地跟随缸膛表面，从而减少了油耗。

摘要： The annular expander of a piston ring assembly with vertically extending notches each of which is formed on either side of a plurality of circumferentially spaced upstanding tabs projecting from the top and bottom edges of the expander. The tabs, which form the abutments for the inner peripheral edges of upper and lower annular side rails, the outer peripheral edges of which are in sliding contact with a cylinder wall, undergo elastic deformation made possible by the notches when the corresponding side rails are subjected to a strong force received from the cylinder wall owing to piston wobble during reciprocation. The elastic deformation of the tabs assures that the side rails will remain in contact with the cylinder wall at all times during the reciprocation of the piston.
摘要翻译：活塞环组件的环形膨胀器具有垂直延伸的凹口，每个凹槽形成在从膨胀机的顶部和底部边缘突出的多个周向间隔开的多个突出的突出部的任一侧上。形成用于其外周边缘与气缸壁滑动接触的上下环形侧轨的内周边缘的突出部，当相应的侧轨受到影响时，会产生由凹口产生的弹性变形在往复运动期间由于活塞摆动而从缸壁接收的强力。突片的弹性变形确保了在活塞往复运动的过程中，侧轨将始终与气缸壁保持接触。

摘要： An automatic disc selection type reproducing apparatus comprises a disc accommodating mechanism having disc accommodating portions for accommodating discs, and a reproducer part provided below and movable along the disc accommodating mechanism. The disc accommodating mechanism is substantially arranged horizontally, and the discs are accommodated within the disc accommodating portions in a vertical state where a disc surface of one disc opposes a disc surface of an adjacent disc. The reproducer part moves and stops at a position opposing a disc which is designated by designating an address of the disc accommodating portion which accommodates this disc. The reproducer part has a disc carrying mechanism for carrying the disc which assumes the vertical state, upwardly and downwardly between the disc accommodating mechanism and the reproducer part, while supporting a lower portion of an outer peripheral edge of the disc. The disc carrying mechanism supplies the disc from the disc accommodating portion to the reproducer part by use of the weight of the disc when playing the disc, and returns the disc into the disc accommodating portion by separating the disc from the reproducer part when the playing of the disc is completed.
摘要翻译：一种自动盘片选择型重放装置，包括一盘片容纳机构，其具有用于容纳光盘的光盘容纳部分，以及设置在光盘容纳机构下方并可移动的再生器部分。光盘容纳机构基本上水平布置，并且在一个盘的盘表面相对于相邻光盘的盘表面的垂直状态下，光盘容纳在光盘容纳部分内。再现器部分在与通过指定容纳该盘的盘容纳部分的地址指定的盘相对的位置移动并停止。再现器部分具有用于承载盘的盘片传送机构，该盘片在盘容纳机构和再现器部分之间向上和向下呈现垂直状态，同时支撑盘的外周边缘的下部。盘片运送机构在播放盘片时通过使用碟片的重量将光盘从光盘容纳部分提供给再生器部分，并且当播放光盘时将光盘与再现部分分离，将盘片返回到光盘容纳部分光盘完成。
