    • An intake system for an internal combustion engine is disclosed. The intake system comprises a cylindrical member, a first intake passage portion which extends axially within the cylindrical member, two side walls which extend circumferentially on the outer side of the cylindrical wall of the cylindrical member and which are spaced apart from each other in the axial direction of the cylindrical member, a second intake passage portion downstream of the first intake passage portion which is formed between two side surfaces, facing each other, of the two side wall, and an opening formed on the cylindrical wall of the cylindrical member to communicate the first intake passage with the second intake passage. The cylindrical member with the opening is turned to vary the effective length of the second intake passage portion. A distance between the two side surfaces of the two side walls varies such that the longer the effective length of the second intake passage portion becomes by the turning motion of the cylindrical member, the shorter the distance becomes.
    • 公开了一种用于内燃机的进气系统。 进气系统包括圆柱形构件,在圆柱形构件内轴向延伸的第一进气通道部分,在圆柱形构件的圆柱形壁的外侧周向延伸并且在轴向上彼此间隔开的两个侧壁 所述第一进气通道部分的下游侧的第二进气通道部分,所述第二进气通道部分形成在所述两个侧壁的彼此面对的两个侧表面之间;以及开口,形成在所述圆筒形构件的圆筒壁上以连通 具有第二进气通道的第一进气通道。 旋转具有开口的圆柱形构件以改变第二进气通道部分的有效长度。 两个侧壁的两个侧表面之间的距离变化,使得第二进气通道部分的有效长度由于圆柱形构件的转动而变长,距离变得越短。

    • A variable speed tape transport apparatus for a tape cassette wherein the tape is driven at a selected one of plural predetermined speeds. The cassette includes speed indications thereon, each indication representing a respective normal tape speed. These indications are sensed by a sensor which, in turn, controls a control circuit for the tape drive motor such that the tape is selectively driven at a normal relatively lower speed or at a normal relatively higher speed. In addition, a selector mechanism, such as a fast-forward or rewind mechanism, is provided to enable the tape to be driven at a fast speed, this fast speed being at least equal to the relatively higher normal speed.In one embodiment, a tape cassette to be driven at the relatively lower normal speed can be selectively driven at a first higher speed, equal to the relatively higher normal speed, and at a second even higher speed. In this embodiment, a cassette to be driven at the relatively higher normal speed can be selectively driven at the second higher speed.
    • 一种用于磁带盒的变速磁带传送装置,其中磁带以选定的多个预定速度驱动。 盒式磁带包括速度指示,每个指示表示相应的正常磁带速度。 这些指示由传感器感测,传感器又控制用于磁带驱动电动机的控制电路,使得磁带以正常的相对较低的速度或正常的相对较高的速度选择性地驱动。 此外,提供了诸如快进或倒退机构的选择机构,以使得能够以快速的速度驱动带,该快速速度至少等于相对较高的正常速度。
