Abstract: 本申请涉及机械传动技术领域,具体提出一种谐波减速器,包括有波发生器、柔轮、刚轮、输入转轴、后端盖、前端盖、前端盖轴承、后端盖轴承、后端盖油封和前端盖油封,还包括支承转轴和支承套,支承转轴与支承套之间设置为动配合连接,后端盖油封和前端盖油封安装设置在前端盖轴承和后端盖轴承之间。由于将后端盖油封和前端盖油封设置在腔体内,能够快速得到润滑油或脂对后端盖油封和前端盖油封的润滑,从而减少了后端盖油封和前端盖油封与输入转轴的摩擦力,延长了后端盖油封和前端盖油封的使用寿命;支承套与支承转轴替代了目前谐波减速器中常见的交叉滚珠轴承,提高了谐波减速器刚性及稳定性。

Abstract: 一种弯吸式内痔环扎器。它包括弧形吸头内管、释放硅胶环的弧形套管、筒式推动套管和负压针筒。弧形吸头可以很容易地在肛管齿线之上呈L型结构的直肠壁上吸取内痔组织以及供血管的直肠粘膜,然后进行环扎。使用时便于单手操作,减少了操作时间。负压针筒具有生成负压和作为环扎器手柄的双重功能,简化了环扎器的结构。推动套管轨道、轨道引导圆柱和楔子可确保释放硅胶环的弧形套管沿弧形吸头内管的平滑移动,且不易脱落。筒式推动套管与释放硅胶环的弧形套管之间通过半圆轮进行曲面转向,从而产生滚动接触,将动力直接传到硅胶环上,以达到轻便、平滑释放硅胶环从而进行环扎的效果。本发明设计合理,简单易用,且造价低,因而适合一次性使用。

The system comprises the identifier sequence generation portion and detection portion. The identifier sequence generation portion comprises: generating the frequency-domain random sequence; generating the frequency-domain orthogonal sequence; the frequency-domain truncating; frequency-time converting; the cycle extending. The identifier sequence receiving portion comprises: truncating the time-domain for the received signal; time-frequency converting; obtaining the frequency-domain signal; generating the frequency-domain random sequence; generating the frequency-domain orthogonal sequence; correlating the frequency-domain orthogonal sequence with the frequency-domain signal de-scrambled by the frequency-domain random sequence; detecting the result output from the frequency-domain correlator by the threshold-value detector and determining the transmitter identifier sequence. The generated random sequence of the present invention may be configured neatly according to the transmission bandwidth requirement, and the sequence may be arbitrarily allocated at the power of each frequency point inside bandwidth. The present invention may be widely applied to the multimedia broadcast, the terrestrial radio broadcast, the cable broadcast and the like.
