    摘要： A centrifugal compressor has diffusers which convert a high velocity, low pressure stream of fluid which flows out of an impeller to a high-velocity high-pressure flow due to the action of a purality of stator blades disposed near the outer periphery of the impeller. In this compressor, the portion of the stator blade or of an auxiliary blade which is provided in the diffuser located on the side of a front shroud is disposed closer to the impeller than the portion thereof located on the side of a main shroud, and the leading edge of the stator blade is thus inclined from the portion thereof located on the side of the main shroud to the portion thereof located on the side of the front shroud. The configuration of the front edge of a stator blade or of an auxiliary blade which is provided in the diffuser is so improved as to restrict back flow which occurs on the side of the front shroud when the flow rate is small and to lower the minimum flow rate. Furthermore, an auxiliary blade and an intermediate blade are disposed between the adjacent stator blades, and the leading edge of the auxiliary blade is so improved as to enlarge the operation range of the diffuser and to improve volume control greatly.

    摘要翻译： 离心压缩机具有扩散器，其将来自叶轮的高速，低压流体流转换成高速高压流，这是由于设置在叶轮外周附近的多个定子叶片的作用。 在该压缩机中，设置在位于前罩侧的扩散器中的定子叶片或辅助叶片的部分比位于主护罩一侧的部分更靠近叶轮设置， 因此，定子叶片的前缘从其位于主护罩一侧的部分倾斜到位于前护罩一侧的部分。 设置在扩散器中的定子叶片或辅助叶片的前缘的构造被改进，以限制当流量小时在前护罩侧发生的回流，并且降低最小流量 率。 此外，辅助叶片和中间叶片设置在相邻的定子叶片之间，并且辅助叶片的前缘被改善以扩大扩散器的操作范围并且极大地提高体积控制。

    摘要： A pickup cable for a stringed instrument can switch between the output of the direct vibrational sound of strings and the output of the sound from the stringed instrument body generated by the vibrations of the strings and can also simultaneously output both the sound components. The pickup cable for a stringed instrument includes an input terminal to be inserted in a jack of the stringed instrument; a microphone to collect and convert sound of an internal space of the stringed instrument into collected-sound electrical signals; and an output terminal to output the collected-sound electrical signals. The microphone is incorporated in the input terminal.

    摘要： The invention relates to a capacity control method for controlling the capacity of a multistage compressor in response to a flow rate signal by varying the openings of vanes at individual stages. The relationships of the openings of the vanes of the individual stages are made to vary in response to the flow rate signal from the multistage compressor. Thus, when the flow rate of the multistage compressor is far from the anti-surge capacity within the operable range thereof, it is possible to select vane opening relationships which provide the highest efficiency for the multistage compressor. When the flow rate of the multistage compressor drops to either a value near the anti-surge capacity or the inoperable range, on the other hand, it is possible to select vane opening relationships which provide an enlargement of the operating range of the multistage compressor, before the flow rate enters that inoperable range.

    摘要翻译： 本发明涉及一种容量控制方法，用于通过改变各级叶片的开口来响应流量信号来控制多级压缩机的容量。 各级的叶片的开口的关系响应于来自多级压缩机的流量信号而变化。 因此，当多级压缩机的流量远远超过其在可操作范围内的防喘振能力时，可以选择为多级压缩机提供最高效率的叶片开度关系。 另一方面，当多级压缩机的流量下降到接近防喘振能力或不可操作范围的值时，可以选择提供多级压缩机的工作范围的叶片开度关系， 在流量进入不可操作的范围之前。
