    • A standing-wave accelerating structure for accelerating charged particles wherein a converging force and a diverging force of an electric field to an electron beam are checked to improve the transmittivity of the electron beam through the accelerating structure and production of X-ray leakage is eliminated or minimized. The accelerating structure comprises a buncher section including at least one cavity for mainly bunching charged particles, and a regular section including at least one cavity. The diameter of a bore in the buncher section is smaller than the diameter of another bore in the regular section. A shorting bar for stopping propagation of microwaves is inserted in at least one of the cavities, and a means for accelerating the charged particles and for converging a beam is provided forwardly or rearwardly of the cavity in which the shorting bar is inserted.
    • 检查用于加速带电粒子的驻波加速结构,其中检查电场对电子束的会聚力和发散力,以提高通过加速结构的电子束的透射率,并且消除X射线泄漏的产生 最小化。 加速结构包括一个包括至少一个用于主要聚束带电粒子的空腔的整形器部分和包括至少一个空腔的规则部分。 聚束器部分中的孔的直径小于常规部分中另一个孔的直径。 用于停止微波传播的短路棒被插入到至少一个空腔中,并且用于加速带电粒子和用于会聚束的装置设置在插入有短路棒的空腔的前方或后方。

    • A development device having a development portion with a developer spout, to develop a latent image formed on an image carrier with developer including toner and carrier particles. The development unit also includes a circulation unit to convey developer collected from the development portion to the developer spout, a developer container, provided in the circulation unit, to contain the developer at a position upstream from the development portion in a developer circular direction, the developer container having a cylindrical upper portion and a funnel-shaped lower portion continuous with the cylindrical upper portion through a joint so that a level of the developer contained in the developer container at rest is positioned near the joint between the cylindrical upper portion and the funnel-shaped lower portion. An agitator is provided inside the developer container, to agitate and mix the collected developer and fresh toner supplied to the developer container.
    • 具有显影剂喷口的显影部分的显影装置,用于显影剂形成在图像载体上的潜像,显影剂包括调色剂和载体颗粒。 显影单元还包括循环单元,用于将从显影部分收集的显影剂输送到显影剂喷口,设置在循环单元中的显影剂容器,以在显影剂循环方向上的显影部分的上游位置容纳显影剂, 显影剂容器具有圆柱形上部和通过接头与圆柱形上部连续的漏斗形下部,使得容纳在显影剂容器中的显影剂的静止水平位于圆柱形上部和漏斗之间的接合处附近 形下部。 搅拌器设置在显影剂容器内部,以搅拌并混合收集的显影剂和提供给显影剂容器的新鲜调色剂。
