    • A radioactive pellet injection apparatus includes a console (30) to be disposed beside a bed on which a patient is to be laid. The console (30) and the bed have brackets. An arm (39) is detachably coupled to the bracket of either one of the console (30) and the bed. The arm (39) is movable in either the horizontal or the vertical direction. A rotary driving unit (46) is mounted at a distal end of the arm (39) in such a manner that the tilt angle thereof can be adjusted about a horizontal axis (44) in response to a control signal. The rotary driving unit (46) carries a protective container (48) enclosing a capsule (60) with minute, spherical radioactive pellets enclosed therein, and a radiation detector (49) facing a catheter connecting section (50) extending from the capsule (60). A pump unit (32a) for supplying a carrier fluid for carrying radioactive pellets to the capsule (60) through a tube (51), a control circuit (32b) supplying a control signal to the rotary driving unit (46), and a detector circuit (32c) for processing a detection signal from the radiation detector (49) are disposed in the console (30).
    • 放射性丸粒注射装置包括一个待设置在病床上的床上的控制台(30)。 控制台(30)和床有括号。 臂(39)可拆卸地联接到控制台(30)和床中的任一个的支架。 臂(39)可在水平方向或垂直方向上移动。 旋转驱动单元(46)以这样的方式安装在臂(39)的远端处,使得其可以响应于控制信号围绕水平轴线(44)调整其倾斜角度。 旋转驱动单元(46)携带围绕胶囊(60)的保护容器(48),其中包围有微小的球形放射性粒子,以及面向从胶囊(60)延伸的导管连接部分(50)的辐射检测器(49) )。 一个泵单元(32a),用于通过管(51)将用于承载放射性颗粒的载体流体供给到胶囊(60);向旋转驱动单元(46)提供控制信号的控制电路(32b);以及 用于处理来自辐射检测器(49)的检测信号的检测器电路(32c)设置在控制台(30)中。

    • An amount-of-developer regulating apparatus configured to restrict the amount of developer carried on a developer bearing member. The amount-of-developer regulating apparatus includes a flexible developer amount regulation member having a contact portion configured to contact with a developer bearing member, and first and second holding portions configured to hold the developer amount regulation member and to contact with the developer amount regulation member at further upstream and further downstream in a direction where the developer bearing member is rotationally moved than the contact portion. With a pressure distribution of the contact portion as to the developer bearing member, there are a plurality of local maximum values in the direction where the developer bearing member is rotationally moved. Thus, the apparatus can be reduced in size, and also image concentration unevenness after long-term use can be prevented.
    • 一种显影剂调节装置,其被配置为限制承载在显影剂承载部件上的显影剂的量。 显影剂量调节装置包括柔性显影剂量调节构件,其具有构造成与显影剂承载构件接触的接触部分,以及构造成保持显影剂量调节构件并与显影剂量调节剂接触的第一和第二保持部分 构件在显影剂承载构件比接触部分旋转移动的方向的更上游和更下游。 通过接触部分对显影剂承载部件的压力分布,在显影剂承载部件被旋转移动的方向上存在多个局部最大值。 因此,可以减小装置的尺寸,并且可以防止长期使用后的图像浓度不均匀。
