摘要： Automatic self-aligning ball metals rotatably mounted at both end parts of a rotor shaft in an electric motor are supported by holding devices. The holding device is designed in the form of a disc having a flange portion around the outer periphery thereof. It is formed with a plurality of pawls having different intensities of resilient force which extend in the radial direction from an area located in the proximity of the flange portion. The pawls having a higher intensity of resilient force and the pawls having a lower intensity of resilient force are alternately arranged in the peripheral direction of the holding device and the inner part of each of the pawls is bent at a certain inclination angle. The pawls having a lower intensity of resilient force are adapted to come in contact with the metal ball earlier than the pawls having a higher intensity of resilient force. Each of the pawls having a higher intensity of resilient force has a width wider than the pawls having a lower intensity of resilient force. The pawls having a higher intensity of resilient force may have a thickness more than the pawls having a lower intensity of resilient force on the assumption that they have the same width. Usually, two kinds of pawls which are alternately arranged are used. Three kinds of pawls may be employed.
摘要翻译：可旋转地安装在电动机中的转子轴的两个端部的自动调心球金属由保持装置支撑。保持装置被设计成具有围绕其外周的凸缘部分的盘的形式。它形成有多个棘爪，其具有不同强度的弹性力，其从位于凸缘部分附近的区域沿径向方向延伸。具有较高强度的弹性力的棘爪和具有较低强度的弹力的棘爪在保持装置的周向方向上交替布置，并且每个爪的内部以一定的倾斜角弯曲。具有较低强度弹性力的棘爪适于比具有较高强度弹性力的棘爪更早地与金属球接触。具有较高强度的弹力的每个棘爪具有比具有较低的弹力强度的爪宽的宽度。具有较高强度的弹性力的棘爪的厚度可以具有比具有较低的弹性力强度的棘爪的厚度，假设它们具有相同的宽度。通常，使用交替排列的两种棘爪。可以采用三种爪。

摘要： One of several corona dischargers used in an electrophotographic apparatus is connected to a power source transformer so as to selectively operate these corona dischargers. The power source transformer is provided with a tertiary winding, to which a switching device is connected. When the switching device is turned on, a secondary output from the transformer becomes lower than a corona discharging limit voltage, whereby the corona discharging stops.
