摘要： The object of the invention is to provide an image carrier which is capable of securely preventing the leakage of charge in lateral direction so as to stably conduct the application or removal of charge and which can be easily manufactured. An image carrier comprises a dielectric layer, wherein charge is transferred between the dielectric layer and a charge-transfer controlling means so as to apply charge to or remove charge from the dielectric layer, wherein the dielectric layer is formed in such a structure that a large number of conductive portions are formed to be separately dispersed in its outer surface. Charge is transferred between the conductive portions and the charge-transfer controlling means so as to apply charge to or remove charge from the conductive portions.

摘要： An electrophoretic printing method comprises layering a back electrode and a dispersion system containing electrophoretic particles on a printing substrate to form a printing layer; and providing a printing head separately from the printing substrate. The printing head has a front electrode which is a counterpart of the back electrode and which has a predetermined printing pattern. The front electrode is brought into contact with the printing layer formed on the printing substrate to oppose the back electrode. Voltage is applied between the front electrode and the back electrode so as to change a distribution of the electrophoretic particles according to the polarity of the voltage and to form a desired image on the dispersion system.

摘要： A shaft encoder providing a pulsed output signal with rotation of a shaft, the number of pulses being dependent upon a shaft-mounted gear and its number of teeth. In a preferred embodiment, a piezo film element is mounted in intimate contact with a spring element, the latter being positioned to engage the teeth of the gear. When the shaft rotates, the gear rotates as well. The gear teeth cause the spring element to be displaced and then return to a nominal position for each tooth. Accordingly, given a sufficient number of regularly spaced teeth around the gear, a relatively high resolution pulsed signal is generated as the shaft rotates. The piezo film element generates electrical pulses due to the mechanical displacement of the spring element to which the film is in contact. Thus, no electrical power source is required to generate the pulses. Moreover, because of the simplicity of the invention, size scaling is readily available. Thus, the shaft encoder of the invention may be readily fabricated in extremely small configurations depending upon the desired application and the availability of machining or other techniques for producing small, accurately placed teeth. Furthermore, in an alternative embodiment, one tooth of the gear may be made slightly different from the others (i.e., higher) to provide a different pulse characteristic (i.e., greater amplitude) to indicate a reference position for the shaft. Moreover, the polarity of the generated pulse will indicate the direction of shaft rotation; i.e., positive for clockwise and negative for counterclockwise.
摘要翻译：轴编码器提供具有轴的旋转的脉冲输出信号，脉冲数取决于轴安装的齿轮及其齿数。在优选实施例中，压电膜元件安装成与弹簧元件紧密接触，弹簧元件定位成接合齿轮的齿。当轴旋转时，齿轮也旋转。齿轮齿使弹簧元件移动，然后返回到每个齿的标称位置。因此，给定足够数量的围绕齿轮的规则间隔的齿，当轴旋转时，产生相对高分辨率的脉冲信号。压电膜元件由于膜接触的弹簧元件的机械位移而产生电脉冲。因此，不需要电源来产生脉冲。而且，由于本发明的简单性，容易获得尺寸缩放。因此，本发明的轴编码器可以根据期望的应用和机加工的可用性或用于产生小的，准确放置的齿的其它技术的可能性而容易地制造成非常小的构造。此外，在替代实施例中，齿轮的一个齿可以被制成与其他齿稍微不同（即更高），以提供不同的脉冲特性（即，更大的振幅）以指示轴的基准位置。此外，产生的脉冲的极性将指示轴旋转的方向; 即逆时针方向为顺时针方向和负方向。

摘要： In an image forming apparatus, a resistant layer of each writing electrode is formed substantially in a semi-circular convex shape projecting upwardly. The top of the resistant layer is a spherical surface so that the resistant layer is in point contact with the charged layer of the latent image carrier. Because of point contacts, foreign matters adhering to the surface of the latent image carrier are easily allowed to pass, thereby preventing the occurrence of filming on the surface of the latent image carrier.
