摘要： The present invention provides an apparatus for the handling of cleaned toner. The cleaning apparatus has a blade which removes residual toner from a photosensitive drum, a storage area partitioned into an upper and a lower section by a plate. In the preferred embodiment, a rotary device with paddles attached feeds toner to the rear of the lower section away from the cleaning blade and into the upper section. This insures the full use of the storage area. Plural rotary devices may be provided.

摘要： A process cartridge is detachably mountable to a main assembly of an electrophotographic image forming apparatus. The main assembly includes a motor, a gear receiving a driving force from the motor, a hole defined by twisted surfaces substantially coaxial with the gear and having a grounding contact. The cartridge includes an electrophotographic photosensitive drum, and a projection engageable with the twisted surfaces. The projection is provided at a longitudinal end of the drum. When the gear rotates with the hole and projection engaged with each other, a rotational driving force is transmitted from the gear to the drum through engagement between the hole and the projection. The cartridge also includes a grounding contact electrically connected with the drum, for electrically grounding the drum when the cartridge is mounted to the main assembly, and provided on the projection to be electrically connectable with the main assembly grounding contact.

摘要： There is provided a digital controller which can reduce a variation in output voltage as compared to the conventional digital controller at the time of abrupt changes in load and in input of a power amplifier. The digital controller is built in the power amplifier for supplying an output voltage vo to a load and is equipped with a manipulated variable calculating unit which detects the output voltage vo to calculate a manipulated variable ξ1 and a signal generating unit which converts the manipulated variable ξ1 into a signal for making the power amplifier operate. A feedforward function from an equivalent disturbance qy caused by the variation in the load is replaced by a feedback function from the output voltage vo and the manipulated variable ξ1, thereby allowing a transfer characteristic from the disturbance qy to the output voltage vo to result in a quadratic differential characteristic. Consequently, the variation in output voltage can be reduced as compared to the conventional controller at the time of the abrupt changes in the load and in the input of the power amplifier.

摘要： A robust digital controller is equipped with a high degree of approximation and is able to incorporate a novel two-degree-of-freedom robust digital control system without substantially considering the magnitude of the control inputs and there is provided its designing device. A control compensating means is configured as an integral type control system in which a discrete transfer function Wry(z) between a target value r and a controlled variable y is approximated to a higher-approximate quadratic approximate model transfer function Wm(z) and an arithmetic processing can be performed within the digital controller based on the model transfer function Wm(z). Further, the designing device automatically calculates parameters constituting the control system. Consequently, a robust digital controller can be easily realized that is equipped with a high degree of approximation as compared with a conventional approximate digital control system for realizing a first-order model and is robust against output noises.

摘要翻译： 强大的数字控制器具有高度的近似性，并且能够引入一种新颖的两度自由度鲁棒的数字控制系统，而基本上不考虑控制输入的大小，并提供其设计装置。 控制补偿装置被配置为整体式控制系统，其中目标值r和受控变量y之间的离散传递函数W（z）近似为较高近似二次近似模型 传递函数W m（z），并且可以在数字控制器内基于模型传递函数W（m）执行运算处理。 此外，设计装置自动计算构成控制系统的参数。 因此，与用于实现一阶模型的常规近似数字控制系统相比，可以容易地实现具有高度近似的鲁棒数字控制器，并且对输出噪声是鲁棒的。

摘要： A developer container with an increased capacity that does not enlarge a process cartridge or an apparatus main body used therewith includes flanges on an opposite surface of a developing frame respectively contacting flanges formed on the upper part and the lower part on a wall surface of a container frame, on which a developer feeding opening is formed. To form the developer, container the flanges are welded at their connection portions by ultrasonic welding. Then, a flange of a lid frame is connected to a flange of the container frame by ultrasonic waves, thereby forming a developer container, in which the container frame is connected with the developing frame with the developer feeding opening being put between the frames.
