    摘要： A nozzle wiping apparatus comprises an ink-absorbent sheet placed below the ink discard hole to collect the sucked ink discarded through the ink discard hole and an ink absorbent sheet winding mechanism to wind up the ink-absorbent sheet. The ink-absorbent sheet is kept in contact with a part of the nozzles after completion of the purging operation so the nozzles may be moved relative to the ink-absorbent sheet to thereby wipe ink deposited on the nozzles.

    摘要： A washing machine includes a washing shaft for rotating agitating blades disposed in a dewatering tank, and the washing shaft is disposed coaxially on a hollow dewatering shaft for rotating the dewatering tank. The washing shaft is connected to the output side of a reduction mechanism, and a washing side input shaft is connected to the input side of the reduction mechanism to rotate the washing shaft by decelerating the rotation of a drive motor. A rotor of the drive motor is coupled to the lower part of the washing side input shaft. Therefore, the rotating torque of the agitating blades can be increased without increasing the torque of the drive motor. In addition, if the laundry collides against the agitating blades, the eccentricity to the washing side input shaft is suppressed, thereby the increase of the washing capacity can be handled without increasing the size of the drive motor.

    摘要翻译： 洗衣机包括用于旋转设置在脱水罐中的搅拌叶片的洗涤轴，洗涤轴同轴地设置在中空脱水轴上，用于旋转脱水罐。 洗涤轴连接到减速机构的输出侧，洗涤侧输入轴连接到减速机构的输入侧，通过减速驱动电动机的旋转来使洗涤轴旋转。 驱动马达的转子联接到洗涤侧输入轴的下部。 因此，可以在不增加驱动电动机的转矩的情况下增加搅拌叶片的旋转扭矩。 此外，如果衣物与搅拌叶片碰撞，则抑制了对洗涤侧输入轴的偏心，从而可以在不增加驱动马达的尺寸的情况下处理洗涤能力的提高。

    摘要： A washing machine motor drive device drives a motor using an inverter circuit, which implements a constant torque control through a change in the torque-revolution speed characteristic of the motor. This facilitates an easy control of braking torque (negative torque), thereby providing a maximized braking torque. An easy control of regenerative energy is also provided, and back electromotive force is consumed by the internal resistance of the motor. Practically described, DC power of a rectifier circuit connected to an alternating current source is converted by an inverter circuit into AC power for driving the motor for operating an agitator or a washing/spinning tub. Motor rotor position is detected by rotor position detector, motor current is detected by current detector, and a control device controls the inverter circuit for resolving the motor current into a current component corresponding to magnetic flux and a current component corresponding to torque. At a motor braking operation, the current component corresponding to magnetic flux and the current component corresponding to torque are controlled independently. As a result, the torque at high speed revolution can be increased, or the efficiency at low speed revolution can be improved. This leads to the use a downsized and energy-conscious motor, and contributes to the prevention of an abnormal rise of DC voltage in the inverter circuit.

    摘要翻译： 洗衣机电机驱动装置使用逆变器电路驱动电动机，其通过电动机的转矩转速特性的变化实现恒定的转矩控制。 这容易控制制动转矩（负转矩），从而提供最大的制动转矩。 还提供了对再生能量的容易控制，并且反电动势被电动机的内部电阻消耗。 实际上，连接到交流电源的整流电路的直流电力由逆变器电路转换成用于驱动用于操作搅拌器或洗涤/旋转槽的电动机的交流电力。 电机转子位置由转子位置检测器检测，电机电流由电流检测器检测，控制装置控制变频器电路，将电机电流分解成与磁通相对应的电流分量和与转矩对应的电流分量。 在电动机制动操作中，独立地控制对应于磁通量的电流分量和对应于转矩的电流分量。 结果，可以提高高速旋转时的转矩，或者可以提高低速旋转的效率。 这导致使用小型化和节能型电动机，并且有助于防止逆变器电路中的直流电压的异常升高。

    摘要： A motor drives, via a hollow dryer shaft, a basket doubling as a washing basket and a spin-dryer basket. The motor rotating speed is reduced by a speed reduction mechanism, thereby driving an agitator disposed in the basket via a washing shaft that is axially aligned with the dryer shaft. A clutch switches transmission of the motor driving force either to the dryer shaft or to the washing shaft. The speed reduction mechanism and the motor are axially aligned with one another. The clutch is placed within a motor bracket, and is controlled by a clutch driver that is inserted into the bracket through a hole provided on the motor bracket. These arrangements restrain unbalance of a water tub during a dehydrating step, as well as prevent water or fingers of users from entering the motor.

    摘要： An ink jet printer having bubble purging arrangement for discharging bubbles mixed in the ink out of a print head. The print head has a main tank for storing ink, a sub tank for collecting and storing ink, and a manifold fluidly connecting the main tank and the sub tank. The manifold is in fluid communication with the nozzles for supplying ink from the main tank to the nozzles. Three kind of purging modes are provided in accordance with purging position of the print head. Pressurizing pump is selectively connected to the main tank or sub tank or both main tank and the sub tank through a valve arrangement. If the pump is fluidly connected to the main tank only, the ink in the main flows into the sub tank. If the pump is fluidly connected to the sub tank only, the ink in the sub tank flows back into the main tank. By alternating the fluid connection, bubbles mixed in the ink is gradually concentrated at an upper portion of the manifold. If the pump is fluidly connected to both the main tank and the sub tank, the concentrated bubbles is positively discharged outside through the nozzles.
