摘要： A damper obtaining damping force by the frictional resistance imparted by the viscosity of the magnetic viscous fluid is disclosed. The damper is provided with a seal not only on one (lower side) of the axial outer sides of the yoke but also on the other (upper side) of the axial outer sides of the yoke to trap the magnetic viscous fluid within the magnetic viscous fluid filling portion at both axial outer sides of magnetic viscous fluid filling portion. Because the leakage of the magnetic viscous fluid can be prevented, no air is introduced into the magnetic viscous fluid filling portion, to allow the density of the magnetic viscous fluid within magnetic viscous fluid filling portion to be maintained at a favorable level and prevent degradation of damping force.

摘要： A washing machine includes a rotatable tub in which an agitator is disposed. A tub shaft connected to the rotatable tub is mounted on a base for rotation. A clutch is mounted on the tub shaft to be reciprocally moved so that the clutch engages a clutch engagement hole of the base and an engagement protrusion of a motor rotor alternately. An operation lever mounted on the base is operated so that the clutch is reciprocally moved. The bottom of the base includes a region of rotational locus of the clutch. The region is flat except for the clutch engagement hole so that the clutch is prevented from engaging a portion other than the clutch engagement hole. A reed switch is mounted on the base to be turned on when detecting engagement of the clutch with the clutch engagement hole. A control device proceeds from a dehydration stage to a next stage only when the reed switch is turned on. When the reed switch is not turned on, the rotatable tub is rotated at a low speed with the operation lever being maintained in the operable state, so that an operation for engaging the clutch with the clutch engagement hole is re-executed.
摘要翻译： 洗衣机包括旋转桶，搅拌器设置在该旋转桶中。 连接到旋转桶的桶轴安装在基座上用于旋转。 离合器安装在梭筒轴上以往复移动，使得离合器交替地与基座的离合器接合孔和马达转子的接合突起接合。 安装在基座上的操作杆被操作，使得离合器往复移动。 底座的底部包括离合器的旋转轨迹区域。 除了离合器接合孔之外，该区域是平坦的，从而防止离合器与离合器接合孔以外的部分接合。 当检测离合器与离合器接合孔的接合时，簧片开关安装在基座上以被接通。 只有当簧片开关打开时，控制装置才从脱水阶段进行到下一阶段。 当簧片开关未被接通时，旋转桶在操作杆保持在可操作状态下以低速旋转，从而重新执行用于使离合器与离合器接合孔接合的操作。

摘要： Printheads and methods of operation. In one embodiment, a printhead includes a plurality of jetting channels comprising first jetting channels configured to jet a first print fluid and second jetting channels configured to jet a second print fluid, and a driver circuit communicatively coupled to actuators of the jetting channels. The driver circuit receives a drive waveform comprising non-jetting pulses and jetting pulses, and gating signals comprising a first active gating signal designated for jetting the first print fluid, and a second active gating signal designated for jetting the second print fluid. The driver circuit selectively applies the non-jetting pulses and the jetting pulses to actuators of the first jetting channels based on the first active gating signal to jet the first print fluid, and selectively applies the jetting pulses to actuators of the second jetting channels based on the second active gating signal to jet the second print fluid.

摘要： Printheads and manifolds within printheads. In one embodiment, a method comprises determining a resonant frequency of jetting channels for a printhead, and selecting a target length for a manifold fluidly coupled to the jetting channels such that resonant frequencies of the manifold differ from the resonant frequency of the jetting channels by a threshold amount.

摘要： A carriage assembly for a printer that reciprocates along scan directions. The carriage assembly includes at least one printhead having a row of jetting channels for ejecting a print fluid, and reservoirs mounted on the carriage assembly that each supply the print fluid to the printhead. At least one of reservoirs is mounted on the carriage assembly to be offset from the row of jetting channels.
