摘要： A dry shaver has a cradle head carrying shaving units as well as a motor for driving the shaving units. The cradle head is supported to a hand grip such that it is allowed to tilt about at least one tilt axis parallel to a thickness direction of the hand grip. At least one portion of the motor projects upwardly of the tilt axis, whereby the cradle head is given overall mass center which is located upwardly of the tilt axis with respect to the height axis of the hand grip. Accordingly, the motor of heavy nature can be best utilized to locate the overall mass center of the cradle head above the tilt axis for generating a torque acting to tilt the cradle head from a neutral position about the tilt axis when the hand grip is held upright.
摘要翻译： 干燥剃须刀具有摇动头部，带有剃须单元以及用于驱动剃须单元的电机。 支架头被支撑在手柄上，使得允许其围绕平行于手柄的厚度方向的至少一个倾斜轴线倾斜。 马达的至少一部分向倾斜轴线向上突出，由此托架头部被赋予相对于手柄的高度轴线的倾斜轴线上方的整体质量中心。 因此，可以最好地利用重的自动电动机来将托架头的整体质量中心定位在倾斜轴线上方，以产生用于当手柄被保持直立时用于使托架头从靠近倾斜轴线的中立位置倾斜的扭矩 。

摘要： A linear oscillating actuator system which is capable of canceling out the stator vibrations for driving a load with a minimum of vibrations. The system includes an oscillator carrying a permanent magnet as well as an output shaft for connection to the load. A stator assembly is incorporated within a housing and is configured to movably support the oscillator and to carry an electromagnet. The electromagnet generates a magnetic field which interacts with the permanent magnet to reciprocate the oscillator relative to the stator assembly in a linear path. A balancer is added to the system for canceling out undesired stator vibrations. The balancer are commonly supported to the stator assembly to be driven thereby in parallel with the oscillator. The balancer is configured to have a mass generally equal to that of the oscillator and to be devoid of any output member. Thus, the oscillator and the balancer are driven in a counter reciprocating manner, thereby keeping the stator assembly free from counter-vibrations and therefore driving the output shaft with a maximum output power.

摘要： A reciprocatory dry shaver comprises a stationary cutter, a movable cutter, and a permanent-magnet linear motor having a stator and a reciprocator which is driven by an electric current to reciprocate relative to the stator. The reciprocator carries the movable cutter to reciprocate it in shearing engagement with the stationary cutter. A power circuit is included to provided an electric power to the motor. The shaver includes a detector which detects a displacement of the movable cutter and give an output indicative of the detected displacement of the movable cutter. Also included in the shaver is a controller which varies the electric power being fed to the motor in a feedback manner based upon the output from the speed detector in order to keep an oscillation amplitude of the movable cutter at constant. In this manner, the movable cutter can reciprocate without being jammed even when experiencing a heavy lead during the shaving, thereby avoiding undesired speed reduction of the movable cutter which would result in the lowering of the cutting efficiency. Thus, the reciprocatory dry shaver is capable of keeping a constant oscillation amplitude irrespective of a lead acting on a movable cutter to thereby assure a sharp cut even when the movable cutter experiences a heavy lead during the shaving.

摘要： In an oscillation type linear actuator for reciprocally moving a plurality of moving members held in parallel with each other in a predetermined direction owing to electromagnetic action between a stator and them, two moving members reciprocally moving in opposite phases with each other are coupled by a coupling member having spring function, and a non-displacing portion of a plate spring portion of the coupling member which is not displaced substantially is restricted by a stopper. Even when an external force is applied to one of two moving members reciprocally moving in the opposite phases each other, motion of the other moving member is transmitted to the moving member via the coupling member, so that reduction of amplitude of the moving member to which the external force is applied can be restricted, and a balance of amplitudes of two moving members is maintained.
