摘要： A reciprocatory dry shaver has a shaving head carrying an outer cutter, and an inner cutter. An actuator is mounted in the shaving head for driving the inner cutter. The actuator includes an oscillator which carries a joint for driving connection to the inner cutter. Resilient coupling links are provided to support the oscillator to the shaving head in order to allow the oscillator to reciprocate relative to the shaving head. The resilient coupling link has its upper end coupled to the oscillator and has its lower end which is farther away from the inner cutter than the oscillator and is anchored to the shaving head. Thus, the oscillator is supported as being floated or lifted with respect to the shaving head, thereby being allowed to travel along a path which is somewhat arcuate in coincidence with the arc of the outer cutter.

摘要： A reciprocatory dry shaver capable of driving an inner cutter smoothly along an arcuately curved outer cutter for efficient shaving. The dry shaver includes a shaving head carrying an outer cutter which is arcuately curved along its length, and an inner cutter driven to reciprocate along the length of the outer cutter. An actuator is mounted in the shaving head for driving the inner cutter. The actuator includes an oscillator which reciprocates in the lengthwise direction of the outer cutter and carries a joint for driving connection to the inner cutter. Also included in the actuator is a resilient coupling link which supports the oscillator to the shaving head in order to allow the oscillator to reciprocate relative to the shaving head. The resilient coupling link has its one end coupled to the oscillator and the other end anchored to the shaving head at a portion away from the inner cutter than the oscillator. Thus, the oscillator is supported as being floated or lifted with respect to the shaving head, thereby being allowed to travel along a path which is somewhat arcuate in coincidence with the arc of the outer cutter. Accordingly, the oscillator, i.e., the inner cutter carried thereon can be guided smoothly along the arc of the outer cutter, assuring smooth and efficient shaving.

摘要： In a rolling driving actuator used as a drive source of a power toothbrush, permanent magnets are formed flat plate shape, and constituting a moving object by being attached to grooves formed on an outer peripheral face of a yoke which is press-fitted to and fixed on a shaft. On the other hand, a tubular shaped stator, which is constituted by a coil wound around a bobbin and stationary yokes provided on both side of the bobbin in axial direction of the shaft, is provided to face an outer face of the permanent magnet or an outer face of the yoke of the moving object with a predetermined clearance so that a center axis thereof becomes coaxial with the center axis of the shaft. By supplying an alternating current to the coil, the moving object is driven in rolling driving around the axis of the shaft.

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. Furthermore, since a component having the plate spring portion is used as the coupling member, it is possible to downsize the oscillation type linear actuator.
