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： A reciprocatory dry shaver has a head from mounting three elongated cutter heads, one center cutter head and two outer cutter heads extending in parallel with each other. Each cutter head comprises a holder carrying a stationary cutter and a movable cutter driven to reciprocate in shearing engagement with the stationary cutter. The head frame is mounted on a shaver housing from which a reciprocating element projects to drive the movable cutter of each cutter head. The center and outer cutter heads are floatingly supported at individual longitudinal ends by associated center and outer spring members so that each cutter head is vertically movable relative to the head frame. The center spring members are formed in one of the head frame and the associated holder while the outer spring members are formed in the other of the head frame and the associated holders. Thus, the spring members for floatingly supporting the center and outer cutter heads can be effectively distributed to the head frame and the associated holders to enable compact arrangement for a system of floating supporting the three parallel cutter heads within a limited space.

摘要： An improved hand-held motor-driven oscillating razor for wet shaving provides a substantially vibration-free gripping during the shaving. The razor comprises a grip housing adapted to be gripped by the hand of a user and a shaver head movably supported on top of the grip housing. The shaver head carries a razor blade element and includes a weight which is driven by a motor to impart oscillatory movement to the shaver head. The motor is mounted within the shaver head together with the weight so as to confine an oscillatory system within the shaver head. A damper member is utilized to singly support the shaver head to the grip housing in order to made the shaver head movable with respect to the grip housing such that the grip housing can be isolated substantially from the oscillatory system in the shaver head, permitting the shaver head to oscillate substantially indpendently of the grip housing, thereby minimizing a counter-vibration transmitted back to the grip housing from the shaver head. The damper member is preferably configured to exhibit different elasticity in differing directions in order to minimize the counter vibration which the user feels during the shaving, while assuring effective shaving.

摘要： Reciprocal blade assembly of electric shaver having means for positively shaving specifically such long beard hair as ones extending along user's face skin or curling which are hard to shave, in addition to ordinary beard hair easy to shave. The means comprises an elongated bent part and slit-shaped hair inlet apertures made in an outer blade of a flexible steel foil fixed as bent semicylindrically to the shaver's head, the bent part being parallel to the longitudinal axis of the blade and the slit-shaped apertures substantially transversing the bent part, and an undulated part corresponding to the bent part and made in respective arcuate cutting blade edges of an inner cutter driven reciprocally to slide at the edges along the inner surface of the outer blade. Other hair inlet apertures made in the outer blade on both sides of the bent part for shaving mainly the ordinary hair are made, for example, to vary in diameter to gradually reduce rigidity against the bending of the outer blade as farther separated sideward from the bent part, whereby intimate contact between the semicylindrically bent outer blade and the inner cutter blade edges is maintained.

摘要： A hand-held depilating device capable of masking the pain of plucking the hairs through psychological effect. The depilating device comprises housing adapted to be grasped by the hand of the user and a plucking head mounted on top of the housing for plucking the hairs from the skin. Stimulator is mounted on top of the housing adjacent to the plucking head for providing mechanical stimuli to the skin while the plucking head operates to pluck the hairs. The stimulator comprises a vibrator which provides vibrations to the skin as the mechanical stimuli which act on sense receptors other than nociceptors that respond to pain, thereby masking the pain caused by plucking the hairs or received at the nociceptors. That is, the mechanical stimuli caused by the vibrations can activate Meissner's corpuscle or Pacinian corpuscle to make indistinct to the pain as demonstrated by a gate-control theory in psychology. Thus, the mechanical stimuli applied separately from the plucking operation can excite the tactile or pressure sense receptors so as to activate the gate control path at posterior horn of the spinal cord immediately before or simultaneously with the plucking the hair, thereby blurring the pain being transmitted through the nerve. Alternately, roller with stimulus projections may be utilized to apply the mechanical stimuli for alleviation of the pain.

摘要： A linear oscillating motor capable of assuring a consistent and effective feedback control of keeping a constant oscillation amplitude with varying load conditions. The linear oscillating motor comprises an oscillator carrying a permanent magnet, and a stator with an electromagnet. The electromagnet is supplied with an electric power to develop an electromagnetic drive force of moving the oscillator in a linear direction relative to the stator. A spring is provided to apply a restoring force to the oscillator for providing a linear oscillating motion to the oscillator. A photo-sensor monitors the linear motion of the oscillator and outputs a signal to a reverse-point detector which determines right and left reverse points of the oscillator. A controller applies the electric power to the electromagnet at the drive points respectively defined subsequent in time to the reverse points and in a varying amount for keeping a constant oscillation amplitude of the oscillator. The photo-sensor outputs a train of pulses appearing each time the oscillator passes its oscillation center. The reverse-point detector determines the reverse points based upon a time period between the two preceding pulses. Since the photo-sensor can monitor an oscillation cycle of the oscillator without being affected by the magnetic field developed by the electromagnet for driving the oscillator, it provides a reliable basis for accurately determining the reverse points and therefore the drive points. Accordingly, the driving force can be applied at an optimum timing to make the feedback control accurately and reliably.

摘要： A dry shaver with a skin stretcher comprises a shaver body and a shaving head mounted on top of the shaver body. The shaving head comprises at least one cutter unit with a perforated outer cutter. An inner cutter is driven to move in hair shearing engagement with the outer cutter. The skin stretcher comprises a skin contact elongated along the periphery of the outer cutter and a base through which the skin contact is held on the shaving head. A macro displacement structure is provided to allow the skin contact to be movable within a macro displacement range relative to the shaver body. The skin contact is made from an elastic material capable of being elastically deformed within a micro displacement range relative to the base. With the combination of the macro and micro displacements of the skin contact, the skin contact can be kept in contact with the skin of a user in conformity with various contours of the skin. Thus, the skin stretcher can stretch a large portion of the skin even with an uneven skin surface, i.e., around the chin or the like to raise the hairs over a wide area prior to the shaving by the cutter unit, thereby assuring smooth and effective hair shaving at the cutter unit.
