Abstract: In a massage machine, a pair of rotatable shafts are mounted to extend through a top plate of a housing, and a pair of kneading balls are loosely fitted respectively to the top ends of the shafts. The shafts include oblique portions such that the kneading balls are rotated eccentrically to provide an oscillating motion. Cover pieces having spherical surfaces corresponding to the oscillating traces of the kneading balls are mounted about the rotatable shafts and interposed in a gap formed in the top plate of the housing. The kneading balls can be oscillated so that portions thereof circulate along the outer surfaces of the cover pieces. A vibration plate can be supported above the top plate by an elastic support leg, such that the massage machine can provide a kneading effect and a vibration effect simultaneously.

Abstract: In a hand type electric massage machine, a vibration head is connected through a coupling spring to a top end portion of a hand case, and an unbalance weight is rotatably mounted to a top end portion of a rotary shaft so that the center of gravity of a weight element is positioned on a line extending radially from a bearing of the rotary shaft. The weight element is fixed to a part of the periphery of a lower end portion of a cylinder base having nearly covered cylindrical form including a disc portion and a skirt portion extending downward from the periphery of the disc portion.

Abstract: A high potential generating toothbrush including an elongated, manually gripped block handle formed with a positive electrode; a block head formed with a negative electrode and having a brush implanted in one end thereof; and a high voltage generating circuit connected to those positive and negative electrodes for providing a high voltage to both those electrodes and incorporated in either the grip portion or the brush portion. With such construction, it is possible to treat diseases in the oral cavity, and the toothbrush becomes smaller in size and handy.

Abstract: A lathering device for providing shaving foam from liquid soap, wherein liquid is stored in a lower portion and forced upward by a vertical screw to an upper portion whereat the liquid is agitated into foam and ejected.

Abstract: A massaging vibrator where the motor is coupled directly to the vibrating pad and eccentric counter balance weights are disposed on both sides of the motor.
