  • Patent number: 6572637
    Abstract: A handbreadth-sized laser beam projecting probe for beauty treatment, comprising: a semiconductor laser device for producing a laser beam; a drive circuit for driving the semiconductor laser device; a heat sink for removing the generated heat from the semiconductor laser device; a CPU for controlling the radiation of the laser beam from the semiconductor laser device; a condenser lens for condensing the laser beam from the semiconductor laser device; an adjuster for adjusting the distance between the skin and the condenser lens; and an on-and-off switch associated with an electric power supply. The handbreadth-sized probe can be carried everywhere, permitting the practice of beauty treatment when desired.

  • Patent number: 6496735
    Abstract: A portable pulse beauty treatment apparatus according to the present invention permits one to move freely while taking a desired pulse beauty treatment, thus making it unnecessary to allot a relatively long time of period exclusively to the pulse beauty treatment. A belt bag contains a control box having a pulse generator installed therein for effecting a pulse beauty treatment, and one wears the belt bag round one's waist. An electroded union suit has bundles of wires connecting its flat electrodes to the pulse generator in the control box, thus permitting the pulse generator to supply the flat electrodes with a train of pulses via the bundles of electric wires. The control box has two pairs of electrodes provided on its opposite sides for measurement of body impedance.

  • Patent number: 6453203
    Abstract: A pair of electrode tights which does not require that one be naked when lying down to take a beauty treatment. Six pairs of flat electrodes EL1 to EL6, ER1 to ER6 are attached to selected places symmetrical relative to the center fine inside of the garment, with the flat electrodes facing the underbelly, the inguinal region, the hip, the femoral region, the rear side of the knee and the calf of the body. These flat electrodes are connected to a pulse beauty treatment apparatus via electrically conductive press studs and a bundle of electric wires. The pair of electrode tights may have an elongated tubular bag for containing the bundle of electric wires. The elongated tubular bag has a fastener running along its full length for holding together two parts of the bag, and a plurality of relay terminals fixed inside for connecting the electric wires to the flat electrodes.

  • Patent number: 5820625
    Abstract: A light depilating apparatus comprising a light depilating probe, an electric controller, and a connection cable for connecting the light depilating probe to the electric controller whereby the light depilating probe is brought into contact with a portion of skin to be depilated; wherein the light depilating probe includes: a hollow body; a head cap having opened and closed ends and being attached at its opened end to one end portion of the body so as to form an inner space in the head cap; a transparent contacting cylinder provided on a head of the head cap at its closed end so that the cylinder is brought into contact with skin; a holding block provided in the inner space of the head cap; a connection cap provided at the other end portion of the body to hold a terminal of the cable connected to the electric controller; a plurality of light-emitting sources constituted by semiconductor laser elements mounted in holes formed in the holding bock so as to be excited by the electric controller through electric c
