  • Patent number: 7329252
    Abstract: An apparatus for laser depilation according to the present invention uses a semiconductor laser diode, which is controlled in respect of its energy level, thereby permitting an economical, effective and safe cosmetic treatment. The power output of light of the semiconductor laser diode ranges from 5 to 1500 mW, and the peak wavelength ranges from 600 to 1600 nm. The controller of the semiconductor laser diode comprises pulsating power output control means and radiation period control means for setting a desired length of time for radiation. With these control means the energy level of the beam of light from the laser may be so controlled that a strong beam of light may be thrown for a relatively short time, or that a weak beam of light may be thrown for a relatively long time. Thus, hairs of different thickness and colors can be removed.

  • Patent number: 7214222
    Abstract: A laser depilating method for depilating treatment by irradiating a skin surface with a laser beam emitted from a semiconductor laser. A treatment region of the skin surface is treated with a semiconductor laser beam for an irradiation time of 100 msec or more per irradiation while controlling the laser beam so that the energy density when irradiating the skin surface may be in a range of 0.01–1 J/mm2. Irradiation of the skin surface with a semiconductor laser beam under such a condition provides a more secure and efficient treatment effect of laser depilation. A plurality of semiconductor laser beams are used as necessary to irradiate a wider area of skin surface at a time.

  • Patent number: 6860835
    Abstract: Disclosed is an exercise amount measuring device using as an exercise signal generator an inclination detector commercially available, which can detect two-dimensional movements. Use of such inclination detectors facilitates the assembly of exercise amount measuring devices. The inclination detector 1 is connected to a counter circuit via an input circuit, and the input circuit and the counter circuit are connected to an MPU via an input-and-output port. The input circuit comprises a CR circuit or a flip-flop circuit. The counter circuit counts input pulses post-chattering exclusion, which input pulses are caused by the on-and-off switching actions, which are brought every time the contact ball touches selected contact electrodes in the inclination detector.

    Abstract: A laser beam projector equipped with a CCD camera for taking a picture of a spot for treatment, thus permitting observation of the spot by sight. The laser beam projector has an annular projection formed around a circular hole made on the front of its casing, and a trapezoid heat sink is fitted in the circular hole with its base caught by the circumference of the annular projection. The annular projection has threads formed on its outer circumference. A tapered cap has a laser beam throwing aperture made on its top end. The tapered cap is screwed and fixed to the annular projection, and the tapered head is applied to the spot with the laser beam aperture closed with the skin. The heat sink has a through hole made at its center, and a magnifying lens is placed deep in the through hole, and is directed to the laser beam throwing aperture. The CCD camera is placed behind the magnifying lens with its focal plan aligned with the lens.

  • Patent number: 6736807
    Abstract: The instrument of the present invention irradiates a relatively large skin area evenly with laser beams. A plurality of semiconductor laser diodes are arranged to form two lines with the semiconductor laser diodes of one line staggered with those of the other line, and the semiconductor laser diodes of each line are so inclined that their laser beams may focus on a single line. With this arrangement the plurality of laser beams provide a linear distribution of narrow beam, and the scanning area on the skin can be expanded accordingly. The beauty treatment on the skin or the depilation treatment can be expedited significantly. Advantageously the focusing points of the laser beams are distributed at an increased density, and the irradiation strength averages everywhere to attain the even beauty treatment.
