  • Publication number: 20020177792
    Abstract: An ultrasonic wave cosmetic device for producing ultrasonic wave stimulation on the facial skin by a vibration unit having an ultrasonic wave vibration element. The ultrasonic wave cosmetic device includes a probe provided with a vibration unit where one surface of the vibration unit contacts the skin and another surface is structured by a horn connected to the ultrasonic wave vibration element, and a drive unit for driving the ultrasonic wave vibration element. The drive unit produces one of either a first fundamental frequency where a half-wave length thereof matches a thickness of the vibration unit when propagating therethrough, or a first harmonic frequency which is an integer multiple of the first fundamental frequency, as a drive frequency for driving the ultrasonic wave vibration element.

  • Publication number: 20020120218
    Abstract: An ultrasonic cosmetic treatment device that uses a simple electrical circuit structure to provide an effective method of controlling a thermal emission from a vibrating part when the vibrating part is not in contact with a predetermined surface, such as, for example, the skin of a person. The invention uses a probe comprised of a contact part on whose rear surface is attached an ultrasonic oscillator, and an oscillation circuit that drives the ultrasonic oscillator. An electrical load is applied to the vibrating part when the vibrating part is brought into contact with the skin, and released when the vibrating part is separated from the skin. The ultrasonic oscillator is controlled through a changeable oscillating frequency that is based on a larger impedance value for the vibrating part's non-load applied condition as compared to a smaller impedance value for a load applied condition.

  • Patent number: 6370676
    Abstract: A process sort test circuit and methodology for determining performance characteristic of an IC chip. The circuit is located on an IC chip itself and comprises an input for receiving an input signal; a first path from the input to a first output for transmitting the input signal to the first output, the first path sensitive to variations in a manufacturing process for the IC chip; a second path from the input to a second output for transmitting the input signal to the second output, the second path being substantially less sensitive to the variations in the manufacturing process for the IC chip; and, a pulse generator device coupled to the first and second outputs for detecting a difference in arrival times of the input signal at the first and second outputs and for outputting a sort signal if the difference is of a preselected magnitude. The sort signal enables output indication of a performance characteristic of the IC chip.

  • Patent number: 6212248
    Abstract: A shared path phase detector and phase indicator circuit provide a phase locked loop circuit for which loading and wiring dependencies are greatly reduced. The phase detector circuit is provided for receiving a reference clock and a second clock. The phase detector circuit provides a separate and unique signal for indicating the magnitude of the difference between the phase of the reference clock and the second clock, regardless of whether the second clock is leading or lagging the first clock. The phase indicator circuit detects whether the second clock is leading or lagging the first clock, and routes the pulses on a first internal signal path to generate either increment or decrement pulses depending on whether the second clock is lagging or leading, respectively.

  • Patent number: 6176840
    Abstract: Since the electrical impedance of an ultrasonic vibrator may vary according to the contact or non-contact of an application member with the skin, a detection circuit detects the contact or non-contact of the application member with the skin by converting the current the ultrasonic vibrator current into a voltage, and a comparator compares this voltage with a reference voltage. When contact is detected by the detection circuit, a constant-voltage circuit sets the level of the constant voltage output to the ultrasonic oscillation circuit at a standard voltage, but when non-contact is detected, the constant voltage is switched to a lower-level constant voltage. Thus, when non-contact is detected, the level of the ultrasound emitted from the ultrasonic vibrator via the application member is lowered, so that an unnecessary rise in the temperature of the application member is be prevented.

  • Patent number: 6064235
    Abstract: A shared path phase detector circuit for receiving a reference clock and an oscillator clock, the phase detector circuit providing an output signal for indicating a magnitude difference between a phase of the reference and oscillator clocks. The output signal is independently derived from the leading or lagging edge relationship of the reference and oscillator clocks. The output signal does not describe which signal leads, but only the width magnitude difference. The design provides a single path over which the output signal travels, without feedback, such that the circuit dependencies are greatly reduced.

  • Patent number: 5944664
    Abstract: A method of measuring the amount of dislocation of the cervical vertebrae of the patient includes a step of defining, on the base posterior view, an end point on a line connecting a point representing the front end of the nasal septum and a point being equidistant from a pair of ocular orbits; a step of determining, on each side of the base posterior view, a point of intersection (or contact) of the "profile of a foramen magnum of a skull" and the region where a condyle of the skull is joined to, or in close proximity to, a superior articular pit of atlas; and a step of defining, on the base posterior view, a bisector of the angle which a line connecting the front end point to one of the points of origin forms with respect to another line connecting the front end point to the other of the points of origin. The amount of dislocation of the cervical vertebrae is determined by means of the bisector.
