Abstract: Disclosed is a discharge device (20) which comprises a power supply unit (22) that supplies a first voltage, a piezoelectric transducer (24) that increases the first voltage to a second voltage by means of vibrations, and a first electrode (26) for producing a discharge product (P) by performing a discharge upon application of the second voltage. The first electrode (26) and the piezoelectric transducer (24) are electrically connected with each other via a vibration damping unit (30). In other words, the first electrode (26) and the piezoelectric transducer (24) are arranged to be out of contact with each other.

Abstract: An ultrasonic skin care device has an applicator head for applying the ultrasound vibrations to a user's skin. The applicator head has a vibrator element and a horn which are integrated into a combined vibration mass that resonates with an electric pulse to produce the ultrasound vibrations. The device is configured to limit the ultrasound upon detection that the applicator head is out of a normal contact with the skin. A load detecting circuit detects whether the applicator head is in a normally loaded condition or in an unloaded condition with reference to electrically equivalent impedance of the combined vibration mass. The combined vibration mass has a structure that restrains vibrations at a center portion of the vibration mass in order to reduce an undesired parasitic resonance, thereby enabling to discriminate the impedance given under the normally loaded condition from that given under the unloaded condition.

Abstract: In an ultrasonic vibration device (1) for hairstyling, which has a vibration element (10) for generating ultrasonic vibrations, and a horn (2) for amplifying vibrations generated by and transmitted from the vibration element. The horn (2) has a vibration entrance surface (21) of an oblong rectangular shape to which the vibration element (10) is connected and through which the vibrations generated by the vibration element enters into the horn, and a vibration exit surface (22) through which the vibrations propagated in the horn exits. The horn (2) has a cross sectional shape in a lateral direction of the oblong rectangular shape so that a width in the lateral direction becomes gradually narrower from the vibration entrance surface (21) to the vibration exit surface (22), and the vibration exit surface (22) has at least a convex portion, such as a hemi-cylindrical shape.

Abstract: An ultrasonic wave hair set apparatus is configured by a main frame, an ultrasonic vibration block provided on the main frame, a pinching lever rotatably provided on the main frame, a presser plate provided on the pinching lever and having a pressing face. The ultrasonic vibration block is further comprised of an ultrasonic oscillator and an ultrasonic horn having a vibration face, and a comb shaped protection member is provided to enclose the vibration face. Even if a user penetrates a finger between the pinching lever and the main frame, the finger touches the protection member, so that it rarely touches the vibration face directly. Consequently, the ultrasonic vibrations are not transmitted to the finger, and burn injury can be prevented.

Abstract: In an ultrasonic washer for washing by splaying washing toward an object to be washed or a portion to be washed from a front end of a nozzle, a part of an ultrasonic wave propagation member connected to an ultrasonic transducer is protruded into a cavity of the nozzle into which the washing is filled in order to propagate ultrasonic vibration generated by the ultrasonic transducer to the washing efficiently. Furthermore, the ultrasonic wave propagation member is formed so that a cross-sectional area becomes gradually smaller as approaching to the front end thereof, so that the ultrasonic vibration is converged to the end face of the ultrasonic wave propagation member.
