    摘要： An ultrasonic wave applying apparatus which is safe and convenient for use. The apparatus includes an hand-held applicator having a vibration element which is, in use, contact with a skin of a user to apply ultrasonic waves to the skin, a power source providing a DC voltage, an oscillator circuit which is energized by the DC voltage from the power source to generate an oscillating output for driving the vibration element, and a load detecting circuit which monitors whether the vibration element is loaded such as by contact with the skin and provides a load detection signal when the vibration element is so loaded. In addition, a motion detecting circuit is provided to monitor whether the vibration element is moving and give a motion detection signal when the vibration element is so moving. A control circuit is connected to the load detecting circuit and the motion detecting circuit for controlling the driving circuit to reduce the oscillating output being fed to the ultrasonic vibration element when the load detection signal is not received within a predetermined first time period or when the motion detection signal is not continuous over a critical time duration within a predetermined second time period even in the presence of the load detection signal being detected within the first time period.

    摘要： An improved self-oscillation system for a linear oscillatory actuator composed of a stator and a reciprocator. The stator carries a winding to which an electric current is periodically supplied for making a resonant oscillation of the reciprocator. The system includes a self-oscillation circuit for continuing the resonant oscillation of the actuator by a positive feedback manner based upon a back electromotive force (Vbemf) appearing across the winding. The system further includes a PWM control for increasing the electric current in response to a decreasing oscillation amplitude due to an increasing load applied to the reciprocator. A detector circuit is included to monitor the oscillation amplitude of the reciprocator and provides a corresponding detector output in response to which the self-oscillation circuit provides a drive pulse of varying pulse width for making the PWM control. The detector circuit is connected to monitor Vbemf of the winding in the absence of the electric current and to judge the instant oscillation amplitude of the reciprocator based upon the monitored Vbemf. Thus, the system can eliminate an external sensor, yet assuring the PMW control reliably based upon Vbemf correctly reflecting the actual oscillation of the reciprocator.

    摘要： In a hair dryer with a brush emitting minus ion to a hair in brushing, effect of the minus ion for hair treatment is increased. The hair dryer is comprised of a main body and a brush unit detachably engaged with an air outlet of the main body. A plurality of ion outlets is provided on a housing of the main body and disposed outside of the air outlet so that minus ion is emitted toward the brush unit. Since the minus ion emitted from the ion outlet is not shielded by the hair in brushing, the minus ion can be sprayed widely to the hair, and not directly heated by hot air flow blowing from the brush unit.

    摘要： In a power impact tool for fastening a screw or a bolt, malfunction that driving of a motor is stopped before the screw or the bolt is fastened completely can be prevented. A fastening judger judged that the fastening operation is completed at least when a torque variation ratio becomes substantially zero and a reference index becomes equal to or larger than a threshold value of trouble judgment. The reference index is a number of impact of a hammer in a term in which the torque variation ratios take positive values, and the threshold value of trouble judgment is calculated with using a maximum value of the torque variation ratio in the term. Since the number of the impact of the hammer due to trouble in fastening operation is smaller than that due to the screw or the bolt is fastened completely, it is possible to distinguish the increase of the torque in the former case from the increase of the torque in the latter case.
