PURPOSE: An ultrasonic vibration induced dental floss, an ultrasonic vibration induced dental brush, and a sound wave induced dental brush are provided, which can keep hygiene of the mouth by using an ultrasonic wave generator. CONSTITUTION: An ultrasonic vibration induced dental floss comprises a handle part(140), a depositary(120), and head unit(110). In the handle part, an ultrasonic wave generator is installed at the inside thereof and an on/off switch(150) of the ultrasonic wave generator is installed in the outer circumference. The depositary is installed to the upper end of the handle part. A dental floss reel is installed inside the depositary. The head unit is installed to the upper end of the depositary. The dental floss extracted from the depositary can be hung. If the on/off switch is turned on, the ultrasonic wave generator vibrates, the vibration is delivered to the head unit, and the dental floss is vibrated.
Abstract:
PURPOSE: An optical I/O(Input/Output) bus system which uses an optical interconnect with an optical PCB is provided to transmit a signal without bottleneck and signal distortion by implementing an I/O bus system based on an optical PCB(Printed Circuit Board). CONSTITUTION: An SerDes(Serializer and Deserializer)(100) is connected to a CPU or a memory, divides a serial signal to a parallel signal, and collects the parallel signal to the serial signal. A photoelectric converter(110) converts a serial/parallel signal to an optical signal. An optical transferring unit is parallely arranged in order to transfer the optical signal. An optical switch(120) switches an optical signal into an optical transferring unit according to the address of the converted optical signal.
