Abstract: The apparatus is formed of a centrifugal force and Coriolis force generating device and a gas and liquid separation device. The centrifugal force and Coriolis force generating device gives high energy to supplied liquid by generating a spirally flowing air stream therein, to thereby ion-dissciate the liquid. Also, it provides energy necessary to micronize and activates the liquid drops with the centrifugal force and Coriolis force acted in the spirally flowing air stream. The activated liquid drops ionize oxygen particles at the gaseous side when electric doublets is oriented on the surface of the liquid drops, thereby causing groups of negative ions to be generated. The gas and liquid separation device separates the gas and liquid sent out from the centrifugal force and Coriolis force generating device and discharges air including negative ions into the atmosphere.

Abstract: The present invention relates to an integrated circuit for driving a d.c. motor with radio control comprising a receiving circuit for receiving and detecting certain signals transmitted from a transmitter, an amplifier for amplifying an output signal of said receiving circuit, a peak detector for converting the said amplified audio signal into a d.c. voltage, a comparator which have a hysteresis character dependent on the output level of the peak detector, a voltage regulating circuit supplying a stabilized voltage into all other components, and a direction control circuit to generate logic control signals deciding actual operation mode of the d.c. motor and motor driving circuits to produce motor driving signals by the output signal of the direction control circuit.

Abstract: This invention relates to a roller bicycle having rollers rotably mounted on the front wheel shaft and a single rear wheel for a common use as a sporting and playing apparatus on which one can ride forward and backward by keeping his balance, thereby improving his agility and developing his physical strength.
