IPC: A61L9/14
Filed: 1990-11-16
Abstract: PURPOSE:To liberate perfume as fine liquid droplets form by a prescribed quantity arbitrarily outside by connecting a fine stainless steel pipe as rigid body on the bottom part of a perfume tank filled with the perfume, installing a rotary body on the periphery of which a plurality of projection parts are arranged, and arranging the projection part so as to be in contact with a part of the lower part of the fine stainless steel pipe. CONSTITUTION:When a rotary body 7 revolves rightward, a projection part 8 shifts by revolution, and one of the projection part 8 comes in contact with the lower part of a fine stainless steel pipe 3. When the rotary body 7 revolves rightward, the lower part of the fine stainless steel pipe 3 is deformed through the shift of the projection part 8 in contact. Accordingly, the above-described lower part is pushed rearward and curved. Further, when the rotary body 7 revolves rightward, the contact of the projection part 8 with the stainless steel pipe 3 is released. Since the stainless steel pipe 3 possesses rigidity, deformation is generated by the repulsive force, and a perfume 2 which flows into a fine passage 4 is splashed outside as the fine liquid droplets 9 of the perfume from a fine opened port part 5.

Title: Voltage regulator apparatus with power boost system
Inventor: ARUFURETSUDO REONAADO SUTAATOU
IPC: G05F3/24
Filed: 1990-11-19
Abstract: PURPOSE: To improve the reliability of the regulator device by providing a means which selectively turns on a control transistor TR that has a control electrode, a 1st current-carrying electrode connected to the control electrode of an output TR and a 2nd current-carrying electrode connected to a fixed potential point. CONSTITUTION: When the voltage of an output terminal Vout drops, an N- channel TR T4 starts its turn-off operation and therefore the voltage rises at a node B. Thus an N-channel TR T6 is turned on more intensively. At the same time, the current flowing through a TR T3 increases because a TR T5 functions as a sink TR, i.e., a current source. Then the voltage drops at a node A and therefore a P-channel TR T2 is turned on more intensively. Furthermore, the TR T6 is turned on more intensively. As a result, the voltage of the terminal Vout is stabilized at the value equal to the reference voltage of a terminal Vref. Thus the reliability of a voltage regulator device is improved.
