Title: Pen point or nozzle used for pressurized viscous fluid
Inventor: OTSUKA KATSUMI
IPC: B05C17/00
Filed: 1998-05-18
Abstract: PROBLEM TO BE SOLVED: To make rotation light and to uniformly apply a high-viscosity liquid by forming a ball or roller in such a manner that this ball or roller is not received by a mechanical bearing. SOLUTION: When a pen point 3 progresses in an arrow direction, the ball 1 is pulled to an adhesion layer 9 and tends to remain on a left side, making a rear spacing 8 smaller and a front spacing 7 larger. The ball 1 is eliminated of mechanical contacts exclusive of a contact 11 with a body 10 to be worked to provide a perfect fluid bearing. As a result, the rolling resistance at the contact 11 is lessened and the ball 1 immediately begins to rotate clockwise. The velocity of the viscous fluid in the front spacing 7 is made larger than the velocity in the rear spacing 8 and the ball 1 is pushed back rightward by a Maguns effect without coming into contact with an inside surface 6. When the pen point 3 is pulled up after the end of writing, the ball 1 is pushed down and is tightly fitted to a bubble sheet 5 by the pressurized viscous fluid 2 in the inner deep part. At this time, a thin layer of the viscous fluid is left in the portion exposed from the aperture 4 of the ball 1 so as to be ready for next use.

Patent JP-S5874081-A (JP)
Title: Semiconductor device
Inventor: HARA TOMONORI
IPC: H03F1/42
Filed: 1981-10-29
Abstract: PURPOSE:To allow the sufficient protection of an element even when the gate breakdown voltage decreases, by forming a protection element serving both as an emitter.base short-circuitting diode of a lateral P-N-P transistor and as a  vertical transistor. CONSTITUTION:The emitter.base of a laterlal P-N-P transistor Tr 400 are short- circuitted resulting in the formation of a protection diode. When a surge is impressed on an input terminal I, a depletion layer extended from the collector  side of the Tr 400 reaches the emitter, and then a current instantaneously flows  from the emitter into the collector by punch-through. Since this current serves  as the base current for the vertical N-P-N Tr 500, the Tr 500 turns conductive  and discharges the charge of the surge impressed on the terminal I into the terminal E. Thereafter, since the voltage of the terminal I is immediately attenuated when the surge voltage disappears, the base current for the Tr 500 is not  supplied resulting in no conduction of the Tr 500. Since the collector current for  the Tr 400 generates at the point when of the base current of the Tr 500 is low, the corresponding punch-through voltage generates also at the point of low  voltage. Thereby, even when the gate breakdown voltage of a MOSFET 300 decreases, the protection is performed.
