IPC: H02P3/18
Filed: 1985-04-02
Abstract: PURPOSE:To prevent a thyrsitor converter from causing the commutation failure on momentary service interruption, by breaking regenerative power with a self-arc-suppressing switching circuit provided between the thyristor converter and a smoothing condenser, when the momentary power interruption occurrs during regenerative operation. CONSTITUTION:Between a thyristor converter 3 and a smoothing condenser 7, a diode 9 and a self-arc-suppressing switching element 8 are connected in series to be inserted. An AC power source 1 is provided with a voltage detector 11, and the detected value of the voltage detector 11 is compared with the set point of a detection level setting device 13 by a momentary power interruption detection circuit 13 to detect the momentary power interruption. When the momentary power interruption occurrs, then if devices are under regenerative operation, the self-arc-suppressing switching element 8 is turned OFF just during the momentary service interruption and regenerative current is broken. In this manner, even if the commutation failure of the thyristor converter 3 is caused, short-circuit current is not generated.

Filed: 1978-06-12
Abstract: PURPOSE:To obtain a micro-miniature head and prevent choking of its orifice by abruptly gasifying liquid and letting the same spout from the nozzle in an ink on demand system. CONSTITUTION:Ink 23 in an ink well 24 communicates with the ink chamber 22 of the housing 16 of a head 25. The heating element 17 near an orifice 21 is sandwiched by an electrode 18 and is thereby energized. The ink then gasifies and causes volume expansion. part of the ink near the orifice 21 becomes a gas 26 which forces out the ink 27. As the gas temperature rises upon rising of the temperature of the heating element 17, the gas 28 spouts out and at the same time ink particles 29 are also injected. At the same instant of jetting out of the ink particles 31, the gas 30 absorbs the energy of the heating element 17 and is released to the outside, resulting in that the orifce 21 maintains balance with the outside pressure under surface tension as with the end 32 of the ink.

Title: Graphic processing device and method
Inventor: SATO KOICHI
IPC: G06T7/60
Filed: 1999-03-16
Abstract: PROBLEM TO BE SOLVED: To improve the efficiency of drawing a graphic form including a curve by deciding whether a polygon including control points showing a curve as vertexes is convex to the axial direction vertical to a scanning line and then deciding whether a graphic form of the contour data is convex to its axial direction. SOLUTION: When a graphic form that is shown by the graphic contour coordinate data consists of a straight line AB, a straight line BC, a curve CF, a straight line FG and a straight line GA, the identifier of the curved part of the graphic contour coordinate data is replaced by straight line identifiers. Thus, a polygon A-G is obtained. That is, the part of the curve CF is turned into the straight lines CD, DE and EF by using the control points D and E. Then a Y axis direction convexity decision means decides whether the polygon A-G is convex to the Y axis direction. Thereby it is not required to approximate a curve part of a graphic form by many straight lines when it is decided whether the graphic form is convex to the Y axis direction.
