Title: Power supply apparatus
Inventor: MATSUI KAZUAKI
IPC: H02J1/00
Filed: 2000-08-28
Abstract: PROBLEM TO BE SOLVED: To surely suppress a rush current which flows into a smoothing capacitor, when a power supply is re-closed or recovered, even if a cut-off or a short break is produced in an external AC power supply. SOLUTION: A rectifying bridge circuit 1 rectifies an external AC power supply E and charges a smoothing capacitor C via a rush current preventing resistor R. A 1st switch SW3 is connected, in parallel with the resistor R. A load DC power is supplied to a load 3 by the repetition of charge/discharge of the smoothing capacitor C. A delay drive means 7 turns on the 1st switch SW3 to short-circuit the resistor R, after the external AC power supply E is closed. A switching control means 9 turns off the 1st switch SW3 to release the connection with the resistor R, when the cut-off or short break of the external AC power supply E is produced.

Title: Double counterposed spark discharge gaps
Inventor: KATO GIICHIRO
IPC: H01T4/02
Filed: 2000-07-30
Abstract: PROBLEM TO BE SOLVED: To prevent a sparking electrode itself from being damaged by preventing the dynamic current of spark discharge gaps, and to prevent deterioration of inter- electrode insulating resistance in advance. SOLUTION: This double counterposed spark discharge gaps have a pair of counterposed electrodes slightly projecting between spark discharge gaps formed by a pair of counterposed solid electrodes (for example, square pole-shaped electrode or the like) and directly or indirectly integrating them, and the outer opposed faces are located within the range of the ionizing action of inner counterposed faces as a main element of this spark discharge gaps.  The discharging is started mainly at a central pat of the internal electrodes, the arc is expanded to the outer electrode faces having a wide clearance and a large counterposed area by the explosive force and the ionizing action from the central part, and the stronger discharging current is induced, but the spark receives the cooling action in this space, whereby the ionizing (thermal ionization) is prevented, and the arc-extinguishing tends to occur readily. In a case of an AC power source circuit, the fall of potential of the electrode faces is high, and the diffusion of ion is much, so that the restriking can be prevented and the arc is distinguished during approximately half a cycle, even if the dynamic current is produced.
