Abstract: PURPOSE:To obtain a lighting device for a discharge lamp which has good starting performance and restarting performance by generating a high-pressure pulse voltage for a certain period. CONSTITUTION:A closed circuit consists of a high-pressure discharge lamp DL, the secondary winding of a pulse transformer Tr and a primary capacitor C1, and the primary capacitor C1 is connected in parallel to the output of an inverter circuit 1 which is fed by an input power supply E, and a secondary capacitor C2 which is charged with the voltage obtained by means of boosting the output of the inverter circuit 1 intermittently and rectifying it, a discharging gap G, and the primary winding of the pulse transformer Tr constitute the closed circuit. Then the capacitor C2 which works for generating a high-pressure pulse voltage is charged with the voltage obtained by intermittently boosting the output of the inverter circuit 1 and rectifying it. Thus, for a period when charging the capacitor C2 which works for generating the high-pressure pulse voltage is paused, the voltage which promotes a switch to arc discharge can be applied to the high-pressure discharge lamp DL by means of the output of the inverter circuit 1 so that its starting characteristics and restarting characteristics can be improved.

Abstract: PURPOSE:To prevent the lowering of insulating capacity by applying a thermosetting resin solution to which at least one kind of a chelating agent selected from a triazine derivative, a triazole derivative and a hydrazide derivative to a metal plate or copper foil and drying the formed layer to form the metal plate or copper foil having an insulating layer. CONSTITUTION:The copper ion generated by continuously applying voltage across a copper foil 1 and a metal plate 3 at high temp. or under a high temp. and high humidity condition is converted to a chelate compound by a chelating agent to suppress the generation of a dendrite. By this method, the lowering of insulating capacity can be prevented and a metal base copper clad laminated sheet enhanced in reliability is obtained. The chelating agent is added to a solution prepared by diluting a thermosetting resin with a solvent to be uniformly dispersed therein. An insulating layer 2 is formed by applying a thermosetting resin solution to the copper foil 1 or the metal plate 3 and drying the formed layer. The metal plate 3 or the copper foil 1 is laminated to the coated one to produce the laminated sheet.

Title: Three-phase balancing unit
Inventor: KAMITSURA AKITAKA
IPC: H02J3/26
Filed: 1994-07-22
Abstract: PURPOSE:To eliminate the need of harmonic compensation by extracting a basic wave component free from harmonic component from a detected three- phase AC current through a filter and then detecting the reverse phase component of fundamental wave through a three-phase/two-phase conversion circuit and a two-phase/three-phase conversion circuit using the three-phase basic wave AC current thus extracted. CONSTITUTION:Band-pass filters 11-13 extract the fundamental wave components iuf, ivf, iwf from a three-phase AC current detected through a current detector. A three-phase/two-phase conversion circuit 2 converts the positive phase component of the fundamental wave into a DC and a rotating coordinate transforming circuit 3 converts the reverse phase component 9 of the fundamental wave into a double frequency component. High-pass filters 41, 42 extract the reverse phase component of the fundamental wave which is then converted into three- phase by a rotating coordinate inverse transforming circuit 5 and a two-phase/ three-phase conversion circuit 6 thus detecting the reverse phase component of the fundamental wave. Since the harmonic compensation is not required, the capacity required as a balancing unit can be determined easily.
