Title: Gas laser
Inventor: SUGIYAMA TSUTOMU
IPC: H01F41/06
Filed: 1990-06-12
Abstract: PURPOSE:To enhance the reliability of a high voltage power source and stabilize output power by specifying winding tensile force called for when winding up the secondary coil of a step-up transformer. CONSTITUTION:The winding tensile force of a wire for a secondary coil of a step-up transformer 12 is set so that it may range from 30 to 40% of breaking tensile force of the wire. When the winding tensile force is less than 20% of the breaking tensile force of the wire, the variability of its distributed capacitance is increased while the average value rises as well. When it exceeds 50% of the breaking tensile force, the wire in the upper layer enters between the wires in the lower layer, which reduces a wire to wire distance practically and increases the distributed capacitance. In this case, the wire is wound by 35% of the breaking tensile force, which protects the wire coating from damage. This construction makes it possible to maintain dielectric strength in the step-up transformer 12 and a rectifier diode 13 and hence enhance the reliability of the step-up transformer 12. Furthermore, the variability of the distributed capacitance can be minimized so that the variability of the output characteristics may be reduced, thereby enabling the stabilization of the output voltage.
