Abstract

This disclosure relates to flash fusers for use in a xerographic or electrographic reproducing machine. Piezoelectric ceramic transducers (PZT) are capable of very high output pulse voltages (in the KV region). They are presently used for ignition purposes in cigarette lighters, appliance ignition (gas) systems, and I.C. engines. They are reliable with low UMC (about $2.00). A Xenon triggering system has a UMC of 10 to 20 times greater, when using the typical SCR capacitor discharge transformer approach. The PZT element can be excited by either a machine cam (mechanical) or by an electrical impulse in a magnetostrictive coil and core assembly.

This disclosure relates to flash fusers for use in a xerographic or electrographic reproducing machine.

Piezoelectric ceramic transducers (PZT) are capable of very high output pulse voltages (in the KV region). They are presently used for ignition purposes in cigarette lighters, appliance ignition (gas) systems, and I.C. engines. They are reliable with low UMC (about $2.00). A Xenon triggering system has a UMC of 10 to 20 times greater, when using the typical SCR capacitor discharge transformer approach. The PZT element can be excited by either a machine cam (mechanical) or by an electrical impulse in a magnetostrictive coil and core assembly. Accordingly, this disclosure contemplates the use of a PZT for triggering a flash fuser power supply. 0
