A flash NAND type EEPROM system with individual ones of an array of charge storage elements, such as floating gates, being capacitively coupled with at least two control gate lines. More particularly, the invention relates to a process for hydroprocessing a catalytically cracked light cycle oil, and then re-cracking in an out-board FCC reactor it in order to form a naphthenic blend-stock. The input stage includes a first circuit including a plurality of transistors and a complimentary circuit including a plurality of transistors. The acoustic matching member is configured to conduct the received ultrasonic wave to the piezoelectric element.
