Microtran's product line and client base were purchased by Tamura Corporation of America in 1994. Tamura has been a subcontractor for Microtran for at least five years and had manufactured several of the Microtran products prior to this acquisition. Tamura has merged identical and comparable goods into a single product that has both the Tamura and Microtran part numbers after the acquisition. Tamura has been able to continue to serve clients whose designs solely referenced the Microtran component number thanks to this ""dual marking.""
