The Corona, introduced as a smaller companion to the Crown means "crown" in Latin and was initially exported as the "Tiara", while the Corolla took its name from the "corolla" ("small crown") in Latin. The Camry's name is derived from the Japanese phrase kanmuri (冠, かんむり) meaning "little crown" and the Toyota Scepter took its name from the "sceptre", an accessory to a crown.

Electrical discharge machining (debris) to be carried away and the insulating properties of the dielectric to be restored. Adding new liquid dielectric in the inter-electrode volume is commonly referred to as "flushing." Also, after a current flow, the difference of potential between the electrodes is restored to what it was before the breakdown, so that a new liquid dielectric breakdown can occur. The erosive effect of electrical discharges was first noted in 1770 by English physicist Joseph Priestley. Two Russian scientists, B. R. Lazarenko and N. I. Lazarenko, were tasked in 1943 to investigate ways of preventing the erosion of tungsten electrical contacts
