Toyota Crown own unique insignia for the model line with the current Crown having a stylized crown emblem on the grille and steering wheel along with inspiring the names of its smaller progenitors. 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. The Avalon (the Crown's North
Townsend discharge discharge sets the upper limit to the blocking voltage a glow discharge gas-filled tube can withstand. This limit is the Townsend discharge breakdown voltage, also called ignition voltage of the tube. The occurrence of Townsend discharge, leading to glow discharge breakdown shapes the current-voltage characteristic of a gas discharge tube such as a neon lamp in a way such that it has a negative differential resistance region of the S-type. The negative resistance can be used to generate electrical oscillations and waveforms, as in the relaxation oscillator whose schematic is shown in the picture on the right. The sawtooth shaped
