A low-friction conveyor including a conveyor belt supported on self-contained rollers riding along a carryway. In this mode, a write non-selection voltage applied to a non-selected memory cell next to the second selection gate transistor is switched, at least in two stages, between a lower voltage V1 than a write non-selection voltage Vm applied to other non-selected memory cells in the NAND cell unit and a higher voltage V2 than the lower voltage. In the example of address data, the handheld electronic device detects the entry of country-specific data, such as the name of the country or one of its geographic regions, and selects a corresponding data format for processing keystrokes during entry of postal codes, zip codes, or other codes. A bandage that can be applied to a bleeding wound to promote blood clotting includes a flexible substrate and a gauze substrate mounted thereon. The plated metal fingers can form a first metal gridline. The lubricant base stock comprises a first ester which is the reaction product of: a first polyol comprising at least 3 hydroxyl groups; a first mono-carboxylic acid comprising from 4 to 18 carbon atoms; and a poly-carboxylic acid comprising at least 2 carboxyl groups and comprising from 20 to 60 carbon atoms.
