An electric-motor-equipped vehicle of the present invention includes an electric motor which receives a power supply from a storage apparatus and drives the vehicle, or assists a driving of the vehicle by an internal combustion engine. For each of the plurality of step voltages, different digital values are allocated to different steps of the step voltage. The light is totally reflected at those reflection faces which are not immersed in the liquid but refracted into the liquid at immersed reflection faces. In other embodiments indicia are provided as quick response codes, and as various markings to indicate compatibility of the medical device with ethanol. The floating gate transistor provides a dense and planar dynamic electrically alterable and programmable read only memory cell adapted for uses such as for a dynamic random access memory or a dynamically refreshed flash EEPROM memory. The alternative clevis arrangement is inherently balanced and can meter fuel through multiple nozzle orifices simultaneously.
