The present invention relates to a multilayer piezoelectric transformer that uses a composite resonant vibration mode for step-up voltage conversion. A flow barrier is provided in the funnel that controls vapor release from a fuel canister and allows for refueling of liquid fuel without touching the apparatus. An outer wall is spaced apart from the base and is secured to the base by and adjoins with the first and second sidewalls. The game controller randomly selects the fractional image to display in each display section.
