A conveyance vehicle system that achieves an increased efficiency of loading an article from a conveyance vehicle into a loading opening of an automated warehouse, includes a stocker, a conveyance vehicle, and a conveyance vehicle controller. In a preferred embodiment the game includes a means for simulating a plurality of players on a game display. Fabrication of 3DS memory involves thinning of the memory circuit to less than 50 \u03bcm in thickness and bonding the circuit to a circuit stack while still in wafer substrate form. This design creates a realistic, randomly-flickering flame image above the simulated fuel source. Benefits of this invention are trays with better mass transfer efficiency and enhanced capacity compared with prior art trays.
