A generalized approach to particle interaction can confer advantages over previously described method in terms of one or more of communications bandwidth and latency and memory access characteristics. The integrated dynamic semiconductor memory has a decoder for selecting one of the column lines and a sense amplifier which is jointly allocated to all the memory cells in a selected column line. Each backboard includes a through opening which may connect with a net mounted on the backboard to guide the ball when the ball passes through the through opening to be deposited on the water directly adjacent the rear surface of the backboard. Further, the user interfaces provide unique process of transitioning between the VOD content. The anistropic conductive adhesive film contains a binding resin having melting viscosity of 1.
