A method, system, and computer software product for capturing and distributing memories of a deceased individual. A differential mechanism is provided between the rotary cylinder and the spool changing-over member for integrally rotating the rotary cylinder and the spool changing-over member when a steering force applied to the steering shaft is low, and allowing a relative rotation between the rotary cylinder and the spool changing-over member when the steering force is larger than a predetermined value. In one embodiment, when the well is pressurized the tool can be loaded with one or more items to be dropped. An injection hole is positioned on an imaginary plane, which contains the central axis of the sector-shaped spray along the injection direction and is orthogonal or approximately orthogonal to the sector-shaped spray. The end pole magnet has magnetic orientation opposed to the first direction. A beverage container holder is mounted on the armrest pad, and can used for supporting a beverage container when it extends forwardly from the armrest pad and then folded and pivoted so it is underneath the armrest pad.
