Abstract: A relay server computer connected to a broadcaster server computer and a content information acquisition request unit via a network includes: a content information database constructing unit that acquires content information from the broadcaster server computer to construct a content information database; a content information acquisition request receiving unit; a content information acquisition unit that searches through the content information database to acquire content information corresponding to the content information acquisition request; and a content information transmitting unit that transmits the acquired content information to a content information acquisition request unit.

Abstract: The power transmission mechanism has a first gear secured to an input shaft. A second gear connectable to the input shaft through a clutch mechanism is provided around the input shaft through a one-way clutch that allows the input shaft to rotate freely in the direction of rotation of the driving force from the engine when the clutch mechanism is in a disengaged state but does not permit rotation of the second gear relative to the input shaft in an opposite direction. A brake mechanism is provided to restrain the rotation of the second gear. A third gear is in mesh with the first gear. A fourth gear is in mesh with the second gear. The power transmission mechanism further has first to third bevel gears. The gear ratio between the first and third gears is equal to that between the second and fourth gears.

Abstract: A power transmission mechanism for use in a toy vehicle with an engine that realizes a smooth shift between a forward operation and a reverse operation with a relatively simple structure is provided. The power transmission mechanism has a first gear secured to an input shaft. A second gear connectable to the input shaft through a clutch mechanism is provided around the input shaft through a one-way clutch that allows the input shaft to rotate freely in the direction of rotation of the driving force from the engine when the clutch mechanism is in a disengaged state but does not permit rotation of the second gear relative to the input shaft in a direction opposite to the rotational direction of the driving force. A brake mechanism is provided to restrain the rotation of the second gear. A third gear is in mesh with the first gear. A fourth gear is in mesh with the second gear. The power transmission mechanism further has first to third bevel gears.
