Patent JP-H03249478-A (JP)
Title: Agricultural vehicle
Inventor: ISHIDA ISAO
IPC: F16H59/56
Filed: 1990-02-23
Abstract: PURPOSE:To prevent an accident of falling during unloading from a truck or during running on a steep slope by providing a linkage means for actuating an unload valve in association with the operation of a manipulating member for a clutch, and a change-over means for effecting and releasing the function of the linkage means. CONSTITUTION:When a clutch is changed over, an unload valve is actuated through the intermediary of a linkage means 51 so that an output side circuit of an HST (hydraulic stepless transmission) 30 is short-circuited. Accordingly, even though the rotation of an input shaft 43 comes to a stop, an output shaft races so as to prevent a vehicle from abruptly stopping during running on a road. Further, during an unloading from a truck or the like, the change-over means 51 releases the function of the linkage means 51 is released, thereby it is possible to prevent wheels from racing upon disengagement of the clutch so as to ensure safe operation.

Title: Pachinko game machine
Inventor: ICHIHARA TAKAAKI
IPC: A63F7/02
Filed: 1999-02-23
Abstract: PROBLEM TO BE SOLVED: To make determinable a second benefit by a game in which a game player participates and to pleasantly play a game. SOLUTION: Regarding the pachinko game machine imparting a first benefit to a game player when a big hit is made during a game, a benefit determining game is performed during a big hit game or a normal game. This benefit determining game is realized by a benefit determining processing. For instance, when a game ball passes a gate 202a, the level (a game state) of a level meter 184 is increased and is recorded, and when the game ball passes a gate, the level is decreased and is recorded. When the level recorded in this way becomes a reference value 184a or more, a rotating body (movable body) 182 is rotated to the right which is advantageous to the game player. When the level becomes less than the reference value 184a, the rotating body 182 is rotated to the left side which is disadvantageous to the game player.  Because the game state is changed by a benefit determining game in which the game player participates and a second benefit is determined, the game player can pleasantly play a game.
