The variable length code formed by the variable length coder 7 is separated into the fixed length coding part and the variable length coding part periodically at the decoder side. Thus, even if any error takes place in the communication line, most of the fixed length coding part is decoded correctly.

Title: Game ball flicking device
Inventor: FUKUSHIMA SHOGO
IPC: A63F7/02
Filed: 1995-09-14
Abstract: PROBLEM TO BE SOLVED: To provide a game ball flicking device that fine adjustment of the twist amount of a twist coil spring thereof can be performed by only one worker without requiring any special tool. SOLUTION: When a lug is turned, a cam member 58 is rotated and an adjust cam 52 presses a bow part 44 of a dislocation member 46 to be fluctuated to be dislocated pivotally around a bis shaft 39a of a retaining cap 38. Since the adjuster end 33b of the twist coil spring retained by a rectangular hole 42a is dislocated in the same direction to increase the twist amount of the twist coil spring, the flicking force is intensified. When the lug is turned in the converse direction, the twist amount of the twist coil spring is reduced to decrease the flicking force.
