A displaying device comprises an outer rotational member and an inner rotational member. The displaying device is incorporated with a game machine. The outer rotational member of the displaying device is rotated in a lateral direction of the game machine. The inner rotational member is rotated in a perpendicular direction of the game machine. The rotational members are rotated in the different directions with each other, and are respectively stopped. After the rotational members have been stopped, a game result is determined in accordance with a stop state of the rotational members. The outer rotational member represents a dividend of the game, and the inner rotational member represents whether the game is a win or loss.

Crossbow bowstring drawing mechanisms which are integrated into or secured in the crossbow handle and which provide a straight and balanced draw to the crossbow bowstring to cock the crossbow bowstring in position in the crossbow trigger mechanism ready for firing. The cocking system can be manually operated or motorized, and can be manufactured as part of a crossbow or retrofit into a crossbow. An internal or external source of rotational power, such as hand crank, power screwdriver or an electrical motor, is preferably utilized in conjunction with a claw member including a bowstring engaging portion to translate rotation of the input source to longitudinal movement of the claw member to draw or release the crossbow bowstring resulting with minimal effort being expended by the user. The claw member may include adjustable cams used to center the claw member with respect to the crossbow barrel.

A brushless disk DC motor that exhibits high power density and light weight and is capable of power regeneration and reverse operation employs a flat circular non-ferrous stator plate having a plurality of electromagnets mounted in a ring pattern on an inner face thereof. Permanent magnets are mounted in equal numbers in inner and outer ring patterns on the outer and inner cylindrical surfaces, respectively, of a pair of steel rotors of different diameter that rotate in concert. The stator plate and the pair of rotors are axially aligned such that the inner and outer rings of permanent magnets rotate adjacent to and inside and outside, respectively, the ring of electromagnets. The electromagnets utilize tape-wound amorphous metal cores to minimize eddy currents and resultant iron losses and to permit the use of heavier gauge copper windings to minimize resistive power losses. A greater number of poles in the form of permanent magnets can be accommodated, the number being limited only by the diameter of the rotor, thus providing increased power and torque over prior art brushless DC motors having a limited number of poles. The present motor exhibits up to 200% more starting torque, thus eliminating the need for a gear box or clutch in electric vehicle applications.

The superconducting field windings are formed from a High Temperature Superconducting (HTS) material such as BSCCO-2223 or YBCO, for example. The double rotor assembly configuration provides a new technical effect over conventional rotating superconducting machines having a single rotor assembly.
