A golf ball having a layer composed of a polyurethanepolyurea material formed from reaction injection molding a polyol component and an isocyanate component. Static analysis of the annotations can provide some of the information. The device further includes fifth semiconductor layers of the first conductivity type disposed below the second semiconductor layer or disposed at positions surrounded by the second semiconductor layer, the fifth semiconductor layers being arranged separately from one another along the first direction. A synchronizing member or member is intended to synchronize the rotational speed difference between the ring gear and one or other coupling ring.
