Abstract: An apparatus for the protection of signal copy for prevention unauthorized copying of music software such as records, compact discs and music tape by recording is arranged such that when recording audio signals on a medium, certain supplemental information is added to the audio signal to be recorded, and in the process of copying by reproducing this medium, when the supplemental signal is detected in the reproduced signal, the copying action is stopped to protect it from being copied.

Abstract: An impact energy steering wheel comprising a ring portion, at least one plastically deformable spoke core member, a boss portion, and a plastically deformable support member supporting an impact energy absorber and a pad. The support member is fixed to each of the spoke core members such that the support member, the energy absorber, and the pad are positioned so as to be spaced apart from and between the ring and the boss portions. When a generally horizontally acting impact force acts on the ring portion, the spoke core members are subjected to plastic deformation and the ring portion reorients so as to have an imaginary frontal plane extending in the vertical direction. The support member, being attached to each of the spoke core members, is affected by the deformation of these spoke core members and reorients so as to cause the impact energy absorber and the pad to have upper surfaces which extend in the vertical direction parallel to the ring portion imaginary frontal plane.

Abstract: A steering wheel is provided with a core of a ring portion, a boss disposed at the center of the core of the ring portion, and cores of a spoke portion disposed between the core of the ring portion and the boss. A first deformable member is interposed between the boss and cores of the spoke portion so as to couple the boss with the cores of the spoke portion, and is provided with a plurality of arm portions which extend radially from the boss and can be plastically deformed. Further, a second deformable member is fixed to the boss at the upper side or lower side of the first deformable member, and abuts on the first deformable member in the deformed state of the first deformable member and then is plastically deformed.

Abstract: A steering wheel horn switch system including a pad mounted in a steering wheel and having a pad leg; a pad leg receiver (5) for the pad leg; a pushup spring (3, 31) arranged concentrically with the pad leg receiver and against whose force the pad leg receiver is pushed down; a contact plate (4, 100) with a terminal (43, 46, 101); and an electrode plate (2', 20, B) with which the terminal of the contact plate comes into electrical contact when the pad is depressed and thus the pad leg receiver is pushed down.
