    Abstract: A pickup cartridge composed of a cantilever, a plate-shaped armature and a magnet or magnetic material. The plate-shaped armature is pivotally mounted to the cantilever and stretched backward by a suspension wire through a damper disposed in front of the magnet or magnetic material. A holding means is disposed at the rear of the damper and includes a magnet with north and south poles. Coils are mounted on the armature. The magnetic flux which passes through the coils passing in the direction of the axes of the coils, but not parallel to the direction determined by a line between the north and south poles of said magnet, produces a linear push-pull output.

    Abstract: Proposed are a composite material having a high adhesiveness, wherein non-penetrating pores that are formed in a silicone surface layer are filled up with a metal or the like without leaving any voids by using the plating technique and the silicone surface layer is coated with the metal or the like, and a method of producing the composite material. A composite material, which has a high adhesiveness between a second metal or an alloy of the second metal (106a, 106b) and a silicone surface, can be obtained by filling up non-penetrating pores that are formed in the surface of a silicone substrate (100) substantially with a second metal or an alloy of the second metal (106a) with the use of the autocatalytic electroless plating technique wherein a first metal located at the bottom of the non-penetrating pores as described above serves as the starting point, and coating the surface of the silicone substrate (100) with the second metal (106b).
