  • Patent number: 7135647
    Abstract: A keyboard has a base plate, a membrane sheet, a housing, a key-top, a link mechanism disposed between the housing and the key-top, and a switch operating member disposed under the key-top and operated by the key-top. The housing, the membrane sheet and the base plate have slits at a position corresponding to a surrounding portion of the key-top. Consequently, the distance between the key-top and the housing can be decreased even if the skirt part of the key-top is long. Furthermore, the slit of the housing is formed as a discontinuous annular shape to surround the link mechanism, and the surrounding portion of the key-top has a slit corresponding to the bridge shaped portion of the housing.

  • Patent number: 5644449
    Abstract: A magnetic head slider assembly for a magnetic recording and reproducing apparatus. A first slide surface and a second slide surface, which are comparatively wide, are formed on the surface of the assembly which will face a recording medium. A first air groove intervenes between the first and second slide surfaces. Part of the first slide surface is formed by a magnetic core. A third slide surface adjoins the first slide surface via a second air groove at the side opposite to the first air groove. The third slide surface is slightly remoter from the medium than the first and second slide surfaces.
