  • Patent number: 8711520
    Abstract: In one embodiment, a method of manufacturing a magnetic disk includes rotating a magnetic disk, supporting a floating head on the rotating magnetic disk, the floating head having a slider body and an element unit formed on a trailing edge of the slider body, contacting a floating surface of the slider body with the magnetic disk, and protruding a portion of the floating head toward the magnetic disk due to application of power to a heater element within the element unit, wherein the element unit is positioned away from the magnetic disk. In another embodiment, a floating head includes a slider body comprising AlTiC, an element unit positioned on a trailing edge of the slider body, the element unit having an initial recess amount of at least about 4 nm, and a heater element positioned within an alumina protective film of the element unit.

  • Patent number: 7536590
    Abstract: A programmable controller has a first (executing) CPU unit and a second (standby) CPU unit for a duplexed operation. Each CPU unit stores CPU version indicating its functionality and function version indicative of the functionality of the user program stored in itself. Before the duplexed operation is started, the first CPU unit acquires the unit version of the second CPU unit, compares it with the function version stored in itself and judges from this comparison whether a duplexed operation is possible or not. Only if it is judged that the duplexed operation is possible, the first CPU unit copies the user program stored in itself to the second CPU unit together with the function version and the duplexed operation is started.

  • Patent number: 7269329
    Abstract: An optical waveguide plate for a surface light emitting apparatus and a surface light emitting apparatus using the optical waveguide plate that provides excellent uniformity in surface emission is disclosed. The optical waveguide plate comprises an end face introducing light emitted from a light source, and a light emitting surface outputting light introduced from the end face. The end face has a light introducing portion comprising a plurality of notched prisms which disperse incident light. The intervals between two adjacent prisms are set to become greater in proportion to the distance from the center of the light introducing portion. The angles of the prisms are also adjusted to provide uniform surface emission.
