  • Patent number: 7967662
    Abstract: An apparatus for lapping sliders comprises a rotatable lapping plate for lapping elements that are to be formed into sliders, a pushing force adjusting member that has an internal space therein and that extends vertically along an lapping plate axis that is perpendicular to the lapping plate, a pusher for pressing the elements, the pusher being connected to the pushing force adjusting member, and gas supply means for supplying a gas into the internal space, the gas supply means being connected to the pushing force adjusting member. The pushing force adjusting member comprises a first part that includes a connection with the pusher, a second part that includes a coupling between the internal space and the gas supply means, and an axially deformable part that is located between the first part and the second part.

  • Patent number: 7768281
    Abstract: A probe assembly used to lap a bar, the bar being provided with elements that are to be formed into sliders, is provided. The probe assembly comprises an elastically deflectable probe, and a stopper for applying bending deformation to the probe so as to cause first bending deflection at a leading end of the probe and for maintaining the first bending deflection of the leading end while preventing a bending deformation at the leading end from becoming smaller than the first bending deflection. The leading end of the probe is adapted to be subjected to second bending deflection that is larger than the first bending deflection in a same direction as a direction of the first bending deflection and thereby to abut against an electrode pad to establish electrical connection between the probe and the electrode pad, the electrode pad being provided on a surface of the bar other than a surface to be lapped.

  • Patent number: 7645182
    Abstract: An apparatus for lapping a slider comprises a lapping head for supporting elements while pressing the elements against a rotating lapping plate, the elements that are to be formed into sliders, a holding mechanism for supporting the lapping head, the holding mechanism having a first engaging member that extends in a vertical direction, a base for supporting the holding mechanism, the base having a second engaging member that extends in the vertical direction, wherein the second engaging member is engaged with the first engaging member to form an internal space therebetween, and a decompressing mechanism for decompressing the internal space. The holding mechanism is subjected to vertically upward force from the decompressed internal space in order to be movably supported by the base in the vertical direction.

  • Publication number: 20040255841
    Abstract: Layers of slurry of dielectric powder are deposited one after another on a substrate through jet print technology to constitute a shaped article of dielectric layers. A predetermined region of the shaped article is bound with a binder to construct a photonic crystal having a three-dimensional structure. The jet print technology is free from limitation on the materials to be used therein, and broadens the configuration latitude in the photonic crystal produced. Photonic crystals having a controlled dielectric constant are easy to obtain through the technology.
