  • Publication number: 20070065245
    Abstract: A hand power tool, having a housing (12) and a tool bit (15), in particular a metal-cutting tool bit, as well as having a guard means (22), which embraces the tool bit (15) and is coupleable to the housing (12) and axially adjustable relative to it, is made easy to manipulate in setting the cutting depth by providing that the housing (12) and the guard means (22), in a first adjusting position, are positionable axially freely and in a second adjusting position, in particular guided by adjusting means, are positionable axially finely adjustably to one another, in particular lockably.

  • Patent number: 6094803
    Abstract: A method of making and self-aligning a disk data storage read/write head that uses a catadioptric focusing device (or lens) having a high numerical aperture (NA), which does not introduce significant spot aberration on a storage medium. The manufacturing process of the head is carried out at a wafer level, and is facilitated significantly by the flatness of the focusing device. An exemplary manufacturing process is implemented as follows: A lens coil/plate is formed by molding a flat optical substrate to form the desired lens shapes. Coil cavities or depressions are formed simultaneously with the lens to accommodate a coil. Conductive plugs are formed in proximity to cutting lines for wire bonding attachment to the coil. A slider wafer is formed and bonded to the lens/coil wafer. Coils and pedestals are also formed on the lens/coil plate using thin-film processing techniques, and reflective surfaces are deposited on the bottom surface of the substrate, opposite the lens.

  • Patent number: 6016290
    Abstract: A read/write head for use in data storage drives includes a thermally assisted inductive write section and a magnetic read section to write data onto, and retrieve data from a storage medium. The write section includes a waveguide formed of a core and a surrounding cladding, and positioned between a first write pole and a second write pole, to conduct a laser beam for heating the medium. The second write pole and the optical waveguide core are offset relative to each other at the pole tip, such that they define an overlap region that determines a written track width. The offsetting facilitates manufacturing process since the optical waveguide core and the second write pole can be made wide enough while still defining tracks with a limited width.

  • Patent number: 4592797
    Abstract: A tool for finishing joints in wall board employs a generally cylindrical roller for applying pressure to imbed the tape in adhesive supported on a handle for applying pressure to the roller by a yoke rotatably supporting the roller in spaced locations along the roller axis. An adhesive trowel member is also supported on the yoke and provides an opening through which the roller projects. The trowel is positioned generally tangent to but slightly below the roller surface so that the trowel presents a curved surface of much greater radius than the roller and acts to redistribute the adhesive. A box scrapper also supported from the yoke about an axis parallel to the roller axis has a base and sidewalls, except on that side adjacent the roller. That particular side is left open to accumulate adhesive scrapped off the wall. The sidewalls are made to terminate in a common plane permitting flat contact with the wall and together act as a scrapper to collect adhesive in the box.
