  • Patent number: 7310199
    Abstract: An apparatus which provides improved fluidic control includes a circumferentially extending windage plate adapted for placement adjacent a rotatable disc surface. The plate operates to direct fluidic currents established by rotation of the surface. One or more snubber members are supported by the plate to prevent localized contact between the plate and the surface as a result of deflection induced by application of a mechanical shock. Preferably, an access element is moveable along a movement path adjacent the rotatable surface. An air dam comprising a localized increased thickness portion of the plate at a leading or trailing edge of the plate preferably further directs the fluidic flow, and the snubber member-further prevents contact between the air dam and the rotatable surface. The rotatable surface preferably comprises a data recording surface and the access element preferably comprises a data transducing head.

  • Patent number: 7310200
    Abstract: An apparatus separating a resonance excitation response of a first disc from a resonance excitation response of second disc, the apparatus includes spindle motor with a spindle motor hub supporting the first disc, a disc spacer communicating with the first disc supporting a second disc and a clamp ring attached to this on the motor hub imparting a clamping force on the second disc to form a disc pack. Separation of resonance response between the first disc and the second disc results from maintaining a distinction between an amount of extension of mass and stiffness of each disc available for resonance excitation beyond respective outboard clamping points of the disc spacer. Separation of resonance assures resonance of the first disc is dissipated by a damping of the spindle motor, as well as resonance of the second disc is dissipated by the damping of the spindle motor.

  • Patent number: 7310204
    Abstract: A magnetic head for writing information on a relatively-moving medium has a pair of substantially flat soft magnetic pole layers separated by a pair of coil layers. A soft magnetic pedestal adjoins the leading pole layer adjacent to a medium-facing surface and is spaced from the second pole layer by a nanoscale nonferromagnetic gap, the pedestal having a layer of high magnetic saturation material that defines a throat height and extends beyond the throat height. A second high magnetic saturation material adjoins the trailing pole layer and either terminates at the throat height to form a second pedestal or extends to reach a magnetic backgap structure that magnetically couples the pole layers. The MR sensor can be located closer than the write transducer to the trailing end of the head to reduce separation between the read transducer and the write transducer.

  • Patent number: 7310215
    Abstract: A tunable element in the microwave frequency range is described that may include one or more tunable elements that are directly digitally controlled by a digital bus connecting a digital control circuit to each controlled element. In particular, each digital signal is filtered by a digital isolation technique so that the signal reaches the tunable elements with very low noise. The low noise digital signals are then converted to analog control voltages. The direct D/A conversion is accomplished by a special D/A converter which is manufactured as an integral part of a substrate. This D/A converter in accordance with the invention may consist of a resistor ladder or a directly digitally controlled capacitor. The direct digitally controlled capacitor may be a cantilevered type capacitor having multiple separate electrodes or sub-plates representing binary bits that may be used to control the capacitor.

  • Patent number: 7310222
    Abstract: A flat-panel display with fixtures in its sidewalls to enable support by lateral mounting members is disclosed. The advantage of this approach, in which the fixtures are essentially rotated around to the sides of the flat-panel display, is the reduction in the portion of the portable computer's top cover that is not the active display. In practice, this results in an increase in the size of the display that may be housed in the same-sized top cover. In order to accommodate the lateral mounting of the flat-panel display, metal brackets are used. These brackets extend from the base unit hinges and cradle the display. This adds torsional rigidity, but also removes the requirement that the back must be structural. Further reductions in the inactive portions of the top cover may be achieved by extending the ends of the display's fluorescent back-light beyond or through the metal rim that surrounds the display.

  • Patent number: 7310246
    Abstract: A capacitor charging circuit does not include a Zener diode and makes it possible to integrate a large number of circuits and elements within a semiconductor integrated circuit. The capacitor charging circuit includes a flyback transformer having a primary coil, a secondary coil, and a tertiary coil, a switching element that turns the current that flows through the primary coil on and off, a capacitor that is charged by a current produced in the secondary coil through the on-off action of the switching element, and a charge control circuit that controls the on-off action of the switching element. When the switching element is off and a voltage produced at a first end of the tertiary coil is larger than a reference voltage corresponding to the predetermined voltage of the charge voltage of the capacitor, the on-off action of the switching element is stopped.

  • Patent number: 7310247
    Abstract: The present invention discloses a method for controlling transformer excitation cycles and a circuit for controlling the same, wherein the excitation cycle and the demagnetization cycle, which determine the rise and fall of the excitation current, are modified to prevent the coil from being saturated. In the present invention, a sense current is acquired from the excitation current of the transformer coil, and a demagnetization reference value is set. The sense current is used to determine whether the excitation current is lowered to the demagnetization reference value in the demagnetization cycle. A cycle modifying circuit is used to modify the duty cycle signal output by a pulse control unit until the excitation current is lowered to a preset level.

  • Patent number: 7310248
    Abstract: A switching power supply for achieving a constant current drooping characteristic of sufficient accuracy with low cost and the minimum number of components. In the switching power supply, a secondary duty limiter circuit outputs a clock signal from the time a switching element is turned off until the time the on duty of secondary current, which starts flowing to a secondary winding of a transformer, is fixed at a predetermined value. A clock signal selector circuit selects and outputs the clock signal when a load increases and the on duty of the secondary current reaches the predetermined value. Consequently, when the load increases, a direct current output voltage decreases and an output characteristic becomes a constant current drooping characteristic.
