  • Publication number: 20040232426
    Abstract: A nanotube array and a method for producing a nanotube array. The nanotube array has a substrate, a catalyst layer, which includes one or more subregions, on the surface of the substrate and at least one nanotube arranged on the surface of the catalyst layer, parallel to the surface of the substrate. The at least one nanotube being arranged parallel to the surface of the substrate results in a planar arrangement of at least one nanotube. Therefore, the nanotube array of the invention is suitable for coupling to conventional silicon microelectronics. Therefore, according to the invention it is possible for a nanotube array to be electronically coupled to macroscopic semiconductor electronics. Furthermore, the nanotube array according to the invention may have an electrically insulating layer between the substrate and the catalyst layer.

  • Publication number: 20040165307
    Abstract: A hermetically sealed housing such as for use in a data storage device. The housing is formed from a pair of opposing, substantially planar first and second housing members. A gasket seal is compressed between the housing members to form a hermetic seal. A compression limit spacer limits the compression of the gasket seal to a predetermined compression level. Preferably, the gasket seal is nested within and is contactingly supported by the compression limit spacer. A plurality of fasteners secure the first and second housing members and apply a compressive force to the gasket seal. The compression limit spacer preferably comprises a plurality of discrete, spaced apart bosses through which the plurality of fasteners extend. The gasket seal preferably has a hexagonal or a c-shaped cross-sectional shape. An inert fluidic atmosphere is preferably retained within the housing.

  • Publication number: 20030147180
    Abstract: A flex cable assembly for use in a disc drive data storage device includes a laminated flex cable and a flex cable support. The flex cable provides electrical communication paths between a moveable head stack assembly and a disc drive printed circuit board. The flex cable support comprises a base and adjacent first and second flex support portions with respective first and second flex support surfaces. The flex cable is routed along the flex support surfaces and exerts a spring force thereagainst as the flex cable attempts to return to a nominally planar orientation. The direction of the second flex support surface establishes the orientation of a dynamic loop between the flex cable support and the head stack assembly. Preferably, a portion of the flex cable pulls away from the second flex support surface to lengthen the dynamic loop in response to movement of the head stack assembly.

  • Patent number: 6490190
    Abstract: A memory cell configuration has word lines and bit lines that extend transversely with respect thereto. Memory elements with a giant magnetoresistive effect are respectively connected between one of the word lines and one of the bit lines. The bit lines are each connected to a sense amplifier by means of which the potential on the respective bit line can be regulated to a reference potential and at which an output signal can be picked off. The memory cell configuration can be used both as an MRAM and as an associative memory.

  • Patent number: 6417043
    Abstract: Resistors are connected between word lines and bit lines running transversely with respect thereto. The resistors have a higher resistance than the word lines and the bit lines. The bit lines are each connected to a sense amplifier which regulates the potential on the respective bit line to a reference potential and at which an output signal can be picked off. If one of the word lines is selected and all the other word lines are put at reference potential, then the resistance of the resistor, which is assigned to an information item, can be read from the output signal.
