摘要： In accordance with various embodiments, a printed structure of a flex circuit assembly includes a plurality of adjacent land portions formed on a heat conductive stiffener member and which support electrically conductive paths for connection to an integrated circuit. A corresponding plurality of separation channels are formed between the adjacent electrically conductive paths, and thermal energy generated by operation of the integrated circuit is transferred through the separation channels to the stiffener member. In some embodiments, the separation channels retain a fluid, such as air or a low density inert gas, which flows through the separation channels in response to rotation of a rotatable member adjacent the flex circuit assembly. In other embodiments, a dielectric, thermally conductive material fills the separation channels.

摘要： An interface to make interconnections between the interior and exterior of a sealed enclosure may include a flat connector (FC). The FC may comprise at least one layer of a substantially planar substrate. Each substrate layer may include metallization for conducting signals between contacts on an interior-facing surface and contacts on an exterior-facing surface. In an enclosure with an aperture for passing electrical conductors, the FC may be configured to seal the aperture to inhibit the escape of a low density gas, such as helium, for a long period of time. In one embodiment, the FC may include metallization configured to minimize helium leakage. As such, the FC may conduct electrical signals into and out of the sealed enclosure. Such signals may include, for example, power, control, and data signals for operating devices housed within the enclosure.

摘要： 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.

摘要： An adjustable, battery-powered, constant pressure gun for dispensing viscous materials such as caulk and adhesive. The gun includes a housing having a handle, an operator-actuated trigger, and a battery compartment with power supply terminals. A motor mounted within the housing drives a dispensing mechanism. The flow of current through the motor is controlled by an electronic switch. A current-to-voltage converter including a low-pass filter is coupled to the motor and provides a feedback pressure signal representative of the actual dispensing pressure as a function of the current drawn by the motor. A set-point voltage signal representative of a desired dispensing pressure is provided by an operator-adjustable pressure control. A hysteresis comparator connected to the electronic switch compares the feedback pressure signal to the set-point signal, and controls the switch as a function of the comparison to maintain the actual dispensing pressure within a predetermined operating band of the desired dispensing pressure when the trigger is actuated.
