摘要： A method to at least temporarily replace air with an alternative gas in a first disk drive having a breather filter port is disclosed. A first disk drive is placed in a chamber, which is then evacuated to establish a sub-ambient chamber air pressure. Air bleeds out of the first disk drive through its breather filter port during a first period, until an internal pressure within the first disk drive reaches a reduced internal air pressure that is less than one third the first disk drive's initial internal air pressure. The chamber is then filled with the alternative gas. The alternative gas bleeds into the first disk drive through the breather filter port during a second period, until the internal pressure within the first disk drive reaches a restored internal gas pressure that is in the range 0.5 to 1.25 times the initial internal air pressure.

摘要： A vandal resistant adjustable metered handle assembly for a faucet is disclosed. The handle assembly includes a body having a base adapted for attachment to a sink and a sidewall extending in an upward direction with respect to the base. The base is attached to a push button handle via a stem. A spring is associated with the body and the push button handle for metering an amount of water emitting from the faucet and a sleeve is positioned between the body and the push button handle. The sleeve cooperates with the sidewall of the body to adjust the shut-off time of the metered handle assembly. The sleeve may be color-coded to indicate water temperature. The handle assembly can be made vandal resistant by adhesively securing various components together and providing an unconventional attachment member for securing the handle assembly to a sink.

摘要： A method to detect helium leakage from a disk drive enclosure is disclosed and claimed. A measurement electrical current is passed through a temperature sensor disposed within the disk drive enclosure. A reference electrical resistance corresponds to a reference temperature of the temperature sensor. A heating electrical current is passed through the temperature sensor. A heated electrical resistance of the temperature sensor, corresponding to a heated temperature of the temperature sensor that exceeds the reference temperature by at least 5° C., is determined. A value that corresponds to a quantity of helium within the disk drive enclosure is determined based on the reference electrical resistance and heated electrical resistance.

摘要： A disk drive includes a disk drive housing having a breather hole and a separate leak testing hole, both the breather hole and the leak testing hole being formed through the disk drive housing, and a drive sub-component attached to a surface of the disk drive housing so as to form an interface between the sub-component and the surface of the housing. The interface defines an interface outer perimeter and a sealed airflow testing channel in fluid communication only with the leak testing hole to enable a non-destructive detection of leaks at the interface. The airflow testing channel may be disposed within the interface outer perimeter.

摘要： A spindle motor for use in a disk drive having a rotatable head stack assembly. The spindle motor has a spindle motor hub. The spindle motor further has a magnet radially attached about the spindle motor hub. The spindle motor further has a spindle motor stator. The spindle motor has a stator rim. The spindle motor stator further has a plurality of stator teeth arrayed about and internally extending from the stator rim. The stator teeth are sized to fit about the magnet in operable communication therewith for rotating the spindle motor hub. The stator teeth have laminate layers. The stator teeth have a least one reduced height stator tooth having fewer laminate layers than a remainder of the stator teeth. The reduced height stator tooth is positionable adjacent the head stack assembly for allowing the head stack assembly to pivot over the reduced height stator tooth.
