Abstract: A data storage disk drive is provided with a spindle which supports a plurality of disks having at least one magnetic disk surface to form a spindle assembly for rotation of the disk surfaces about a common axis and a rotary actuator which supports magnetic transducers for movement in unison about respective disk surfaces. The disk drive includes a disk drive enclosure having die-cast generated predetermined zero draft geometries for mounting the spindle motor shaft and the actuator bearing shaft. The enclosure includes a base casting and a cover casting, each casting including structure for locating and retaining electrical connectors used for connecting to a planar electronics card located outside the drive enclosure. The disk drive includes an effective and easily manufacturable electrical path from a flex circuit to an actuator comb. The disk drive includes a tubular chemical breather filter arranged with integral housing and diffusion channels formed in the cover casting.

Abstract: A lever and latching arrangement having a pair of camming surfaces disposed on one end thereof is attached to one end of a tailstock member of an electronic memory book or central electronic complex book of a computer. This lever arrangement, as rotated about a pivot axis, engages one of the camming surfaces with a portion of the computer frame; the mechanical advantage of the lever system overcomes the large forces required to connect or disconnect the electronic book from the computer connectors. The pivot axis is positioned between the side rail of the book and the computer frame and between the tailstock and the connectors of the book to afford a low profile relative to the tailstock, permitting a more efficient use of available volumetric space within the computer.

Abstract: The present invention is directed to an electrical connector 10 having a housing 12 with at least one electrical contact 22 positioned therein. The electrical contact 22 is adapted for electrical engagement with an electrical wire 42 to be positioned within the housing 12. A spring 16 has a fixed end 17 and a free end 18, the fixed end 17 of the spring 16 is used to secure the spring 16 in the housing 12. The free end 18 of the spring 16 is positioned adjacent a tool opening 20 formed in the housing 12. The free end 18 of the spring 16 is adapted to be directly engaged by a tool 13 to be inserted through the tool opening 20 in the housing 12. The free end 18 of the spring 16 further comprises a plurality of retention tabs 35, 36, 37 formed thereon that are adapted for engaging the tool 13 when the tool 13 is inserted into the housing 12 to deflect the spring 16 and thereby allow the insertion of an electrical wire 42 into the connector 10 adjacent the electrical contact 22.
