Abstract: A method for incorporating a disk medium into a magnetic disk drive, in which the rotation center of the disk medium when a servo track information is written onto the disk medium (STW) coincides with the rotation center thereof when the disk medium is incorporated into the disk apparatus. A reference marker is provided as a positioning reference on a part of the disk medium. The disk medium is incorporated into a STW apparatus so that STW is performed on the disk medium. The disk medium is also incorporated into the magnetic disk drive in such a manner that a distance from an axis of rotation center of the disk medium to the reference marker is the same as when the STW was performed onto the disk medium.

Abstract: A toggle lever tightening device for use in the automobile industry in the assembly of automobile bodies. Toggle lever tightening devices secure one workpiece relative to a second work piece to locate the pieces for permanent connection. This toggle lever tightening device prevents deformation of the grip head and its seatings. The design of this toggle lever tightening device allows the grip head and cylinder to be constructed of light metal alloys without experiencing damaging deformation of the grip head. A very simple bearing arrangement for this toggle lever tightening device has made possible an embodiment in which a single tightening arm is provided on one side of the grip head. This single tightening arm design is highly desirable in the automobile industry. However, it results in an unfavorable introduction of forces. The pivot shaft that is driven by the toggle lever arrangement and functions to drive the tightening arm is axially and radially seated in the grip head.

Abstract: The invention is an improved jack having a safety device for preventing the jack from collapsing under a heavy load. The improved jack includes a linkage movable from a lowered position to an elevated position for engaging and elevating a load, an actuating mechanism connected to the linkage for moving the linkage toward the elevated position upon actuation of the actuating means, and the safety device blocking mechanism for blocking movement of the linkage from the elevated position to the lowered position. The linkage is supported and disposed for pivotal movement between two side plates. The blocking mechanism provides an abutment across the two side plates to limit the movement of linkage. The blocking mechanism features a block fixed to the linkage. The block has horizontal bores passing therethrough. A lock rod is inserted through the horizontal bores to provide an abutment across the two side plates when the linkage is elevated, thereby preventing the linkage from unintentionally lowering.

Vertical plates are initially formed as sidewall electrode depositions to pedestals formed on a substrate, and through a series of processing steps, additional vertical plates are formed so that multiple capacitor plate--dielectric--capacitor plate combinations are formed around each of the initial vertical plates. Exemplary embodiments and methods of fabrication are disclosed.

Abstract: A reluctance motor rotor is formed by sandwiching a stack of thin ferromagnetic laminations between two end caps. Each lamination has a series of slots formed in it, with the ferromagnetic material between these slots providing a flux guide. A rib is formed around the periphery of each lamination, thereby enclosing the slots. The slots are then filled with an epoxy resin through holes in the end cap. The resin, which is initially in the liquid state, is then cured in an oven. Once the resin is hard, the outer rib can be machined off to expose the resin. A rotor formed in this manner exhibits significantly higher output than prior art rotors of similar dimensions using magnetic bridges, and is relatively cheap to produce.
