Abstract: A collet and lock nut assembly includes a collet for receiving a cutting tool shank and a lock nut for creating a gripping force between the collet and the shank. The collet has a nose portion and a body portion separated by an annular groove. The lock nut has a plurality of retention tabs and a corresponding number of clear portions. The collet and lock nut assembly can be easily assembled by inserting at least one retention tab within the groove of the collet, and then applying pressure to the collet such that the remaining retention tabs of the lock nut are received within the groove of the collet to place the assembly in a locked position. The collet and cutting tool shank can be drawn from the tool holder by applying rotational torque to the lock nut. The collet is easily removed from the lock nut by applying pressure in any circumferential, lateral direction against the collet.

Abstract: An apparatus is disclosed for releasably holding a toolholder shank having a lockable surface and a releasable surface utilizing an actuating bolt with an associated threaded actuating nut. When the actuating bolt is rotated in a locking direction, the actuating nut is drawn onto the bolt thereby clamping against the lockable surfaces of the toolholder shank. When the actuating bolt is rotated in the releasing direction, a releasing segment acts upon the toolholder thereby ejecting it from the tool support member.

Abstract: A FinFET body contact structure and a method for creating the FinFET body contact structure are disclosed. The body contact structure comprises a wide fin portion of a semiconductor fin, the wide fin portion having a polysilicon polygon shape formed on a top surface of the wide fin portion. The polysilicon polygon shape has a center area having no polysilicon. FinFETs are formed on two vertical surfaces of the wide fin portion and gates of the FinFETs are coupled to the polysilicon polygon shape. Top surfaces of the wide fin portion and the polysilicon polygon shape are silicided. Silicide bridging is prevented by sidewall spacers. All convex angles on the polysilicon polygon shape are obtuse enough to prevent creation of bridging vertices. The center area is doped of an opposite type from a source and a drain of an associated FinFET.

Abstract: A rotary tapered tool holder includes a shank including a front mounting portion and an aperture. An expansion sleeve is disposed about a portion of the shank. The expansion sleeve includes a front mounting portion adjacent the front mounting portion of the shank. An expansion rod is disposed within the shank and includes a pocket or cam surface. An expansion pin is at least partially received in the aperture of the shank. The expansion pin has a first end or cam surface for engaging the pocket of the expansion rod, and a second end for engaging the front mounting portion of the expansion sleeve. A force applied to the expansion rod in a first direction causes the expansion pin to move in a second direction and into positive engagement with the front mounting portion of the expansion sleeve, thereby forcing the expansion sleeve into positive contact with a tapered bore of a spindle of the tool holder.

Abstract: A single compression engine determines a plurality of discrete cosine transform (DCT) coefficients based on a discrete cosine transform of a plurality of blocks of data. The single compression engine provides first and second DCT-encoded signals. The first DCT-encoded signal uses at most t coefficient bits to represent each of the DCT coefficients. The second DCT-encoded signal uses at most u coefficient bits, where u is less than t, to represent each of the DCT coefficients.

Abstract: A rotary tapered tool holder includes a body or shank including a front contact portion and a rear contact portion. An adapter sleeve is disposed about a portion of the shank. The adapter sleeve includes slits that allow radial expansion and contraction of the adapter sleeve. The adapter sleeve includes an inner surface formed at a first non-zero taper angle with respect to a longitudinal axis of the shank, and an outer surface formed at a second non-zero taper angle with respect to the longitudinal axis of the shank. The second taper angle is different than the first taper angle such that an interference fit between the shank and the inner surface of the adapter sleeve forces the outer surface of the adapter sleeve into positive contact with a tapered bore of a spindle of the rotary tapered tool holder.

Abstract: An apparatus for measuring alignment of polysilicon shapes to a silicon area. Each polysilicon shape in a first plurality of polysilicon shapes has a bridging vertex positioned near the silicon area. Each polysilicon shape in a second plurality of polysilicon shapes has a bridging vertex positioned near the silicon area. The second plurality of silicon shapes is positioned on the opposite side of the silicon area from the first plurality of silicon shapes. An electrical measurement of how many of the polysilicon shapes in the first plurality of polysilicon shapes and in the second plurality of polysilicon shapes provides a measurement of alignment of the polysilicon shapes and the silicon area.

Abstract: A cutting tool for use on earth working and land clearing equipment includes a working body portion having a cavity disposed therein which begins at a peripheral edge of a first end and extends inwardly towards a second end of such working body portion. The cavity is provided with a cutting portion disposed at an acute angle about such peripheral edge. A mounting shank extends outwardly from and is attached to the second end of the working body portion for enabling attachment of the cutting tool to a tool holder used on such earth working and land clearing equipment. At least one pin member engaging the complimentarily aligned grooves within an aperture of the tool holder and an outer surface of the shank portion is used to securely retain the cutting tool within the tool holder.

Abstract: A clamp pin tool holder for clamping an insert in a tool holder includes a bore for receiving a clamp pin and a bore for receiving a lock screw. The clamp pin includes a cam portion with angled surfaces. The lock screw is rotatably mounted to the bore of the tool holder and includes angled surfaces for engaging the angled surfaces of the clamp pin. When the lock screw is rotated in one direction, one angled surface on the lock screw and one angled surface on the clamp pin engage each other an acts as a conical wedge to cause the clamp pin to move relative to the lock screw. When the lock screw is rotated in the opposite direction, another angled surface on the lock screw engages a different angled surface on the clamp pin in a similar manner to cause the clamp pin to move in an opposite direction.

Abstract: An improved retaining system for securing a cutting tool to a support block rigidly attached to an outer surface of a carrier. The retaining system includes a first groove formed in an outer surface of a shank portion of the cutting tool in a direction transverse to a longitudinal axis of the shank portion. There is a second groove formed in a surface of a bore formed through an axis of the support block for receiving the shank portion of the cutting tool and formed generally perpendicular to a rotational axis of such carrier. The first groove is radially opposed to the a second groove when the shank portion is inserted into the bore of the support block. The final essential element of the retaining system is a pin member engageable with each of the first groove and the second groove for securing the cutting tool to the support block.

Abstract: A rotary tool holder includes a shank having a flange, a tapered outer surface, and front and rear contact portions. The tapered outer surface corresponds to the tapered bore of a spindle, and flexible circular cantilevers are provided at one or both contact portions such that a free end of the cantilevers expands radially due to centrifugal force to maintain contact with the tapered bore. The shank can be formed from an inner member and a sleeve disposed thereover, in which portions of the sleeve form the circular cantilevers. The circular cantilevers can also be formed by a cavity created in the shank. Alternatively, instead of circular cantilevers, the shank of the tool holder can have a taper which is optimized for a certain speed, wherein the taper of the shank has a first taper at rest and a different, optimized taper at a desired speed.

Abstract: An assembly generally comprises a collet for receiving a cutting tool shank and a lock nut for creating a gripping force between the collet and the cutting tool shank. The collet has a nose and the lock nut has a front face that is substantially flush with the nose. The lock nut further has a fastening element that mates with a fastening element of a coolant sealing ring for attaching the coolant sealing ring to the lock nut so that the coolant sealing ring may be detached from the lock nut.

Abstract: A zero centerline toolholder assembly includes a cutting insert mounted to a toolholder. The center, RC, of the nose radius of the cutting insert is aligned with or lies on a centerline, LT, of the toolholder. The centerline, LT, of the toolholder may be also aligned with a rotational axis, CT2, of a tool spindle. The tool spindle is tilted at an angle with respect to an axis, P, that is substantially perpendicular to a longitudinal axis, LW, of a work piece. As a result of the zero centerline configuration, the radial component of the torque load on the toolholder is virtually eliminated. In addition, the toolholder assembly has a shorter tool length, thereby reducing deflection load on the toolholder.

Abstract: A method for making a magnetic disk, without chemical mechanical polishing to remove asperities, includes the steps of placing an annular-shaped element in a vacuum chamber, exposing a surface of the element to a beam of gas clusters while it is in the vacuum chamber, and thereafter applying a magnetic coating. The annular-shaped element may be a substrate, or it may be a substrate with a base coating such as glassy carbon or amorphous carbon. The substrate may be made of glass, preferably high quality fusion glass. The surface of the annular element may be textured by forming a sequence of concentric annular valleys, with plateaus being left between the valleys, before the magnetic coating is applied. A semiconductor wafer may also be smoothed by a beam of gas clusters to prepare the wafer for photolithography.

Abstract: A method comprises determining a plurality of time intervals Tp and Tn within a variable bit rate (VBR) representation of an image sequence. The time intervals Tp are those in which a number of blocks of information per unit time is greater than a baseline value. The time intervals Tn are those in which a number of blocks of information per unit time is less than the baseline value. A second representation of the image sequence is created in which some blocks of information Bp are removed from the time intervals Tp and interlaced with blocks of information Bn in the time intervals Tn to reduce a variation in a number of blocks of information per unit time between the time intervals Tp and Tn.
