摘要： A linear chemical mechanical planarization (CMP) system includes a belt pad, a slurry bar having a plurality of nozzles, and a heating module for heating slurry. The heating module has a plurality of heating elements, each of which is coupled in flow communication with one of the plurality of nozzles of the slurry bar. The system also may include a control system for controlling the heating elements of the heating module and first and second temperature sensors coupled to the control system. The first temperature sensors measure the temperature of slurry heated by each of the heating elements, and the second temperature sensors measure the temperature of the surface of the belt pad. A method for dispensing slurry in a linear CMP system, and methods for controlling the temperature of the surface of the belt pad and the temperature of slurry in a linear CMP system also are described.

摘要： An apparatus and method for evenly distributing a polishing fluid onto a polishing pad during a chemical mechanical planarization process, wherein the polishing fluid is dispersed by way of a spray being emitted from a spray nozzle. The pattern of polishing fluid applied to the polishing pad can be modified by adjustment of geometric parameters of the spray nozzle. The apparatus is configured with actuating mechanisms for translating and rotating the spray nozzle relative to the polishing pad in order to adjust a pattern of distribution of the polishing fluid. The method of dispersing polishing fluid onto the polishing pad produces an even distribution of polishing fluid across a width of the polishing pad.

摘要： A reproduction machine incorporating self test routines to test the machine operating logic, particularly at start up, to insure the integrity and operability of the component parts of the operating logic. The tests include routines for initially checking the machine master control module logic and memory. A display panel on the master control module visually identifies any fault in the event the communication link to the machine main display has failed. Once the operability of the master control module is established, self tests of the various machine remote control modules are carried out followed by a test of the communication channel between all modules. Any fault found is visually identified to facilitate repair and servicing.

摘要： A nipple for a baby bottle includes both inner and outer separable members. The inner member defines a valve passage that can be selectively obstructed by a flap of the outer member. The outer and inner members have respective flexible membranes that define a holding chamber having the valve passage as an inlet and an aperture at the tip of the outer member as an outlet. The flap inhibits flow from the holding chamber through the valve passage when the outer member is compressed, and deflects away from the valve passage to allow the holding chamber to receive a fluid through the valve passage when the outer member is released.

摘要： An annular groove of a can end with a reduced radius is disclosed. In one embodiment, this is by a method and apparatus which reworks the can end to increase the strength of the can end by reducing the radius of the annular groove of the can end. This method includes the step of reworking the annular groove of the can end to reduce a magnitude of the annular groove from a first radius to a second radius by exerting an inwardly-directed force on at least part of the annular groove and relative to the annular groove and collapsing at least part of the annular groove inwardly relative to the annular groove. The apparatus used in this reworking may include inner and outer die surfaces, wherein at least one of which engages a lower portion of the annular groove, and a punch, opposing and axially movable relative to the annular groove and die surfaces, for engaging the annular groove to exert inwardly-directed forces on the lower portions of the annular groove to collapse the lower portions of the annular groove inwardly, toward the punch. The reduced radius may also be achieved in a blank and form station where an axially-directed force is exerted on a flange such that portions of the blank flex into engagement with a generally concave die surface.

摘要： An intraocular lens includes an optic for implantation in a human eye and first and second fixation members attached to the optic for supporting the optic from the capsular bag of the eye, each of the fixation members having inner and outer legs. The inner legs extend radially outwardly and circumferentially from first and second attachment sites on the optic to intermediate portions of the fixation members. Each of the outer legs extend along an arc from the intermediate portion of the fixation member to a distal end portion of the fixation member. The arcs extend along a circle that is centered on an optical axis of the optic, the circle has a diameter that is approximately equal to the diameter of the capsular bag, and each of the first and second outer legs has a length such that the distal end portion of each of the fixation members is disposed proximate the intermediate portion of the other fixation member so that the first and second fixation members can abut a substantial portion of the capsular equator of the capsular bag and yet flex radially inwardly slightly to accommodate variations in the diameter of the capsular equator.

摘要： The present invention relates to improvements in the strength of ends used on metal beverage containers. Such ends generally comprise a central panel portion of a substantially planer character, a surrounding U-shaped sidewall having inner and outer legs, a curved intermediate portion integrally joining the inner leg to the U-shaped sidewall, and a peripheral curl extending from the outer leg for double seaming the end onto a can body. In accordance with the present invention, the intermediate portion and adjacent central panel portion are firmly supported by a die while a clamping force is placed on an annular band of the upper surface of the end at the intermediate portion. The clamping force is increased until metal flows inwardly and outwardly from the contact point resulting in a free compression doming of the center panel and an outward deflection of the inner leg. An end of increased buckle resistance is thereby produced which end is approximately within standard dimensions such that customers can use the end on existing seaming equipment without alteration. An optional feature is provided to minimize the compression doming by clamping a peripheral band of the end with a hold-down pad while the metal flowing is accomplished. This reduces the dome depth and results in a strengthened end having a dome depth very close to standard specifications.

摘要： Energy absorbing structure disposed beneath the cargo area of an aircraft provides maximum energy absorption and structural strength using carbon fiber reinforced epoxy composites. The energy absorbing structure uses laminated stanchions having ply drop-offs to produce stable, progressive crushing of the stanchions during a wheels-up crash landing. Integrally formed flanges on the stanchions allow direct mounting of the stanchions on the structural members of the aircraft, without the need for specialized fittings.
