Abstract:
The present invention provides an electrically conductive adhesive composition having cured low modulus elastomer and metallurgically-bonded micron-sized metal particles and nano-sized metal particles. The low modulus elastomer provides the mechanical robustness and reliability by relieving the stresses generated; and the metallurgically-bonded micron-sized metal particles and nano-sized metal particles provide a continuous conducting path with minimized interface resistance. Addition of nano-sized metal particles lowers the fusion temperature and allows the metallurgical-bonding to occur at manageable temperatures.
Abstract:
A curable composition is provided, and a method associated therewith. The curable composition may include a curable resin and a finely divided refractory solid. The solid may have a surface area that is greater than about 5 square meters per gram, and a determined density of active surface termination sites per square nanometer of surface area.
Abstract:
Email messages are stored without organization; the email messages are not stored in folders, and are otherwise not organized for storage purposes. The messages each have attributes, such as the folder in which they are to be displayed. The messages are organized, such as in folders, just for display purposes—the messages themselves are not moved; only attributes of the messages change. The messages are indexed by their contents. Metadata regarding the messages are stored as partially ordered logs of updates to the messages' attributes. The metadata may be stored as metadata events, where an event describes a change to an attribute of a message. A log of the events is partially ordered in that the events are organized in the order in which they occur as to a specific copy of the messages, but not necessarily in the order in which they occur as to all copies.
Abstract:
A tube holder for use with a peristaltic pump includes a housing having a recess for receipt of a pump rotor and a tube race around the recess. The tube race has a first race part and a second race part, a first tube inlet into the first race part and a first tube outlet from the first race part, a second tube inlet into the second race part and a second tube outlet from the second race part. The tube is insertable in the tube race by movement in a substantially orthogonal direction relative to the tube race so that it extends in through the first tube inlet, around the first race part, out through the first tube outlet, in through the second tube inlet, around the second race part, and out through the second tube outlet.

Abstract:
A decoupling device (10) includes a plurality of capacitors having different capacitances (14,16,18) physically mounted in a package (12, 212), and terminals including at least one first terminal (24, 224) and at least one second terminal (26, 226) adapted for mounting the package to a circuit panel. The plural capacitors are connected in parallel between the first and second terminals so as to form plural circuits with different self-resonant frequencies. The device can be mounted as a unit on a circuit board with the first terminals connected to a power conductor and the second terminals connected to a ground conductor, and provides low impedance shunting of noise over a wide frequency spectrum.
Abstract:
An integrated circuit memory device includes a memory, a read control circuit operatively associated with the memory and configured to produce data from the memory responsive to an externally-applied input clock signal, and an output latch configured to transfer data at an input thereof to an output pad of the memory device responsive to an externally-applied output clock signal. The device further includes a clock domain alignment circuit configured to receive the data produced by the memory and to responsively provide the data at the input of the output latch based on relative timing of the input clock signal and the output clock signal.
Abstract:
A microelectronic assembly incorporates units stacked one above the other and may include a plurality of similar stacks mounted to a circuit board. Some of the stacks may be inverted, rotated or both relative to other stacks so that corresponding edges of the stacks face one another to facilitate communication between the stacks. Communication between the stacks may be carried along traces on one or more interposers intercepting the stacks remote from the circuit board. Within each stack, conducting paths may extend in vertical columns or in other arrangements such as a stair step arrangement wherein each conductive path traverses a series of column positions, or in a crossing arrangement such two conductive paths cross back and forth between column positions along the vertical extend of the stack. A stack may include portions disposed above and below the circuit board.

A solvent-modified resin composition for use as underfill material is provided. The composition having at least one epoxy resin, at least one solvent and a filler of functionalized colloidal silica. The solvent-modified resin composition is useful in making transparent B-stage resin films. Embodiments of the disclosure include use as a wafer level underfill, and an encapsulant for electronic chips.
Abstract:
An apparatus addresses ink jet heating elements based on image data to cause ejection of ink droplets toward a print medium. The apparatus includes a controller for generating address signals, power signals, and first and second bank signals. The first and second bank signals, which are carried on first and second bank lines, alternate between on and off states. The first bank signal is off when the second bank signal is on, and the second bank signal is off when the first bank signal is on. The apparatus has m address lines and n power lines connected to the controller for carrying the address signals and the power signals. A print head has m×n number of first driver circuits, each of which is connected to the first bank line and to a corresponding one of the m address lines. The first driver circuits enable flow of a first driving current when the first bank signal and the address signal are simultaneously on on the first bank line and the corresponding address line. The print head has m×n number of second driver circuits, each of which is connected to the second bank line and to a corresponding one of the m address lines. The second driver circuits enable flow of a second driving current when the second bank signal and the address signal are simultaneously on on the second bank line and the corresponding address line. First heating elements are each connected to a corresponding one of the first driver circuits and to one of the n power lines. A first heating element is activated by the first driving current when the power signal is on on the connected power line and the corresponding first driver circuit enables flow of the first driving current. Second heating elements are each connected to a corresponding one of the second driver circuits and to one of the n power lines. A second heating element is activated by the second driving current when the power signal is on on the connected power line and the corresponding second driver circuit enables flow of the second driving current.
