Patent CA-2218307-C (CA)
Inventor: PATEL ATIN J
IPC: H01L25/00
Filed: 1997-10-10
Granted: 2006-01-03
Abstract: A multi-chip module (MCM) assembly has three stacked integrated circuit (IC) layers. The first IC layer is electrically flip-chip connected to a substrate. The back of the second IC layer may be glued to the back of the first IC layer, and the second and third IC layers are electrically flip-chip connected to each other. In one embodiment, the third IC layer is electrically connected to the substrate through a vertical interconnect element for high circuit density. In another, the second IC layer is electrically connected to the substrate using wire bonding for greater post-fabrication customization flexibility. In still another embodiment, the MCM assembly comprises two stacked IC layers where the second IC layer is electrically flip-chip connected to the first IC layer and the second layer is electrically connected to the substrate through a vertical interconnect element. By directly connecting IC layers, higher circuit density, lower trace impedance, and lower cross-talk or electrical noise susceptibility is achieved over that presently offered by most current MCM assemblies. The assembly accommodates different sized IC layers, multiple ICs on each layer, and different technology-based IC layers and ICs within each layer, providing the user with high design flexibility within a single multi-chip assembly.

Granted: 2001-10-02
Abstract: A roller with controllable sag is provided with a revolving hollow roller and a non-rotating crosshead which crosses the hollow roller along its length and on which the hollow roller is supported by a series of support elements actuated by a pressure medium. Separate supply lines (13) lead to the support elements and open out into a connection head (40) at the end (10') of the crosshead, to the connection head (40) are connected the outer connection lines (53). The connection head (40) comprises a double disc rotary slide valve (50) by which the lines (13, 53) can be interrupted and which in the closed state can be separated at a separation surface (47). The individual discs (51, 52) of the double disc rotary slide valve (50) keep both the supply lines (13) and connection lines (53) closed, thus facilitating replacement of the roller as and when required.

Granted: 2000-07-04
Abstract: A  voice  coil  actuator  includes  a  magnetic  flux conductive material core, a magnet and an electrical current conductive coil.  The core has a first surface and a continuous channel disposed in the first surface.  The channel has a pair of opposing walls.  The magnet is disposed in intimate contact with a first one of the walls and space from a second one of the walls so that a gap remains between the magnet and the second one of the walls.  The magnet has a first face of a first magnetic polarity facing the first one of the walls and a second face of a second, opposite magnetic polarity facing the gap.  The magnet is further spaced from a bottom of the channel so that magnetic flux is substantially normal from the second face across the gap to the second one of the walls.  The electrical current conductive coil is disposed moveably in the gap such that an electrical current in the coil develops a magnetic force on the coil in a direction substantially normal to the magnetic flux to displace the coil in response to the magnetic force.

Abstract: The present invention provides a paste for forming an internal electrode in a ceramic element. The paste causes no sudden heat generation from an organic vehicle contained therein during a degreasing step and allows Pd or Ag/Pd serving as an internal electrode to expand freely as a result of oxidation during a firing step, to thereby prevent structural defects of the ceramics such as delamination, when used for the formation of internal electrodes in a ceramic element such as a laminated ceramic capacitor. The paste contains a metal powder of Pd or Ag/Pd, Pd resinate, Cr resinate, and an organic vehicle. Preferably, the Pd resinate contains sulfur in the molecule. Also preferably, the paste contains the Pd resinate in an amount of 2.0-3.0 parts by weight as reduced to Pd, based on 100 parts by weight of Pd in the metal powder, and the Cr resinate in an amount of 0.03-0.12 parts by weight as reduced to Cr2O3, based on 100 parts by weight of the metal powder.

Abstract: An in-line agitating device for fluids includes an elongate internally-threaded cylindrical tube, open at each end, with a flow-disturber such as a round ball positioned inside the tube so as to substantially but not completely block off the bore of the tube. When a fluid is introduced into one end of the tube, its velocity increases as it is forced through the restricted space between the ball and the inner surface of the tube and then rapidly decelerates, causing turbulence which results in vigorous agitation of the fluid. This agitation is intensified by swirling action imparted to the fluid by the internal threading of the tube.

Abstract: An apparatus for securing a mandrel of a well tool in an operative position in which the mandrel is packed off against a fixed-point in the well is described. The apparatus includes a mechanical lockdown mechanism to secure the tool to the wellhead and maintain the mandrel in proximity to the fixed-point for packoff, and a mechanical or a hydraulic mechanism to move the mandrel into the operative position while the mechanical lockdown mechanism is in a lockdown position. A second mechanical locking mechanism is provided to ensure the mandrel is maintained in the operative position in the event that hydraulic pressure is lost. The invention provides a mechanism to lock down well tools requiring fixed-point packoff in a well and advantageously improves the range of adjustment of the lockdown mechanism so that the length of a mandrel may be less precisely matched to a distance from a top of the wellhead to the fixed-point in the well.

Abstract: A single centralized video controller is employed to convert and distribute video channels to one or more analog TVs (i.e., viewing devices or the like). This is realized without the need for changes to either the TVs or the interconnecting COAX. Specifically, the centralized controller includes one or more MPEG2 decoders, the number of which depends on a desired number of active TVs to be used in viewing different programs, and one or more wireless (e.g., radio frequency (RF)) communications links to television controllers (i.e., remote control units) associated on a one-to-one basis with the desired number of TVs. In operation, channel selection for each of the one or more TVs is communicated up-stream from the centralized controller to a remote video server and, therein, to a video services controller. The video services controller causes the video server to transmit only the selected program channels to the local centralized video controller. However, when the video channel is already being supplied from the video server to an optical line terminal and, specifically, to an optical line card to which the requesting centralized controller is connected to, there is no need to communicate the channel request to the video server. The optical line terminal simply supplies the requested channel via an optical line card to the additional requesting centralized controller and, in turn, to the requesting TV.
