摘要:
A semiconductor or dielectric wafer with conducting vias is used as a substrate in an integrated circuit packaging structure, where high density inter and intra chip contacts and wiring are positioned on the substrate face on which the integrated circuitry is mounted, and external signal and power circuitry is contacted through the opposite face. Use of a substrate such as silicon permits the use of conventional silicon processes available in the art for providing high wiring density together with matching of the thermal expansion coefficient of any silicon chips in the integrated circuits. The use of vias through the substrate allows a high density of connections leaving the silicon substrate and provides short paths for the connections of power and signals.

A Thermal Interface Material (“TIM”) composition of matter with improved heat conductivity comprises solderable heat-conducting particles in a bondable resin matrix and at least some of the solderable heat-conducting particles comprise a solder surface. Positioning the TIM between a first surface having a solder adhesion layer and a second surface, and then heating it results in soldering some of the solderable heat-conducting particles to one another; and some to the solder-adhesion layer on the first surface as well as adhesively bonding the resin matrix to the first surface and the second surface. The first surface can comprise an electronic device, e.g., a semiconductor device and the second surface a heat sink, such as a solderable heat sink. A product comprises an article of manufacture made by the process.

A probe or an electrical connector comprises a substrate with a surface having a plurality of electrical contact locations. A shaped elongated electrical conductor has a first end coupled to one of the electrical contact locations and a second end thereof which projects away from the electrical contact location and through an aperture in a sheet of material. The sheet is disposed to be spaced apart from the surface of the substrate. At the second end of the elongated electrical conductor there is a tip structure, which is larger than the aperture in the sheet of material. The tip structure has a pointed portion thereof. The tip structure is disposed against contact locations of a contact surface. The electronic structure is moved towards the contact surface permitting the tip structure to penetrate into the surface of the electrical contact location thereon and to move, wipe, or vibrate across the surface thereof as the shaped elongated electrical conductor flexes as a result of being compressed by the movement of the electronic structure toward the contact surface.

A hermetic pump includes a housing having a bore, an inlet, and an outlet for channeling a fluid therethrough. A shaft is disposed coaxially in the bore, and includes a journal and an impeller spaced apart therefrom. The shaft is hermetically rotated to pump the fluid through the bore from the impeller and around the journal for developing a hydrodynamic journal bearing. In one embodiment, the pump may be used in a closed loop cooling circuit.

摘要:
An arrangement and method for enhancing the cooling capacity of portable personal computers. The power dissipation of portable personal computers, especially such as laptop computers or the like, is enhanced through the utilization of a split swivable keyboard adapted to provide for an increased cooling surface area for electronic components generating heat during use of the computer.
摘要:
A method and structure is presented for a display with reduced size pixels while retaining the transmissive approach. This enables continued use the least expensive transmission optics available. In an embodiment, it employs back-end-of-the-line vertical cells built on top of the row and column x, y lines of the pixels. In a PDLC type display embodiment each vertical cell is filled with PDLC which operates in a normally black mode known as the PDLC reverse mode. When the pixel control voltage is set ON, the liquid crystal is perpendicular to the light path resulting in a light pass through providing a bright state. When the control voltage is set OFF, the liquid crystals are randomly oriented, only the scattered light goes through the cell, so the pixel is in its OFF state. PDLC used here has two advantages. Firstly, the PDLC requires no rubbing. It is difficult to rub individual cell walls. Secondly, the use of both polarizations by the PDLC increases its luminous efficiency. Various embodiments are described for implementing vertical active electrodes and common ground electrodes. Advantages are described for employing the vertical electrodes with various implementations of a hidden storage capacitor.
摘要:
The invention makes the size of the apparent image of the display screen of the display screen larger than the real size. A flat optical magnifier such as a lens of the fresnel type is positioned in an optically enhancing location between the operator and the display screen so that the apparent image at the operator side of the magnifier is greater than the actual image that is present on the display screen. A mechanism is provided for a notebook type portable computer that is passive to a user, folds into the case when the display screen closes over the keyboard and positions a fresnel lens, coplanar with and at a fixed distance from the display screen, when the notebook computer is opened and remains at that fixed distance as the display screen moves to maximum travel.
