Title: Wiring substrate and production method thereof
Inventor: SUZUKI TAKESHI
IPC: H05K3/20
Filed: 2000-11-23
Granted: 2002-08-11
Abstract: The present invention aims to provide a wiring substrate highly reliable in insulation and connection and a method for manufacturing the wiring substrate. The wiring substrate comprises two or more wiring layers, insulation layers interposed between the neighboring wiring layers and containing an organic resin, and via formed in the insulation layers and extended between neighboring wiring layers. The via contain functional substances, as well as some of the voids (first voids) where at least the organic resins from the insulation layers exist and the remaining voids (second voids) where a gas exists. Consequently, so-called paste bleed, which is penetration of an insulation layer with a conductive paste, does not takes place and the elasticity modulus in the entire via becomes low and the flexibility is improved attributed to the second voids in the via. The expansion and the contraction well respond to the mechanical stress applied to the wiring substrate and thus disconnected of wiring layers hardly takes place and the reliability of electric and mechanical connection between the wiring layers is improved.

Title: Thermal barrier and reactor coolant PUMP incorporating the same
Inventor: VERONESI LUCIANO
IPC: F04D29/10
Filed: 2001-02-20
Granted: 2002-11-11
Abstract: A thermal barrier for a nuclear reactor coolant pump includes a stack of pancake cooling coils encircling the pump shaft where it enters the pump chamber. This stack of coiling coils has an irregular peripheral surface formed by axially extending, diametrically opposed, inlet and outlet tubes which are circumferentially indexed for each pancake coil. The inner surface of a cylindrical cover has a complimentary inner peripheral surface formed by two sets of diametrically opposed cascaded steps so that the volume of the annulus between the coil stack and cover is minimized to reduce stratification of cooling water injected into the cover. A collar around the pump shaft at the opening in the end wall of the cover extends axially into the coil stack to prevent vortices produced by the spinning shaft from flowing across the end wall of the cover, while circumferentially spaced holes in the collar prevent significant alteration of the thermal conditions of the pancake coiling coils. An integral flange on the collar serves as a shim for the stack of coils. An external insulator includes a sleeve with a low coefficient of thermal expansion shrink fit over a groove in the outer surface of the cylindrical cover to form an annular chamber which is divided by a number of nested cans into a plurality of concentric sections each containing stagnant reactor coolant.

Title: Digital pen using interferometry for relative and absolute pen position
Inventor: SMITH BARTON ALLEN
IPC: G06F3/041
Filed: 2001-08-20
Granted: 2004-10-11
Abstract: A digital pen that has an ink writing tip includes a laser on a pen body that directs light toward paper across which the writing tip is stroked. A diffraction grating reflects a reference beam and passes a scattered beam from the substrate toward translation detectors, which consequently receive interference patterns of light. A processor receives the signals from the detectors, generates position signals, and stores the signals. Also, a bar code detector receives a bar code beam from the substrate, and a three dimensional force sensor outputs a signal representative of multidimensional forces applied to the pen. Subsequently, the signals are uploaded to a host processor which combines them to produce rotation-corrected relative positions (if no bar coded paper is used) or rotation-corrected absolute positions (if bar coded paper is used) that can be used to render alpha-numeric characters or graphical representations.
