Title: Improved low profile mounting of electronic components
Inventor: KAZLE SCOTT J
IPC: H01L21/60
Filed: 1997-05-01
Abstract: An improved circuit module construction for mounting and interconnecting electronic components to substrates, which is applicable to mounting a wide variety of electronic components and conductors, including inverted or 'flip chip' mounted integrated circuits. The components are mounted to the substrate with a sandwiched non-conductive polymer layer which acts as the bonding agent and underfill. The substrate and underfill have apertures aligned with signal traces on the substrate and the contacts of the component and conductive polymer is injected through the apertures to fill the area between the substrate contacts and the component contacts, to secure good electrical connection. In one embodiment the non-conductive polymer is printed on the contact side of the substrate with gaps for the contacts. In another embodiment B-staged non-conductive polymer is coated on the non-contact side of the substrate, prior to forming contact apertures and mounting of components. Conductive polymer is then injected in the apertures to make the electrical connections, and the assembly is cured. No coating or pre-treatment of the components is needed.

Patent CA-2212475-A1 (CA)
Inventor: PUGH JERRY THOMAS
IPC: B01L3/00
Filed: 1997-08-07
Abstract: A hollow, frustum-shaped disposable device is used in an apparatus for measuring the concentration of an analyte in a sample of a biological fluid. Thesmaller end of the frustum has a porous membrane, to which a sample of the fluid may be applied. Preferably, a reagent in the membrane reacts with the analyte to cause a color change. The device is mounted on a meter, which measures the color change and computes from the change the analyte concentration in the sample. The apparatus permits remote dosing of the device, which minimizes the likelihood of cross-contamination between the user and the meter. Devices can be mounted on the meter and released from the meter without touching them, to further protect against contamination.

Patent CA-2228464-A1 (CA)
Title: Device and method for molding motor coils
Inventor: KANAI YASUHIRO
IPC: H02K15/12
Filed: 1998-02-02
Abstract: In molding coils wound around a motor rotor with resin material in a die assembly, the coil ends projecting from either axial end of the motor core are compressed radially inward by small diameter portions formed in the die surface. Because the unnecessary deposition of the resin material over the coil ends is minimized, the material cost can be reduced. Also, the elimination or the reduction of the need to eliminate excess resin material from the coil ends simplifies the production process, and reduces the production cost. Additionally, the reduction in the mass of the resin material over the coil ends, as well as the constraining of the coil wire into a relatively radially inner parts reduces the moment of inertia of the motor rotor, and can thereby improve the performance of the motor.

IPC: G01N27/407
Filed: 1998-08-06
Abstract: An oxygen sensor is disposed downstream from a catalyst for purifying exhaust gas from an internal combustion engine and which can suppress an influence of unburnt hydrocarbon on an output voltage. After forming a platinum thin film on the outer periphery of a zirconia ceramic body, only a detection electrode of the ceramic body is dipped in a silver nitrate aqueous solution of 0.1 mol/l, and the silver nitrate is pyrolyzed through a heat treatment. Subsequently, a platinum reference electrode is formed on the inner periphery of the ceramic body. To protect the silver-doped detection electrode, a protective layer is formed on the surface of the detection electrode. By the exposure to combustion gas and through aging, a detection element is formed, and set into a metal case together with a cylindrical heater, to complete an oxygen sensor to be disposed downstream from a CNG engine catalyst.

Abstract: In a video noise reducer, the problem of noise at the edges of moving objects is dealt with by the introduction - into those regions - of spatial noise reduction. An adaptive low pass filter works especially well for spatial noise reduction, with adaption by reference to a dynamic noise measurement. Also, where pixel information is recursively filtered, with recursion being disabled at a disjuncture (caused by motion, panning, shot-change or otherwise), recursively filtered pixel information prior to a disjuncture continues to be output until pixel information following the disjuncture has been recursively filtered to an appropriate degree of noise reduction.
