Patent CA-2101881-A1 (CA)
Inventor: MAYERNIK RICHARD A
IPC: C23C18/40
Filed: 1993-08-04
Abstract: ABSTRACT        An improved method of manufacturing fully-additive or partly-additive printed wiring boards by electrolessly depositing copper on an insulating substratum and the walls of plated-through holes, wherein the copper deposit has increased resistance to failure due to thermal stress or thermal cycling. The electroless copper plating bath contains a copper compound, ethylenediaminetetraacetic acid as a complexing agent for copper, a reducing agent capable of reducing the copper compound to metallic copper and addition agents selected from inorganic germanium and silicate compounds and combined with a polyethylene glycol. The pH of the electroless copper bath is monitored and maintained between  11.2 and 12.0 to reduce the trace iron codeposited with the copper and improve the resistance to plated-through hole failure in thermal cycling. The addition of vanadium to the electroless copper bath increases the smoothness of the deposited copper and further increases the number of thermal cycles before failure.

Title: Method and apparatus for treating diesel exhaust gas to remove fine particulate matter
Inventor: MILLER JOHN W
IPC: F01N13/04
Filed: 1992-02-24
Abstract: An emissions control system for reducing particulates from exhaust gases from a diesel engine includes dual catalyzed diesel particulate filters in joint communication with the exhaust stream and a pair of heater elements each associated with one of the filters, through which exhaust gas is transmitted and uniformly heated. According to predetermined alternating heating sequence, the exhaust gas stream through first one of the pair of filters and then through the other is heated. The differing pressure differentials across the filters, determined by the heating sequence, effectively shift the major portion of the flow of exhaust gas between the filters, so that over the alternating heating sequence the heat generated by the heating elements is sufficient to clean the filters, without the requirement for any auxiliary source of combustion air or any mechanical switching means.
Patent CA-2106140-A1 (CA)
Inventor: MINAMI YOICHIRO
IPC: H04L27/14
Filed: 1993-09-14
Abstract: In an FSK receiver of double superheterodyne type for receiving an FSK modulated wave and comprising a PLL local oscillator (10) for ensuring a phase-locked loop to produce a first local oscillation signal and a demodulating section (12) for demodulating the FSK modulated wave into a demodulated signal using the first local oscillation signal and a second local oscillation signal, a control signal producing circuit (14) produces a control signal when the demodulated signal has a mean value indicative of a deviation from a phase lock in the phase-locked loop.  Connected to the demodulating section, a synchronizing circuit (16) establishes bit and frame synchronization on the basis of a binary digital signal obtained by deciding the demodulated signal to produce a synchronization detection signal when the bit and frame synchronization is established.  Connected to the PLL local oscillator, the control signal producing circuit, and the synchronizing circuit, an intermittent driving circuit (18) makes the PLL local oscillator intermittently operate on the basis of the control signal and the synchronization detection signal.  The PLL intermittent driving circuit makes the PLL local oscillator stop its PLL operation when the control signal is absent while the PLL intermittent driving circuit makes the PLL local oscillator activate the PLL operation when the control signal is present.

Abstract: An improved method and apparatus for discriminating between currency bills (17) of different denominations uses an optical sensing (18) and correlation technique based on the sensing of bill reflectance characteristics obtained by illuminating (22) and scanning a bill along its narrow dimension.  A series of detected reflectance signals are obtained by sampling and digitally processing (30), under microprocessor control, the reflected light at a plurality of predefined sample points as a currency bill is moved across an illuminated strip (24) with its  narrow dimension parallel to the direction of transport of the bill.  The sample data is subjected to digital processing, including a normalizing process, whereby the reflectance data represents a characteristic pattern that is unique for a given bill denomination and incorporates sufficient distinguishing features between characteristic patterns for discriminating between different currency denominations.
