Patent CA-2116766-A1 (CA)
Title: Solder Bump Fabrication Method and Solder Bumps Formed Thereby
Inventor: YUNG EDWARD K
IPC: H01L21/60
Filed: 1992-09-11
Abstract: The base of solder bumps is preserved by converting the under-bump metallurgy between the solder bump and contact pad into an intermetallic of the solder and the solderable component of the under-bump metallurgy prior to etching the under-bump metallurgy. The intermetallic is resistant to etchants which are used to etch the under-bump metallurgy between the contact pads. Accordingly, minimal undercutting of the solder bumps is produced, and the base size is preserved. The solder may be plated on the under-bump metallurgy over the contact pad through a patterned solder dam layer having a solder accumulation region thereon. The solder dam is preferably a thin film layer which may be accurately aligned to the underlying contact pad to confine the wetting of the molten solder during reflow. Misalignment between the solder bump and contact pad is thereby reduced. The solder bumps so formed include an intermetallic layer which extends beyond the bump to form a lip around the base of the bump. This lip provides extra protection for the solder bump.

Title: Air, propane and oxygen burner with no exit flame
Inventor: SESTRAP ARV M
IPC: F23D14/52
Filed: 1994-10-11
Abstract: A hot air Burner in which a nozzle assembly is com-prised of an inlet port housing (8) incorporating an internal plenum chamber (18) into which is introduced a flow of compressed air via an inlet port (4) in the inlet housing (8). The flow of compressed air is controlled by the width of an adjustable gap created be-tween a frusto-conical exterior surface (20) of the internal plenum chamber (18) and the internally chamfered wall (22) of a mixing tube (12). Turbulence in the compressed air flow is created as the air enters the mixing tube (12) and this swirling effect promotes efficient mixing of subsequently introduced combustible gases to the mixing tube (12) via an inlet port (6) in the inlet housing (8). The combustible mixture is ignited and the result-ant combustion contained within the confines of an outer burner tube (10). The flame front is contained within the burner tube (10) and extends approximately six inches into the length of the tube (10). The high temperature exhaust gases are carried to the exit opening of the burner tube (10) by the continuous flow of compressed air and thus avail-able, flame free, for application.

Filed: 1995-03-28
Abstract: Methods for detecting, immobilizing or localizing primer extension products of aStrand Displacement Amplification reaction which are coupled to, and an indication of, amplification of the target sequence. The primer extension products are secondary, target-specific DNA products generated concurrently with SDA of the target sequence and can therefore be used to detect and/or measure target sequence amplification in real-time. In general, the secondary amplification products are not amplifiable and remain inert in the SDA reaction after they are formed without interfering with amplification of the target sequence. The secondary amplification products may be designed or modified to contain special features to facilitate their detection, immobilization or localization.

Abstract: A method of testing the accuracy of results obtained from an automatic viscometer is described.   Firstly, provide an automatic viscometer having at least two capillary tube test sections,  each of a distinct uniform diameter.   Secondly, calibrate the automatic viscometer by allowing a Newtonian fluid of known viscosity to flow through each of the capillary tube test sections and recording the time duration of the flow of the Newtonian fluid through each of the capillary tube test sections.  Thirdly, calculate a viscosity constant for each capillary tube test section by dividing the known viscosity by the recorded flow time.  Fourthly, send a test sample through each of the capillary tube test sections and record the time duration of the flow of the test sample through each of the capillary tube test sections.  Fifthly, calculate values for the viscosity of the test sample based upon the times recorded and the known viscosity constant for each of the at least two capillary tube test sections.  Sixthly, compare the viscosity measurement derived from each of at least two capillary tube test sections. A difference in viscosity measurement exceeding a predetermined limit  indicating that the measurement  is suspect and the accuracy of the automatic viscometer must be checked  as  the  test  sample  is  exhibiting  non-newtonian behaviour.

IPC: H02J7/14
Filed: 1995-07-13
Abstract: A high output  alternator and regulator  for generating electrical power in a motor vehicle having a storage battery for providing  stand-by  power at a predetermined voltage.   The alternator is a mechanically driven generator having stator windings across which a three-phase AC voltage is produced at an amplitude determined by the amount of current fed through a field winding.  A first rectifier is for rectifying the three-phase AC voltage to provide a DC battery voltage to supply other DC voltage loads and a second rectifier rectifies the three-phase AC voltage and inputs into a voltage multiplier circuit which amplifies the rectified voltage.  The voltage multiplier circuit inputs the amplified voltage into a voltage regulator having inputs which sense the battery voltage. The voltage regulator outputs the voltage at full or a fractional magnitude of the multiplied DC voltage to control the field current fed through the field winding of the generator to cause a three-phase AC voltage developed across stator windings of the generator to have an amplitude necessary to establish and maintain the DC battery voltage at its predetermined magnitude.
