Patent EP-0730395-A2 (EP)
Inventor: TENCH D MORGAN
IPC: H05K3/00
Filed: 1996-01-18
Abstract: A method is provided for dynamically transporting and applying a liquid to a surface, such as the bottom surface of a printed wiring assembly (PWA). The liquid may comprise an aqueous reducing agent solution for removing surface oxides prior to a soldering operation. The PWA is placed in proximity with the treatment solution held in a reservoir. Gas bubbles generated in the solution dynamically elevate and apply the solution to the bottom surface of the PWA. The bubbles may be formed by a non-oxidizing gas, such as nitrogen, introduced through a porous material. A flat surface of porous material produces a uniform bubble size that allows controlled and precise application of the solution. The porous material and the gas pressure may be varied to so that the bubbles elevate the solution to the desired level. The gas bubbles are short-lived (without surfactants) so that rapid transport, replenishment, and regeneration of the solution can be achieved. Moreover, nitrogen gas is injected at the PWA surface as the bubbles burst so that reaction of the solution or the PWA with oxygen is minimized. The gas bubble method also minimizes the pressure that forces treatment liquid through PWA through-holes to the top surface where it can be difficult to remove.

Abstract: In a molded surface fastener manufacturing method, molten resin (4) is injected or extruded from an injection die (1) or an extrusion nozzle (11), and at the same time, a coarse mesh core sheet (S) is introduced between the extruded molten resin (4) and the circumferential surface of a die wheel (2), which has a multiplicity of hook-element-forming circumferential cavities (5). The core sheet (S) is forced against the circumferential surface of the die wheel (2) by a pressing force of a press roller (13) or under a molten resin pressure at the time of injection or pass part of the molten resin (4) through pores of the core sheet (S) and to fill in the hook-element-forming cavities (5). As a result, a multiplicity of hook elements (4b) are molded, and at the same time, the core sheet (S) is embedded integrally in a plate-like substrate sheet (4a) eccentrically to the hook-element-surface side.

Abstract: A video source (101), such as a VCR, plays back a motion image which is input by an image input section (111). 
     Partition of scenes and creation of images representing scenes are performed by a catalog creation section (120).

Abstract: The invention relates to a fixed gap waveguide taper. The waveguide taper has a first end and a second end for being coupled to a fiber. The waveguide taper includes a plurality of segments (108) extending from the first end toward the second end. The segments include a gap portion (5) and a core portion (t). In the present invention, the gap portion remains fixed at a constant length  s  throughout the entire waveguide taper. In contrast, the core section length of the segment varies from the waveguide end of the taper toward the fiber end of the taper. In particular, the core section in each of the segments progressively decreases in length from the waveguide end toward the fiber end of the taper. Accordingly, the length of the segment Λ progressively decreases from the waveguide end toward the fiber end of the taper.

Abstract: A method for infrared (IR) imaging using a panel made of integrated GaAs quantum well
infrared photodetector (QWIP) and near-infrared (NIR) or visible light emitting diode (LED).
The panel is a large area diode with an optical window for top illumination or without the
window for backside illumination. The integrated device acts as a photon energy up-converter
which converts infrared light of wavelength longer than about 1.1 µm to near infrared or visible
light which falls into the silicon detector spectral range. Using this device, an IR image is up-converted
and the resulting NIR or visible image is then detected by an off-the-shelf silicon
charge-coupled-device (CCD) camera. The image detected on the CCD camera represents the
original infrared image. A specific device embodiment for converting 9 µm IR to 870 nm NIR is
given. Using this up-conversion scheme a multicolor or multispectral version is easily realized,
which provides the capability of simultaneously imaging in several infrared wavelength regions.
The imaging panel can also be used with other forms of photodetectors.

Abstract: A test system for testing the quality of electric appliances includes a test line
having an endless conveyer which is provided with a multiplicity of carts, a
reception terminal for receiving electric appliances from a first assembly line
on which the electric appliances were assembled, and an exit terminal for
releasing the appliances to a second assembly line after they are tested. The
reception and the exit terminals are connected with the assembly lines in
response to a run signal instructing the operation of the test line. When the
electric appliances are received at the reception terminal, they are each
mounted on one of the carts for circulation in intermittent movement in
response to the run signal. Located along the endless conveyor are a
multiplicity of test stations, which are adapted to carry out required tests
when the appliances are transported to the stations. Once a test is done on
an electric appliance, the same test will not be repeated on the same electric
appliance. The endless conveyor is disconnected from the assembly lines in
response to a stop signal instructing the stopping of the test line, so that the
conveyor becomes independent of the assembly lines and circulates the
electric appliances in the test line. When the test line receives the stop signal,
each of the electric appliances are allowed to make a complete circulation
through the test line, starting from the position located at the time of
reception of the stop signal, to complete pending tests, and then the test line
is stopped. The test line may be incorporated in an assembly line, thereby
improving the production efficiency of the lines.

Abstract: A phase measurement apparatus and method for measuring electrical
signal jitter and wander operates in real time and digitally controls bandwidths over
which the measurements are performed. The apparatus includes a digital phase-lock
loop (PLL) for generating phase difference signal data having first and second
frequency components above and below the loop bandwidth of the phase locked loop.
The PLL includes a digital signal processor (DSP), a direct digital synthesizer (DDS),
and a tracking oscillator, a phase detector, and an analog-to-digital converter (ADC).
The ADC digitizes the analog phase difference signal from the phase detector. The
DSP receives the digital data and performs a loop filter function for generating
frequency update values to the DDS for phase locking the PLL to an incoming signal.
The DSP performs an integration function on the loop filter function output to
generate the second frequency components. The first and second frequency
components are combined in a summing circuit and low and high pass filtered in
digitally programmable low and high pass filters for establishing measurement bands
for measuring the phase difference. A measurement processor includes a peak detector
and a summation accumulator for measuring peak-to-peak minimum and maximum
values and generating RMS values of the phase difference signal over a selected time
interval and generating an output in unit intervals for jitter and time for wander. The
DSP further includes low and high pass filter functions and an accumulator for
summing filtered second frequency components to generate wander data. The DSP
filter functions in combination with the digitally programmable low and high pass filters
having programmable filter breakpoints establish the measurement bandwidths. The
DSP processes the frequency update values to generate frequency drift data.
