Abstract: A macroporous polymeric adsorbent (20) is used to remove oil mist and oil vapors from compressed air produced by an oil-lubricated air compressor (11) prior to feeding the compressed air to an air separation membrane system (22). The macroporous polymeric adsorbent (20), previously known only for its ability to extract low molecular weight volatile organic compounds from liquids and gases, retains its ability to extract the oil for extended periods of time and outperforms the commonly used activated carbon of the prior art.

IPC: G11B7/09

Abstract: An optical beam in a scanning device is focused on an information layer of a multi-layer optical record carrier. A focus control circuit keeps the focal point of the beam on the information layer. When the focal point jumps to another information layer, the focus control circuit does not monitor the so-called central aperture signal in order not to depend on the presence of information in the information layers. During the jump the characteristics of the feedback loop of the focus control unit are modified to avoid instabilities in the movement of the focal point during the jump. When the focal point is captured on the designated information layer, the characteristics of the feedback loop are restored.

Abstract: A method and apparatus for controlling the color of an article such as a paper web includes performing a comparison between target and measured reflectance values in numerous wavelength bands spanning the visible spectrum. The comparison quantifies correspondingly numerous errors that are modified by a non-linear operation, such as squaring, and then added together. The resulting sum is minimized by individually adjusting the application of a number of colorants to the article. The number of wavelength bands is greater than the number of colorants. This avoids metameric effects which are common in conventional systems that rely on three color space coordinates such as Hunter Laboratories L, a, b; C.I.E. L*, a*, b*; chromaticity x, y, z; and tristimulus X, Y, Z. Colorant response simulators enable the effects of changes in application of colorants to be tested while the actual application of colorants to the article is unchanged.

Abstract: A composite bump structure comprising the physical and electrical connections
between an integrated circuit element and substrate using a composite bump
comprised of a single polymer body of low Young's Modulus and a conductive
metal coating. When the bonded structure is formed the composite bump is
deformed and the low Young's Modulus of the polymer body allows a very
reliable bonded structure with very low bonding force. Due to the low Young's
Modulus there is little tendency to separate the connections after the bonded
structure is formed. The bond can be formed using thermocompression bonding,
ultrasonic bonding, application of heat or application of light. The bond can also
be formed using a non conductive adhesive between the integrated circuit
element and the substrate. The bond can also be formed with a conductive
adhesive coating on the composite bump. The polymer body may be covered by
a conductive metal coating formed at the input/output pads of an integrated circuit
element or substrate. The composite bump is formed using material
deposition, lithography, and etching techniques. A layer of soldering metal can
be formed on the composite bumps if this is desired for subsequent processing. 
     It is possible to use a conductive barrier metal coating covering the polymer
body and a soldering metal coating covering the conductive barrier metal
coating. When the bonded structure is formed the composite bump is deformed
and the low Young's Modulus of the polymer body allows a very reliable bonded
structure with very low bonding force. Due to the low Young's Modulus there is
little stress tending to break the solder joint after the bonded structure is formed.
The bond is formed using a soldering process so that the soldering metal forms
a conductive adhesive between the composite bumps and either the substrate
input/output pads or the integrated circuit element input/output pads.

Abstract: The method for driving a stepping motor for printers comprises the
generation of first pulses (16A,16B) at n levels recorded in registers and
representing a simulation of sinusoidal waves. The maximum level is applied
during two consecutive microsteps to one of the phases of the motor, while
the level of the other phase changes sign. During a motor stopping
command, second pulses (VCA,VCB) are applied to the registers and to the
two phases of the motor and are programmed so as to ensure, during the
last microstep, an exact stopping position, such that all the stopping
positions are kept apart by a whole number of half steps. Very precise, fast
and noise-free printing is thus attained. The resolution is doubled, without
any loss of precision or speed.

computer program for any type of program that needs to be metered. The
object metering framework includes core function and extensible function.
core classes and core class relationships define the core function of the
framework mechanism. The extensible function is defined by extensible

Abstract: On a silicon substrate is formed a silicon dioxide film and
then hemispherical grains made of silicon, each having an
extremely small diameter, are deposited thereon by LPCVD.
After annealing the hemispherical grains, the silicon dioxide
film is etched using the hemispherical grains as a first dotted
mask, thereby forming a second dotted mask composed of the
silicon dioxide film. The resulting second dotted mask is used
to etch the silicon substrate to a specified depth from the
surface thereof, thereby forming an aggregate of semiconductor
micro-needles. Since the diameter of each of the semiconductor
micro-needles is sufficiently small to cause the quantum size
effects as well as has only small size variations, remarkable
quantum size effects can be obtained. Therefore, it becomes
possible to constitute a semiconductor apparatus with a high
information-processing function by using the aggregate of
semiconductor micro-needles (quantized region).

Abstract: An improved charge pump circuit includes one switch element driven by a ramp
waveform to precisely control the output voltage. The circuit includes a switch group
(130) having one or more switch elements for transferring a charge to one or more
capacitors (C1), a feedback circuit having an error amplifier (126) for amplifying a
difference between a divided output voltage and a reference voltage (V ref), a
compensation circuit (131, 132) for phase compensating the feedback network, an
oscillator (127) for generating the ramp waveform, and a control circuit (128) for driving
the one or more switch elements. At least one of the switch elements has a resistance
that can be adjusted externally and is driven by the ramp waveform such that its
resistance varies with time. Accordingly, the charge transferred from a power source
(VDD) to the one or more capacitors (C1) can easily be adjusted. When the charge
transferred is small, the on-time of the ramp waveform is short and the average value of
the resistance is large. The average resistance of the switch group varies when the
voltage of the power source varies, so that an output with a fixed voltage and low ripple
voltage can be obtained.
