Abstract: Disclosed is a colorimetric sensor comprising polydiacetylene
membrane liposomes, a polydiacetylene membrane film or fine
particles coated with a polydiacetylene membrane, in which the
polydiacetylene membrane is incorporated with a protein having
a reduced molecular weight low enough not to cause color change
in the polydiacetylene membrane. The examples of the
reduced-molecular-weight proteins include an antibody Fab'
fragment, an antigenic protein of molecular weight of 100,000 or
less, and a peptide consisting of 3-20 amino acid residue, which
undergo an antigen-antibody reaction with an antigen or
antibody contained in a sample. As the reduced-molecular-weight
protein is also employed a combination of single-stranded
DNA of 100 bases or less which hybridizes with
single-stranded DNA contained in a sample to form a double-stranded
DNA, and an antibody which reacts with said double-stranded
DNA but does not react with the single-stranded DNA
contained in the sample. A method for analysis of biosample is
also disclosed, which comprises contacting the colorimetric
sensor with a solution sample and utilizing an absorption
measurement or a visual observation with the naked eye to
detect color change in the polydiacetylene membrane.

Title: Semaphore for a computer system
Inventor: LYSONS JOHN SPENCER MARSHALL
IPC: G06F9/52
Filed: 1999-02-10
Abstract: A computer system is described in which access to a shared
resource is controlled by a semaphore. The semaphore comprises
a lock value and a key value. When a process wishes to access
the shared resource, it calls a reserve function which
increments the lock value and stores the unchanged value of the
lock value in a local variable. The reserve function then
performs a loop in which it repeatedly compares the key value
with the local variable until they equal. When the process has
finished with the shared resource, it calls a release function
which increments the key value. This guarantees to allocate the
semaphore to processes in the order in which the processes
requested it (i.e. in chronological order), in a cheap and
effective manner.

Abstract: It is an object of the present invention to present a
method for producing an electron tube capable of preventing
agglomeration of particles contained in coating material to be
coated on an shadow mask to form an electron beam reflecting
film, that causes settling of the particles on a shadow mask
or clogging of the coating system, and fluctuations of
pressure for supplying the coating material to a spray nozzle,
that cause unstable quantity by weight of the coating material
discharged from the nozzle and excessive coating, thereby
preventing deterioration of the quality of images. An
electron beam reflecting film of high surface coverage can be
formed for the electron tube with a small quantity by weight
of the coating material containing bismuth oxide particles
which have an average particle diameter D50 of 0.6 µ m or less
and a particle size distribution with the particles having a
diameter between D40 and D60 accounting for at least 20% by
volume of the total particles. This method supplies the
coating material by oscillations of a piezoelectric element to
the spray nozzle, or scans the nozzle just by slanting the
nozzle at varying angles while keeping a head between the
surface of the coating material in a coating material storage
section and the nozzle center.

Abstract: The invention relates to a shoe lacing configuration
for an article of footwear such as a boot (1), where the boot
is provided with two rings (15), one ring supported on either
side of the boot proximate an ankle supporting portion of
the boot. A long strap (20) is looped through the two rings
such that the long strap defines an elongated C-like shape.
Each end of the long strap is formed with eyelets. A lace
extends through eyelets formed in the boot in a traditional
criss-cross manner, and the lace further extends through
the eyelets formed in the long strap. The long strap has
the effect of doubling the force applied to the lace in a
manner similar to that of a block and tackle thus improving
the lace tightening characteristics of the boot.

Abstract: A bipolar transistor and a field-effect transistor
having an electron quantum-wave
interference layer with plural periods of a pair of a well
layer W and a barrier layer B in a p-layer.
The well and barrier thicknesses are an odd
multiple of a quarter quantum-wave wavelength of carriers in
each of the well layer W and the barrier layer B, preferably
around the lowest energy level of the
barrier layer B. The quantum-wave interference layer
functions as an electron reflecting layer, and enables to
improve the amplification factor of an npn bipolar transistor
having such a quantum-wave interference layer formed in its
bax region. Similarly, a bipolar transistor having a hole
reflecting layer, which has a larger amplification factor,
can be obtained. A hole reflecting layer can moreover be formed
in the channel region of a field-effect transistor such as a MESFET.

Abstract: Self-cleaning printer having ultrasonics and method of assembling
same. The printer (10) comprises a print head (60) defining a plurality of ink
channels (70) therein, each ink channel terminating in an ink ejection orifice (90).
The print head also has a surface (85) thereon surrounding all the orifices.
Particulate matter (165) may reside on the surface and also may completely or
partially obstruct the orifice. Therefore, a cleaning assembly (170) is disposed
relative to the surface and/or orifice for directing a flow of fluid along the surface
and/or across the orifice to clean the particulate matter from the surface and/or
orifice. The cleaning assembly includes an ultrasonic transducer (205) in
commnication with the fluid for generating ultrasonic vibrations causing pressure
waves (207) within the fluid. Presence of pressure waves induce a hydrodynamic
force in the fluid. This force acts against the particulate matter to clean the
particulate matter from the surface and/or orifice. A pump (290) is also provided
for pumping the fluid from the surface and/or orifice as the surface and/or orifice
is cleaned. As the surface and/or orifice is cleaned, the particulate matter is
entrained in the fluid. A filter (300/310) is provided to separate the particulate
matter from the fluid.
