Title: Sterilant concentrate injection system
IPC: B65D77/22
Filed: 1989-02-17
Abstract: A tubing system (18) connects a source (10) of tap water with a container (20) holding an item to be sterilized. Powdered buffers, detergents, and corrosion inhibitors are deposited in a well (34) along with an ampule (46) containing a sterilant, such as peracetic acid. The ampule includes an exterior wall (80) which defines an interior volume (82) and a linear vent passage (84) extending from the exterior wall to a central region of the interior volume. A gas permeable liquid impermeable membrane (100) is mounted across a vent aperture (86) which is disposed adjacent the geometric center of the interior volume. The volume is filled less than half way full with the liquid sterilant such that in all orientations of the ampule (FIGURES 4A-C) an upper surface (98) of the sterilant remains below the vent aperture. A pump (50) recirculates the water through the container, the tubing system, and the well to dissolve the powdered reagents. A tubular needle (70) of an aspirator system (42) is moved along the vent passage and through the vent aperture such that its free end is immersed in the sterilant. An aspirator (44) draws the sterilant from the ampule into the tubing system, mixing it with the recirculating water.

Title: Production of poly(phenylene sulfide) of an improved reactivity
IPC: C08G75/0209
Filed: 1989-11-21
Abstract: A poly(phenylene sulfide) material containing predo­
minantly para-phenylene sulfide structural units and having 
a melt viscosity of at least 5 poises (at 300°C) may be 
treated or reacted with an alkali metal sulfide and/or 
hydrosulfide in a polar aprotic solvent at a relatively low 
temperature in the range of 150 - 230°C so as to introduce 
an increased amount of reactive thiolate or thiol end groups 
to the polymer molecule and hence to enhance the reactivity 
of the polymer material. The thus modified and highly reac­
tive poly(phenylene sulfide) material exhibits an improved 
compatibility with other polymers and is expected to be 
useful in preparation of polymer alloys of improved or 
modified physical and chemical properties.
Patent EP-0380881-A3 (EP)
Title: Protection circuit for a power mosfet driving an inductive load
IPC: H01L27/04
Filed: 1989-12-20
Abstract: A snubber circuit comprising two stages 
regulates the gate current of a MOSFET (12) in 
relation to the drain-to-source voltage at turnoff to 
clamp transient inductive voltages to a 
nondestructive level. At the onset of the turnoff, a 
current source (28) is activated to discharge the 
gate capacitance, and the snubber circuit controls 
the magnitude of such current in relation to the 
sensed drain-to-source voltage to stabilize the 
drain-to-source voltage at a nondestructive level. 
When the drain-to-source voltage approaches its limit 
value, a current injection circuit (76) supplies 
additional current to the gate (g) to sustain the 
MOSFET conduction, again in relation to the sensed 
drain-to-source voltage. When the inductive energy 
stored in the load (14) is substantially dissipated, 
the drain-to-source voltage falls; at such point, the 
current injection circuit (76) is disabled and the 
conduction of the current source is increased to 
complete the turnoff of the MOSFET.
Patent EP-0376722-A3 (EP)
Title: Bipolar sinker structure and process for forming same
IPC: H01L29/08
Filed: 1989-12-28
Abstract: A sinker is P which is self-aligned with the oxide 
isolating trench which is used to define the tub in which 
the complete bipolar device is located. In a preferred 
approach to the process for forming the sinker of this 
invention, an initial definition of the isolating trench 
only cuts the trench down to the top surface of the buried 
layer. The walls of the trench are doped, and the sinker 
diffused laterally through the sidewalls of the trench so 
that a sinker that is self-aligned with the isolating 
trench is created from the surface of the epitaxial layer 
in which the remainder of the bipolar device has yet to be 
defined down and into the buried layer. The trench is then 
defined for the remainder of the desired depth down through 
the buried layer and into the substrate layer below the 
buried layer. Thereafter, the device is formed in the tub 
preferably with the collector adjacent the trench and 
thereby aligned with the sinker. By following this 
sequence, little additional diffusion of the sinker occurs 
during subsequent processing, whereby an effective sinker, 
aligned with the collector of the bipolar device, is 
achieved without additional masking steps.  
     In an alternative approach, a hole may be cut in the 
surface oxide to define the area where the trench will be 
cut, but cutting of the trench is preceded by a diffusion 
of the sinker through the same hole. The sinker diffuses 
downward through the epitaxial layer to the buried layer, 
and also diffuses laterally to extend somewhat beneath the 
oxide immediately adjacent the trench and beyond the region 
where the trench will be defined. The trench is then cut 
in a single step through the epitaxial layer and the buried 
layer and into the underlying substrate, cutting directly 
through the region in which the sinker has been previously 
diffused. However, because of the lateral diffusion of the 
sinker, a portion of the heavily doped region which shall 
 
 
function as the sinker remains, now self-aligned with the 
edges of the tub defining trench.

Title: Time resolved optical array detectors and ccd cameras for frequency domain fluorometry &/or phosphorimetry.
Inventor: GRATTON ENRICO
IPC: G01N21/64
Filed: 1993-11-17
Abstract: An apparatus for cross-correlation frequency domain fluorometry-phosphorimetry comprises a source of electromatic radiation and means for amplitude modulating the radiation at the first frequency. The amplitude modulated radiation is directed at a sample, while an optical array detector measures the resulting luminescence of the sample. A signal is provided coherent with the amplitude modulated electromagnetic radiation signals, at a second frequency which is different from the first frequency. The apparatus has the capability for shutting off and turning on the coherent signal at the second frequency in a cycle having a third frequency which is different from the difference between the first and second frequencies. This produces a resultant signal at a frequency derived from the frequency difference and the third frequency. Typically the resultant signal is no more than about a quarter of the frequency difference. The resultant signal modulates the gain of the detecting means or multiplies its output, depending upon the nature of the detecting means. The amount of luminescence measured by the optical array detector is read when the signal is off in its cycle of the third frequency. <IMAGE>
