Title: Rotary blow molding machine
IPC: B29C49/36
Filed: 1988-03-09
Abstract: A rotary blow molding machine includes a base (12), 
a turntable (14) on the base (12) rotatable about 
a vertical axis and a number of mold units (20) spaced 
around the turntable (14). Each mold unit (20) includes

Title: Dual isotope scintigraphic image enhancement
IPC: G06T5/50
Filed: 1988-12-01
Abstract: An improved method of dual isotope subtraction 
scintigraphic image processing uses a band pass spatial 
frequency filter to smooth and enhance the image obtained 
with the less well resolved isotope and then applies the 
same filter function to the image from the better resolved 
isotope, after which the images are subtracted to produce 
an enhanced image with reduced edge artifacts and better 
resolution. The method can be applied to images where the 
target/background ratio approaches unity, and to single 
isotope imaging.

Title: Method and device for attachement of biologically useful materials to a solid phase
IPC: G01N33/543
Filed: 1989-06-08
Abstract: A method and kit for indirectly attaching a 
biologically useful material to a solid phase by means of 
a linking polymer is described. The linking polymer is 
selected from difunctional polyalkylene ether polymers 
wherein the difunctionality is at the distal and proximal 
ends of the polymer. The proximal end of the polymer is

polymer is joined to the material. Very low density of the 
linking polymer (less than 100 nanomoles per square 
meter) reduces interference with and increases the activity 
of the material. Enzymes and other active molecules or 
combinations of molecules are immobilized in the solid 
phase.

Patent EP-0355975-A3 (EP)
IPC: B60W30/18
Filed: 1989-07-13
Abstract: A feedback control system and method for 
controlling the wheel slip of a wheel driven by torque 
coupled through an electronically controlled 
hydraulically operable clutch (22) from an internal 
combustion engine. A first feedback variable related to 
wheel slip and a second feedback variable related to 
hydraulic pressure applied to the clutch (22) are summed 
(12) to generate a feedback control signal. In response 
to the feedback control signal, the clutch (22) is 
slipped by regulating the hydraulic pressure to reduce 
the driven wheel speed. Engine speed is adjusted in 
response to a measurement of driven wheel speed to 
prevent over-revving of the engine and maintain a 
desired predetermined positive torque on the driven 
wheel while the clutch (22) is being slipped.

Title: Hierarchical multiple bus computer system
Inventor: SCHWEIZER PAUL T
IPC: G06F15/17
Filed: 1989-10-19
Abstract: A modular and hierarchical multiple bus 
computer system architecture includes a master bus (1) 
and a slave bus (4) which are substantially identical, 
communication being effected through a combination of 
an interface controller (12) and a shared dual port 
RAM (14) responsive to a shared RAM controller (13). 
Thus processor engine modules including a bus, a 
processor, an interface controller, a shared dual port 
RAM, and a shared RAM controller are horizontally 
and/or vertically integrated at multiple levels 
without major restructuring of the composite system 
control operations by having each slave processor 
engine module interface as a peripheral upon the bus 
of its master. The modularity of the architecture 
allows the use of standard peripherals and platform 
processor engines to expand memory or increase 
functionality without burdening the master bus 
processor engine. Each slave bus processor engine is 
fully functional as an independent processor with 
mastery over its own bus. The architecture is 
particularly efficient in extended data base, fault 
tolerant data base or multi-communication system 
adapter interface functions.

Patent EP-0380939-A3 (EP)
Title: Resonant tunneling photodetector for long wavelength applications
IPC: H01L31/10
Filed: 1990-01-11
Abstract: In one embodiment of the present invention, a photo-­
detector is formed by coupling a highly doped cathode 
(112) to an anode (110) through an undoped quantum well 
(114) or superlattice filter structure. The absorption 
mechanism of a detector according to the present inven­
tion is free-carrier absorption in a heavily doped 
direct bandgap semiconductor (the cathode). The cathode 
material is preferably chosen such that the conduction 
band edge is lower than the conduction band edge of the 
material forming the well of the resonant-tunneling 
filter. The cathode material should also be semi­
conductor material of relatively narrow direct bandgap 
with low effective electron mass. 
A detector according to the 
present invention device is biased such that electrons 
pass through the filter structure by resonant tunnel­
ing. To stimulate conduction, incident radiation must 
have a frequency sufficient to 
boost the energy of the cathode electrons from the 
Fermi energy level of the cathode (112) to the re­
sonance energy level of the quantum-well filter. Thus, 
photons of incident radiation are absorbed in the 
cathode (112).  
     In a second, voltage-tunable, preferred embodiment of 
the present invention, a single quantum well filter 
 
 
having an undoped subband (218) is disposed between a 
doped cathode (212) and an anode structure. The single 
quantum well filter structure includes a quantum well 
(214) with one or more subbands (218) surrounded by two 
barrier regions (216). The detection frequency is 
changed by increasing or decreasing the bias slope of 
the conduction band which, in turn, moves the quantum 
well subband energy level relative to the cathode Fermi 
energy level.

IPC: H01L21/368
Filed: 1990-03-02
Abstract: The method of the present invention for forming 
a monomolecular membrane on a substrate comprises the 
steps of 
   (1) mixing 
   (a) at least one substance having a water-­
soluble polar head (hydrophilic portion) and a water-­
insoluble organic tail (hydrophobic portion) in the 
molecule, the head being ionizable into a cation when 
spread on water, and    (b) at least one substance having a water-­
soluble polar head (hydrophilic portion) and a water-­
insoluble organic tail (hydrophobic portion) in the 
molecule, the head being ionizable into an anion when 
spread on water, to obtain a mixture,      (2) developing the mixture on an aqueous subphase 
to form a monomolecular layer, and    (3) transferring the monomolecular layer to a 
substrate while applying a surface pressure to the layer.     
     According to the present invention, there can 
be formed a unidimensionally controlled membrane which 
develops a higher function than do the conventional two-­
dimensionally controlled membranes. Consequently, the 
method of the present invention can be applied, for 
example, to the formation of wiring patterns of a 
molecular level.
