Patent CA-1315420-C (CA)
Title: Modification of interfacial fields between dielectrics and semi-conductors
Inventor: ARONOWITZ SHELDON
IPC: H01L21/316
Filed: 1988-09-20
Granted: 1993-03-30
Abstract: ABSTRACT OF THE DISCLOSURE         Reduction in the net charge at the interface of a dielectric and a semiconductor material is achieved by placing atomic species in the dielectric near the interface.  Preferably, these species are selected from the group of alkaline earth metals.  The presence of these atoms results in a redistribution of the electronic density near the interface.  The placement of the atoms is effected by ion implantation followed by multiple annealing steps at alternating low and high temperatures.

Abstract: VIDEO TUMOR FIGHTING SYSTEM                  Abstract of the Disclosure A destructive heat lesion is placed in any location in the brain.  A patient's head is secured within a stereotactic frame.          After a high resolution CT scan and angiogram or MRI, data is incorporated and analyzed by a computer.  This information is then resynthesized and projected as a video image on a screen facing the surgeon.  A small metal object, perhaps a ball, is inserted into the patient's head via a burr hole drilled through the patient's skull.  Using real time fluoroscopic data super-imposed on the the computer image of three-dimensional structures, the surgeon is able to control and manipulate the object through the patient's soft brain tissue to a position next to or inside of the tumor area.  An energy beam is then fired at the object, causing the more heat efficient object to destroy the brain tumor area.  This procedure is repeated until the entire tumor is eradicated by the highly localized hyper-thermia.  The above procedure can be used to deliver hyper-thermia, chemotherapy, radiothrapy and other agents or treatments to the brain and other parts of the body as well.

Title: Hearing aid employing a viscoelastic material to adhere components to the casing
Inventor: KOLPE VASANT V
IPC: H04R25/02
Filed: 1989-08-02
Granted: 1994-02-08
Abstract: ABSTRACT         The invention significantly reduces noise amplified by the receiver of a hearing aid by better isolating the receiver from the casing and also by better isolating the microphone from vibrations of the casing.  The invention also helps to protect components of the hearing aid against damage when dropped.          Briefly, the invention concerns a hearing aid having a casing containing a transducer and a viscoelastic layer adhering the transducer to the casing, which layer has, at a frequency of 1000 Hz and a temperature of 100°F (38°C), a loss factor of at least 0.5 and a shear storage modulus G' of at least 107 dynes/-cm2.  Preferably the dynamic shear loss modulus G" (i.e. the product of the loss factor and the dynamic shear storage modulus G') is at least 1.5 x 107 dynes/cm2 in order to provide good isolation of the microphone.  Even better isolation is achieved when the dynamic shear loss modulus G" is at least 2.5 x 107 dynes/cm2 at 1000 Hz and 38°C.

Abstract: ABSTRACT OF THE DISCLOSURE   An optical correlator according to the present invention generates a cross-correlation peak of two patterns of pictorial information to be compared.  It generates pictorial patterns of a sum of the two patterns of pictorial information and of a difference between the two patterns of pictorial information by a phase conjugate waveform, transforms the pictorial patterns into first Fourier transform images, generates a pictorial pattern of a difference between an intensity distribution of the first Fourier transform images by the phase conjugate waveform, and transforms the pictorial pattern of a difference between an intensity distribution of the first Fourier transform images into second Fourier transform images.  The optical correlator detects a cross-correlation peak of the two patterns of pictorial information for comparison at a high S/N ratio.

Title: Pulsed coulometric detection with automatic rejection of background signal in surface-oxide catalyzed anodic detections at gold electrodes in flow-through cells
Inventor: JOHNSON DENNIS C
IPC: G01N27/48
Filed: 1989-09-25
Granted: 1992-05-12
Abstract: Abstract of the Invention A variation of Pulsed Coulometric Detection  (PCD) is described in which the detection potential is scanned in a cyclic fashion during current integration to achieve automatic  and virtual  elimination  of baseline  draft caused by surface roughening and changes in pH.   The technique is examined at a Au electrode for flow-injec-tion  determination  if  thiourea which  is typical  of numerous sulfur compounds whose anodic reactions are catalyzed by formation of surface oxide.  The baseline decays quickly to a near-zero equilibrium value follow-ing start-up and is unchanged for a pH step of ca. 2 units.   The technique is concluded to be compatible with pH-gradient chromatography.

Abstract: ABSTRACT    A  normally  rigid  planar framework for  mounting  a  large number  of ground working tools is made resilient to  accommodate the  torsional forces exerted on the rigid structural members  of the  framework as it passes over uneven ground and the tools  are subjected  to  varying forces as they move  through  the  ground.          Resilience of the framework is achieved by having the  structural members  which are normally rigidly fastened  together,  fastened together  instead by resilient fastening which permits  torsional flexing  between  the rigid members so  fastened.   Additionally, rigid  structural  members of the framework  which  normally  are pivotally  connected to permit movement only around the pin  axis of the pivotal connection, are resiliently pivotally connected so that  slight rotation of the structural members can occur  around the other two axes which intersect the pin axis of the respective pivotal connections at mutual right angles.

Abstract: In a pump apparatus in which the action of a piston draws fluid into and pumps fluid from a valve chamber,  a partition is provided between the piston cylinder and the valve chamber.  The partition is able to transmit the force of the piston action, and for this purpose the cylinder side of the partition contains a suitable liquid medium that transmits the actuation of the piston.  A screening means is provided in a passage between the partition and the valve chamber to screen out particles in the fluid that exceed a prescribed size. The overall effect is to eliminate wear to working parts of the valve caused by entrained particles.  In addition there  is  a  valve  device  which  prevents  bounce  or vibration of valve-pieces during high pressur/high speed pumping operations.

Abstract: A packet communication system which is suitable for higher speed bus, and a method of controlling the system.  A data bus is divided into a control bus for receiving data for contention control and a transmission bus for receiving only communication data including destination data, and each terminal interface transmits the contention control data to the control bus in the transmission cycle prior to transmission of its packet to perform contention control and thus to previously acquire the exclusive occupation authority of the transfer bus. Each terminal interface finishes the contention control in a one-cycle previous data transmission cycle to previously make a reservation for the use of the bus, and outputs the packet following the destination terminal interface address DLA onto the transmission bus in the next data transmission cycle.
