Title: Self positioning beam mounted bearing and bearing and shaft assembly including the same
Inventor: IDE RUSSELL D
IPC: F16C33/10
Filed: 1992-09-24
Abstract: ABSTRACT      A bearing and a shaft and bearing combination for replacing conventional rolling element bearing, washer and lock ring assemblies.  The bearing is constructed so that it can be precisely positioned with respect to the shaft in the housing.  Additionally, the bearing provides both radial and thrust support so that the need for separate bearings is eliminated.  The assembly is ideally suited for use in small high speed low load cooling fans used in computers, peripherals and other office equipment.      The shaft includes a radially inward extending groove, preferably conically tapered. The bearing includes a base member, which can include a beam mounted radial bearing, and a number of longitudinal beams extending axially away from the base member.  Each of the longitudinal beams supports a bearing pad in a cantilever fashion.  The bearing pads include a shoulder or radially inward projection having a shape which is complementary to the shape of the groove in the shaft such that the pad shoulder can support the groove faces. t The longitudinal beams are resilient enough to allow the pads to be assembled over the shaft.  When the pads are assembled over the shaft and the pad shoulders are received in the groove, the bearing is precisely positioned with respect to the shaft.

Patent CA-2088725-A1 (CA)
Inventor: LITCHFORD GEROGE B
IPC: G01S13/933
Filed: 1993-02-03
Abstract: The range from which a collision avoidance system at an Own station can receive  secondary surveillance radars (SSR) interrogations and reply messages from Other stations, is extended by utilizing P2 pulses for timing time of arrival (TOA) measurement in the event P1-P3 pulse pairs are unavailable from the scanning main beam or its side lobes.          The amplitude of the P2 pulses in the SLS radiation pattern being greater than the P1-P3 side lobes of the main beam over an angular sector of about 60° centered on the main beam can insure reception of P2 pulses at much greater ranges than P3 pulses contained in the main beam side lobes can be reliably received.  Using P2 timing, interlaced Mode A and Mode C reply messages contained in a main beam burst reply sequence are separated into two "families" of TOAs, the Mode C (altitude) TOAS always being longer than the Mode A TOAs by 13 µsec. A " true" TOA is obtained by subtracting an appropriate time period from the TOA of each family, from which identity, altitude and range information is readily derived.  The system continuously adapts to the best instantaneously available timing pulses, alternating between P3 timing and P2 timing throughout the time it takes for a main beam rotation of the received SSRs, thereby extending the operation area of multiple TOA measurements from multiple SSRs which, in turn, provides added safety and reduced false alarms compared to prior passive collision avoidance systems.
Patent CA-2093387-A1 (CA)
Title: Medical device package
Inventor: BRICHACEK ROBERT J
IPC: A61M5/00
Filed: 1993-04-05
Abstract: A package  assembly  for  a  medical  device  comprises  a container  for  the medical device,  a generally cylindrical hollow tube with distal and proximal ends and a sidewall. The  external  side  of  the  container  has  an  outwardly extending rim at its proximal end.  The packaging assembly further includes a generally cylindrical hollow tube with an open bore.  The bore has a proximal portion and an adjacent distal portion at an interface.  The tube has a rim with a generally planar surface extending outwardly at the proximal end.  The container is sized so that its distal end fits in to the open bore of the tube. The tube proximal portion is sized to accept the rim of the container.  The tube distal portion is sized so that the container is allowed passage up to its rim.   The inner surface of the proximal portion of the tube has an inward projection which allows the rim of the container to pass over it when the container is moved distally, but is shaped to resist passage of the rim with proximal movement of the container.  The design of the tube makes  it  unlikely  that  the  tube can  be  unintentionally removed from the shield, thus providing a secondary barrier to needle sticks if the needle should penetrate the needle. The tube  flange  is preferably provided with a barrier to passage of microorganisms.

Title: Field effect transistor and method of manufacturing the same
Inventor: MATSUZAKI KEN-ICHIRO
IPC: H01L29/10
Filed: 1994-02-21
Abstract: ABSTRACT OF THE DISCLOSURE      This invention provides a high-speed FET with a sufficiently high output current, and an FET having a high mobility of channel electrons and a high electron saturation rate.  For this purpose, in this invention, a buffer layer, a first channel layer, a first spacer layer, a second channel layer, a second spacer layer, a third channel layer, and a capping layer are sequentially epitaxially grown on a semi-insulating GaAs semiconductor substrate. Drain and source regions are formed, and a gate electrode is formed to Schottky-contact the capping layer.  Drain and source electrodes are formed to ohmic-contact the drain and source regions.  Extension of a surface depletion layer from the substrate surface to a deep portion is prevented by the third channel layer closest to the substrate surface.  For this reason, a sufficient quantity of electrons for forming a current channel are assured by the second and first channel layers.
