Title: Semiconductor light emitting device
Inventor: YAGI TETSUYA
IPC: H01L33/30
Filed: 1991-12-18
Abstract: An AlGaAs/GaAs system light emitting device comprises a GaAs substrate doped with a first conductivity type impurity, a first conductivity type AlyGa1-yAs first cladding layer, an AlxGa1-xAs (0 < x < y) active layer, and an AlyGa1-yAs second cladding layer having a conductivity type opposite to the first conductivity type, which are successively disposed on the substrate.  The light emitting device further comprises an AlzGa1-zAs (z  0) buffer layer which is disposed between the GaAs substrate and the first cladding layer, to which a first conductivity impurity is doped to such a high dopant concentration that the intensity of photoluminescence light generated due to band to band transitions is reduced, and has a smaller energy band gap than the energy of the light emitted from the light emitting device.  Therefore, a long lifetime semiconductor light emitting device having no sub peak in the light emission spectrum can be easily produced with good yield.

Abstract: ABSTRACT                      FOOD PRODUCT    A sheet of proteinaceous product is produced by comminuting heat-coagulable meat without substantially heat-coagulating the meat, and applying a layer of the comminuted (but still heat-coagulable) meat to a heated roller, or other suitable surface. The heat coagulates the meat to form a sheet, which can then be removed for example  by  a  doctor blade. Under  appropriate conditions, a ripple effect may be formed. The sheet can be folded and subsequently processed, for example into chunks for use in petfood.
Patent CA-2065729-A1 (CA)
Inventor: PEIFFER JAMES E
IPC: A61B17/122
Filed: 1990-09-14
Abstract: Disclosed is a cartridge (10) having a plurality of compartments (14) for holding preformed hemostatic clips (30). Each compartment (14) is dimensioned wide enough to hold a clip (30) and to allow a clip applicator (16) to be inserted without deforming the walls (46) of the compartment (14). Each compartment (14) has a center post or pedestal (50), smaller than the inside dimension of a clip (30), that loosely supports a clip (30).       Centering protrusions (44A, 44B) are positioned symmetrically along the sides of the pedestal (50) and along the walls (4t) of the compartment to help center the clip (30) within the compartment (14). Each clip (30) is held in place by two fingers (20) that extend into the ends of the compartment (14) and contact the clip (30) to positively retain the clip (30) at all times. A "V" shaped groove (70) is formed into the end of each finger (20), which helps hold the clip (30) in the center of the compartment (14).

Title: Hydraulically actuated releasable connector and method for setting oil well liner
Inventor: MIMS MICHAEL G
IPC: E21B17/06
Filed: 1990-10-08
Abstract: A hydraulic setting and release tool (10) has a shear out setting assembly (12) attached to a string coupling member (14). Upon reaching a predetermined hydraulic pressure, a piston (20) of the tool (40) shears restraining shear pins (22) and moves in a body of the tool to release dogs (15) that engage the coupling member (14). When the dogs (15) release, springs (16) retract the dogs (15) from engagement in sockets (34) of the coupling member (14) and the shear out setting assembly (12) separates from the coupling member (14). When used in running in a liner, the coupling member is a running head (14) that rotates the liner during running in and cementing. When used as a drill string release tool, the coupling member is a release sub (44), the tool (10) being placed serially with other string components. If the drill string gets stuck, it is separated by merely increasing the hydraulic pressure sufficiently to shear the pins (22) and allow the piston (20) to move and the dogs (15) to retract to separate the release sub from the shear out assembly (12).

Patent CA-2076774-A1 (CA)
IPC: H01L23/467
Filed: 1992-08-25
Abstract: PIN FIN HEAT SINK INCLUDING FLOW ENHANCEMENT Abstract Heat dissipation performance of a pin fin heat sink is improved by utilizing a flow guide arrangement. Flow guide members are positioned relative to the outer rows of the pin fins and longitudinal to fluid flow through the pin fin field of the heat sink. A gap between a lower edge of each flow guide member and a base surface of the heat sink forms apertures allowing potentially stagnant fluid in an interior region of the pin fin field of the heat sink to communicate with fluid flowing around the exterior of the heat sink. This causes a so-called "pump" action in which the potentially stagnant fluid is drawn along with the fluid flowing around the exterior of the heat sink. (FIG. 5)
