Patent CA-2150499-A1 (CA)
Inventor: YANG RUI QING
IPC: H01L33/30
Filed: 1995-05-30
Abstract: The present invention relates to quantum well semiconductor light emitting devices such as lasers that utilize resonant tunneling for carrier injection and spatially-diagonal transitions between an energy state in the conduction band of one quantum well and an energy state in the valence band of the adjacent quantum well for light emission, resulting in much improvement in both radiative efficiency and carrier injection efficiency. An elementary structure of the invented devices comprises two spatially coupled quantum wells residing in conduction and valence bands respectively wherein the valence band-edge in one quantum well is higher than the conduction band-edge of the other quantum well. Each quantum well contains at least one energy state formed by the quantum size effect. Light emission occurs by the transition of electrons from the state which is higher in energy in the conduction band quantum well to the state in the valence band quantum well, and the emission wavelength is inversely proportional to the energy difference between the two states which can be easily tailored by adjusting quantum well thicknesses. Cascade emission is realized by periodically stacking many repeated elementary device structures.

Title: Snowshoes
Inventor: WELLMAN NORMAN KEITH
IPC: A63C13/00
Filed: 1995-11-17
Abstract: The snowshoe has a tubular oval shaped frame made up of one piece of aluminum. The front of the snowshoe is angulated upwards so as not to trip when walking. The decking is made from one solid piece of material. The decking is perforated all along the outer edges and eyelets are inserted. The decking is then attached to the frame by wrapping one continuous strand of material through the eyelets and then around the frame. The cross member, positioned between the toe and heel decking, is made of several strands of material wrapped across the top of the decking and around the frame. The strands are held in place by the cut out toe section of the decking, which is folded back over the cross member and riveted in place. This makes the cross member secure and prevents it from moving laterally.

Inventor: ARUNACHALAM PALANI
IPC: G01F1/84
Filed: 1993-03-24
Abstract: A Coriolis effect densimeter which produces density output data of improved accuracy by embodying the principal that the natural frequency of a vibrating tube filled with material decreases with an increase in the material mass flow rate. High accuracy output data is achieved by measuring the natural frequency of the tube as material flows therethrough, correcting the measured frequency to compensate for the decrease in natural frequency caused the material flow (mass flow rate) and using the corrected natural frequency in the material density computation.

Title: Low-power-dissipation cmos circuits
Inventor: FISCHER WILHELM CARL
IPC: H01L27/092
Filed: 1995-10-10
Abstract: In low-power-dissipation CMOS circuitry, conventional CMOS inverters are powered by a repetitively ramped power supply. Clock signals are needed in the circuitry for controlling data flow therein.

Title: Method for cutting belts that incorporate reinforcing inserts, and a cutter for belts of such a kind
Inventor: EHKIRCH ETIENNE
IPC: B26D1/04
Filed: 1996-03-14
Abstract: In a method for cutting belts that incorporate reinforcing inserts, in particular, conveyor belts that are of an armored elastomer, the belt (41) is first arranged between two clamping jaws (10, 13) before the clamping jaws (10, 13) are pressed against in order that the cut can be made; at the same time, a cutter (17) is guided along the clamping jaws (10, 13) and transversely to the longitudinal direction of the belt and through the material from which the belt is made, by means of a drive system.            In order to be able to cut all kinds of belts that incorporate reinforcing inserts, including those that have steel armouring, and in order to be able to do this quickly and in a manner that ensures the long service life of the cutting tool that is used, during the cut cutting process, the material from which the belt is made is cut on both sides by cutting edges (36, 37) of the cutter (17). The cutting edges (36, 37) subtend an acute angle and each cutting edge is either straight or curved convexly towards the belt (41). In this method, the cutter (17) centers itself automatically relative to the reinforcing inserts that are embedded in the belt (41).      Also proposed is a cutter for the armored bulkheads referred to.
