Abstract: A nitride semiconductor laser device of high reliability such that the width of contact between a p-side ohmic electrode and a p-type contact layer is precisely controlled. The device comprises a substrate, an n-type nitride semiconductor layer, an active layer, and a p-type nitride semiconductor layer. All the layers are formed in order on the substrate. A ridge part including the uppermost layer of the p-type nitride semiconductor layer i.e., a p-type contact layer is formed in the p-type nitride i.e., a p-type contact layer is formed in the p-type nitride semiconductor layer. A p-side ohmic electrode is formed on the p-type contact layer of the top of the ridge part. A first insulating film having an opening over the top of the ridge part covers the side of the ridge part and the portion near the side of the ridge part. The p-side ohmic electrode is in contact with the p-type contact layer through the opening. A second insulating film is formed on the first insulating film.

Title: Mining machine and method
Inventor: HAINSWORTH DAVID WILLIAM
IPC: E21C41/18
Filed: 2001-04-23
Abstract: A mining machine (7) is provided which moves from side-to-side in sequential passes across a seam of material to be mined. The machine (7) is carried on rail means (19) and co-ordinate positions of the rail means (19) are measured at locations along the length of the rail means. A trailing part of the rail means (19) is then moved by rail moving means (25) to a new position for a next pass, and the distance of moving is determined from the co-ordinates of the positions previously measured. By knowing the co-ordinates of the positions, the rail means (19) can be moved to assume a desired profile, so that a desired profile of the face of the seam can be achieved on the next pass of the machine (7). Desirably the profile is a straight line. Co-ordinates of the up and down movement of a shearing head (9) can also be measured and stored with the co-ordinates of the positions along the rail means to provide a profile of the seam being cut, and so that on a next pass the intended position of the shearing head (9) can be predicted and moved accordingly. A method of mining embodying the above is also provided.

Title: Shape memory polymers seeded with dissociated cells for tissue engineering
Inventor: KNISCHKA RALF
IPC: B29C61/06
Filed: 2001-05-31
Abstract: Methods and compositions are described herein for reconstruction of different functional tissues. Dissociated cells, differentiated cells, adult mesenchymal stem cells or embryonic stem cells are seeded on a scaffold. The scaffold will consist of a biocompatible, biodegradable shape memory ("SM") polymers. In addition bioactive substances may be incorporated in the scaffold.  Thermoplastic as well as thermoset materials with SM-effect can be used. The shape memory effect will be applied as an interactive link between the cells and the used polymeric scaffold. The degradation kinetics as well as shape memory transition temperature will be tailored by adjusting to monomer ratios of the co-oligomers. The shape memory effect will be used to create a degradation or release of bioactive substances on demand, induce forces on seeded cells or induce proliferation and differentiation of cells.

Title: Oximeter sensor adapter with coding element
Inventor: FEIN MICHAEL E
IPC: A61B5/00
Filed: 2001-09-21
Abstract: An oximeter sensor adapter which allows a sensor without a resistor in parallel with its LEDs to operate with an oximeter expecting such a resistor in parallel. The adapter includes LED drive electronics and appropriate oximeter drive current sensing circuitry for converting the drive signals from the oximeter into appropriate LED drive signals for the sensor. Instead of a resistor being on the sensor in parallel with one or more of the LEDs, the resistor is placed across the leads in front of the LED drive electronics and oximeter drive current sensing circuitry, on the oximeter side of the adapter.  By providing LED drive electronics and oximeter drive current sensing circuitry which do not draw significant current at a low voltage, the oximeter is able to measure the resistor independently just as if it were in parallel with the LEDs.
