Title: Bandgap tuning of semiconductor well structure
Inventor: POOLE PHILIP J
IPC: H01S5/16
Filed: 1996-02-28
Granted: 2006-08-29
Abstract: In a method of bandgap tuning of a quantum well heterostructure wherein ions are implanted in the heterostructure by ion implantation, the ions are implanted so that different regions are implanted in such a way as to create different concentrations of defects. This provides varying bandgap energies to various areas of the heterostructure during a subsequent thermal treatment, which removes residual defects and initiates intermixing in the quantum well region to result in a structure having a selectively shifted bandgap.

Abstract: Thermally insulated compound profile for doors, windows, or facades.   The compound profile consists of metal profiles (5, 6) and insulating strips that are preferably of plastic and are joined to the metal profiles on the longitudinal edges. O the extent that the insulating strip or the insulating strips are connected to the metal profile so as to resist shearing, in the event that the metal profiles are subjected to uneven heating, the compound profile will curve out toward the side that is exposed to the greatest amount of heat. This sort of flexing is to be prevented.   This has been achieved in that, shear resistance is low, moves towards zero, or a coulisse {13) is incorporated within the longitudinal connecting area between the structural elements (2, 11, 5) that are joined.   The thermally insulated compound profile is used to manufacture the frames for doors and windows.

Abstract: Injection molding apparatus for multi-layer molding two materials with different injection temperatures having an insulative air space extending between front and rear heated melt distribution manifolds. Heated nozzles extending from the front manifold each have a central melt channel and one or more annular melt channels extending around it. Melt transfer bushings each having a central melt bore extend across the air space to convey melt from the rear manifold to one of the melt channels in each heated nozzle. In one embodiment, each melt transfer bushing has a head portion which provides a spacer between the two- manifolds, and an elongated stem portion which extends through a bore through the front manifold to one of the heated nozzles. An air space around the stem portion provides thermal separation between the melt from the rear manifold and the front manifold which is at a higher temperature.

Abstract: A wire clamp device affixed to an outer end of a bar in a wire tightener of the type having a stationary wire holding clamp at an opposite end of the bar. A carrier is mounted on the bar and is also provided with a wire holding clamp. The bar is provided with a jack rack and the carrier has a jack mechanism for forcibly driving the carrier toward the first wire holding clamp so as to pull end portions of two strands of wire held by the two wire holding clamps toward each other. The wire clamp device which also has a wire holding clamp is positioned to hold the strand held by the wire holding clamp of the carrier after it has been drawn towards the first wire holding clamp so that the wire holding clamp on the carrier may be released to allow the carrier to be reset to a position near the wire clamp device, after which the wire holding clamp on the carrier is again activated to grasp again the tightened strand which it had previously held. The carrier can again be driven toward the stationary wire holding clamp at the opposite end after release of the strand from the wire clamp device. The presence of the wire clamp device makes it unnecessary to temporarily fasten the strand being tightened by movement of the carrier in order to allow the carrier to be reset to a position for further tightening of the strand.

Abstract: The invention relates to a motor-drive position indicator for actuating a sequence shift, a change-over switch or a moving coil. To achieve this, a first circular scale is provided with symbols arranged thereon. Said symbols are allocated to each individual switching stage involved when changing from one motor-give working position to another. The first scale is swept by a first pointer which rotates at 360° each time switching occurs.      A second circular scale is also provided with symbols arranged thereon. Said symbols are allocated to each possible working position of the sequence shift or other.      The second scale is also swept by a pointer. The second pointer performs a rotational movement around an angle corresponding to the distance between two adjacent symbols on the second scale each time that switching occurs. Trailing pointers are arranged on both sides of the second pointer in such a way that one of them is pulled along according to the direction of rotation when the second pointer rotates. Both trailing pointers thus indicate the actual control range which is switched.
