Patent EP-0250886-A2 (EP)
Inventor: JACKSON THOMAS NELSON
IPC: H01L29/812
Filed: 1987-05-29
Abstract: A heterostructure comprising a surface semiconductor layer (3) having a small band gap and being adaptable to planar processing supported on a high resistance accommodation layer (2) effectively eliminating possible low impedance parallel current paths is described. The accommodation layer has a larger band gap than the layer (3) and is of intrinsic conductivity type. The small band gap layer has its Fermi level pinned in or near the conduction band edge at surfaces and grain boundaries thereby providing barrierless current flow and eliminating the usually inherent barries formed with metal contacts. Furthermore neither the semi insulating substrate (1), the accommodations layer (2) or the small band gap layer (3) need to be single crystalline lattice matched or epitaxial specific examples of the invention comprise: 

     1. a superconductor normal super­conductor device of n-InAs-100 nanometers thick with niobium superconductor electrodes spaced 250 nanometers apart and a 100 nanometer gate in the space with the n-InAs being supported by an undoped GaAs layer on a semi-insulating GaAs substrate.   2. a heterojunction field effect transistor device having a GaAlAs gate over a channel 100 nanometers thick on an undoped GaAs layer on a semi-insulating GaAs substrate.

Abstract: A method is provided for reducing fatigue crack propagation in nickel base superalloys. The method involves a supersolvus anneal in which essentially all γʹ precipitate phase is dissolved. The supersolvus anneal is followed by slow cooling which is at a rate which substantially reduces time dependent fatigue crack growth but which preserves the strength of the alloy at a useful level for many superalloy applications.

Abstract: A spout (10) for providing a flow of water in the form of a sheet is disclosed. Water from a supply pipe (p) is diverted orthogonally in two directions as it enters a reservoir inside the spout. Water pooled in the reservoir (37) spills over a weir (46) to form a sheet-shaped flow stream as it flows down the weir. The weir has a raised section (50) which helps define a flow chamber (54) to promote and develop a stream which maintains a sheet shape even relatively great distances from the spout.

Abstract: An evaluation circuit for an inductive sensor, particularly a displacement sensor is proposed. This contains an inductance (L) dependent on the displacement to be measured. The inductance (L) is a component of a Wheatstone bridge (R1, R2, R3, L). The inductance (L) is associated with a switch (S). The bridge voltage (UA) is monitored by a comparator (OP). A microprocessor (MC) detects the time (T) between the actuation of the switch (S) and the zero transition of the bridge voltage (UA). The time (T) is proportional to the value of the inductance (L) but independent of the value of the supply voltage (UE.) <IMAGE>

Furthermore, the central gears (34, 35) are coupled as a synchronous drive by two back gears (37, 38) arranged on the back-gear shaft (36) in such a way as to fixed in terms of rotation, and the back-gear shaft (36) is rotatably mounted about the central gears (34, 35) and supported on the torque coupling (24) as a function of load. Furthermore, the reduction steps of the back gearing (31) correspond to the reduction steps of the multi-step gearing (51). 
<??>This design ensures that the drive motor (22) of the actuating drive (21) can rotate continuously at a constant speed and direction of rotation independent of the speed and direction of rotation of the machine spindle (3) and thus always delivers a uniform torque. A workpiece can be clamped and released by changing the direction of rotation of the actuating drive motor (22), and the clamping force acting on the workpiece is also easy to adjust.

Abstract: A hollow-profile spacer 30A has faces 27 which engage the glazing panes and can be bent to form a rectangular frame. The inner face 32 is perforated at 29 to allow dessicant material within the hollow profile to absorb moisture from within the space between the glazing panes. 
     The spacer is roll-formed from a flat strip of oriented thermoplastic material whose edges are welded together along the line 28. The material is highly-oriented in the longitudinal direction 34 which improves strength, stiffness and dimensional stability in this direction. It also reduces thermal conduct­ivity in the transverse direction 33. The sheet may be biaxially oriented so that it has dead bend properties both parallel (34) and normal (33) to the longitudinal axis of the spacer. 
     Alternatively the orientation of the material is achieved by drawing in the course of producing the spacer by extrusion.
