Patent FR-2646290-A1 (FR)
Title: Semiconductor component of the Mesfet type with pseudomorphic heterojunction
Inventor: TARDELLA ARMAND
IPC: H01L29/778
Filed: 1989-04-25
Abstract: In a component of this type, the junction is formed by a first layer 1 of a binary III-V semiconductor material such as GaAs, by a second layer 2 of a ternary III-V semiconductor material such as GaInAs and by a third layer 3 of a ternary III-V semiconductor material such as GaAlAs. The material of the second layer exhibits a higher electron mobility than that of the material of the third layer, naturally has a different atomic spacing from that of the first and third layers, and it is grown epitaxially on the first layer so as to form a pseudomorphic layer thereon. According to the invention, there is furthermore provided, between the second and third layers, an interposition plane 6 of very small thickness of a doped ternary III-V semiconductor material different from that of the other layers, such as AlInAs, whose composition is chosen so that its atomic spacing is substantially the same as that of the material of the second layer. The band discontinuity of the heterojunction is thereby increased, which makes it possible to obtain both a higher cutoff frequency and a greater channel current, and is hence of interest for example in microwave amplification. This AlInAs plane may be produced in particular with the techniques known as "planar doping" or "delta-doping".

Title: Two-part fixing components joined together by breakable links
Inventor: LANOS JACQUES
IPC: F16B21/08
Filed: 1989-06-13
Abstract: The invention relates to a single component used to fasten several plates using just one tool and just one movement. It consists of a washer A with two notched helical planes and a central pin C, A and C being joined together by two connections D. The central pin C is provided with a screwdriver slot (non-limiting tool example) and two fins at one of its ends. At the other end there is a deformable clip. To fasten n plates, the user must pierce a hole in the n plates then forcibly drive the deformable clip side in. With the aid of a screwdriver the user generates a rotation at the pin C causing this same pin to rise (by virtue of the notched helical planes of the washer A and by virtue of the fins K on the pin C). The plates are clamped between the deformable clip and the washer A, and the clamping is irreversible. This component is intended (inter alia) for any fastening which does not require the high characteristics of a screw-nut, screw-dowel (plug) etc. system.

Title: Axial flow turbine for gas turbine engine
Inventor: HUBER FRANK W
IPC: F01D5/18
Filed: 1990-01-24
Abstract: The axial flow turbine includes a number of internally air cooled turbine blades each having a tip section mounted adjacent the shroud and defining with it a gap that is susceptible of leaking engine working medium. Each internally cooled blade has an airfoil surface exposed to the engine working medium defining a pressure surface and a suction surface. A device minimises the leakage by providing a buffer zone in the gap. The device includes an orifice located in the tip section adjacent the pressure surface. The orifice is skewed relative to the rotation axis of the blade for leading air from internally of the blade into the gap toward the pressure side of the blades. The stream of air discharging from the orifice defines a buffer zone.
