Title: Piezoresistor effects in semiconductor resistors
IPC: H01L29/84
Filed: 1975-12-26
Abstract: In semiconductor integrated circuits, piezoresistance is recognized as a factor affecting production yield and circuit performance. Current flow in a circuit resistor is aligned with one of the <100> family of equivalent directions. When current is flowing along such a direction the change in resistance due to any combination of stress components is at a minimum. Additionally, variation of resistance due to stress and strain may be reduced by an increase of the total impurity concentration in a resistor.

Title: Energy conversion process and device.
IPC: F01K25/06
Filed: 1978-10-19
Abstract: The utilizable energy of a working fluid is converted into mechanical energy by means of friction forces exerted by the fluid on the moving walls of one or a number of circulation ducts forming part of a rotor. In their respective azimuthal projections, the friction force exerted on the fluid by the duct walls and the Coriolis force to which the fluid is subjected are of the same order of magnitude. The method consists in varying the pressure of the working fluid which is circulated in a spiral circuit and subjected to azimuthal displacements in the same direction of rotation as the rotor when the fluid comes closer to the axis and in the opposite direction when it moves away from the axis. When at least a portion of the duct walls forms part of a heat exchanger, the working fluid can also undergo predetermined variations in entropy and in enthalpy.

Patent ES-8204337-A1 (ES)
Title: Manufacture of composite shafts.
IPC: F16C3/02
Filed: 1981-06-16
Abstract: A method of applying a layer of resin and axial fibres to a workpiece such as an automotive propeller shaft during the manufacture of the shaft includes the steps of arranging a series of fibre feed stations around the periphery of the workpiece, causing the fibres from the feed stations to converge along a conical path with the workpiece where they are united with the workpiece by circumferentially wrapped fibres. Resin is applied to the cone of fibres by throwing it out under centrifugal force from a rotating annular groove when the fibres are sufficiently close together to support a layer of resin between adjacent fibres. As the fibres are then pulled on to the workpiece, good impregnation of the resin into the fibres is achieved.

Patent ES-8405493-A1 (ES)
Title: Hydraulic actuator arrangement.
IPC: F16D48/02
Filed: 1983-06-22
Abstract: A multiple plate clutch (33, 34) for a tractor PTO shaft (30) is engaged by an annular piston (37) when hydraulic fluid under pressure is supplied through a line (42). A pressure-responsive variable throttle valve (25) is included in the line (42) and is responsive to the downstream pressure applied via passages (51) to a spool (47) to register large and small grooves (50 and 53) respectively with a flow passage (45) when the said pressure is low and high respectively. This allows an initial rapid flow rate for taking up slack in the clutch but, by virtue of the narrow groove (53), limits the rate at which pressure builds up once the plates have started to engage. The clutch is thereby prevented from snatching. Another hydraulic line (43) feeds the annular piston (39) for a brake (38, 40, 41) on the PTO shaft 30. A two-way changeover valve selectively connects either of the hydraulic lines (42) and (43) to the pressure source and vents the other line to a sump.
