Patent ES-347770-A1 (ES)
Title: Couplings for tubes,bars and the like
IPC: E04B1/58
Filed: 1967-11-29
Abstract: A rod coupling, for securing a, preferably tubular rod 2 to a carrier 1, e.g. in a geodetic framework comprising carriers in the form of rings or curved anchoring rods from each of which a plurality of rods radiate, comprises a U-shaped link 3 which embraces the carrier 1 and whose arms are provided with groove formations adapted to interlock with a key formation on a body 6 or 6a which is fixed to the end of the rod 2, disassembly being prevented by a sleeve 4 or 4a which is held in position against the body or rod 2 by a wedge 7 inserted between the arms of the link 3, removal of the wedge allowing the sleeve to be slid to a position allowing dismantling of the body from the link. The wedge also acts on a shoe 11 having arcuate surfaces which match those of the carrier 1 to simultaneously clamp the assembly to the carrier, a second shoe 10 facilitating this in the embodiment of Figs. 1 and 3. In the embodiment of Fig, 5, the wedge can be rotated to the position shown instead of being withdrawn. The wedge either has an enlarged head 7c at its thin end or has an aperture 18 for a peg, to prevent complete withdrawal. A second aperture 17 may receive a peg to lock the wedge in operative position. In another embodiment (Fig. 4, not shown) the carrier 1 is of square cross-section and thus cannot normally rotate within the link 3, arcuate cut-away portions 9 formed in the link arms however allowing such rotation after the wedge has been removed to allow the carrier to be located between these portions.
Patent ES-373627-A1 (ES)
Title: Semiconductor devices
IPC: H01L27/04
Filed: 1969-11-17
Abstract: In a semi-conductor resistor comprising a body containing electrically active impurities to provide free charge carriers and electrically inactive impurities to reduce the temperature coefficient, the inactive impurities consist for a substantial part of neutral impurities. The neutral impurities may be elements such as Pb or Sn in Si, Ge or a mixed crystal of Si or Ge, or Al in GaAs. Alternatively the semi-conductor may contain a normally active impurity introduced in such a concentration and in such a way that a proportion of the atoms act as neutral impurities. Crystal dislocations produced by electron bombardment may also be used as neutral impurities. The resistor may be integrated in a wafer together with other devices such as transistors. In a first method an N-type Si wafer is provided with an oxide mask exposing a strip which is to form the resistor with an enlarged contact region at each end. Sn is diffused into the exposed area from the gas phase followed by a drive-in step. Boron is then diffused-in to form a P-type region. The wafer is then reoxidized, the contact regions are exposed and are provided with Al contacts to which conductors may be connected. In a second method an N-type Si wafer is provided with an oxide mask exposing contact areas for the resistor. B is diffused-in to form the contact regions and the resistor strip is exposed. Al is vapour deposited and processed to form contacts to the major portions of the contact regions. Ga69 is then introduced into the resistor strip and also the non-contacted parts of the contact regions by ion implantation. The wafer is then annealed. A proportion of the implanted ions act as active impurities to provide the current carriers and the remainder act as neutral impurities. In a modification, after deposition of the Al layer the resistor strip is exposed by etching away the Al and oxide layers. Ga is then ion-implanted and the excess Al is etched away leaving the contact lands. In a further method an N-type Si wafer is provided with an oxide mask exposing contact lands for the resistor. B is diffused-in to form the contact regions, the oxide layer is removed and the wafer is reoxidized. Smaller apertures are formed in the oxide layer over the contact regions, Al is vapour deposited and the resistor strip is etched in the Al layer only. B11 ions are then implanted through the oxide layer to form the resistor, the Al layer acting as a mask. The excess Al is then etched away leaving contact lands and the wafer is annealed.

Abstract: A self-pumping, hydropneumatic, telescopic, spring damping device with internal level regulation, especially for automotive vehicles, includes an oil filled working chamber and a working piston with damping devices, the working piston rod being hollow and forming a pump chamber for a pump rod which automatically pumps oil from an oil reservoir into the working chamber. A control opening permits flow from the work chamber to the oil reservoir when the desired oil level is exceeded. A gas cushion in a gas spring chamber connected with the working chamber pressurizes the oil in the working chamber. The gas spring chamber includes a separating piston and is connected axially to the working chamber in the region of a flexible or elastic partition which supports the pump rod. The partition includes communicating passages. A pump suction tube communicates a pump rod cavity with the oil reservoir, and is yieldable with respect to movements of the flexible partition. The separating piston of the gas spring chamber is recessed such that upon disposition of the separating piston in the region of the partition the pump suction tube can be accommodated by the recess. The device may be made as a modular system in which major components are made as a standard module, and other functional components, such as the oil reservoir chamber and the gas spring chamber are made as variable modules according to particular needs. The modules can be separately disposed and interconnected by tubular conduits.
