Patent EP-0429122-A1 (EP)
Inventor: DE POORTER JOHANNES ANTONIUS
IPC: H01J37/244
Filed: 1990-11-12
Abstract: A degree of contamination can be measured in a charged particle beam system by means of a contamination monitor which is provided with a carrier (3) having an aperture for transmitting a charged particle beam (7) and a membrane (5) which is connected to the carrier and which covers the aperture. The thickness of a contamination layer deposited on the membrane can be determined by measurement of a decrease of the transmission of the membrane as the contamination increases. The accuracy of measurement is enhanced by selecting a central portion of the particle beam transmitted by the membrane.

Abstract: A method for making a semiconductor device with a bipolar transistor utilizes an amorphous silicon layer as a diffusion source. The layer is successively implanted with boron and arsenic ions. In a single annealing step, dopants are then simultaneously out-diffused from the layer to form both base (34) and emitter (32) regions in an underlying monocrystalline silicon body.

Abstract: In a radio-frequency plasma deposition reactor (10), SiO₂ is deposited from a source (16) of tetraethoxysilane (TEOS). The deposition is made to be anisotropic, that is, to be deposited preferentially on horizontal surfaces, by use in the deposition atmosphere of a constituency such as NH₃ or NF₃ which inhibits SiO₂ deposition, along with a radio-frequency power in excess of 100 watts, which preferentially removes the inhibiting gas from horizontal surfaces through ion impact.

Title: Brake actuator
Inventor: URBAN JOHN ARTHUR
IPC: F16D65/22
Filed: 1990-10-24
Abstract: A brake actuator has a housing (7) containing tappets (13, 14) operable by a cam (8) to apply brake shoes (5, 6) against a rotary brake drum. The housing defines a cavity to which lubricant is admitted through means (17). A non-compressible flexible element (30) is disposed within the cavity and subject to lubricant pressure. The element (30) is movable during outward movement of the tappets to compensate for any increase in volume of the cavity caused by tappet outward movement. This avoids the occurrence of negative pressure in the cavity.

Abstract: A programmable cell (70) for use in programmable logic devices utilizes CMOS SRAM technology. True and complement cells are paired, and generate a signal which can be combined with other such signals to give a product term. SRAM bits store program information, and drive the generated signal as a function of values at its true and complementary inputs. The generated signal goes through a full CMOS voltage swing, so that no sense amplifiers are required for the product term.

Abstract: Les alliages d'aluminium et de lithium artificiellement vieillis reçoivent un traitement thermique auxiliaire à la fin du vieillissement, ou après celui-ci, afin d'améliorer les caractéristiques de leur section transversale courte, et notamment leur ténacité à la rupture. Le traitement thermique auxiliaire consiste à chauffer le matériau de façon régulière jusqu'à une température d'inversion supérieure à la température de vieillissement d'au moins 20 °C mais ne dépassant pas 250 °C, à maintenir le matériau à cette température pendant une courte période, puis à le refroidir jusqu'à la température ambiante. Normalement, le traitement consiste à chauffer le matériau jusqu'à une température d'inversion comprise entre 190 et 230 °C et à le maintenir à cette température pendant environ 5 minutes. Les caractéristiques intensifiées se dégradent lors de l'exposition prolongée aux températures égales ou supérieures à 60 °C, mais peuvent être restituées par une répétition du traitement thermique auxiliaire.

Inventor: KUBIS HERIBERT DIPL-ING
IPC: F01L13/06
Filed: 1991-01-18
Abstract: The invention relates to an engine brake for air compressing engines. To increase the braking power, the exhaust valve (1) is raised slightly even during the compression stroke, allowing additional braking work to be performed by the piston by virtue of the restricting effect of the exhaust valve. A hydraulic linkage (4) is inserted between the cam (2) and the exhaust valve (1) for the purpose of raising the exhaust valve. According to the invention, this linkage is activated in the braking mode by the closure, during the compression stroke, of a solenoid valve (12) connected in parallel with the linkage. The solenoid valve is controlled via sensors (20, 21) with the interposition of a control unit (19), the sensors interacting with the flywheel (23). By means of the closed position of the solenoid valve in braking mode, the exhaust valve can be raised by a second lobe of the cam in the compression stroke as well. By virtue of this measure, braking work is performed not only during the exhaust stroke but also during the compression stroke.

Abstract: In the case of a hydraulic brake system with antilock and wheel slip control device, the filling of a line on the outlet side of a leakage-free pump is to be facilitated. The hydraulic brake system 1 has a hydraulic unit (30) and a pump unit (35) of an antilock and wheel slip control device (48). The pump unit (35) has a leakage-free pump (36) for drawing pressure medium from a pressure medium storage tank (3) of a master brake cylinder (2) of the brake system (1) and delivering it through a connecting line (40) into the hydraulic unit (30). A bypass line (42) with a throttle (44) is arranged parallel to the pump (36). Following evacuation pressure medium is fed into the brake system (1) from the storage tank (3), which fills the connecting line (40) on the outlet side of the pump (36) through the bypass line (42). A filling bore (31) previously necessary with air bleed screw (32) in the hydraulic unit (30) for filling this connecting line (40) can be dispensed with.
