Patent number: 5279040Abstract: A sensor (10) for measurement of acceleration and/or tilt of a movable object, particularly a motor vehicle, features an interior space (12) partially filled with fluid (15). Within that space, at least two heatable, temperature-sensitive electrical circuit elements are arranged so that, in a rest or initial position of the sensor, they are equally covered or wetted by the fluid. If the acceleration and tilt of the movable object are both zero, or the two cancel each other out, the sensor reading is zero. If this is not the case, the acceleration or tilt leads to a differing degree of coverage or wetting of the at least two circuit elements, and thus to a non-zero sensor reading.Type: GrantFiled: June 10, 1992Date of Patent: January 18, 1994Assignee: Robert Bosch GmbHInventors: Ulrich Kippelt, Botho Ziegenbein, Gunther Stecher

Patent number: 5186051Abstract: A device for measuring a flowing air quantity is proposed which comprises a sensor element which is exposed to the flowing air, is constructed in thick-film technology and contains a heating film resistor (R.sub.H), which is arranged on an insulating substrate (10) and through which current flows, and a sensor film resistor (R.sub.S) which is likewise arranged on the insulating substrate (10), serves to sense the temperature of the heating film resistor (R.sub.H) and is a component of a bridge circuit. The heating film resistor (R.sub.H) and the sensor film resistor (R.sub.S), separated from one another by an intermediate film (13) which is a good conductor of heat but is electrically insulating, are accommodated in a bubble (11) which is made of ceramic material, in particular of glass ceramic, and is arched on the insulating substrate (10). The thin diaphragm (14) made of a ceramic material ensures effective thermal uncoupling of the film resistors (R.sub.H, R.sub.S) from the insulating substrate (10).Type: GrantFiled: February 27, 1991Date of Patent: February 16, 1993Assignee: Robert Bosch GmbHInventors: Gunther Stecher, Hans Hecht, Dietrich Bergfried, Botho Ziegenbein, Richard Muehlheim

Patent number: 5172466Abstract: A PTC temperature sensor and a process for producing PTC temperature sensing elements from ceramic films for a PTC temperature sensor are proposed. The PTC temperature sensing elements are so designed that the PTC resistor track is hermetically encapsulated with respect to the gas being measured and the ambient air. Ceramic films based on an insulator ceramic, in particular based on Al.sub.2 O.sub.3, and ceramic films based on a solid electrolyte can be used to produce the temperature sensing elements. The PTC temperature sensor according to the invention is distinguished, in particular, by the fact that, while the manufacturing procedure is cheap, it is not subject to aging due to the effect of varying O.sub.2 partial pressures, has a high resistance to aging of the resistance characteristic in rich and lean gas mixtures, for example in motor vehicle exhaust gases, at 300.degree.-1000.degree. C.Type: GrantFiled: June 14, 1991Date of Patent: December 22, 1992Assignee: Robert Bosch GmbHInventors: Karl-Hermann Friese, Hans-Martin Wiedenmann, Gunther Stecher

Patent number: 5142266Abstract: The NTC temperature sensor includes a NTC temperature sensing element having an NTC resistor and made of a laminated composite of ceramic films, which is so designed that the ambient air or oxygen supplied by electrolytic pumping has free access, via a channel in the laminated composite, to the NTC resistor. The NTC resistor is hermetically sealed from a gas being measured. Solid electrolyte films which conduct O.sup.-2 ions, and films based on Al.sub.2 O.sub.3 can be used to make the laminated composite. The NTC resistor characteristic curve is independent of the composition of the gas being measured. The laminated composite can be formed of at least three solid electrolyte ceramic films including a base film provided with punched-out interconnection holes and conductor tracks printed by thick film technology, an intermediate film having a punched-out channel and a channel enlargement around the ends of the conductor tracks forming the electrodes of the NTC resistor, and a covering film.Type: GrantFiled: March 26, 1990Date of Patent: August 25, 1992Assignee: Robert Bosch GmbHInventors: Karl-Hermann Friese, Gunther Stecher, Hans-Martin Wiedenmann

Patent number: 4816200Abstract: A free-standing, self-supporting layer of glass-ceramic or crystallized glass is applied by thick-film technology over a presintered layer made of a vaporizable or etchable material which, after sintering the thick-flim glass-ceramic or crystallized glass layer (3) to a substrate (1), is removed by heating or etching. The layer (2) to be removed is preferably applied in paste form with the glass-ceramic thick-film layer (3) thereover either in form of a crossing bridge, as a partially covering cantilever, or entirely surrounding the layer 2, in which latter case the thick-film layer (3) is of porous construction so that the volatile or vaporizable components of the underlying layer (2) can escape through the thick-film layer (3). A typical layer which is volatile or vaporizable includes carbon black, a resin binder and a solvent, applied to a substrate, for example of ceramic or enameled metal, over which the glass-ceramic layer is applied.Type: GrantFiled: August 27, 1982Date of Patent: March 28, 1989Assignee: Robert Bosch GmbHInventors: Gunther Stecher, Herbert Zimmermann

Patent number: 4722227Abstract: The high pressure sensor includes a housing part, a lid closing the same and an intermediary disposed sensor disk. A cylindrical pressure chamber is formed in the housing, wherein an inner area of the sensor disk is disposed in a sealed off manner. In this area the measuring sensors are disposed in form of piezoresistive layer resistors. Layer conductors penetrate from this inner area into an outer area, wherein evaluation circuits and the evaluation electronic are disposed. The total sensor disk is provided with one or a plurality of glass layers in such a manner that a flat surface is obtained. Pressure changes of the pressure medium are picked up in the pressure chamber by the measuring sensors and are processed accordingly. Such a high pressure sensor is relatively simple and advantageous in its use.Type: GrantFiled: April 22, 1986Date of Patent: February 2, 1988Assignee: Robert Bosch GmbHInventors: Alfred Grob, Wolfgang Leibfried, Karl Rampmaier, Kurt Spitzenberger, Gunther Stecher, Klaus Steinle, Heinz Walter, Herbert Zimmermann

Patent number: 4382247Abstract: A deformable membrane is made by applying, by thick-film technology, a glass-ceramic paste over a vaporizable or burnable filler material, containing primarily carbon black in a binder which, in turn, is located on a substrate, for example of ceramic, glass, enameled metal or the like. The substrate for example is about 1.5 cm square, the membrane glass ceramic being applied as a circular dot of about 0.5 cm diameter. After solidifying the paste forming the membrane in a protective gas atmosphere, for example at about 950.degree. C., the filler is burned out in an oxidizing atmosphere, to escape through pores in the membrane material. By selecting a membrane material which has a lower thermal coefficient of expansion than that of the substrate, after burning, the membrane will assume a convex shape leaving a hollow space (8) beneath it and the substrate.Type: GrantFiled: August 27, 1980Date of Patent: May 3, 1983Assignee: Robert Bosch GmbHInventors: Gunther Stecher, Kurt Spitzenberger, Klaus Muller

Patent number: 4294679Abstract: To apply a measured quantity of air to the electrodes applied to a plate-like solid electrolyte body, which may be a chip on a carrier or may, itself, form the carrier, grooves, flutes, ducts, or depressions are formed in the carrier and/or a cover plate, the grooves terminating at an edge portion with access to the gas to be supplied, and having a size such that their clear height is preferably in the lower micron region, and a width, preferably under 1 mm, and particularly between 0.2 and 0.4 mm. The higher limits are applicable to apply, for example, air to a reference electrode, to apply ambient oxygen thereto; the lower limits are appropriate when operating the sensor as a polarographic sensor, in which the diffusion limited current, upon application of a bias voltage, is an analog measure of the oxygen concentration in the gas, and the gas supply to the electrode must be suitably controlled to prevent saturation conditions.Type: GrantFiled: May 1, 1980Date of Patent: October 13, 1981Assignee: Robert Bosch GmbHInventors: Helmut Maurer, Klaus Muller, Ernst Linder, Franz Rieger, Gunther Stecher
