Patent EP-0024946-A2 (EP)
Inventor: GIACHINO JOSEPH MARIO
IPC: H01L29/84
Filed: 1980-09-03
Abstract: A method for manufacturing capacitor assemblies for variable capacitance pressure transducers comprises removing portions of material removed from spaced areas of a wafer (12) of doped silicon or other semiconductor material to form a plurality of recesses (18) in the surface of the semiconductor material. The material is doped to enhance its electrical conductivity. A dielectric material (14) has one of its surfaces (20) coated with spaces areas (22) of electrically conductive material. The semiconductor material (12) is attached to the coated surface of the dielectric material (14) such that the surface recesses in the semiconductor material are in alignment with the conductive areas on the dielectric material. This produces a plurality of electrical capacitors suitable for use as pressure transducers. The capacitance of these transducers is varied as a function of changes in one or more fluid pressures acting on the plates of each of the capacitors, one of these plates being the doped semiconductor material and the other being a conductive area on the dielectric material. Fluid pressure between the plates may be established during manufacture through holes (26) in the dielectric material, which may also be lined with conductive material and then sealed (34, 36) to provide electrical contacts to the capacitor plates. The capacitor assembly produced by this process may then be cut into a plurality of separate pressure transducers

Abstract: Process for electrostatically coating objects with a fluid, for instance liquid paint, by applying a high voltage to a spray bell and by feeding the fluid to a revolving, driven spray bell. The flow-rate of the fluid supplied to the center of the spray bell is decelerated nearly to zero when it enters the bell, then the rate of the fluid is increased by being accelerated by the bell to 15,000 to 60,000 rpm, and the fluid thereupon is centrifuged off the spray rim of the bell and is guided to the object to be coated.

Abstract: in a method and apparatus for compressing digital data derived from an image, a prediction table, which is pregenerat- ed based on a number of sample images, generates a predicted pixel and source state for each pixel of the original image, as the original image is scanned. The predicted pixel is the expected value of the pixel when considering the values of a group of adjoining pixels, while the source state is indicative of the probability that the predicted pixel is in error. Prediction error pixels are then generated and grouped according to their respective source states to form a plurality of run length symbols with each symbol comprising a white portion and a black portion, which symbols are stored sequentially in order of formation in a memory device (25) according to their respective source states. The symbols are used to provide address data for a memory device (85) which generate variable length code words that are transmitted to a receiving station and decoded using the reverse of the aforementioned process to form a facsimile image.

Abstract: An improved semiconductor device having a diffused region of reduced length and an improved method of fabricating such a semiconductor device are disclosed. The semiconductor device may be a MOSFET or an IGR, by way of example. In a form of the method for fabricating a MOSFET, an N +  SOURCE (66) is diffused into a P BASE (56) through a window of a diffusion mask. An anisotropic or directional etchant is applied to the N +  SOURCE through the same window. The etchant removes most of the N +  SOURCE, but allows shoulders (72) thereof to remain intact. These shoulders, which form the completed N +  SOURCE regions, are of reduced length, greatly reducing the risk of turn-on of a parasitic bipolar transistor in the MOSFET. The risk of turn-on of a parasitic bipolar transistor in an IGR is similarly reduced, when the IGR is fabricated by the improved method.

Abstract: An analog/digital control system for a tractor. In the system is performed the measurement of a factor, or factors, dominating the work performance of the tractor's lifting attachment or of the actuator of a work implement. In this way is formed the actual value signal of the control system and its set-point signal (a), and the signal (e) stating their difference, on the basis of the latter being governed an analog/digital control unit, which governs the control means of the actuator, such as a solenoid valve (16,22,23). The control deviation signal in analog form is transformed into digital form by the sampling in order to establish a so-called dead range in the time dimension. The digital signal is processed in comparator members (9,12), in which have been set the limit values (Ty,Ta) defining the dead range. When in the sampling procedure the pulse amplitudes fall once or several times outside the dead range (Ty-Ta), such influence is exerted on the sampling means that transition is made to continuous following of the control deviation and in this manner the requisite control measures are carried out. When a value (e 2 ) derived from the control deviation falls in the dead range (Ty-Ta), transition is made back to the sampling procedure.
