Patent AT-E73578-T1 (AT)
Inventor: PRICE WILLIAM L
IPC: H01L21/308
Filed: 1985-11-04
Granted: 1992-03-15
Abstract: An improved process is disclosed for making an integrated circuit structure wherein a trench is etched into one or more layers to electrically separate one of the devices in the integrated circuit structure from other portions thereof by first patterning silicon dioxide and silicon nitride layer on a layer of silicon. The improvement comprises isotropically etching the silicon layer to provide an enlarged shallow etch area undercutting the patterned silicon dioxide and silicon nitride layers. Subsequent deeper anisotropic etching to form the trench will result in a trench having an enlarged upper width which, in turn, prevents the formation of voids adjacent the upper portion of the trench during subsequent oxidation and polysilicon deposition steps. Possible creation of openings to such voids in the polysilicon during subsequent planarization is thereby eliminated thus avoiding undesirable oxidation of such voids and undesirable stress formation therefrom.

Abstract: A hearing aid including a microphone for generating an electrical output from sounds external to a user of the hearing aid, an electrically driven receiver for emitting sound into the ear of the user of the hearing aid, and circuitry for driving the receiver. The circuitry drives the receiver in a self-generating mode activated by a first set of signals supplied externally of the hearing aid to cause the receiver to emit sound having at least one parameter controlled by the first set of externally supplied signals and then drives the receiver in a filtering mode, activated by a second set of signals supplied externally of the hearing aid, with the output of the external microphone filtered according to filter parameters established by the second set of the externally supplied signals. Other forms of the hearing aid, apparatus for supplying the sets of signals to the hearing aid in a total system, and methods of operation are also described.

Abstract: A remote actuating mechanism, in particular for actuating a control lever of a three-point implement hitch, has a transmission unit with a slide which is movable longitudinally by means of a swingable driver. The driver can be held in an inoperative position and has a spring-loaded driving pin by means of which a positive connection can be obtained between the driver and the transmission unit in any position of the slide. The positive connection is possible, however, only in a single spatial relationship between the driver and the slide. In the inoperative position, the driver is separated from the slide and a lock is provided to prevent unintentional actuation.

Abstract: A computer-controlled system for transporting workpieces, in which each workpiece is placed on a load carrier, each workpiece and load carrier being marked with an identifier. A central computer is loaded with data relative to each given workpiece, its respective load carrier, and work to be performed on such workpiece, and predetermines a path to be followed by such load carrier. The load carrier is placed on a main path, its identifier is read, and if work is to be performed on a workpiece carried thereon, a switch is thrown to divert the load carrier to an auxiliary path and then to a work station. The load carrier may be diverted to the work station by a swing-out device or by a spur path, for example. After such work, the load carrier is returned to the main path and its identifier is read again to determine whether it again is to be diverted to an auxiliary path for performing further work on a workpiece carried thereon. Holding devices are provided on the main and auxiliary paths for performing sorting and accumulating functions to optimize passage times around the system.
