Abstract: A totally self-checking memory cell array apparatus (30) has an array (31)of memory cells (32) selectively addressed by row and column decoders (33, 35) which receive unidirectional error detecting code signals as address inputs (34,36). Data, as a multiple bit data word (A, B, C₁, C₂), is stored in the array (31) in unidirectional error detecting code form. Cells in each row (1-8) of the array have two separate row select connection lines (45 and 45a) for coupling the cell to data and data complement (46, 46*) connections. Error detection circuits (44, 47) are provided which determine errors by comparing the data and data complement lines for each data bit read out of the array and for detecting when multiple bit data words read out of the array are not coded in a unidirectional error detecting code format. The above apparatus provides error indications in case of any unidirectional errors in the row or column input address signals or the row or column decoders, or any unidirectional error corruption of the data stored in the memory cell array. This is achieved without completely duplicating each memory cell in the array and all row and column decoder circuitry.

Abstract: A ventilation box for a masonry wall has mutually separated ducts for incoming air and outgoing air, each of which can be closed by means of a nonreturn flap, namely an incoming air flap and an outgoing air flap. Incoming air flap and outgoing air flap are pivotably mounted separately and independently of one another, but connected to the outgoing air flap is a locking member which, in the closed position of the outgoing air flap, projects into the pivot path of the incoming air flap and locks the latter in the closed position and, on opening of the outgoing air flap, releases the incoming air flap for the opening movement. The locking element can at the same time be designed as a compensating weight for the outgoing air flap. <IMAGE>

Abstract: A scheme for maintaining current balance within a plurality of semiconductor devices, particularly thyristors and gate turn-off thyristors, which plurality is connected between two electrical power sources, which devices are configured to be simult­aneously conductive to share the current between the two sources. The scheme provides for the generation of individual current signals which represent the individual current magnitudes (I ind ) within the several devices. Further generated is an average current signal (I avg ) representing the average current within the plurality. A difference signal is generated (58) with respect to each of the individual current signals which represents the difference between the average and the individual current signal. The difference signal is then employed to vary (46) the time of application of the next control signal to the associated one of the devices to thereby minimize current imbalance within the plurality.

Title: Method to prevent backside growth on substrates in a vapor deposition system
Inventor: GOELA JITENDRA SINGH
IPC: C23C16/458
Filed: 1990-08-30
Abstract: A method of preventing backside growth on substrates in a vapor deposition system wherein the substrate (10) is mounted on a plurality of graphite pillars (16) with the pillars being bonded to the substrate as near the periphery thereof as possible. A hollow body (14) open on one side but closed on the other, and fabricated from flexible graphite suitably with graphite cement used as a bonding agent, is mounted on the pillars with the open end facing the substrate. The open end of the hollow body is pressed against the substrate and sealed with a bonding agent. This completely covers the backside of the substrate and thus prevents any vapor deposition thereon. Vapor deposition occurs, however, on the outer surface of the hollow graphite body. Since the graphite is quite flexible, the material coated or deposited thereon, for example silicon (Si), is readily broken into small pieces by using a piercing tool and a pair of pliers. Cracks developed in the coated hollow body do not propagate to the substrate because the substrate is perpendicular to the body, and the flexible graphite deforms as stresses develop due to material growth and thermal expansion mis­match.

Abstract: A four-wire system is disclosed for communicating between the host station and several remote stations. A first pair of wires is employed across which the remote stations are coupled in shunt, and over which the host station addresses the particular remote station with which it wishes to communicate, and supplies power to the several remote stations. The remote stations are coupled in shunt to a second pair of wires and transmit real time analog information to the host station over the second pair of wires. Each remote station includes a receiving section, which determines whether an address appearing on the first pair of wires corresponds to the particular remote station, and if so, activates power to a transmitting section therein. The transmitting section responds to control information extracted by the receiving section from the address and transmits selected real time information back to the host station over the second pair of wires by way of a differential voltage format. The control information includes instructions as to the source of real time information to be transmitted by the transmitting section to the host station.

Abstract: In the case of a target-directed drilling rod having at least one pair of inclination controllers for controlling hydraulic corrective drives, in which a measuring system establishes the controlled variable as angle of inclination of the target-directed drilling rod in a plane against the predetermined drilling axis in both directions and the control system converts the measured values into manipulated variables for the oppositely acting corrective drives arranged in the plane, the invention provides that, in the measuring system (31, 32), the inclination sensor (29, 30) is designed as an accelerometer, which delivers a permanent, electronic measuring signal to a filter (33), which suppresses the oscillations of the target-directed drilling rod and supplies the controlled variable, which has been corrected by the temperature-dependent offset drift of the inclination sensor (29, 30) and passes via a signal amplifier (34) to a window discriminator (35), which emits the controlled variable through a control window, designed according to angular minutes of the inclination and as a three-step controller, to power output stages (36, 37), which pass on electrical manipulated variables to solenoid valves (38, 39). <IMAGE>

IPC: G01M3/36

Abstract: This invention detects leaks in small, hermetically sealed packages, especially microchips or other packages of electronic circuits. To detect gross leaks, one places the package (9) in a chamber (5), and varies the pressure in the chamber slightly. If the leak is not too big, one wall of the package, such as its lid, initially becomes deformed, but quickly returns to its original position, due to the leak. If the leak is very large, the wall of the package may not move at all. The position of the wall is monitored with an interferometer, preferably an electronic shearography apparatus (17). To detect fine leaks, the package (9) is placed in the chamber (5) and the pressure is changed substantially, thus causing the walls of the package to deform. If there is a fine leak, a deformed wall gradually returns to its initial position. This gradual return can be measured by the interferometer (17), and the rate at which the wall returns to its starting position can be used to calculate the leak rate.
