摘要： A redundant memory circuit having a memory for storing information in a matrix of interconnected rows and columns, and a row and a column address decoder to access the rows and columns. The memory has a redundant row or rows to replace a defective row or rows in the matrix and a programmable decoder which is programmed with the row address of the defective row to access the redundant row. The row and column address decoders are used to access the defective row and to sequentially access the columns so as to entirely disconnect the defective row from the columns. The programmable decoder is then programmed with the defective row address, bit by bit, in response to the column addresses, to access the redundant row. After this procedure, a verification circuit can be used to verify that the redundant row can be accessed and that the programmable decoder is properly programmed to decode only one address to one row.

摘要： A noise discriminator circuit and a noise discrimination method in a burst mode receiver is configured to determine the validity of an incoming burst signal by analyzing the timing of the signal edges of incoming signal to look for a time duration conforming to the preamble data bits of a valid burst signal. In one embodiment, the noise discriminator circuit and method analyze the time duration between signal edges of the same pulse of an incoming signal. In another embodiment, the noise discriminator circuit and method analyze the time duration between a first set of pulses of an incoming signal and the time duration between signal edges of a second set of pulses of the incoming signal. When the time durations are within a given time range relating to a predetermined timing separation of a valid burst signal, the incoming signal is validated as a valid burst signal.

摘要： A gate valve includes a body which includes first and second valve seats. First and second gates are mounted for movement adjacent to the valve seats, and each of the gates has an outer face adapted to seal against the respective valve seat and an inner face which defines a thrust pad. A wedge is interposed between the first and second gates, and the wedge defines first and second converging wedge faces rigidly positioned with respect to one another to bear against the respective thrust pads. At least one of the thrust pads and the wedge faces defines a convex surface. A hand wheel axially moves the wedge with respect to the body and the wedge is coupled to the gates such that movement of the wedge away from the valve seats moves the gates away from the valve seats. The convex surface allows the respective gate to articulate with respect to the wedge as necessary to align with the valve seat. The wedge is coupled to an actuating member shaped to abut the gates, and springs are placed between the wedge and the gates to bias the gates into contact with the actuating member.

摘要： A laser bias control and monitoring circuit receives a monitor diode current on an input node and generate a bias current for a laser diode on an output node where the monitor diode current flows into (positive polarity) or out of (negative polarity) the input node. The laser bias control and monitoring circuit includes a polarity independent current sensing circuit configured to receive the monitor diode current in either positive or negative polarity and to generate a normalized output current having a magnitude proportional to a magnitude of the monitor diode current. In this manner, the laser bias control and monitoring circuit can be used with laser diode and monitor diode combination in either the common anode or the common cathode configuration, or with the monitor diode current being provided from the anode or cathode of the monitor diode. No reprogramming or reconfiguration of the circuit is required.

摘要： A temperature control system for a forehearth, said forehearth for thermally conditioning molten glass to be fed to a glassware forming machine, and being divided into a plurality of zones. Each of the forehearth zones is provided with devices for monitoring the temperature of molten glass within the zone, and apparatus for selectively heating the glass. A microprocessor-based time sharing system controls the temperature of the plurality of zones, using adaptive control loops. Each zone is assigned a time period for monitoring temperature and taking appropriate corrective action. Temperature adjustments may be made independently zone-by-zone, or in cooperation, and other physical parameters may be taken into account such as glass viscosity or combustion pressure. Certain time-sharing periods may be associated with monitoring and displaying functions only.
